Clinical outcomes of uninterrupted embryo culture with or without time-lapse-based embryo selection versus interrupted standard culture (SelecTIMO): a three-armed, multicentre, double-blind, randomised controlled trial.

BACKGROUND: Time-lapse monitoring is increasingly used in fertility laboratories to culture and select embryos for transfer. This method is offered to couples with the promise of improving pregnancy chances, even though there is currently insufficient evidence for superior clinical results. We aimed to evaluate whether a potential improvement by time-lapse monitoring is caused by the time-lapse-based embryo selection method itself or the uninterrupted culture environment that is part of the system. METHODS: In this three-armed, multicentre, double-blind, randomised controlled trial, couples undergoing in-vitro fertilisation or intracytoplasmic sperm injection were recruited from 15 fertility clinics in the Netherlands and randomly assigned using a web-based, computerised randomisation service to one of three groups. Couples and physicians were masked to treatment group, but embryologists and laboratory technicians could not be. The time-lapse early embryo viability assessment (EEVA; TLE) group received embryo selection based on the EEVA time-lapse selection method and uninterrupted culture. The time-lapse routine (TLR) group received routine embryo selection and uninterrupted culture. The control group received routine embryo selection and interrupted culture. The co-primary endpoints were the cumulative ongoing pregnancy rate within 12 months in all women and the ongoing pregnancy rate after fresh single embryo transfer in a good prognosis population. Analysis was by intention to treat. This trial is registered on the ICTRP Search Portal, NTR5423, and is closed to new participants. FINDINGS: 1731 couples were randomly assigned between June 15, 2017, and March 31, 2020 (577 to the TLE group, 579 to the TLR group, and 575 to the control group). The 12-month cumulative ongoing pregnancy rate did not differ significantly between the three groups: 50·8% (293 of 577) in the TLE group, 50·9% (295 of 579) in the TLR group, and 49·4% (284 of 575) in the control group (p=0·85). The ongoing pregnancy rates after fresh single embryo transfer in a good prognosis population were 38·2% (125 of 327) in the TLE group, 36·8% (119 of 323) in the TLR group, and 37·8% (123 of 325) in the control group (p=0·90). Ten serious adverse events were reported (five TLE, four TLR, and one in the control group), which were not related to study procedures. INTERPRETATION: Neither time-lapse-based embryo selection using the EEVA test nor uninterrupted culture conditions in a time-lapse incubator improved clinical outcomes compared with routine methods. Widespread application of time-lapse monitoring for fertility treatments with the promise of improved results should be questioned.

Treatment effect of oil-based contrast is related to experienced pain at HSG: a post-hoc analysis of the randomised H2Oil study.

STUDY QUESTION: Does pain or volume of used contrast medium impact the effectiveness of oil-based contrast during hysterosalpingography (HSG)? SUMMARY ANSWER: In women who report moderate to severe pain during HSG, the use of oil-based contrast resulted in more ongoing pregnancies compared to the use of water-based contrast, whereas in women who reported mild or no pain, no difference in ongoing pregnancies was found. WHAT IS KNOWN ALREADY: We recently showed that in infertile women undergoing HSG, the use of oil-based contrast results in more ongoing pregnancies within 6 months as compared to the use of water-based contrast. However, the underlying mechanism of this fertility-enhancing effect remains unclear. STUDY DESIGN, SIZE, DURATION: We performed a post-hoc analysis of the H2Oil study, a multicentre randomised controlled trial (RCT) evaluating the therapeutic effect of oil- and water-based contrast at HSG. Here, we evaluated the impact of pain experienced at HSG and volume of used contrast media during HSG on ongoing pregnancy. PARTICIPANTS/MATERIALS, SETTING, METHODS: In a subset of 400 participating women, pain during HSG by means of the Visual Analogue Scale (VAS) (range: 0.0-10.0 cm) was reported, while in 512 women, we registered the volume of used contrast (in millilitres). We used logistic regression analyses to assess whether pain and volume of used contrast media modified the effect of oil-based contrast on ongoing pregnancy rates. Data were analysed according to intention-to-treat principle. MAIN RESULTS AND THE ROLE OF CHANCE: In 400 women in whom pain scores were reported, the overall median pain score was 5.0 (Interquartile range (IQR) 3.0-6.8) (oil group (n = 199) 4.8 (IQR 3.0-6.4); water group (n = 201) 5.0 (IQR 3.0-6.7); P-value 0.28). There was a significant interaction between pain (VAS ≤5 versus VAS ≥6) and the primary outcome ongoing pregnancy (P-value 0.047). In women experiencing pain (VAS ≥6), HSG with oil-based contrast resulted in better 6-month ongoing pregnancy rates compared to HSG with water-based contrast (49.4% versus 29.6%; RR 1.7; 95% CI, 1.1-2.5), while in women with a pain score ≤5, 6-month ongoing pregnancy rates were not significantly different between the use of oil- (28.8%) versus water-based contrast (29.2%) (RR 0.99; 95% CI, 0.66-1.5). In the 512 women in whom we recorded contrast, median volume was 9.0 ml (IQR 5.7-15.0) in the oil group versus 8.0 ml (IQR 5.9-13.0) in the water group, respectively (P-value 0.72). Volume of used contrast was not found to modify the effect of oil-based contrast on ongoing pregnancy (P-value for interaction 0.23). LIMITATIONS, REASONS FOR CAUTION: This was a post-hoc analysis that should be considered as hypothesis generating. The RCT was restricted to infertile ovulatory women, younger than 39 years of age and with a low risk for tubal pathology. Therefore, our results should not be generalised to infertile women who do not share these features. WIDER IMPLICATIONS OF THE FINDINGS: The underlying mechanism of the fertility-enhancing effect induced by HSG with the use of oil-based contrast remains unclear. However, these findings suggest a possible mechanistic pathway, that is increasing intrauterine pressure occurring prior to dislodging pregnancy hindering debris or mucus plugs from the proximal part of otherwise normal fallopian tubes. This information might help in the search of the underlying fertility-enhancing mechanism found by using oil-based contrast during HSG.

