RESUMEN

STUDY QUESTION: Is a single endometrial scratch prior to the second fresh IVF/ICSI treatment cost-effective compared to no scratch, when evaluated over a 12-month follow-up period? SUMMARY ANSWER: The incremental cost-effectiveness ratio (ICER) for an endometrial scratch was €6524 per additional live birth, but due to uncertainty regarding the increase in live birth rate this has to be interpreted with caution. WHAT IS KNOWN ALREADY: Endometrial scratching is thought to improve the chances of success in couples with previously failed embryo implantation in IVF/ICSI treatment. It has been widely implemented in daily practice, despite the lack of conclusive evidence of its effectiveness and without investigating whether scratching allows for a cost-effective method to reduce the number of IVF/ICSI cycles needed to achieve a live birth. STUDY DESIGN, SIZE, DURATION: This economic evaluation is based on a multicentre randomized controlled trial carried out in the Netherlands (SCRaTCH trial) that compared a single scratch prior to the second IVF/ICSI treatment with no scratch in couples with a failed full first IVF/ICSI cycle. Follow-up was 12 months after randomization.Economic evaluation was performed from a healthcare and societal perspective by taking both direct medical costs and lost productivity costs into account. It was performed for the primary outcome of biochemical pregnancy leading to live birth after 12 months of follow-up as well as the secondary outcome of live birth after the second fresh IVF/ICSI treatment (i.e. the first after randomization). To allow for worldwide interpretation of the data, cost level scenario analysis and sensitivity analysis was performed. PARTICIPANTS/MATERIALS, SETTING, METHODS: From January 2016 until July 2018, 933 women with a failed first IVF/ICSI cycle were included in the trial. Data on treatment and pregnancy were recorded up until 12 months after randomization, and the resulting live birth outcomes (even if after 12 months) were also recorded.Total costs were calculated for the second fresh IVF/ICSI treatment and for the full 12 month period for each participant. We included costs of all treatments, medication, complications and lost productivity costs. Cost-effectiveness analysis was carried out by calculating ICERs for scratch compared to control. Bootstrap resampling was used to estimate the uncertainty around cost and effect differences and ICERs. In the sensitivity and scenario analyses, various unit costs for a single scratch were introduced, amongst them, unit costs as they apply for the United Kingdom (UK). MAIN RESULTS AND THE ROLE OF CHANCE: More live births occurred in the scratch group, but this also came with increased costs over a 12-month period. The estimated chance of a live birth after 12 months of follow-up was 44.1% in the scratch group compared to 39.3% in the control group (risk difference 4.8%, 95% CI -1.6% to +11.2%). The mean costs were on average €283 (95% CI: -€299 to €810) higher in the scratch group so that the point average ICER was €5846 per additional live birth. The ICER estimate was surrounded with a high level of uncertainty, as indicated by the fact that the cost-effectiveness acceptability curve (CEAC) showed that there is an 80% chance that endometrial scratching is cost-effective if society is willing to pay ∼€17 500 for each additional live birth. LIMITATIONS, REASONS FOR CAUTION: There was a high uncertainty surrounding the effects, mainly in the clinical effect, i.e. the difference in the chance of live birth, which meant that a single straightforward conclusion could not be ascertained as for now. WIDER IMPLICATIONS OF THE FINDINGS: This is the first formal cost-effectiveness analysis of endometrial scratching in women undergoing IVF/ICSI treatment. The results presented in this manuscript cannot provide a clear-cut expenditure for one additional birth, but they do allow for estimating costs per additional live birth in different scenarios once the clinical effectiveness of scratching is known. As the SCRaTCH trial was the only trial with a follow-up of 12 months, it allows for the most complete estimation of costs to date.

