Cytogenetic analysis of early pregnancy loss after assisted reproduction treatment using intracytoplasmic sperm injection.

Objectives: To evaluate the incidence of numerical chromosomal abnormalities in the patients with early pregnancy loss (EPL) following in vitro fertilization, and evaluate the role of different confounders of the risk of chromosomal abnormality-related pregnancy loss.

Material And Methods: A retrospective chart review of all patients from our in vitro fertilization (IVF) center who conceived using assisted reproduction techniques between April 2017 and 2019, who experienced a subsequent early pregnancy loss, and whose abortus materials were successfully karyotyped were included.

Results: Of the 243 patients experienced an early loss, the overall rate of chromosomal abnormality was 46.

The effect of intrauterine insemination preceding frozen-thawed elective single embryo transfer in couples with unexplained subfertility.

Introduction: This prospective randomized controlled trial aimed to evaluate the effect of intrauterine insemination (IUI) before frozen-thawed elective single embryo transfer (FT-eSET).

Material And Methods: A total of 200 couples with unexplained subfertility underwent fertilization (IVF) treatment. Patients were randomly assigned to either FT-eSET or IUI preceding FT-eSET.

Relationship between Endometrial Thickness and In Vitro Fertilization-Intracytoplasmic Sperm Injection Outcome.

Background: This study assessed the relationship between endometrial thickness on day of human chorionic gonadotropin (hCG) administration and in vitro fertilizationintracytoplasmic sperm injection (IVF-ICSI).

Materials And Methods: This prospective cross-sectional study included a total of 593 women. Patients were treated with either the agonist or antagonist protocol according to the clinician's and patient's preference.

Comparison of GnRH agonist and antagonist protocols in normoresponder patients who had IVF-ICSI.

Purpose: To measure the estradiol (E2) and progesterone levels on day of human chorionic gonadotropin (hCG) and to assess follicular development, pregnancy rates and IVF-ICSI outcomes comparing gonadotropin releasing hormone (GnRH) agonist and antagonist protocols.

Methods: A total 195 women were included in the study. The patients were treated with agonist or antagonist protocol according to the clinician's and patient's preference.

Efficacy of the local endometrial injury in patients who had previous failed IVF-ICSI outcome.

Background: The latest studies reported that local endometrial injury is a useful method to improve the success of IVF-ICSI outcome.

Objective: To assess whether local endometrial injury occurred by Pipelle in the spontaneous cycle could improve implantation rate, cleavage rate, and pregnancy outcome in the subsequent IVF-ICSI cycle in patients who had recurrent IVF failure.

Materials And Methods: An endometrial biopsy was performed on day 21(st) in 41 patients as intervention group in this retrospective cross-sectional study.

Is follicular flushing really effective? A clinical study.

Purpose: Oocyte retrieval under transvaginal ultrasonographic guidance has been used for in vitro fertilization-intracytoplasmic sperm injection. Despite considerable advances in the assisted reproductive techniques, the efficacy of follicular flushing during egg collection remains controversial. The aim of this study was to compare the follicular aspiration only and aspiration + flushing methods in terms of retrieved oocyte number and clinical pregnancy rates.
