The impact of adding hp-hMG in r-FSH started GnRH antagonist cycles on ART outcome.

While luteinizing hormone (LH) activity is believed to play a role in follicle maturation, human chorionic gonadotropin (hCG) might play an important role in implantation process. We aimed to investigate whether addition of human menopausal gonadotropin (hMG) in recombinant-follicle-stimulating hormone (r-FSH) started GnRH antagonist controlled ovarian hyperstimulation (COH) cycles might enhance implantation rate and improve in vitro fertilization (IVF) success. A total of 246 patients undergoing GnRH antagonist IVF cycles were analyzed. One hundred and twenty-three cycles (%50) were treated with only r-FSH and 123 cycles were treated with r-FSH plus hp-hMG combination. Total gonadotropin doses, total number of oocytes retrieved, metaphase 2 (MII) oocytes, top quality embryos, fertilization and implantation rates, clinical pregnancy rates (CPRs) and ovarian hyperstimulation syndrome (OHSS) rates were compared between the groups. Both groups were comparable in terms of demographic details and baseline characteristics. Peak estradiol and progesterone levels in hCG trigger day, number of retrieved oocytes and top quality embryo counts, fertilization rates were similar between the groups. In r-FSH + hp-hMG group, significantly higher implantation rates (35.3% vs 24.3%, p=.017), CPRs (51.2% vs 35.8%, p=.015) and lower OHSS rates (1.6% vs 7.4%, p = .03) were observed respectively compared to r-FSH only treated patients. In conclusion, addition of hp-hMG on the day of antagonist initiation might increase CPRs. A better endometrial receptivity associated with higher implantation rates might be achieved due to hCG component in hp-hMG.

Random start controlled ovarian hyperstimulation for fertility preservation during incidental pregnancy: a case report of blastocyst vitrification from in vitro matured oocytes.

Here, we present a diffuse large B cell lymphoma patient admitted for fertility preservation before cancer therapy and whose pregnancy was recognized incidentally just after the start of random start controlled ovarian stimulation (RSCOH) during the stimulation cycle. Despite an optimal homogenous growth of follicle cohort, majority of the retrieved oocytes were immature after GnRHa trigger. Possible effects of extremely high serum progesterone and/or ß-hCG levels on oocyte in vivo maturation are discussed with the surprising high rate of in vitro maturation and subsequent good embryo development. It seems that in case of need for pregnancy termination as a result of an urgent cancer therapy, RSCOH can be started and patients may benefit from overnight in vitro maturation of oocytes.

Dual trigger with gonadotropin-releasing hormone agonist and recombinant human chorionic gonadotropin improves in vitro fertilization outcome in gonadotropin-releasing hormone antagonist cycles.

AIM: The aim of this study was to evaluate whether dual trigger with leuprolide acetate plus recombinant human chorionic gonadotropin (hCG) improves in vitro fertilization outcome in gonadotropin-releasing hormone antagonist cycles. METHODS: A total of 156 patients diagnosed with mild male factor, unexplained or tubal factor infertility were enrolled in the study. All subjects were allocated into one of two groups: the dual trigger group (leuprolide acetate 500 µg + recombinant hCG 250 µg) and the standard group (recombinant hCG 250 µg) according to the selected trigger method. Oocyte trigger was performed when at least three follicles >17 mm were observed. Pregnancy rate, number of collected oocytes, number of metaphase II oocytes, number of grade-A embryos, cycle cancellation rate, and ovarian hyperstimulation syndrome rate were the main outcome measures for the study. RESULTS: The mean number of grade-A embryos (1.6 ± 1.5 vs 1.1 ± 1.4, P = 0.01) and of metaphase II oocytes (7.9 ± 4.6 vs 6.3 ± 5.8, P = 0.02) was significantly higher in the dual-trigger group. Pregnancy rate was significantly higher in the dual-trigger group than in the standard group (54.8 vs 37.5%, P = 0.006). Two cases of mild ovarian hyperstimulation syndrome were observed in each group. CONCLUSION: This novel and more physiological trigger approach using 500 µg leuprolide acetate plus 250 µg recombinant hCG may lead to an increase in the number of metaphase II oocytes, grade-A embryos, and may improve pregnancy rates.

