RESUMEN
Introduction: A reduction in anti-müllerian hormone (AMH) levels at short-term after bariatric surgery (BS) has been previously described. However, an assessment of ovarian reserve at longer-follow up, and a comprehensive evaluation of the potentially implicated factors has not been reported. Design: Prospective cohort study. Materials and methods: Twenty women aged 18-40 years with BMI 43.95 kg/m2 undergoing BS were studied at baseline (BS0), and at 1 month (BS1), 4 months (BS2), 12 months (BS3), and 24-36 months (BS4) after the surgery. Anthropometrics, reproductive hormones (AMH, FSH, LH, estradiol, testosterone, SHBG, androstenedione), metabolic parameters (adiponectin, leptin, ghrelin, insulin), and nutritional blood parameters (markers of nutritional status, vitamins, and minerals) were obtained at each study time point. Antral follicular count (AFC) was assessed by ultrasonography at BS0, BS3, and BS4. Mixed models were used for analysis of longitudinal data. Results: The mean AMH level was 3.88 ng/mL at BS0, decreased at BS3 (mean= 2.59 ng/mL; p=0.009), and remained stable between BS3 and BS4 (mean= 2.96 ng/mL; p=0.409). We also observed a non-significant decrease in AFC at BS3 (mean=26.14 at BS0, mean 16.81 at BS3; p=0.088) that remained stable at BS4 (mean= 17.86; p=0.731). Mixed models analysis showed: (a) a decrease in 10 kg of body weight was associated with an average decrease of 0.357 ng/mL in AMH (p=0.014); (b) a decrease in 1 BMI point was associated with an average decrease of 0.109 ng/mL in AMH (p=0.005); (c) an increase in 1 µg/mL of adiponectin was associated with an average decrease of 0.091 ng/ml in AMH (p=0.041) Significant positive correlations were found between the AMH levels after BS and plasma concentrations of testosterone, free androgen index, insulin and HOMA index. No significant correlations were detected between AMH levels and nutritional parameters. Conclusions: Our results were in line with previous observations, showing that AMH levels decreased significantly at 12 months after bariatric surgery, in parallel with a non-significant reduction in AFC. Both ovarian reserve markers showed a later stabilization up to the end of the study. Of note, postoperative AMH levels were positively correlated with key androgen and insulin resistance-related parameters.

PURPOSE: Currently, 15% of gynaecological and 9% of haematological malignancies are diagnosed before the age of 40. The increased survival rates of cancer patients who are candidates for gonadotoxic treatments, the delay in childbearing to older ages, and the optimization of in vitro fertilisation techniques have all contributed to an increased interest in fertility preservation (FP) treatments. This study reviews the experience of the Fertility Preservation Programme (FPP) of a tertiary public hospital with a multidisciplinary approach. METHODS: This retrospective study included all the available (FP) treatments, performed in patients of childbearing age between 2006 and 2022. RESULTS: 1556 patients were referred to the FPP: 332 oocyte vitrification cycles, 115 ovarian cortex cryopreservation with 11 orthotopic autotransplantations, 175 gonadotropin-releasing hormone (GnRH) agonist treatments, 109 fertility-sparing treatments for gynaecological cancer, and 576 sperm cryopreservation were performed. Malignancy was the main indication for FP (the main indications being breast cancer in women and haematological malignancies in men), although non-oncological pathologies, such as endometriosis and autoimmune diseases, have increased in recent years. Currently, the most widely used FP technique is oocyte vitrification, the increase of which has been associated with a decrease in the use of cortex CP and GnRH agonists. CONCLUSIONS: The increase in FP treatment reflects the implementation of reproductive counselling in oncology programmes. A multidisciplinary approach in a tertiary public hospital allows individualised FP treatment for each patient. In recent years, there has been a change in trend with the introduction of new indications for FP and a change in techniques due to their optimisation.
RESUMEN
With the increasing prevalence of obesity among women of reproductive age, the detrimental effects on maternal and neonatal health are increasing. The objective of this review is to summarise the evidence that comprehensive management of weight control in women of reproductive age has on maternal-fetal outcomes. First, the impact that obesity has on fertility and pregnancy is described and then the specific aspects of continued weight management in each of the stages (preconception, pregnancy and postpartum) during these years are outlined, not only to benefit women affected by obesity before pregnancy, but also to avoid and reverse weight gain during pregnancy that complicates future pregnancies. Finally, the special planning and follow-up needs of women with a history of bariatric surgery are discussed in order to avoid nutritional deficiencies and/or surgical complications that endanger the mother or affect fetal development.

