Evaluation of chromosomal abnormalities and Y-chromosome microdeletions in 1696 Turkish cases with primary male infertility: A single-center study.

Objective: The aim of this study was to determine the frequencies of chromosomal abnormalities and Y-chromosome microdeletions in Turkish cases with primary male infertility in a single center.

Material And Methods: Chromosomal abnormalities and Y-chromosome microdeletions were investigated in 1696 cases with primary male infertility between 2012 and 2017. Karyotype analyzes and Y-chromosome microdeletions analyzes [azoospermia factor (AZF) regions] were performed in all cases by using standard cytogenetic methods and the multiplex polymerase chain reaction method, respectively.

The relationship between serum hormone levels (follicle-stimulating hormone, luteinizing hormone, total testosterone) and semen parameters.

Objective: The aim of this study was to investigate the effect of serum gonadotropin and total testosterone levels on semen parameters.

Materials And Methods: Three hundred and eighty-two patients that applied to a male infertility polyclinic were included in our study. Serum gonadotropin and total testosterone levels and semen parameters of the patients were analyzed during the first visit to the clinic.

Effect of the afterloaded external guidance embryo transfer technique on pregnancy rates in single embryo transfer cycles.

Objective: To investigate effect of the afterloaded external guidance embryo transfer technique on pregnancy rates in single embryo transfer intracytoplasmic sperm injection (ICSI) cycles.

Material And Methods: This retrospective study was performed at the Dr. Zekai Tahir Burak Women's Health Research and Education Hospital.

New end-to-end microvascular anastomosis with geometrically adaptable ends technique: an experimental study on rats.

Objective: The aim of this study was to develop an effective arterial anastomosis model with a high patency rate and low operation time. We introduced a new end-to-end microvascular anastomosis with geometrically adaptable ends.

Methodology: In this technique, two triangular flaps were prepared at the end of the vessels and four stitches applied on the tip of those flaps.

Treatment with oxytocin antagonists before embryo transfer may increase implantation rates after IVF.

This report aimed to examine the effects of atosiban on pregnancy outcome after IVF-embryo transfer. A prospective, randomized, placebo-controlled clinical study was performed. A total of 180 women undergoing intracytoplasmic sperm injection who had top-quality embryos were randomly allocated into treatment and control groups.