RESUMEN

STUDY QUESTION: Does endometrial scratching in women with one failed IVF/ICSI treatment affect the chance of a live birth of the subsequent fresh IVF/ICSI cycle? SUMMARY ANSWER: In this study, 4.6% more live births were observed in the scratch group, with a likely certainty range between -0.7% and +9.9%. WHAT IS KNOWN ALREADY: Since the first suggestion that endometrial scratching might improve embryo implantation during IVF/ICSI, many clinical trials have been conducted. However, due to limitations in sample size and study quality, it remains unclear whether endometrial scratching improves IVF/ICSI outcomes. STUDY DESIGN, SIZE, DURATION: The SCRaTCH trial was a non-blinded randomised controlled trial in women with one unsuccessful IVF/ICSI cycle and assessed whether a single endometrial scratch using an endometrial biopsy catheter would lead to a higher live birth rate after the subsequent IVF/ICSI treatment compared to no scratch. The study took place in 8 academic and 24 general hospitals. Participants were randomised between January 2016 and July 2018 by a web-based randomisation programme. Secondary outcomes included cumulative 12-month ongoing pregnancy leading to live birth rate. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women with one previous failed IVF/ICSI treatment and planning a second fresh IVF/ICSI treatment were eligible. In total, 933 participants out of 1065 eligibles were included (participation rate 88%). MAIN RESULTS AND THE ROLE OF CHANCE: After the fresh transfer, 4.6% more live births were observed in the scratch compared to control group (110/465 versus 88/461, respectively, risk ratio (RR) 1.24 [95% CI 0.96-1.59]). These data are consistent with a true difference of between -0.7% and +9.9% (95% CI), indicating that while the largest proportion of the 95% CI is positive, scratching could have no or even a small negative effect. Biochemical pregnancy loss and miscarriage rate did not differ between the two groups: in the scratch group 27/153 biochemical pregnancy losses and 14/126 miscarriages occurred, while this was 19/130 and 17/111 for the control group (RR 1.21 (95% CI 0.71-2.07) and RR 0.73 (95% CI 0.38-1.40), respectively). After 12 months of follow-up, 5.1% more live births were observed in the scratch group (202/467 versus 178/466), of which the true difference most likely lies between -1.2% and +11.4% (95% CI). LIMITATIONS, REASONS FOR CAUTION: This study was not blinded. Knowledge of allocation may have been an incentive for participants allocated to the scratch group to continue treatment in situations where they may otherwise have cancelled or stopped. In addition, this study was powered to detect a difference in live birth rate of 9%. WIDER IMPLICATIONS OF THE FINDINGS: The results of this study are an incentive for further assessment of the efficacy and clinical implications of endometrial scratching. If a true effect exists, it may be smaller than previously anticipated or may be limited to specific groups of women undergoing IVF/ICSI. Studying this will require larger sample sizes, which will be provided by the ongoing international individual participant data-analysis (PROSPERO CRD42017079120). At present, endometrial scratching should not be performed outside of clinical trials.