RESEARCH QUESTION: Do pregnancies with corpus luteum show different maternal and fetal plasma concentrations of the scavenger proteins haemopexin and α1-microglobulin compared with pregnancies without corpus luteum in preeclampsia? DESIGN: Case-control study of 160 singleton pregnancies: 54 naturally conceived, 50 by IVF after fresh embryo transfer or frozen embryo transfer (FET) in natural cycle (presence of corpus luteum) and 56 after fresh oocyte donation or FET in programmed cycles (absence of corpus luteum). Pregnancies were subclassified into normotensive, preeclampsia and severe preeclampsia cases. Heme-scavenger concentrations were measured by ELISA in maternal and cord plasma collected at delivery. RESULTS: After adjustment, maternal haemopexin was higher in IVF with corpus luteum than in naturally conceived pregnancies in normotensive (Pâ¯=â¯0.038) and preeclampsia (Pâ¯=â¯0.011) populations, and lower in preeclampsia for IVF pregnancies lacking corpus luteum compared with IVF with corpus luteum (Pâ¯=â¯0.002). Maternal α1-microglobulin levels were higher in the absence of corpus luteum only in severe cases of preeclampsia compared with naturally conceived pregnancies (Pâ¯=â¯0.014) and IVF with corpus luteum pregnancies (Pâ¯=â¯0.041). In cord blood, haemopexin was higher in IVF with corpus luteum compared with naturally conceived pregnancies in preeclampsia (Pâ¯=â¯0.039) and α1-microglobulin was higher in the group lacking corpus luteum compared with IVF with corpus luteum in the normotensive population (P < 0.001). CONCLUSIONS: The physiological differences shown for these heme-scavengers between pregnancies after embryo transfer in the presence or absence of corpus luteum support the hypothesis that corpus luteum activity could influence perinatal outcomes. Future research is needed on whether applying potential strategies to develop a corpus luteum might reduce the perinatal complications associated with programmed cycles of IVF.

OBJECTIVES: When bowel preparation (BP) is inadequate, international guidelines recommend repeating the colonoscopy within 1 year to avoid missing clinically relevant lesions. We aimed to determine the rate of missed lesions in patients with inadequate BP through a very early repeat colonoscopy with adequate BP. METHODS: Post hoc analysis was conducted using data collected from a prospective multicenter randomized clinical trial including patients with inadequate BP and then repeat colonoscopy. Inadequate BP was defined as the Boston Bowel Preparation Scale (BBPS) score <2 points in any segment. We included patients with any indication for colonoscopy. The adenoma detection rate (ADR), advanced ADR (AADR), and serrated polyp detection rate (SPDR) were calculated for index and repeat colonoscopies. RESULTS: Of the 651 patients with inadequate BP from the original trial, 413 (63.4%) achieved adequate BP on repeat colonoscopy. The median interval between index and repeat colonoscopies was 28 days. On repeat colonoscopy, the ADR was 45.3% (95% confidence interval [CI] 40.5-50.1%), the AADR was 10.9% (95% CI 8.1-14.3%), and the SPDR was 14.3% (95% CI 10.9-17.7%). Cancer was discovered in four patients (1%; 95% CI 0.2-2.5%). A total of 60.2% of all advanced adenoma (AA) were discovered on repeat colonoscopy. A colon segment scored BBPS = 0 had most AA (66.1%) and all four cancers. CONCLUSION: Patients with inadequate BP present a high rate of AAs on repeat colonoscopy. When a colonoscopy has a colon segment score BBPS = 0, we recommend repeating the colonoscopy as soon as possible.