The vaginal microbiome as a predictor for outcome of in vitro fertilization with or without intracytoplasmic sperm injection: a prospective study.

STUDY QUESTION: Is the presence or absence of certain vaginal bacteria associated with failure or success to become pregnant after an in vitro fertilization (IVF) or IVF with intracytoplasmic sperm injection (IVF-ICSI) treatment? SUMMARY ANSWER: Microbiome profiling with the use of interspace profiling (IS-pro) technique enables stratification of the chance of becoming pregnant prior to the start of an IVF or IVF-ICSI treatment. WHAT IS KNOWN ALREADY: Live-birth rates for an IVF or IVF-ICSI treatment vary between 25 and 35% per cycle and it is difficult to predict who will or will not get pregnant after embryo transfer (ET). Recently, it was suggested that the composition of the vaginal microbiota prior to treatment might predict pregnancy outcome. Analysis of the vaginal microbiome prior to treatment might, therefore, offer an opportunity to improve the success rate of IVF or IVF-ICSI. STUDY DESIGN, SIZE, DURATION: In a prospective cohort study, 303 women (age, 20-42 years) undergoing IVF or IVF-ICSI treatment in the Netherlands were included between June 2015 and March 2016. PARTICIPANTS/MATERIALS, SETTING, METHODS: Study subjects provided a vaginal sample before the start of the IVF or IVF-ICSI procedure. The vaginal microbiota composition was determined using the IS-pro technique. IS-pro is a eubacterial technique based on the detection and categorization of the length of the 16S-23S rRNA gene interspace region. Microbiome profiles were assigned to community state types based on the dominant bacterial species. The predictive accuracy of the microbiome profiles for IVF and IVF-ICSI outcome of fresh ET was evaluated by a combined prediction model based on a small number of bacterial species. From this cohort, a model was built to predict outcome of fertility treatment. This model was externally validated in a cohort of 50 women who were undergoing IVF or IVF-ICSI treatment between March 2018 and May 2018 in the Dutch division of the MVZ VivaNeo Kinderwunschzentrum Düsseldorf, Germany. MAIN RESULTS AND THE ROLE OF CHANCE: In total, the vaginal microbiota of 192 women who underwent a fresh ET could be analysed. Women with a low percentage of Lactobacillus in their vaginal sample were less likely to have a successful embryo implantation. The prediction model identified a subgroup of women (17.7%, n = 34) who had a low chance to become pregnant following fresh ET. This failure was correctly predicted in 32 out of 34 women based on the vaginal microbiota composition, resulting in a predictive accuracy of 94% (sensitivity, 26%; specificity, 97%). Additionally, the degree of dominance of Lactobacillus crispatus was an important factor in predicting pregnancy. Women who had a favourable profile as well as <60% L. crispatus had a high chance of pregnancy: more than half of these women (50 out of 95) became pregnant. In the external validation cohort, none of the women who had a negative prediction (low chance of pregnancy) became pregnant. LIMITATIONS, REASONS FOR CAUTION: Because our study uses a well-defined study population, the results will be limited to the IVF or IVF-ICSI population. Whether these results can be extrapolated to the general population trying to achieve pregnancy without ART cannot be determined from these data. WIDER IMPLICATIONS OF THE FINDINGS: Our results indicate that vaginal microbiome profiling using the IS-pro technique enables stratification of the chance of becoming pregnant prior to the start of an IVF or IVF-ICSI treatment. Knowledge of their vaginal microbiota may enable couples to make a more balanced decision regarding timing and continuation of their IVF or IVF-ICSI treatment cycles.