RESUMEN

STUDY QUESTION: Are six cycles of ovulation induction with gonadotrophins more cost-effective than six cycles of ovulation induction with clomiphene citrate (CC) with or without IUI in normogonadotropic anovulatory women not pregnant after six ovulatory cycles with CC? SUMMARY ANSWER: Both gonadotrophins and IUI are more expensive when compared with CC and intercourse, and gonadotrophins are more effective than CC. WHAT IS KNOWN ALREADY: In women with normogonadotropic anovulation who ovulate but do not conceive after six cycles with CC, medication is usually switched to gonadotrophins, with or without IUI. The cost-effectiveness of these changes in policy is unknown. STUDY DESIGN, SIZE, DURATION: We performed an economic evaluation of ovulation induction with gonadotrophins compared with CC with or without IUI in a two-by-two factorial multicentre randomized controlled trial in normogonadotropic anovulatory women not pregnant after six ovulatory cycles with CC. Between December 2008 and December 2015 women were allocated to six cycles with gonadotrophins plus IUI, six cycles with gonadotrophins plus intercourse, six cycles with CC plus IUI or six cycles with CC plus intercourse. The primary outcome was conception leading to a live birth achieved within 8 months of randomization. PARTICIPANTS/MATERIALS, SETTING, METHODS: We performed a cost-effectiveness analysis on direct medical costs. We calculated the direct medical costs of ovulation induction with gonadotrophins versus CC and of IUI versus intercourse in six subsequent cycles. We included costs of medication, cycle monitoring, interventions, and pregnancy leading to live birth. Resource use was collected from the case report forms and unit costs were derived from various sources. We calculated incremental cost-effectiveness ratios (ICER) for gonadotrophins compared to CC and for IUI compared to intercourse. We used non-parametric bootstrap resampling to investigate the effect of uncertainty in our estimates. The analysis was performed according to the intention-to-treat principle. MAIN RESULTS AND THE ROLE OF CHANCE: We allocated 666 women in total to gonadotrophins and IUI (n = 166), gonadotrophins and intercourse (n = 165), CC and IUI (n = 163), or CC and intercourse (n = 172). Mean direct medical costs per woman receiving gonadotrophins or CC were €4495 versus €3006 (cost difference of €1475 (95% CI: €1457-€1493)). Live birth rates were 52% in women allocated to gonadotrophins and 41% in those allocated to CC (relative risk (RR) 1.24:95% CI: 1.05-1.46). The ICER was €15 258 (95% CI: €8721 to €63 654) per additional live birth with gonadotrophins. Mean direct medical costs per woman allocated to IUI or intercourse were €4497 versus €3005 (cost difference of €1510 (95% CI: €1492-€1529)). Live birth rates were 49% in women allocated to IUI and 43% in those allocated to intercourse (RR = 1.14:95% CI: 0.97-1.35). The ICER was €24 361 (95% CI: €-11 290 to €85 172) per additional live birth with IUI. LIMITATIONS, REASONS FOR CAUTION: We allowed participating hospitals to use their local protocols for ovulation induction and IUI, which may have led to variation in costs, but which increases generalizability. Indirect costs generated by transportation or productivity loss were not included. We did not evaluate letrozole, which is potentially more effective than CC. WIDER IMPLICATIONS OF THE FINDINGS: Gonadotrophins are more effective, but more expensive than CC, therefore, the use of gonadotrophins in women with normogonadotropic anovulation who have not conceived after six ovulatory CC cycles depends on society's willingness to pay for an additional child. In view of the uncertainty around the cost-effectiveness estimate of IUI, these data are not sufficient to make recommendations on the use of IUI in these women. In countries where ovulation induction regimens are reimbursed, policy makers and health care professionals may use our results in their guidelines.

RESUMEN

STUDY QUESTION: Is FSH or clomiphene citrate (CC) the most effective stimulation regimen in terms of ongoing pregnancies in couples with unexplained subfertility undergoing IUI with adherence to strict cancellation criteria as a measure to reduce the number of multiple pregnancies? SUMMARY ANSWER: In IUI with adherence to strict cancellation criteria, ovarian stimulation with FSH is not superior to CC in terms of the cumulative ongoing pregnancy rate, and yields a similar, low multiple pregnancy rate. WHAT IS ALREADY KNOWN: FSH has been shown to result in higher pregnancy rates compared to CC, but at the cost of high multiple pregnancy rates. To reduce the risk of multiple pregnancy, new ovarian stimulation regimens have been suggested, these include strict cancellation criteria to limit the number of dominant follicles per cycle i.e. withholding insemination when more than three dominant follicles develop. With such a strategy, it is unclear whether the ovarian stimulation should be done with FSH or with CC. STUDY DESIGN, SIZE, DURATION: We performed an open-label multicenter randomized superiority controlled trial in the Netherlands (NTR 4057). PARTICIPANTS/MATERIALS, SETTING, METHODS: We randomized couples diagnosed with unexplained subfertility and scheduled for a maximum of four cycles of IUI with ovarian stimulation with 75 IU FSH or 100 mg CC. Cycles were cancelled when more then three dominant follicles developed. The primary outcome was cumulative ongoing pregnancy rate. Multiple pregnancy was a secondary outcome. We analysed the data on intention to treat basis. We calculated relative risks and absolute risk difference with 95% CI. MAIN RESULTS AND THE ROLE OF CHANCE: Between July 2013 and March 2016, we allocated 369 women to ovarian stimulation with FSH and 369 women to ovarian stimulation with CC. A total of 113 women (31%) had an ongoing pregnancy following ovarian stimulation with FSH and 97 women (26%) had an ongoing pregnancy following ovarian stimulation with CC (RR = 1.16, 95% CI: 0.93-1.47, ARD = 0.04, 95% CI: -0.02 to 0.11). Five women (1.4%) had a multiple pregnancy following ovarian stimulation with FSH and eight women (2.2%) had a multiple pregnancy following ovarian stimulation with CC (RR = 0.63, 95% CI: 0.21-1.89, ARD = -0.01, 95% CI: -0.03 to 0.01). LIMITATIONS, REASONS FOR CAUTION: We were not able to blind this study due to the nature of the interventions. We consider it unlikely that this has introduced performance bias, since pregnancy outcomes are objective outcome measures. WIDER IMPLICATIONS OF THE FINDINGS: We revealed that adherence to strict cancellation criteria is a successful solution to reduce the number of multiple pregnancies in IUI. To decide whether ovarian stimulation with FSH or with CC should be the regimen of choice, costs and patients' preferences should be taken into account.