PURPOSE: The use of fertility preservation (FP) techniques has significantly increased in recent years in the assigned female at birth (AFAB) transgender population. Oocyte cryopreservation is the established method for FP, but ovarian tissue cryopreservation may be considered an alternative option, especially during gender-affirming surgery (GAS). The slow freezing (SF) cryopreservation technique is the standard method for human ovarian tissue, but recently, several studies have shown good results with the vitrification (VT) technique. The objective of this study was to compare the effectiveness of VT and SF techniques in ovarian tissue from AFAB transgender people. METHODS: This was a prospective study including 18 AFAB transgender people after GAS. Ovarian tissue pieces from each ovary were cryopreserved by SF and VT and compared with fresh tissue. Study by light microscopy (LM) assessed follicular morphology and density. The percentage of surviving and degenerated follicles was studied with the tissue viability test. Oocytes, granulosa cells and stroma were analysed separately by transmission electron microscopy. RESULTS: The VT technique preserves follicle and stromal tissue as well as the SF method, but with some differences. Evaluation by LM showed better follicle preservation with VT, but the ultrastructural study showed the presence of minor damage with both techniques compared to fresh tissue. CONCLUSION: Both cryopreservation techniques are accurate for maintaining the follicular population and stromal tissue. Further studies are needed to determine the impact of VT on ovarian tissue and the subsequent follicular activation mechanisms in AFAB ovarian tissue.

RESEARCH QUESTION: What are the hormonal and ovarian histological effects of a gender affirming hormonal therapy in assigned female at birth (AFAB) transgender people? DESIGN: Prospective observational study of 70 AFAB transgender people taking testosterone therapy before gender-affirming surgery (hystero-oophorectomy). A gynaecological ultrasonographic scan was undertaken and serum hormone concentrations measured, including anti-Müllerian hormone (AMH) and androgenic profile. Histological ovarian evaluation was assessed in both ovaries, including the developmental stages of the follicles. RESULTS: The mean age of the population was 27.7+/-5.14 years. The main biochemical parameters were total testosterone levels 781.5 ± 325.9 ng/dl; AMH levels 3.2 ± 1.4 ng/ml; FSH and LH levels 4.9 ± 2.5 IU/l and 3.9 ± 2.9 IU/l, respectively; and oestradiol values 47.6 ± 13.7 pg/ml. Fifty-five AFAB underwent gynaecological ultrasound before surgery and antral follicles were found in 43 out of 47 ultrasounds (91.5%) (without the presence of a dominant follicle or corpus luteum). Histological follicles were mostly in the primordial stage (88.0) and 3.3% were atretic. The thickness of the tunica albuginea was widely heterogeneous (range 0.15-1.45 mm) and luteinization of the stromal cells was observed in 68.6% of the samples. A negative correlation between testosterone levels and total antral follicles was found (Rs= -0.306, Pâ¯=â¯0.029). CONCLUSIONS: AFAB transgender people taking testosterone therapy show cortical follicle distribution in the range previously reported in fertile cisgender women of reproductive age. The follicular population may not be altered as a result of the gender-affirming hormonal therapy, although some cortical and stromal changes have been observed.

The objectives of this study are to assess the prevalence of psychological complaints and changes in sexual function in infertile PCOS women compared with patients with other infertility causes (tubal and male infertility factors) and to identify the predisposing factors. An observational study with three cohorts of infertile women was designed including 37 PCOS patients, 36 women with tubal factor, and 31 women with male factor. Clinical history and physical examination were carried out in all patients. All subjects completed the Hamilton Anxiety Rating Scale, the Beck Depression Inventory, and the Female Sexual Function Index questionnaires. Women with infertility due to PCOS showed a significantly higher prevalence of depressive (48.6 vs 19.4 and 12.9%, p < 0.01) and anxiety symptoms (21.6 vs 5.6 and 3.2%, p = 0.041) than respondents of reference groups. Sexual function in PCOS subjects was impaired in the areas orgasm and satisfaction (p < 0.01 for both) compared to patients of reference groups. Clinical, biochemical hyperandrogenism, and overweight were associated with a higher incidence of depressive and anxiety symptoms in the infertile PCOS group (p < 0.01 for all). Besides, the severity of anxiety symptoms was associated with the number of medically assisted reproduction attempts (p = 0.014). Weight gain and age (p = 0.04 and p = 0.047) were associated with impaired sexual functioning. The relation between reduced sexuality and depressive/anxiety symptoms was found (p = 0.038 and p = 0.012, respectively). Infertile PCOS patients showed the highest prevalence of psychological complaints and some impairment in their sexual functioning. Mental health and sexual functioning need to be part of the routine clinical screening of every PCOS patient. The study was registered at clinicaltrials.gov (identifier: NCT03306459) https://clinicaltrials.gov/ct2/show/NCT03306459?cond=PCOS&cntry=ES&city=Barcelona&draw=2&rank=3.

