Recurrent pregnancy loss (RPL) is a serious complication of pregnancies, affecting almost 2%-5% of couples. Among numerous underlying causes, chromosomal anomalies in one of the partners are regarded as important issues, with varying frequencies among different populations. SBI-115 cost In this study, we aimed to determine the prevalence of chromosomal abnormalities and chromosome polymorphisms in couples with a history of RPL from Kermanshah province, west of Iran.

In this 11-year retrospective study, a total of 1140 cases with two or more spontaneous abortions were recruited and studied according to standard cytogenetic analysis.

From a total of 1140 reviewed blood samples, 1011 people (88.5%) had a normal karyotype and 129 people (11.5%) had chromosomal aberrations. These aberrations were found in 62 females and 67 males. The prevalence of chromosomal abnormalities was as follows 18 (1.5%) structural aberrations, 1 numerical anomaly and 110 (9.6%) apparently normal polymorphic variants.

Our findings could determine the underlying cause of RPL in 1.5% of the population while the majority still remained unexplained. This emphasizes the importance of searching for other genetic and nongenetic causes of RPL in apparently idiopathic cases of RPL.

Human reproduction is the most intricate event as ~ 20% of human pregnancies end in miscarriages for which chromosomal anomalies are a common factor. The chromosomal variations associated with reproductive failures include translocations, inversions, supernumerary marker chromosomes, heterochromatic polymorphisms, etc., Till date, the significance of heteromorphic variants in reproductive failures is unclear.

The aim of this study is to investigate the role of chromosomal anomalies and polymorphic variations in reproductive failure.

Chromosomal analysis using GTG banding was performed on 638 couples (1276 individuals).

In the present study, 138 of 1276 individuals showed chromosomal variations with respect to heterochromatic variants and Robertsonian translocations. The most common variants observed across the population studied were the pericentric inversion of the chromosome 9 [inv(9)(p11q13), 3.68%] followed by pstk + on the short arm of chromosome 15 (15pstk+, 1.95%) and Robertsonian translocationsable for patients suffering from infertility, reproductive failures and pregnancy losses before IVF treatment to rule out the carrier status.
Azoospermia is a highly evolving subject in the last few decades. In the past, use of donor sperm was the only option providing a realistic chance of conception for couples affected by azoospermia. Introduction of sperm retrieval techniques and assisted reproductive technologies, especially intracytoplasmic sperm injection (ICSI), has provided these men a chance to father their genetically own child and changed the management approach significantly.

The objective was to compare the sperm retrieval rate (SRR) and ICSI outcomes of surgically retrieved sperms in cases of obstructive and nonobstructive azoospermia (NOA) as well as to evaluate the efficacy of sperm retrieval techniques.

A total of sixty azoospermic patients were included in the study. The patients were divided between OA (16) and NOA groups (44). A retrospective outcome analysis was done on SRR and ICSI results among them.

The overall SRR in patients with NOA and OA was 47.7% and 100%, respectively (
< 0.001). On subgroup analysis, hially fertile. A systematic approach especially in patients with NOA is an important step. Microdissection testicular sperm extraction is an attractive option for NOA patients in order to increase the chances of successful sperm retrieval.
The aim is to study the effect of follicle-stimulating hormone (FSH) administration on the day of human chorionic gonadotropin (hCG) trigger on the assisted reproductive technique (ART) outcomes in
fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles.

Retrospective cohort study was conducted in the ART center of our hospital.

Two hundred and ninety IVF/ICSI cycles performed between September 2012 and August 2017 were included in the study. Patients who received 375 IU of FSH on the day of hCG trigger (149 cycles) were compared with those who did not receive FSH on the day of trigger (141 cycles).

Chi-square test and Student's
-test were used.

The FSH co-administered group had a significantly higher number of oocytes retrieved, mature oocytes, and fertilization rate compared to those who did not receive FSH on the day of trigger (
< 0.001). The total number of embryos, the number of grade 1 embryos and the number of embryos available for cryopreservation were also significantly the total number of oocytes retrieved and the number of mature oocytes but no significant change in the implantation, clinical pregnancy, and live birth rates.
A premature luteinizing hormone (LH) surge, in
fertilization (IVF) cycles with gonadotropin-releasing hormone (GnRH)-antagonist downregulation, leads to cycle cancellation. Currently, risk factors for the development of premature LH surge remain unknown.

The aim of the study was to determine the incidence and identify the contributing factors for premature LH surge in IVF cycles with GnRH antagonist suppression.

This was a retrospective cohort study.

IVF-embryo transfer program at a fertility and research center.

The study included all patients undergoing IVF from December 1, 2014, to November 30, 2018, in whom GnRH-antagonist (cetrorelix 0.25 mg/d) flexible protocol was used. The primary outcome measure was the identification of premature LH surges (documented by a 2.5-fold increase in LH from the baseline above a threshold of 17 mIU/mL) with or without a decrease in E
and appearance of free fluid on ultrasound.

Premature LH surges occurred in 15 (2.16%) of 692 patients undergoing IVF with GnRH-antagonist suppression.