RESUMEN

BACKGROUND: Success rates of assisted reproductive techniques (ART) are approximately 30%, with the most important limiting factor being embryo implantation. Mechanical endometrial injury, also called 'scratching', has been proposed to positively affect the chance of implantation after embryo transfer, but the currently available evidence is not yet conclusive. The primary aim of this study is to determine the effect of endometrial scratching prior to a second fresh in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycle on live birth rates in women with a failed first IVF/ICSI cycle. METHOD: Multicenter randomized controlled trial in Dutch academic and non-academic hospitals. A total of 900 women will be included of whom half will undergo an endometrial scratch in the luteal phase of the cycle prior to controlled ovarian hyperstimulation using an endometrial biopsy catheter. The primary endpoint is the live birth rate after the 2nd fresh IVF/ICSI cycle. Secondary endpoints are costs, cumulative live birth rate (after the full 2nd IVF/ICSI cycle and over 12 months of follow-up); clinical and ongoing pregnancy rate; multiple pregnancy rate; miscarriage rate and endometrial tissue parameters associated with implantation failure. DISCUSSION: Multiple studies have been performed to investigate the effect of endometrial scratching on live birth rates in women undergoing IVF/ICSI cycles. Due to heterogeneity in both the method and population being scratched, it remains unclear which group of women will benefit from the procedure. The SCRaTCH trial proposed here aims to investigate the effect of endometrial scratching prior to controlled ovarian hyperstimulation in a large group of women undergoing a second IVF/ICSI cycle.

RESUMEN

OBJECTIVE: To study the effectiveness of four cycles of intrauterine insemination (IUI) with ovarian stimulation (OS) by follicle-stimulating hormone (FSH) or by clomiphene citrate (CC), and adherence to strict cancellation criteria. SETTING: Randomised controlled trial among 22 secondary and tertiary fertility clinics in the Netherlands. PARTICIPANTS: 732 women from couples diagnosed with unexplained or mild male subfertility and an unfavourable prognosis according to the model of Hunault of natural conception. INTERVENTIONS: Four cycles of IUI-OS within a time horizon of 6 months comparing FSH 75 IU with CC 100 mg. The primary outcome is ongoing pregnancy conceived within 6 months after randomisation, defined as a positive heartbeat at 12 weeks of gestation. Secondary outcomes are cancellation rates, number of cycles with a monofollicular or with multifollicular growth, number of follicles >14 mm at the time of ovulation triggering, time to ongoing pregnancy, clinical pregnancy, miscarriage, live birth and multiple pregnancy. We will also assess if biomarkers such as female age, body mass index, smoking status, antral follicle count and endometrial aspect and thickness can be used as treatment selection markers. ETHICS AND DISSEMINATION: The study has been approved by the Medical Ethical Committee of the Academic Medical Centre and from the Dutch Central Committee on Research involving Human Subjects (CCMO NL 43131-018-13). Results will be disseminated through peer-reviewed publications and presentations at international scientific meetings. TRIAL REGISTRATION NUMBER: NTR4057.