OBJECTIVE: The aims of this systematic review and meta-analysis were to compare reproductive outcomes in patients who underwent surgery for deep infiltrative endometriosis (DIE) before in vitro fertilization (IVF) with those in patients who underwent IVF without a previous surgery for DIE, to analyze data according to different types of surgery (complete or incomplete) or subgroups of patients (DIE with or without bowel involvement), and to assess surgical and IVF complications and data regarding safety concerns. DATA SOURCES: A systematic literature search from January 1980 to November 2019 with no language restriction was performed in PubMed, MEDLINE, Embase, and Web of Science. The search strategy used the following Medical Subject Headings terms: "in vitro," "fertilization," "IVF," "assisted reproduction," "colorectal," "endometriosis," "deep," "infiltrating," "deep infiltrative endometriosis," "intestinal," "bowel," "rectovaginal," "uterosacral," "vaginal," and "bladder." METHODS OF STUDY SELECTION: We included studies that compared reproductive outcomes in women with infertility with DIE who received IVF with or without a previous surgery for DIE lesions. Meta-analysis was performed using Review Manager (RevMan v.5.3; Cochrane Training, London, United Kingdom). The risk of bias of the included studies was assessed using the method recommended by Cochrane Collaboration. TABULATION, INTEGRATION, AND RESULTS: The systematic search retrieved 150 articles; 98 studies were potentially eligible, and their full texts were reviewed. Of these, 12 studies met our inclusion criteria, and 5 presented data suitable for inclusion in a meta-analysis; however, 2 of the studies provided overlapping data, and only the larger study was finally included. No randomized controlled trials (RCTs) were found. The pregnancy rate per patient was 1.84 (95% confidence interval [CI], 1.28-2.64), the pregnancy rate per cycle was 1.84 (95% CI, 1.26-2.70), and the live birth rate per patient was 2.22 (95% CI, 1.42-3.46) times more likely for operated patients than for nonoperated ones. The addition of data from the incomplete surgery groups also showed a higher pregnancy rate per patient for surgery before IVF (odds ratio [OR] 1.63; 95% CI, 1.16-2.28). The results favor previous surgery in DIE with digestive involvement (OR 2.43; 95% CI, 1.13-5.22) and also in DIE without digestive involvement (OR 1.55; 95% CI, 0.61-3.95). A qualitative analysis of the complications of surgery and IVF showed a partial or complete lack of information on these issues as well as high heterogeneity in the reported data. None of these studies is an RCT; therefore, all have a high risk of selection and allocation bias, except for 1 study that statistically controlled the latter risk by using propensity scores. Funnel plots showed no asymmetry. CONCLUSION: The results were very consistent for all the studied outcomes, showing a statistically significant benefit for surgery before IVF, although they should be confirmed with RCTs. In addition to the reproductive outcomes, safety data should also be reported to obtain a complete assessment of the risks and benefits.

BACKGROUND: There is limited evidence on the impact of bariatric surgery (BS) on reproductive outcomes in the general population and specifically in patients with polycystic ovarian syndrome (PCOS) or the effect of different BS techniques. PURPOSE: The study aims to investigate the impact of BS on fertility, pregnancy, and newborn outcomes in reproductive age women who have undergone BS and the outcomes according to surgical procedure and PCOS diagnosis. MATERIALS AND METHODS: This was a retrospective, descriptive, cross-sectional study performed in women from 18-39 years undergoing BS in our centre from January 2005 to December 2010. We performed a telephone interview including a structured reproductive health survey on fertility, pregnancy, and offspring outcomes before and after BS. RESULTS: Of the women, 872 underwent BS during the study period, 298 were 18-39 years old, and reproductive data was obtained from 217. Women with regular menstrual cycles increased from 52.9% before BS to 72.9% 1 year after surgery. The percentage of patients with a time-to-pregnancy longer than 12 months was higher after laparoscopic sleeve gastrectomy (LSG) (17.8%) compared to laparoscopic Roux-en-Y gastric bypass (7.1%; p = 0.02). Menstrual regularity was less frequent in PCOS (n = 43) (26.0%) compared to non-PCOS women before BS (60.1%; p = 0.01), with no differences after surgery. Several perinatal results showed an improvement after BS, with a reduction in macrosomia rate and birth weight. CONCLUSION: BS was associated with an improvement in several reproductive outcomes. Menstrual regularity was especially improved in PCOS women. Further research may clarify the impact of LSG on fertility.

