A septate uterus with double cervix during two pregnancies: pregnancy outcome before and after cervix sparing metroplasty. A case report.

In this case report we present a patient with different pregnancy outcomes after IVF treatments. After an extremely premature delivery in her first pregnancy, a vaginal 3D ultrasound scan revealed a correct diagnosis for her uterine anomaly: A complete uterine septum, double cervix and non-obstructive longitudinal vaginal septum, classified as U2bC2V1 according to the European Society of Human Reproduction and EmbryologyEuropean Society for Gynaecological Endoscopy (ESHRE-ESGE)-classification. She underwent a cervix sparing metroplasty and had a spontaneous vaginal birth at 41+2 weeks gesttation. For patients with otherwise unexplained infertility or earlier premature delivery, a diagnostic workup, oriented to the research of uterine malformations, should be taken into consideration.

Use of metformin before and during assisted reproductive technology in non-obese young infertile women with polycystic ovary syndrome: a prospective, randomized, double-blind, multi-centre study.

BACKGROUND: To study the effect of metformin before and during assisted reproductive technology (ART) on the clinical pregnancy rate (CPR) in non-obese women with polycystic ovary syndrome (PCOS). METHODS: A multi-centre, prospective, randomized, double-blind study was conducted in eight IVF clinics in four Nordic countries. We enrolled 150 PCOS women with a body mass index <28 kg/m(2), and treated them with 2000 mg/day metformin or identical placebo tablets for ≥ 12 weeks prior to and during long protocol IVF or ICSI and until the day of pregnancy testing. The primary outcome measure was CPR. Secondary outcome measures included spontaneous pregnancy rates during the pretreatment period, and the live birth rate (LBR). RESULTS: Among IVF treated women (n = 112), biochemical pregnancy rates were identical in both groups (42.9%), and there were no significant differences in the metformin versus the placebo group in CPR [39.3 versus 30.4%; 95% confidence interval (CI): -8.6 to 26.5]. The LBR was 37.5 versus 28.6% (95% CI: -8.4 to 26.3). However, prior to IVF there were 15 (20.3%) spontaneous pregnancies in the metformin group and eight (10.7%) in the placebo group (95% CI: -1.9 to 21.1; P = 0.1047). According to intention to treat analyses (n = 149); significantly higher overall CPR were observed in the metformin versus placebo group (50.0 versus 33.3%; 95% CI: -1.1 to 32.3; P = 0.0391). LBR was also significantly higher with use of metformin versus placebo (48.6 versus 32.0; 95% CI: 1.1 to 32.2; P = 0.0383). No major unexpected safety issues or multiple births were reported. More gastrointestinal side effects occurred in the metformin group (41 versus 12%; 95% CI: 0.15 to 0.42; P < 0.001). CONCLUSIONS: Metformin treatment for 12 weeks before and during IVF or ICSI in non-obese women with PCOS significantly increases pregnancy and LBRs compared with placebo. However, there was no effect on the outcome of ART per se. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT00159575.

Metformin treatment before IVF/ICSI in women with polycystic ovary syndrome; a prospective, randomized, double blind study.

BACKGROUND: Our aim was to investigate the effect of pre-treatment with metformin in women with polycystic ovary syndrome (PCOS) scheduled for IVF stimulation. METHODS: Seventy-three oligo/amenorrhoeic women with polycystic ovaries and at least one of the following criteria: hyperandrogenaemia, elevated LH/FSH ratio, hyperinsulinism, decreased SHBG levels or hirsutism, were studied. Normal weight and overweight patients were randomized separately in a prospective, randomized, double blind study. All patients were treated for at least 16 weeks with metformin (1000 mg bid) or placebo ending on the day of HCG injection. RESULTS: No differences were found in the primary end-points: duration of FSH stimulation 14.4 (13.1-15.7) versus 14.2 (12.6-15.7) days or estradiol on the day of HCG injection 6.8 (5.3-8.2) versus 7.6 (5.6-9.6) nmol/l in the metformin and placebo groups, respectively. The secondary end-points number of oocytes, fertilization rates, embryo quality, pregnancy rates and clinical pregnancy rates were equal. However, in the normal weight subgroup (BMI <28 kg/m(2), n = 27), pregnancy rates following IVF were 0.71 (0.63-0.79) versus 0.23 (0.15-0.31) in the metformin and placebo groups, respectively (P = 0.04). Overall clinical pregnancy rates were equal: 0.51 (0.34-0.68) versus 0.44 (0.27-0.62) in the metformin and placebo groups, respectively. However, in the normal weight subgroup, clinical pregnancy rates were 0.67 (0.43-0.91) and 0.33 (0.06-0.60), respectively (P = 0.06). CONCLUSIONS: Pre-treatment with metformin prior to conventional IVF/ICSI in women with PCOS does not improve stimulation or clinical outcome. However, among normal weight PCOS women, pre-treatment with metformin tends to improve pregnancy rates. Further studies in subgroups of PCOS women are required.