Total motile sperm count: a better indicator for the severity of male factor infertility than the WHO sperm classification system.

STUDY QUESTION: Does the prewash total motile sperm count (TMSC) have a better predictive value for spontaneous ongoing pregnancy (SOP) than the World Health Organization (WHO) classification system? SUMMARY ANSWER: The prewash TMSC shows a better correlation with the spontaneous ongoing pregnancy rate (SOPR) than the WHO 2010 classification system. WHAT IS KNOWN ALREADY: According to the WHO classification system, an abnormal semen analysis can be diagnosed as oligozoospermia, astenozoospermia, teratozoospermia or combinations of these and azoospermia. This classification is based on the fifth percentile cut-off values of a cohort of 1953 men with proven fertility. Although this classification suggests accuracy, the relevance for the prognosis of an infertile couple and the choice of treatment is questionable. The TMSC is obtained by multiplying the sample volume by the density and the percentage of A and B motility spermatozoa. STUDY DESIGN, SIZE, DURATION: We analyzed data from a longitudinal cohort study among unselected infertile couples who were referred to three Dutch hospitals between January 2002 and December 2006. Of the total cohort of 2476 infertile couples, only the couples with either male infertility as a single diagnosis or unexplained infertility were included (n = 1177) with a follow-up period of 3 years. PARTICIPANTS/MATERIALS, SETTING, METHODS: In all couples a semen analysis was performed. Based on the best semen analysis if more tests were performed, couples were grouped according to the WHO classification system and the TMSC range, as described in the Dutch national guidelines for male infertility. The primary outcome measure was the SOPR, which occurred before, during or after treatments, including expectant management, intrauterine insemination, in vitro fertilization or intracytoplasmic sperm injection. After adjustment for the confounding factors (female and male age, duration and type of infertility and result of the postcoital test) the odd ratios (ORs) for risk of SOP for each WHO and TMSC group were calculated. The couples with unexplained infertility were used as reference. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 514 couples did and 663 couples did not achieve a SOP. All WHO groups have a lower SOPR compared with the unexplained group (ORs varying from 0.136 to 0.397). Comparing the couples within the abnormal WHO groups, there are no significant differences in SOPR, except when oligoasthenoteratozoospermia is compared with asthenozoospermia [OR 0.501 (95% CI 0.311-0.809)] and teratozoospermia [OR 0.499 (95% CI: 0.252-0.988)], and oligoasthenozoospermia is compared with asthenozoospermia [OR 0.572 (95% CI: 0.373-0.877)]. All TMSC groups have a significantly lower SOPR compared with the unexplained group (ORs varying from 0.171 to 0.461). Couples with a TMSC of <1 × 10(6) and 1-5 × 10(6) have significantly lower SOPR compared with couples with a TMSC of 5-10 × 10(6) [respectively, OR 0.371 (95% CI: 0.215-0.64) and OR 0.505 (95% CI: 0.307-0.832)]. LIMITATIONS, REASON FOR CAUTION: To include all SOPs during the follow-up period of 3 years, couples were not censured at the start of treatment. WIDER IMPLICATIONS OF THE FINDINGS: Roughly, three prognostic groups can be discerned: couples with a TMSC <5, couples with a TMSC between 5 and 20 and couples with a TMSC of more than 20 × 10(6) spermatozoa. We suggest using TMSC as the method of choice to express severity of male infertility. STUDY FUNDING/COMPETING INTERESTS: None.

How long should we continue clomiphene citrate in anovulatory women?

