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.

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.

Klinefelter syndrome is the most frequent chromosomal abnormality in patients with nonobstructive azoospermia. The development of advanced assisted reproductive techniques, such as testicular sperm extraction and intracytoplasmic sperm injection, has provided the possibility of biological fathering in nonobstructive azoospermic patients with Klinefelter syndrome. We aimed to evaluate our sperm retrieval rate by microdissection testicular sperm extraction and to analyse the intracytoplasmic sperm injection outcomes in these patients. Medical records of 110 nonobstructive azoospermic patients with Klinefelter syndrome were retrospectively reviewed. We found that the sperm retrieval rate by microdissection testicular sperm extraction is lower than published reports on other types of secretory azoospermia. The statistical analyses yielded that age, FSH and testosterone levels as predictive factors for successful sperm retrieval.

Direct follicle aspiration versus flushing in poor responders yields similar metaphase II oocytes.

PAPP-A was significantly associated with SGA after controlling for confounders.

Conservative treatment of endometrial carcinoma is safe in most cases. However, patients should be well-informed about the risks of conservative treatment because delaying definitive treatment sometimes worsens the prognosis.

Numerical abnormalities of sex chromosomes are seen approximately 1 in 400 live births. Pentasomy X is a very rare chromosomal abnormality and it is defined as presence of five X chromosomes instead of two. Prenatal sonographic features have rarely been described in the literature before. Here we present a non-immune fetal hydrops diagnosed during the 17th week of gestation. Ultrasonographic examination revealed subcutaneous edema, pleural effusion and ascites, and also clinodactyly of the fifth fingers of both hands. The fetal karyotype was assessed as 49,XXXXX (pentasomy X) in two different culture flasks. Hydropic signs regressed at 21 weeks' gestation. Prenatal diagnosis may not be possible usually for this rare chromosomal abnormality. Every anomaly detected prenatally, such as transient hydrops, may help us to diagnose pentasomy X.