RESUMEN

STUDY QUESTION: Is curettage more effective than expectant management in case of an incomplete evacuation after misoprostol treatment for first trimester miscarriage? SUMMARY ANSWER: Curettage leads to a higher chance of complete evacuation but expectant management is successful in at least 76% of women with an incomplete evacuation of the uterus after misoprostol treatment for first trimester miscarriage. WHAT IS KNOWN ALREADY: In 5-50% of the women treated with misoprostol, there is a suspicion of incomplete evacuation of the uterus on sonography. Although these women generally have minor symptoms, such a finding often leads to additional curettage. STUDY DESIGN, SIZE, DURATION: From June 2012 until July 2014, we conducted a nationwide multicenter randomized controlled trial (RCT). Women who had had primary misoprostol treatment for miscarriage with sonographic evidence of incomplete evacuation of the uterus were randomly allocated to either curettage or expectant management (1:1), using a web-based application. PARTICIPANTS/MATERIALS, SETTING, METHODS: We included 59 women in 27 hospitals; 30 were allocated to curettage and 29 were allocated to expectant management. A successful outcome was defined as sonographic finding of an empty uterus 6 weeks after randomization. MAIN RESULTS AND THE ROLE OF CHANCE: Baseline characteristics of both groups were comparable. Empty uterus on sonography or uneventful clinical follow-up was seen in 29/30 women (97%) allocated to curettage compared with 22/29 women (76%) allocated to expectant management (RR 1.3, 95% CI 1.03-1.6) with complication rates of 10% versus 10%, respectively (RR 0.97, 95% CI 0.21-4.4). In the group allocated to curettage, no woman required re-curettage, while two women (6.7%) underwent hysteroscopy (for other or unknown reasons). In the women allocated to expectant management, curettage was performed in four women (13.8%) and three women (10.3%) underwent hysteroscopy. LIMITATIONS, REASONS FOR CAUTION: Due to a strong patient preference, mainly for expectant management, the targeted sample size could not be included and the trial was stopped prematurely. WIDER IMPLICATIONS OF THE FINDINGS: In women suspected of incomplete evacuation of the uterus after misoprostol, curettage is more effective than expectant management. However, expectant management is equally safe and prevents curettage for most of the women. This finding could further restrain the use of curettage in the treatment of first trimester miscarriage. STUDY FUNDING/COMPETING INTERESTS: This study was funded by ZonMw, a Dutch organization for Health Research and Development, project number 80-82310-97-12066. There were no conflicts of interests.

RESUMEN

BACKGROUND: A caesarean section (CS) can cause a defect or disruption of the myometrium at the site of the uterine scar, called a niche. In recent years, an association between a niche and postmenstrual spotting after a CS has been demonstrated. Hysteroscopic resection of these niches is thought to reduce spotting and menstrual pain. However, there are no randomised trials assessing the effectiveness of a hysteroscopic niche resection. METHODS/DESIGN: We planned a multicentre randomised trial comparing hysteroscopic niche resection to no intervention. We study women with postmenstrual spotting after a CS and a niche with a residual myometrium of at least 3 mm during sonohysterography. After informed consent is obtained, eligible women will be randomly allocated to hysteroscopic resection of the niche or expectant management for 6 months. The primary outcome is the number of days with postmenstrual spotting during one menstrual cycle 6 months after randomisation. Secondary outcomes are menstrual characteristics, menstruation related pain and experienced discomfort due to spotting or menstrual pain, quality of life, patient satisfaction, sexual function, urological symptoms, medical consultations, medication use, complications, lost productivity and medical costs. Measurements will be performed at baseline and at 3 and 6 months after randomisation. A cost-effectiveness analysis will be performed from a societal perspective at 6 months after randomisation. DISCUSSION: This trial will provide insight in the (cost)effectiveness of hysteroscopic resection of a niche versus expectant management in women who have postmenstrual spotting and a niche with sufficient residual myometrium to perform a hysteroscopic niche resection.