STUDY QUESTION: What is the effectiveness of continued treatment with clomiphene citrate (CC) in women with World Health Organization (WHO) type II anovulation who have had at least six ovulatory cycles with CC but did not conceive? SUMMARY ANSWER: When women continued CC after six treatment cycles, the cumulative incidence rate of the ongoing pregnancy rate was 54% (95% CI 37-78%) for cycles 7-12. WHAT IS KNOWN ALREADY: If women with WHO type II anovulation fail to conceive with CC within six ovulatory cycles, guidelines advise switching to gonadotrophins, which have a high risk of multiple gestation and are expensive. It is however not clear what success rate could be achieved by continued treatment with CC. STUDY DESIGN, SIZE, DURATION: We performed a retrospective cohort study of women with WHO II anovulation who visited the fertility clinics of five hospitals in the Netherlands between 1994 and 2010. We included women treated with CC who had had at least six ovulatory cycles without successful conception (n = 114) after which CC was continued using dosages varying from 50 to 150 mg per day for 5 days. PARTICIPANTS/MATERIALS, SETTING, METHODS: Follow-up was a total of 12 treatment cycles. Primary outcome was the cumulative incidence rate of an ongoing pregnancy at the end of treatment. MAIN RESULTS AND THE ROLE OF CHANCE: We recruited 114 women that had ovulated on CC for at least six cycles but had not conceived. Of these 114 women, 35 (31%) had an ongoing pregnancy resulting in a cumulative incidence rate of an ongoing pregnancy of 54% after 7-12 treatment cycles with CC. LIMITATIONS, REASONS FOR CAUTION: Limitations of our study are its retrospective approach. WIDER IMPLICATIONS OF THE FINDINGS: Randomized trials comparing continued treatment with CC with the relatively established second line treatment with gonadotrophins are justified. In the meantime, we suggest to only begin this less convenient and more expensive treatment for women who do not conceive after 12 ovulatory cycles with CC. STUDY FUNDING/COMPETING INTERESTS: None. TRIAL REGISTRATION NUMBER: Not applicable.

Differences in quality of life and emotional status between infertile women and their partners.

STUDY QUESTION: Do the quality of life (QoL) and the risk factors for emotional problems during and after treatment of infertile women differ from their partners? SUMMARY ANSWER: Women have lower levels of fertility-related QoL, and more and differing risk factors for emotional problems during and after treatment than their partners. WHAT IS KNOWN ALREADY?: The psychological impact of infertility in patients negatively affects their QoL and is also related to increased discontinuation of treatment. Moreover, psychological factors might positively affect pregnancy rates. However, it is still unclear if differences in QoL and emotional status exist between infertile women and their partners. So far, research mainly focused on generic instruments to measure patients' QoL in the area of fertility care. STUDY DESIGN, SIZE, DURATION: A cross-sectional study of infertile couples within 32 Dutch fertility clinics. PARTICIPANTS/MATERIALS, SETTING, METHODS: We included infertile women and their partners (both heterosexual and lesbian couples) under any treatment and at any stage of treatment in one of the 32 participating clinics. Per clinic, 25-75 patients were randomly selected depending on clinic size. In total, 1620 women and their partners were invited separately to complete the FertiQoL and SCREENIVF questionnaires to measure their level of QoL and risk factors for emotional problems during and after treatment, respectively. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 946 women (response rate 58%) and 670 partners (response rate 41%) completed the questionnaire set. As 250 women and 150 partners were already pregnant, questionnaires from 696 women and 520 partners could be analysed. Women scored significantly lower on the FertiQoL total scores [B = -6.31; 95% confidence interval (CI) = -7.63 to 4.98] and three of the FertiQoL subscales (Emotional, Mind-Body and Social) than their partners, indicating lower QoL. Scores on the SCREENIVF questionnaire were significantly higher for women (B = 0.22; 95% CI = 0.06-0.38), indicating that women are more at risk for developing emotional problems (and these factors differed from those of their partners) during and after fertility treatment than their partners. LIMITATIONS, REASONS FOR CAUTION: Although the number of participants is high (n = 1216), the relatively low response rate, especially for partners (41%), may have influenced the results through selection bias. An analysis of non-responders could not be performed. The FertiQoL and SCREENIVF questionnaires, which have been validated only in women starting a first IVF cycle, should also be validated for studying partners. In addition, the SCREENIVF questionnaire has been validated in Dutch women only and further research in an international setting is also required. WIDER IMPLICATIONS OF THE FINDINGS: Our study results represent the Dutch infertile population as more than one-third of all Dutch clinics participated in the study. As the FertiQoL questionnaire is an internationally validated questionnaire already, these results can be put in a more broader and international perspective.

Risk of borderline and invasive ovarian tumours after ovarian stimulation for in vitro fertilization in a large Dutch cohort.

BACKGROUND: Long-term effects of ovarian stimulation for IVF on the risk of ovarian malignancies are unknown. METHODS: We identified a nationwide historic cohort of 19,146 women who received IVF treatment in the Netherlands between 1983 and 1995, and a comparison group of 6006 subfertile women not treated with IVF. In 1997-1999, data on reproductive risk factors were obtained from 65% of women and data on subfertility (treatment) were obtained from the medical records. The incidence of ovarian malignancies (including borderline ovarian tumours) through 2007 was assessed through linkage with disease registries. The risk of ovarian malignancies in the IVF group was compared with risks in the general population and the subfertile comparison group. RESULTS: After a median follow-up of 14.7 years, the risk of borderline ovarian tumours was increased in the IVF group compared with the general population [standardized incidence ratio (SIR) = 1.76; 95% confidence interval (CI) = 1.16-2.56]. The overall SIR for invasive ovarian cancer was not significantly elevated, but increased with longer follow-up after first IVF (P = 0.02); the SIR was 3.54 (95% CI = 1.62-6.72) after 15 years. The risks of borderline ovarian tumours and of all ovarian malignancies combined in the IVF group were significantly increased compared with risks in the subfertile comparison group (hazard ratios = 4.23; 95% CI = 1.25-14.33 and 2.14; 95% CI = 1.07-4.25, respectively, adjusted for age, parity and subfertility cause). CONCLUSIONS: Ovarian stimulation for IVF may increase the risk of ovarian malignancies, especially borderline ovarian tumours. More large cohort studies are needed to confirm these findings and to examine the effect of IVF treatment characteristics.

