In women stimulated with GnRHa and hMG/FSH for IVF, elevated serum progesterone levels on the day of hCG administration were associated with diminished implantation rates and live birth rates regardless of ovarian reserve.

Our study did not find any difference in LBRs between single and double IUI groups in OH cycles with multi-follicular development. To the best of our knowledge this is the first report with this kind of study design. The study was registered at clinicaltrials.gov: NCT 00993902.

Cesarean scar pregnancy (CSP) is a rare type of ectopic pregnancy, which occurs in previous cesarean section scar tissue, with an incidence of 1 in 1800–3000 pregnancies. Transvaginal ultrasound‐guided local methotrexate (MTX) administration presents as a non‐systemic option with possible better penetration to the pregnancy site. We present the management of 18 patients with CSP solely by transvaginal ultrasound‐guided local MTX administration. All patients were treated with local MTX with a dose of 50 mg/m2. Eleven (61.1%) of the patients did not need any further intervention. Four patients (22.2%) were treated with additional single‐dose systemic MTX due to inadequate alteration in blood β‐human chorionic gonadotrophin levels. Three patients (16.7%) required hysteroscopy and/or laparotomy. We suggest that transvaginal ultrasound‐guided local MTX treatment may be considered as a first‐line treatment for CSP.

Purpose The new-generation spermatozoon selection method, microfluidic technique called Fertile Chip ® gives the chance to select spermatozoa with lower DNA fragmentation indexes. We aimed to determine the effect of microfluidic techniques for spermatozoon selection in ICSI treatment in patients with unexplained infertility. Methods This prospective randomized controlled study was conducted at a university hospital. One hundred twenty-two couples with unexplained infertility were included, in which 61 of them were treated with conventional swim-up techniques (control group) and another 61 with the microfluidic technique (study group) for spermatozoon selection in IVF treatment. The fertilization rates and the quality of embryos were the primary outcomes, and clinical pregnancy (CPR) and live birth rates (LBR) were the secondary outcomes of our study.Results CPR in the study group and control group were 48.3% and 44.8% (p = 0.35) and LBR were 38.3% and 36.2% (p = 0.48), respectively. The fertilization rates were similar (63.6% and 57.4%, p = 0.098). A total number of grade 1 embryos were significantly higher in microfluidic technique group than in control group (1.45 ± 1.62 vs. 0.83 ± 1.03, p = 0.01). There were more surplus top quality embryos leftover to freeze in the study group (0.71 ± 1.48 vs. 0.22 ± 0.69, p = 0.02). Conclusion Our study showed that the microfluidic technique does not change fertilization, CPR, and LBR during IVF treatment for couples with unexplained infertility. Despite the fact that the total number of grade 1 embryos after ICSI treatment and the surplus number of grade 1 embryos after embryo transfer were higher in the microfluidic technique group, the study was not powered to detect this difference. Trial registration NCT02488434

Objective:The correlation between dysmorphic uterus and infertility still remains enigmatic. We evaluated the reproductive outcomes of metroplasty via office hysteroscopy in unexplained infertile women with dysmorphic uteri.Materials and Methods:In this retrospective cohort study, metroplasty via office hysteroscopy using a bipolar system was performed to 272 women with unexplained infertility with dysmorphic uteri from January 2013 to January 2016. Of all the patients, 162 had primary infertility, and 110 had secondary infertility.Results:In the primary infertility group, the clinical pregnancy rate was 45.68% (74/162) and the live birth rate was 38.9% (63/162), and in the secondary infertility group, the clinical pregnancy rate was 55.45% (61/110) and the live birth rate was 49% (54/110) after metroplasty. In the secondary infertility group, the miscarriage rate and especially the ectopic pregnancy rate declined dramatically [from 84.5% (93/110) to 9.8% (6/61) and from 15.5% (17/110) to 1.6% (1/61), respectively] (p<0.01).Conclusion:Reproductive outcome can be impaired by Müllerian anomalies, hence, infertile women with dysmorphic uteri should undergo hysteroscopy to improve reproductive outcomes. Our study demonstrated that office hysteroscopic metroplasty of a dysmorphic uterus might improve fertility, particularly in patients with unexplained infertility with dysmorphic uteri, which was an ignored factor previously. Office hysteroscopy is an alternative option in terms of non-invasive procedure.

Cervical mucus aspiration before IUI might improve clinical pregnancy rates by yet-to-be-defined mechanisms.

The presence of irregular vaginal bleeding was not a predictor of malignancy in the polyp. Premenopausal women with PCOS and those with 2 or more polyps had an increased prevalence of polyp malignancy. These groups of patients, whether symptomatic or not, should be evaluated by hysteroscopic resection of the polyps.