The ratio of anterior anogenital distance to posterior anogenital distance: A novel-biomarker for polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age. The etiopathogenesis of the disease remains uncertain. Additionally, a full consensus has not been reached regarding PCOS diagnostic criteria. Several attempts have been made to diagnose PCOS with a simple clinical biomarker, but most of them failed. This study aims to investigate the possible association between PCOS and anogenital distance (AGD), which is an important sign of intrauterine androgen exposure. METHODS: A prospective cohort study was conducted on 130 women. The study group contained 65 women with PCOS whereas 65 healthy women were recruited for the control group, all between 18 and 40 years in age. The groups were compared in terms of demographics and clinical and laboratory parameters. Both anterior and posterior AGDs and associated ratios were recorded for each woman. RESULTS: The mean ratio of anterior AGD to posterior AGD for the PCOS and control group were 4.4 ± 1.0 and 4.9 ± 1.0, respectively (p = 0.003). Regression analysis demonstrated that this ratio significantly and positively correlated with the waist to hip ratio and negatively correlated with the free androgen index. CONCLUSION: AGD was initially used to define sexual differentiation of animals. Subsequent human studies showed that boys have longer AGDs than girls. Recent studies supporting the hypothesis that extreme prenatal androgen exposure contributes to PCOS found that AGD in adult PCOS patients was longer than control PCOS patients. However, a novel biomarker other than AGD needs to be identified to standardize these measurements. This work represents the first study to evaluate the ratio of anterior AGD to posterior AGD in PCOS patients. In this study, AGD anterior and posterior measurements were longer in PCOS patients than in controls. However, the strongest predictor of PCOS is the ratio of anterior to posterior AGD.

Metformin therapy improves ovulatory rates, cervical scores, and pregnancy rates in clomiphene citrate-resistant women with polycystic ovary syndrome.

OBJECTIVE: To evaluate the effect of metformin therapy on hyperandrogenism, insulin resistance, cervical scores, ovulation, and pregnancy rates in clomiphene citrate-resistant women with polycystic ovary syndrome (PCOS). DESIGN: Prospective, randomized, double-blind, placebo-controlled study. SETTING: Infertility clinic of a tertiary referral center. PATIENT(S): Fifty-six women with clomiphene citrate-resistant PCOS. INTERVENTION(S): Two cycles of oral metformin therapy (850 mg, twice daily) in group I and placebo therapy (twice daily) in group II. Clomiphene citrate (100 mg/day) on cycle days 3-7 of the second cycle in both groups. MAIN OUTCOME MEASURE(S): Insulin, T, DHEAS, FSH, LH, body mass index (BMI), waist-to-hip ratio, endometrial thickness, cervical score, ovulation, and pregnancy rates in clomiphene-induced cycles after metformin therapy. RESULT(S): Metformin therapy resulted in a significant decrease in total T, LH level, LH/FSH ratio, insulin resistance, and mean BMI. No difference in waist-to-hip ratio, DHEAS level, and fasting insulin level was observed. Clomiphene citrate induction resulted in higher ovulation rates and thicker endometrium in the metformin group than in the placebo group. There was higher cumulative pregnancy rate in the metformin group; however, there was no significant difference in the pregnancy rate between the two groups. CONCLUSION(S): Metformin therapy not only decreases hyperandrogenism and insulin resistance but also improves ovulation rates, cervical scores, and pregnancy rates in clomiphene citrate-resistant women with PCOS.

Circulating Spexin levels in pregnant women with and without gestational diabetes

Background: Several previous studies suggest that SPX plays a role in appetite control and body weight and blood glucose regulation. The aim of this study to determine SPX levels in healthy pregnancies and in gestational diabetes (GDM) and to investigate the association of SPX levels with weight gain and lipid and glucose metabolism in subjects with and without GDM.Methods: A total of 44 women with GDM and 44 women without GDM were randomly enrolled who applied for GDM screening during the 24-28th week of pregnancy. Demographics, blood glucose and lipid profiles and Spexin levels were compared between groups.Results: The mean age, BMI, and weight gain during pregnancy were higher in the GDM group. The LDL cholesterol, Hba1c, SPX and glucose levels in response to OGTT were higher in the GDM group. The SPX levels were correlated with Hba1c and blood glucose levels after OGTT, and were not correlated with the age, BMI, weight gain during pregnancy, lipid parameters, and fasting blood glucose levels in the whole study population.Conclusions: SPX levels were higher in the GDM group compared with non-GDM group and SPX levels were correlated with HbA1c levels and post-OGTT glucose levels but not with fasting glucose levels.

Multinodular hydropic leiomyoma of the uterus with perinodular hydropic degeneration and extrauterine extension.

Multinodular hydropic leiomyoma (MHL) of the uterus is one of the rarest variants of uterine leiomyomas and can create some diagnostic problems. Only five cases have been reported previously. We describe an MHL with perinodular hydropic degeneration in a 48-year-old woman. Gross examination revealed a large and predominantly intramural, edematous multinodular uterine tumor and extrauterine, small grape-like nodules overlying the lateral surface of the uterine serosa. Histologically, the tumor was composed of extra-intrauterine benign, small smooth muscle nodules with perinodular hydropic degeneration, prominent intramural dissecting growth pattern, and satellite nodules closely resembling vascular invasion. Immunohistochemically, these cells stained for desmin, smooth muscle actin and vimentin. The patient had no evidence of disease for 18 months after hysterectomy. Multinodular hydropic leiomyoma is a clinically benign tumor and should not be confused with intravenous leiomyomatosis and some other unusual leiomyoma variants.