Anxiety and depression have no influence on the cancellation and pregnancy rates of a first IVF or ICSI treatment.

BACKGROUND: After many years of research, the impact of psychological distress on the IVF treatment outcome is still unclear. This study aimed to determine the influences of anxiety and depression before and during IVF or ICSI treatment on the cancellation and pregnancy rates of inductees. METHODS: In a multicentre prospective cohort study, we assessed anxiety and depression at baseline and the procedural anxiety level one day before oocyte retrieval, with the short versions of the State Anxiety Inventory (STAI) and the Beck Depression Inventory-Primary Care (BDI-PC). The effect of baseline anxiety and depression on the cancellation and pregnancy rates of 783 women in their first IVF or ICSI treatment was evaluated. We also determined if a change in anxiety from the start of treatment until just before oocyte retrieval affects the pregnancy rate. The predictive value of distress was assessed while controlling for several factors in subfertility treatment. RESULTS: Neither baseline nor procedural anxiety, nor depression affected the ongoing pregnancy rates, with odds ratios (ORs) of 1.04 (95% CI 0.82-1.33), 0.96 (95% CI 0.77-1.20) and 0.85 (95% CI 0.65-1.10), respectively. Neither did the anxiety gain score affect the pregnancy rate, OR 1.08 (95% CI 0.83-1.41). A cancellation of treatment could not be predicted by either anxiety or depression, OR 1.16 (95% CI 0.83-1.63) and 0.85 (95% CI 0.59-1.22), respectively. CONCLUSIONS: Inductees in IVF treatment can be reassured that anxiety and depression levels before and during treatment have no significant influence on the cancellation and pregnancy rates.

Stimulation of the ovaries in women with breast cancer undergoing fertility preservation: Alternative versus standard stimulation protocols; the study protocol of the STIM-trial.

BACKGROUND: Chemotherapy for breast cancer may have a negative impact on reproductive function due to gonadotoxicity. Fertility preservation via banking of oocytes or embryos after ovarian stimulation with FSH can increase the likelihood of a future live birth. It has been hypothesized that elevated serum estrogen levels during ovarian stimulation may induce breast tumour growth. This has led to the use of alternative stimulation protocols with addition of tamoxifen or letrozole. The effectiveness of these stimulation protocols in terms of oocyte yield is unknown. METHODS/DESIGN: Randomized open-label trial comparing ovarian stimulation plus tamoxifen and ovarian stimulation plus letrozole with standard ovarian stimulation in the course of fertility preservation. The study population consists of women with breast cancer who opt for banking of oocytes or embryos, aged 18-43years at randomisation. Primary outcome is the number of oocytes retrieved at follicle aspiration. Secondary outcomes are number of mature oocytes retrieved, number of oocytes or embryos banked and peak E2 levels during ovarian stimulation. DISCUSSION: Concerning the lack of evidence on which stimulation protocol should be used in women with breast cancer and the growing demand for fertility preservation, there is an urgent need to undertake this study. By performing this study, we will be able to closely monitor the effects of various stimulation protocols in women with breast cancer and pave the way for long term follow up on the safety of this procedure in terms of breast cancer prognosis.

Prevention of multiple pregnancies in couples with unexplained or mild male subfertility: randomised controlled trial of in vitro fertilisation with single embryo transfer or in vitro fertilisation in modified natural cycle compared with intrauterine insemination with controlled ovarian hyperstimulation.