OBJECTIVE: Follicular Output Rate (FORT) is an efficient quantitative and qualitative marker of ovarian responsiveness to gonadotropins. Transdermal testosterone (TT) has been used as adjuvant therapy to gonadotrophins in order to improve ovarian response in poor responders (PR). The aim of this study was to analyze whether TT can improve follicular sensitivity to gonadotropins using FORT. METHODS: This retrospective study, held in a tertiary-care university hospital included 90 PR patients, according to the Bologna criteria. Patients in Group 1 (n = 46) received transdermal application of testosterone preceding gonadotrophin ovarian stimulation under pituitary suppression. In Group 2 (n = 44) ovarian stimulation was carried out with high-dose gonadotrophin in association with minidose GnRH agonist protocol. We analyzed ovarian stimulation parameters and IVF outcomes. We determined antral follicle count (AFC) (3-8 mm) before ovarian stimulation, pre-ovulatory follicle count (PFC) (16-22 mm) and the day of hCG administration. We calculated the FORT using the PFCx100/AFC ratio. RESULTS: Baseline characteristics and ovarian reserve parameters were similar in both groups. FORT and oocytes retrieved were significantly higher in group 1 vs group 2. There were no significant differences in pregnancy rates. In group 1 there was a significant correlation between FORT and AFC. CONCLUSIONS: This study suggests that the potential beneficial mechanism of TT in poor responder patients may be based on increasing the antral follicle sensitivity to gonadotrophin. FORT is an excellent tool to demonstrate this.

To investigate the quality of life (QoL) of infertile women with polycystic ovary syndrome (PCOS) and analyze the association between the clinical/biochemical features of PCOS and the physical/psychological well-being of patients. An observational study with three independent groups women was designed including 37 infertile PCOS patients, 36 women with tubal factor infertility, and 31 women with male factor infertility referred to the Reproductive Medicine Unit of the Hospital Clinic Barcelona from December 2017 to June 2019. Clinical history, physical examination including Ferriman-Gallwey scores, and vaginal ultrasound were carried out in all patients. All subjects completed the 36-item Short Form Health Survey, and PCOS patients were asked to fill out the Polycystic Ovary Syndrome Questionnaire. The IBM SPSS 23.0 was used for the statistical analysis. Infertile women with PCOS reported significantly worse QoL scores of social functioning (p = 0.049), emotional role functioning (p = 0.041), mental health (p = 0.002), and the mental component summary (p = 0.002) compared with women with other causes of infertility. In addition, body pain (p = 0.006), general health (p < 0.001), and vitality (p = 0.002) scores were significantly lower in women with PCOS compared with those with male factor infertility. Infertile PCOS patients showed low scores in all domains of the PCOSQ. Hirsutism and weight gain were the factors most associated with impaired health-related QoL in PCOS. Infertile PCOS women presented worse QoL mainly due to psychological and emotional distress. The main predictors were clinical manifestations of hyperandrogenism and weight gain.

OBJECTIVE: Transdermal testosterone has been used in different doses and in different stimulation protocols in poor responders. The aim of the present study is to compare the luteal estradiol/GnRH antagonists protocol versus long GnRH agonists in poor responder patients according to the Bologna criteria, in which transdermal testosterone has been used prior to the stimulation with gonadotropins. METHODS: In this retrospective analysis, a total of 141 poor responder patients according to the Bologna criteria were recruited. All patients were treated with transdermal testosterone preceding ovarian stimulation with gonadotropins during 5 days. In 53 patients we used the conventional antagonist protocol (Group 1). In 88 patients (GrH pituitary suppression was achieved by leuprolide acetate according to the conventional long protocol (Group 2). We analyzed the ovarian stimulation parameters and IVF outcomes. RESULTS: Comparing groups 1 and 2, there were no significant differences between cancellation rates and number of oocytes retrieved. However the total gonadotropin dose used and the mean length of stimulation were significantly lower in group 1 when compared to group 2. There were no significant differences in pregnancy outcomes; however, there was a slight increase in the implantation rate in group 1 vis-a-vis group 2, although statistical significance was not achieved. CONCLUSION: TT in poor responder patients can be effective both with the conventional agonist's long protocol and with the conventional antagonist's protocol. However, short regimes with previous estradiol antagonists in the luteal phase facilitate ovarian stimulation by shortening the days of treatment and the consumption of gonadotropins.