RESUMEN

In a descriptive retrospective cohort study, we determined the cumulative pregnancy rate for couples undergoing intra-uterine insemination (IUI) with at least one total motile sperm count (TMC) <1 million compared to couples with a TMC consistently >1 million. Eight hundred and ninety-five cycles in 273 couples were studied from 2006 to 2009. In 895 cycles, ovarian stimulation was performed through recFSH injections. IUI was scheduled 38 ± 2 h after the administration of HCG when at least one follicle measured >18 mm. The cumulative pregnancy rate according to the TMC was calculated. The cumulative pregnancy rate after four cycles of IUI was 17.3% in couples with at least one TMC <1 million and 25.5% in couples with a TMC consistently >1 million. It is concluded that the TMC does not significantly influence cumulative pregnancy rates after 4 IUI cycles. Couples with a low TMC could benefit from IUI. This could be considered before IVF.

RESUMEN

BACKGROUND: On the question of how to counsel adolescents with irregular menstrual cycles or oligomenorrhoea, no clear answer has been given. Adolescents with oligomenorrhoea especially show endocrine abnormalities and may be at risk for ovulatory dysfunction and the polycystic ovary syndrome in adulthood. METHODS: We followed a cohort of adolescents to document changes in menstrual cycle pattern between ages 15 and 18 years in the general population. RESULTS: Two per cent (2/128) of adolescents with regular menstrual cycles developed oligomenorrhoea, and 12% (17/148) of those with irregular menstrual cycles did so. Fifty-one per cent (34/67) of the oligomenorrhoeic adolescents remained oligomenorrhoeic. Increase in body mass index (BMI), concentration of LH, androstenedione or testosterone, and polycystic ovaries (PCO) were associated with persistence of oligomenorrhoea. In multivariate analysis only a normal to high BMI (>19.6 kg/m(2)) consistently contributed significantly to predict persistent oligomenorrhoea. Glucose:insulin ratio as a marker for insulin resistance was not associated with an increased risk for oligomenorrhoea. CONCLUSIONS: Oligomenorrhoea at age 18 years is better predicted by menstrual cycle pattern at age 15 years than by LH or androgen concentrations or PCO at this age. Not only obese, but also normal weight oligomenorrhoeic, adolescents have a high risk of remaining oligomenorrhoeic.

RESUMEN

BACKGROUND: Previous studies suggest that elevated basal FSH concentrations are related to aneuploid pregnancies. However, there have been no prospective studies evaluating the incidence of aneuploidies in relation to basal FSH concentrations. Since the majority of aneuploid conceptions end in early pregnancy loss or abortion of a recognized pregnancy, these determinants are appropriate intermediate end-points to study aneuploidy. METHODS: We performed a prospective study in 129 women without a history of subfertility pursuing a spontaneous pregnancy. Basal FSH concentrations were measured during three menstrual cycles. Urinary HCG levels were measured during menstruation for a maximum of six menstrual cycles, to detect early pregnancy loss. We estimated the effect of basal FSH concentrations on pregnancy outcome, taking into account possible confounders. RESULTS: We observed no significant effect of basal FSH concentrations on the incidence of early pregnancy loss or abortion of clinically recognized pregnancies. CONCLUSIONS: We conclude that in a population of women without a history of subfertility, pursuing a spontaneous pregnancy, basal FSH concentrations are not related to the incidence of early pregnancy loss or abortions. This prospective study therefore fails to confirm a relationship between signs of decreased ovarian reserve and aneuploid pregnancies.

RESUMEN

To ascertain the effectiveness and feasibility of testing for microalbuminuria and the albumin/creatinine ratio as an early indication of hypertensive disorders of pregnancy, we measured albumin and creatinine excretion in 95 healthy pregnant women between 16 and 20 weeks of pregnancy. Nine women developed hypertensive complications; one of them became pre-eclamptic. There were no statistically significant differences in urine albumin and creatinine concentrations nor in the albumin/creatinine ratio between those women who developed pregnancy-induced hypertension and those who did not. Microalbuminuria testing had a specificity of 0.95 (95% CI: 0.88 - 0.99) and a sensitivity of 0.11 (95% CI: 0.03 - 0.48). The albumin/creatinine ratio had a specificity of 0.98 (95% CI: 0.92 - 1.0) and a sensitivity of 0.22 (95% CI: 0.03 - 0.6). The albumin/creatinine ratio was significantly lower in women who delivered prematurely. We conclude that mid-trimester testing for microalbuminuria and the measurement of the urinary albumin/creatinine ratio are not effective tools for the early recognition of pregnancy-induced hypertension in healthy pregnant women.