OBJECTIVES: To compare the effectiveness of in vitro fertilisation with single embryo transfer or in vitro fertilisation in a modified natural cycle with that of intrauterine insemination with controlled ovarian hyperstimulation in terms of a healthy child. DESIGN: Multicentre, open label, three arm, parallel group, randomised controlled non-inferiority trial. SETTING: 17 centres in the Netherlands. PARTICIPANTS: Couples seeking fertility treatment after at least 12 months of unprotected intercourse, with the female partner aged between 18 and 38 years, an unfavourable prognosis for natural conception, and a diagnosis of unexplained or mild male subfertility. INTERVENTIONS: Three cycles of in vitro fertilisation with single embryo transfer (plus subsequent cryocycles), six cycles of in vitro fertilisation in a modified natural cycle, or six cycles of intrauterine insemination with ovarian hyperstimulation within 12 months after randomisation. MAIN OUTCOME MEASURES: The primary outcome was birth of a healthy child resulting from a singleton pregnancy conceived within 12 months after randomisation. Secondary outcomes were live birth, clinical pregnancy, ongoing pregnancy, multiple pregnancy, time to pregnancy, complications of pregnancy, and neonatal morbidity and mortality RESULTS: 602 couples were randomly assigned between January 2009 and February 2012; 201 were allocated to in vitro fertilisation with single embryo transfer, 194 to in vitro fertilisation in a modified natural cycle, and 207 to intrauterine insemination with controlled ovarian hyperstimulation. Birth of a healthy child occurred in 104 (52%) couples in the in vitro fertilisation with single embryo transfer group, 83 (43%) in the in vitro fertilisation in a modified natural cycle group, and 97 (47%) in the intrauterine insemination with controlled ovarian hyperstimulation group. This corresponds to a risk, relative to intrauterine insemination with ovarian hyperstimulation, of 1.10 (95% confidence interval 0.91 to 1.34) for in vitro fertilisation with single embryo transfer and 0.91 (0.73 to 1.14) for in vitro fertilisation in a modified natural cycle. These 95% confidence intervals do not extend below the predefined threshold of 0.69 for inferiority. Multiple pregnancy rates per ongoing pregnancy were 6% (7/121) after in vitro fertilisation with single embryo transfer, 5% (5/102) after in vitro fertilisation in a modified natural cycle, and 7% (8/119) after intrauterine insemination with ovarian hyperstimulation (one sided P=0.52 for in vitro fertilisation with single embryo transfer compared with intrauterine insemination with ovarian hyperstimulation; one sided P=0.33 for in vitro fertilisation in a modified natural cycle compared with intrauterine insemination with controlled ovarian hyperstimulation). CONCLUSIONS: In vitro fertilisation with single embryo transfer and in vitro fertilisation in a modified natural cycle were non-inferior to intrauterine insemination with controlled ovarian hyperstimulation in terms of the birth of a healthy child and showed comparable, low multiple pregnancy rates.Trial registration Current Controlled Trials ISRCTN52843371; Nederlands Trial Register NTR939.

Stress and marital satisfaction among women before and after their first cycle of in vitro fertilization and intracytoplasmic sperm injection.

OBJECTIVE: To determine differences in emotional status (anxiety and depression) and marital satisfaction in pregnant and nonpregnant women before and after their first cycle of IVF and intracytoplasmic sperm injection (ICSI). DESIGN: Repeated measurement. SETTING: Fertility department at a university and a regional hospital. PATIENT(S): Women entering their first treatment cycle of IVF or ICSI. INTERVENTION(S): Questionnaires on psychological factors were administered 3 to 12 days before the start of their first treatment cycle and repeated 3 weeks after the pregnancy test. MAIN OUTCOME MEASURE(S): State anxiety, depression, mood, and marital satisfaction. RESULT(S): At pretreatment, the women who became pregnant showed lower levels of depression than those who did not. Higher levels of depression in the pregnant women after the first cycle were due to higher scores on vital aspects of depression, related to signs of early pregnancy. Higher levels of depression in the nonpregnant women were due to a higher score on cognitive aspects of depression. CONCLUSION(S): Differences in emotional status between pregnant and nonpregnant women were present before treatment and became more apparent after the first IVF and ICSI cycle. There were no differences in emotional status between the women who underwent IVF and those who underwent ICSI.

[The emotional burden of artificial insemination: increased anxiety and depression following an unsuccessful treatment]. / De emotionele belasting van kunstmatige voortplanting: meer angst en depressie na een mislukte eerste behandeling.

OBJECTIVE: Determination of the emotional burden of the first IVF or ICSI treatment cycle, the effect of the treatment on the marital relationship, and the course of the treatment following a failed and a successful first attempt. DESIGN: Descriptive longitudinal study with repeated measures before and after the first treatment cycle. METHOD: 240 women and 219 men filled in questionnaires both before and after the first treatment cycle in the area of anxiety, depression, and the marital relationship (as measured with the 'Spielberger state trait anxiety inventory' (STAI), the 'Beck depression inventory for primary care' (BDI-PC) and the 'Maudsley marital questionnaire' (MMQ), respectively), as well as their plans for further treatment. RESULTS: After a first failed treatment cycle, both women and men showed an increase in depression, while women also showed increased anxiety. No differences were found between pre- and post-treatment levels of anxiety and depression after a successful treatment. After the first failed cycle, almost 13% of the women showed clinically relevant forms of depression. There was an increase in dissatisfaction with the sexual relationship in both men and women regardless of the success of the treatment. Before the start of the first treatment cycle, 2% of the couples had no intention to undergo further treatment if the first cycle failed; none of these couples started a new cycle. Ultimately, 18% of the couples refrained from further treatment following a failed first treatment cycle. CONCLUSION: After a failed first treatment cycle the couples showed an increase in depression and one in eight women had a clinically relevant form of depression. More than one out of every 6 couples decided to refrain from further treatment after a failed first cycle.