Cell-derived microparticles (cMPs) are small membrane vesicles that are released from many different cell types in response to cellular activation or apoptosis. Elevated cMP counts have been found in almost all thrombotic diseases and pregnancy wastage, such as recurrent spontaneous abortion and in a number of conditions associated with inflammation, cellular activation and angiogenesis. cMP count was investigated in patients experiencing unexplained recurrent implantation failure (RIF). The study group was composed of 30 women diagnosed with RIF (RIF group). The first control group (IVF group) (n = 30) comprised patients undergoing a first successful IVF cycle. The second control group (FER group) included 30 healthy women who had at least one child born at term and no history of infertility or obstetric complications. cMP count was significantly higher in the RIF group compared with the IVF and FER groups (P < 0.05 and P < 0.01, respectively) (RIF group: 15.8 ± 6.2 nM phosphatidylserine equivalent [PS eq]; IVF group: 10.9 ± 5.3 nM PS eq; FER group: 9.6 ± 4.0 nM PS eq). No statistical difference was found in cMP count between the IVF and FER groups. Increased cMP count is, therefore, associated with RIF after IVF and embryo transfer.

OBJECTIVE: To analyze natural cycle IVF (NC-IVF) results according to patient age, ovarian reserve status following the Bologna criteria, cause of infertility, and modification of the cycle with the use of GnRH antagonist. DESIGN: Retrospective cohort study. SETTING: Tertiary-care university hospital. PATIENT(S): Nine hundred forty-seven natural cycles carried out in 320 patients. INTERVENTION(S): Analysis of 947 NC-IVF outcomes performed in one single center between January 2010 and December 2014. MAIN OUTCOME MEASURE(S): Pregnancy rates per cycle started, per ET, and per patient, as well as ongoing pregnancy rate at a minimum of 12 weeks of gestation. RESULT(S): Among the three age groups analyzed (≤35 years, 36-39 years, and ≥40 years), pregnancy rates per cycle were significantly lower in the older group of patients (11.4% vs. 11.6% vs. 5.9%). In addition, miscarriage rate (7.7% vs. 34.4% vs. 50%) and ongoing pregnancy rate (10.6% vs. 7.6%vs. 3.0%) were negatively affected by patient age. However, no differences were observed according to patient ovarian reserve status, cause of infertility, or modification of the cycle with GnRH antagonist. The multivariate logistic regression confirmed that patient age was the only variable that could predict pregnancy in NC-IVF cycles (odds ratio, 0.93; 95% confidence interval, 0.88-0.98). CONCLUSION(S): NC-IVF is a feasible and "patient-friendly" option to be offered to young patients, independent of their ovarian reserve status.

OBJECTIVE: To present the results of a large series of patients with ovarian hyperstimulation syndrome treated with a conservative medical approach and to compare the cost of this treatment with outpatient management with paracentesis according to published data. DESIGN: Retrospective case series and cost analysis study using a decision-tree model. SETTING: University hospital. POPULATION: 496 consecutive patients with ovarian hyperstimulation syndrome treated in our center from 1991 to 2010. METHODS: All patients were treated with a conservative medical approach: (a) conservative outpatient approach: bed rest and a low-sodium diet or (b) hospitalized patients: bed rest, low-sodium diet, 20% albumin (60 g/day) and furosemide (20 mg/8 h). MAIN OUTCOME MEASURES: Percentage of admissions, length of hospital stay and readmissions. Total cost of each therapeutic approach. RESULTS: (a) Conservative outpatient approach (n = 377): all cases solved without admission. (b) Hospitalized patients with conservative medical treatment (n = 119): 2.8 days of mean hospital stay, no patient required paracentesis or admission to intensive care unit. Readmissions: Five patients (4.2%) resolved on restarting medical treatment. (c) Cost-analysis comparison: Cost of the outpatient approach with paracentesis: US$980 (range US$519-3557). Cost of conservative medical treatment: US$570 (range US$232-1640). CONCLUSIONS: Ovarian hyperstimulation syndrome can be safely managed with a conservative medical approach, which was not found to be more expensive than outpatient management with paracentesis.