RESUMEN

BACKGROUND: Two recent studies reported elevated basal FSH concentrations in women with a history of aneuploid conceptions. However, it is not known whether these elevated basal FSH concentrations reflect depletion of the primordial follicle pool, or were caused by an increased secretory drive for FSH. METHODS: Inhibin B and estradiol concentrations were measured as indicators for depletion of the primordial follicle pool in women with a history of a Down's syndrome pregnancy and in controls. RESULTS: In the women with a history of a Down's syndrome pregnancy, there was a significant inverse correlation between basal FSH and inhibin B concentrations (P < 0.0001, 95% CI -0.26 to -0.56). In the control group, this correlation did not reach statistical significance. CONCLUSIONS: Our data indicate that the elevated basal FSH concentrations observed in women with a history of a Down's syndrome pregnancy are likely to reflect early depletion of the primordial follicle pool. Therefore, further research into the ovarian ageing process could provide more insight in the origination of chromosomal abnormalities during pregnancy.

RESUMEN

Recent publications have reported a relation between a decreased ovarian reserve and Down's syndrome pregnancies. Using the data of a case-control study into risk factors for a Down's syndrome pregnancy, we estimated the usefulness of pre-conceptional basal follicle stimulating hormone (FSH) screening (detection rate, false positive rate, positive and negative likelihood ratio, as well as the loss rate of unaffected pregnancies) to identify Down's syndrome pregnancies. The optimal detection rate of pre-conceptional basal FSH screening for Down's syndrome pregnancies was 14%, corresponding to a false positive rate of 5% and a positive likelihood ratio of 2.8. Incorporation of basal FSH screening into the regimen of first trimester serum screening followed by nuchal translucency measurement would increase the detection rate from 85 to 87%. However, basal FSH screening alone or in combination with other screening methods would cause an unacceptably high loss rate of unaffected pregnancies compared with current screening protocols, indicating that routine pre-conception basal FSH screening would not be useful to identify women at risk for a Down's syndrome pregnancy. However, when elevated basal FSH concentrations are diagnosed during subfertility evaluation, an elevated risk for a Down's syndrome pregnancy could be discussed with women who become pregnant.

RESUMEN

STUDY OBJECTIVE: To evaluate the possible role of inappropriate LH secretion, hyperandrogenism, and hyperinsulinemia in the development of polycystic ovaries (PCO) and the polycystic ovary syndrome. DESIGN: Observational. SETTING: General population samples. PARTICIPANTS: 58 adolescents with regular menstrual cycles, 50 with irregular menstrual cycles, and 29 with oligomenorrhea (age 16.7+/-0.9 years). INTERVENTIONS: Transabdominal pelvic ultrasonography and vena puncture. MAIN OUTCOME MEASURES: PCO; LH, androstenedione, and testosterone levels; overnight fasting insulin concentrations; and oligomenorrhea. RESULTS: The prevalence of PCO increased significantly with the irregularity of the menstrual cycle pattern, as illustrated by the study, finding PCO in 9% of the girls with regular menstrual cycles, 28% of those with irregular menstrual cycles, and 45% of oligomenorrheic girls. The LH and androgen concentrations were significantly higher in girls with PCO; the insulin levels and the glucose-insulin ratio did not differ when the girls with PCO were compared with girls with normal ovaries. Oligomenorrheic girls with PCO had the highest androgen and LH concentrations; their insulin concentrations and glucose-insulin ratio were in the same range as girls with regular menstrual cycles and normal ovaries; and both their hip and waist girths were wider, although their waist-hip ratio was normal. CONCLUSIONS: PCO in adolescents is associated with irregular menstrual cycles, oligomenorrhea, and/or high androgen and LH levels; but no relationship was found with the insulin level or glucose-insulin ratio. Thus, it is doubtful that hyperinsulinemia is an important factor in the development of PCO or polycystic ovary syndrome.

