Demographic distributions and clinical results of assisted reproduction techniques in Turkey in 2019: a descriptive survey.

Objective: The aim of this study was to describe characteristics and outcomes of assisted reproductive technology (ART) cycles performed in 2019 in Turkey.

Material And Methods: One-hundred and sixty-five ART centers in Turkey were invited to submit data. The survey was sent to center directors via e-mail with anonymous links by Qualtrics™.

Individual variation of the percentage of Y-chromosome bearing sperm content in human ejaculates.

The study aimed to determine the variation of Y-chromosome-bearing sperm content among individual ejaculates. A real-time polymerase chain reaction (qPCR) with unique primers was developed and used to calculate the percentage of Y-chromosome-bearing sperm in individual ejaculates from 50 randomly selected men. There was a significant difference in the overall mean ± SD between the proportion of Y-chromosome-bearing sperm and X-chromosome-bearing sperm (45.

Live birth after transfer of a tripronuclear embryo: An intracytoplasmic sperm injection as a combination of microarray and time-lapse technology.

Although around 1-4% of human zygotes have been found to be tripronuclear, there is little information about the subsequent development and chromosomal composition of embryos that derive from these zygotes. Herein, we report a pregnancy and subsequent delivery of a healthy newborn after the transfer of a blastocyst that developed from a tripronuclear zygote that had a euploid microarray result.

Reproducibility of a time-lapse embryo selection model based on morphokinetic data in a sequential culture media setting.

Objective: To compare the outcomes of embryos that were given a dynamic score based on a preconstructed embryo scoring model and to analyze whether this model complies with our data.

Material And Methods: A total of 910 transferred embryos with known implantation data were retrospectively analyzed in this study. All of the embryos were given a dynamic score based on the preconstructed hierarchical embryo scoring model.

Frequency of embryo multinucleation detected by time-lapse system and its impact on pregnancy outcome.

Objective: To compare the detection rate of multinucleation with the time-lapse system and conventional control timing proposed by European Society of Human Reproduction and Embryology (ESHRE) consensus and evaluate its impact on pregnancy rates.

Design: Retrospective study.

Setting: A private IVF center.

The risk of ectopic pregnancy following GnRH agonist triggering compared with hCG triggering in GnRH antagonist IVF cycles.

Purpose: The aim of this study was to compare the incidence of ectopic pregnancy in GnRH agonist triggered IVF cycles with intensive luteal support versus hCG triggered IVF cycles.

Methods: This study was conducted as a retrospective cohort analysis of women who underwent IVF treatment employing GnRH agonist or recombinant hCG (rhCG) triggers during 2-year period. The medical charts of women who achieved pregnancies were reviewed and their demographic characteristics, infertility reasons and IVF data were recorded.

Is apolipoprotien E codon 112 polymorphisms associated with recurrent pregnancy loss?

Problem: To compare the prevalence of 112T>C point mutations among women experiencing RPL with fertile control women.

Method Of Study: Buccal swabs were obtained from 232 individuals: 136 with a history of >or=2 abortions, 37 with at least 2 live births and 59 with a history of deep vein thrombosis (DVT). DNA was extracted and PCR amplification of Apo E codons was performed.

Letrozole versus human menopausal gonadotrophin in women undergoing intrauterine insemination.

This pilot study was conducted to compare the results of intrauterine insemination (IUI) under ovarian stimulation with either letrozole (Femara) or human menopausal gonadotrophin (HMG). A randomized controlled trial was conducted. Eighty women aged 20-35 years with unexplained infertility of at least 2 years' duration were randomized according to a computer-generated randomization list into the letrozole group and the HMG group.

Administration of alternate day triptorelin for controlled ovarian hyperstimulation is cost effective.

Gonadotropin-releasing hormone agonists in an alternate-day dosage resulted in similar clinical pregnancy rates as the daily protocol. No premature luteinization was reported in either group. Total GnRH agonist dosage in the alternate-day protocol was significantly reduced.