Clinical results were compared in a well-established, assisted reproduction program during the cross-over from highly purified (HP)-human menopausal gonadotropin (hMG) to rhFSH/rhLH. We included the last 33 patients treated with HP-hMG and the first 33 patients receiving rhFSH/rhLH for ovarian stimulation in their first intracytoplasmic sperm injection cycle. Patient baseline characteristics were almost identical in the two groups. Ovarian stimulation characteristics (days of stimulation, total amount of FSH administered using a modest initial loading dose of 150 IU/d, patients with oocyte retrieval) were similar for the two groups. However, the number of total and leading follicles and E2 serum levels on the human chorionic gonadotropin injection day were significantly higher in the rhFSH/rhLH group. The oocyte yield was significantly higher in the rhFSH/rhLH group as well as the number of metaphase II oocytes, difference almost reaching the statistical significance. The number of oocytes fertilized was also higher in patients receiving rhFSH/rhLH treatment. Implantation and clinical pregnancy rates were similar in both the study groups. It is concluded that in women undergoing controlled ovarian hyperstimulation under pituitary suppression for ART, the recombinant combined product containing FSH and LH in a fixed 2:1 ratio is more effective than HP-hMG in terms of follicle development, oocyte yield and quality, and fertilization rates.

BACKGROUND: To study endometrial receptivity in terms of osteopontin (OPN) and αvß3 integrin expression and co-expression in infertile women with early stages of endometriosis. METHODS: We investigated the immunohistochemical expression and co-expression of OPN and αvß3 integrin in the endometrium of 20 infertile patients with Stage I or II endometriosis as the only detectable cause of infertility, 20 infertile patients with unexplained infertility and 20 fertile women undergoing tubal sterilization. Two endometrial biopsies were performed during a single menstrual cycle (postovulatory Day +7 to +8 and 4 days later) in each subject. RESULTS: No statistically significant differences regarding OPN and αvß3 integrin expression were found between infertile patients with endometriosis and the two control groups. There was no significant correlation between OPN and αvß3 integrin staining intensity in the mid-luteal phase biopsies in any of the groups studied. CONCLUSIONS: Endometrial OPN and αvß3 integrin expression or co-expression is not impaired during the window of implantation in patients with Stage I-II endometriosis. Further studies are needed to determine whether these results imply normal endometrial receptivity in such patients or add to the increasing uncertainty about the clinical value of assessing the endometrium with these markers of implantation.

OBJECTIVES: To evaluate the effects of mid-follicular recombinant human luteinizing hormone (rhLH) supplementation in down-regulated women of advanced reproductive age undergoing in vitro fertilization (IVF). STUDY DESIGN: This was a prospective, randomized parallel-group study (allocation 1:1) including 187 normogonadotrophic infertile patients aged ≥ 35 years. Subcutaneous triptorelin was used for pituitary desensitization, and ovarian stimulation was achieved with recombinant human follicle-stimulating hormone (rhFSH) either alone (Group 1) or in combination with rhLH in one of two daily doses: 37.5 IU (Group 2) or 75 IU (Group 3). Ovarian stimulation characteristics and IVF outcome were evaluated. The main outcome was pregnancy rate. RESULTS: A total of 62, 62 and 63 patients were randomized to groups 1, 2 and 3 respectively, and 56, 54 and 55 patients respectively were available for final analysis of the results. Follicular development and oocyte yield were significantly higher in group 1 patients compared with patients in groups 2 and 3. Oocyte maturity and number of oocytes fertilized were also higher in group 1 patients; this difference almost reached statistical significance. No significant difference in implantation and clinical pregnancy rates was found among the three treatment groups. CONCLUSIONS: rhLH supplementation is not a useful tool for patients of advanced reproductive age in ovarian stimulation protocols using an appropriate gonadotrophin-releasing hormone agonist and a step-down regimen of rhFSH.