RESUMEN

OBJECTIVE: To assess the predictive value of elevated basal FSH concentrations during the initial subfertility workup with respect to fecundity in a general subfertility population with ovulatory menstrual cycles. DESIGN: Nested case-control study. SETTING: Fertility center of a university hospital. PATIENT(S): Fifty subfertile women with basal FSH levels >10.0 IU/L and 50 age-matched controls. INTERVENTION(S): Long-term follow-up (3-7 years). MAIN OUTCOME MEASURE(S): Pregnancies, deliveries, and time to pregnancy. RESULT(S): Patients with elevated basal FSH levels and controls were comparable with regard to basic characteristics, clinical diagnoses, and subfertility treatment. Long-term follow-up showed that 52% of the women with elevated basal FSH concentrations became pregnant (positive predictive value 48%) versus 62% of the controls, and 42% versus 46% eventually delivered a child, respectively. The mean time to pregnancy was 3.0 years in the elevated-FSH group and 3.4 years in controls. Most of the pregnancies in both groups occurred after spontaneous conceptions. CONCLUSION(S): The results of this study suggest that screening for elevated basal FSH concentrations is of no additional value in a general subfertility population with ovulatory menstrual cycles.

RESUMEN

Data on changes in hormone concentrations during the first years after menarche are scarce. We studied the relation between gynecological age (age minus age at menarche), hormone concentrations, and body measurements from the lst to the 6th yr after menarche in 229 observations of girls with regular menstrual cycles, 157 observations of girls with irregular menstrual cycles, and 104 observations of girls with oligomenorrhea. Body Mass Index, waist circumference, hip circumference, LH, androstenedione, testosterone, and dehydro-epiandrosterone sulphate increased significantly (linear regression, P < 0.05) by gynecological age in all menstrual cycle pattern groups. For PRL and estradiol a significant increase with gynecological age was only documented in the regular menstrual cycle group and for waist to hip ratio only in the irregular menstrual cycle group. No significant correlation could be documented between gynecological age and overnight fasting insulin concentrations or glucose to insulin ratio. We found no significant correlation between insulin concentrations or glucose to insulin ratio and androgen concentrations. Significant positive correlations were found between LH and androgens. LH and androgen levels increase during the first years after menarche, and reference values should be adjusted for gynecological age. In these years, no significant correlation between hyperinsulinemia and hyperandrogenemia could be documented.

RESUMEN

Hospital based studies have shown that oligomenorrhoeic adolescents have high luteinizing hormone (LH) and androgen concentrations, endocrine signs of polycystic ovary syndrome (PCOS). The prevalence of these abnormalities in an unselected population of adolescents is not known. We determined LH, follicle stimulating hormone (FSH), androstenedione, testosterone, dehydroepiandrosterone sulphate (DHEAS), oestradiol and prolactin concentrations in unselected population samples of adolescents with oligomenorrhoea, secondary amenorrhoea and regular menstrual cycles. A total of 2248 white, west European adolescents, aged 15.3 +/- 0.6 (mean +/- SD) years, participated. Blood was taken from 107 adolescents with regular menstrual cycles, 52 with oligomenorrhoea and four with secondary amenorrhoea. Oligomenorrhoeic adolescents had higher mean LH, androstenedione, testosterone, DHEAS and oestradiol concentrations compared with girls with regular menstrual cycles; 57% of the oligomenorrhoeic girls had LH or androgen concentrations above the 95th centile of adolescents with regular menstrual cycles. None of the 52 oligomenorrhoeic girls and only one of four girls with secondary amenorrhoea had a hypogonadotrophic endocrine pattern. The present study and available literature support the view that oligomenorrhoea in adolescents is not a stage in the physiological maturation of the hypothalamic pituitary-ovarian axis but an early sign of PCOS associated with subfertility. Physicians should consider endocrine evaluation before reassuring oligomenorrhoeic girls or prescribing oral contraceptives to these girls.