Laparoscopic subtotal hysterectomy versus laparoscopic total hysterectomy: a decade of experience.

At present, there are only few data on the surgical outcomes of laparoscopic hysterectomy (LH). Up till now, it has been unclear whether there is a difference in number of complications among the subcategories of laparoscopic total hysterectomy and laparoscopic subtotal hysterectomy (LSH). Therefore, we have performed a retrospective analysis to evaluate the peri- and postoperative outcomes in women undergoing LSH versus LH. This multi-centre retrospective cohort study (Canadian Task Force classification II-2) was conducted in multi-centres (two teaching hospitals and one university medical centre) in the Netherlands, all experienced in minimally invasive gynaecology. In a multi-centre retrospective cohort study we compared the long-term outcomes of laparoscopic subtotal hysterectomy and laparoscopic total hysterectomy (including laparoscopic assisted vaginal hysterectomy, laparoscopic hysterectomy and total laparoscopic hysterectomy). All laparoscopic hysterectomies from the last 10 years (January 1998 till December 2007) were included. Patient characteristics, intra- and postoperative complications, operating time and duration of hospital stay were recorded. The minimum follow-up was 6 months. A total of 390 cases of laparoscopic hysterectomies were included in the analysis: 192 laparoscopic subtotal hysterectomies and 198 laparoscopic total hysterectomies. Patient characteristics such as age and parity were equal in the groups. The overall number of short-term and long-term complications was comparable in both groups: 17% and 15%. Short-term complications (bleeding, fever) were 3% in the LSH group and 12% in the LH group. Long-term complications were (tubal prolapse and cervical stump reoperations) 15% in the LSH group and 3% in the LH group. Laparoscopic subtotal hysterectomy as compared with the different types of laparoscopic total hysterectomy is associated with more long-term postoperative complications, whereas laparoscopic total hysterectomy is associated with more short-term complications.

Long-term psychological adjustment to IVF/ICSI treatment in women.

BACKGROUND: The aim of this study was to gain more insight into long-term psychological adjustment to IVF in women. METHODS: In a prospective cohort study, 298 women entering their first IVF treatment cycle (including ICSI) completed standardized psychological questionnaires before the start of the treatment, just after the last treatment cycle, and 6 months and 3-5 years after the last treatment cycle. The main outcome measures were state anxiety, depression and mode of adaptation to unsuccessful IVF. RESULTS: Anxiety and depression were found at follow-up to return to baseline levels following treatment not resulting in a live birth, after an initial increase during treatment. On the contrary, treatment resulting in a live birth was found to lead to a more positive long-term emotional status. Women who focused on new life goals as a mode of adaptation 3-5 years after IVF without a live birth showed lower levels of anxiety and depression compared with those who persisted in their attempts to get pregnant. CONCLUSIONS: Treatment that resulted in a live birth led to more positive emotional adjustment. In addition, most women who did not give birth to a child after treatment adjusted well psychologically. Positive adjustment was related to developing new life goals rather than persisting in attempts to get pregnant. Helping women to change life goals after abandoning treatment might have beneficial effects on the adaptation process.

Women's emotional adjustment to IVF: a systematic review of 25 years of research.

This review provides an overview of how women adjust emotionally to the various phases of IVF treatment in terms of anxiety, depression or general distress before, during and after different treatment cycles. A systematic scrutiny of the literature yielded 706 articles that paid attention to emotional aspects of IVF treatment of which 27 investigated the women's emotional adjustment with standardized measures in relation to norm or control groups. Most studies involved concurrent comparisons between women in different treatment phases and different types of control groups. The findings indicated that women starting IVF were only slightly different emotionally from the norm groups. Unsuccessful treatment raised the women's levels of negative emotions, which continued after consecutive unsuccessful cycles. In general, most women proved to adjust well to unsuccessful IVF, although a considerable group showed subclinical emotional problems. When IVF resulted in pregnancy, the negative emotions disappeared, indicating that treatment-induced stress is considerably related to threats of failure. The concurrent research reviewed, should now be underpinned by longitudinal studies to provide more information about women's long-term emotional adjustment to unsuccessful IVF and about indicators of risk factors for problematic emotional adjustment after unsuccessful treatment, to foster focused psychological support for women at risk.

A longitudinal, prospective study on emotional adjustment before, during and after consecutive fertility treatment cycles.

BACKGROUND: A longitudinal study into the course of the emotional response to IVF from pre-treatment to 6 months post-treatment and factors that contributed to that course. METHODS: A total of 148 IVF patients and 71 partners completed self-report questionnaires on anxiety, depression, personality characteristics, meaning of fertility problems, coping, marital relationship and social support at pre-treatment. Assessments of anxiety and depression were repeated immediately following the final treatment cycle and again 6 months later (follow-up). RESULTS: Women showed an increase of both anxiety and depression after unsuccessful treatment and a decrease after successful treatment. Men showed no change in anxiety and depression either after successful or after unsuccessful treatment. In the 6 months after unsuccessful treatment, women showed no recovery. At follow-up, >20% of the women showed subclinical forms of anxiety and/or depression. Personality characteristics, meaning of the fertility problems, and social support determined the course of the emotional response. CONCLUSIONS: Most women adjusted well to unsuccessful treatment, but at follow-up, a considerable proportion still showed substantial emotional problems. Personality characteristics, pre-treatment meaning of the fertility problems and social support have demonstrated the adjustment to unsuccessful IVF in women. This allows early identification of women at risk as well as tailored interventions.

Stress and outcome success in IVF: the role of self-reports and endocrine variables.

BACKGROUND: The aim of this study was to examine the associations between urinary levels of the stress hormones adrenaline, noradrenaline and cortisol during treatment with self reported stress, in order to investigate the mechanism for the previously observed negative association of anxiety and depression with the outcome of IVF/ICSI. METHODS: In a multicentre prospective cohort study, women entering their first cycle of IVF/ICSI treatment were asked to participate. From each participant nocturnal urine samples were collected; pre-treatment, before oocyte retrieval and before embryo-transfer (ET), to assess hormonal concentrations. Additionally, two questionnaires were administered before the start of the treatment to measure anxiety and depression. RESULTS: 168 women completed the questionnaires and collected at least two urine specimens. A significant positive correlation between urinary adrenaline concentrations at baseline and ET and the scores on depression at baseline were found. In women with successful treatment, lower concentrations of adrenaline at oocyte retrieval and lower concentrations of adrenaline and noradrenaline at ET, compared with unsuccessful women, were found. CONCLUSIONS: The significant positive association of adrenaline concentration with pregnancy and with depression suggested that this adrenal hormone could be one of the links in the complex relationship between psychosocial stress and outcome after IVF/ICSI.

External validation of the templeton model for predicting success after IVF.

This study aimed to externally validate the prognostic model presented by Templeton in 1996 for live births resulting from IVF treatment. Data were used from the University Hospital, Nijmegen, The Netherlands, from March 1991 to January 1999. The predictive capacity of the model in our population discriminated between those women with a low probability of success and those with a relatively high probability. Despite these encouraging findings, our data show that implementation of the model in clinical decision-making remains difficult. The Templeton model is not applicable or usable in daily clinical practice, because the model did not give more information about the prognosis for the vast majority of the patients. Therefore, the search for better prognostic factors resulting in better predictive models should continue.

The effect of anxiety and depression on the outcome of in-vitro fertilization.

BACKGROUND: The study aim was to clarify the role of anxiety and depression on the outcome in assisted reproductive treatment. Previous studies on this topic have shown contradicting results, which may have been caused by population characteristics, the design of the study, or small sample sizes. METHODS: In a multicentre prospective study, 291 out of 359 (81%) consecutively invited women agreed to participate. Before down-regulation by means of gonadotrophin-releasing hormone (GnRH) analogues in a long IVF protocol, patients were asked to complete the Dutch version of the State and Trait Anxiety Inventory to measure anxiety, and the Dutch version of the Beck Depression Inventory (BDI) to measure depression. Multiple logistic regression analysis was used to analyse known predictors of pregnancy and psychological factors and their relationship with treatment outcome. RESULTS: A significant relationship was shown between baseline psychological factors and the probability to become pregnant after IVF/intracytoplasmic sperm injection (ICSI) treatment, controlling for other factors. State anxiety had a slightly stronger correlation (P = 0.01) with treatment outcome than depression (P = 0.03). CONCLUSIONS: Pre-existing psychological factors are independently related to treatment outcome in IVF/ICSI, and should therefore be taken into account in patient counselling. Psychological factors may be improved by intervention, whereas demographic and gynaecological factors cannot. Future studies should be directed towards underlying mechanisms involved and the role of evidence-based distress reduction in order to improve treatment results.
