Objective: To evaluate the incidence of sperm aneuploidy in men screened for infertility and identify any eventual relation with assisted reproductive outcome.
Design: Controlled prospective study.
Setting: University hospital-based IVF program.
Patient(s): Infertile couples who were screened for sperm aneuploidy and evaluated for IVF treatment.
Intervention(s): Fluorescence in situ hybridization was used to identify chromosomes 18, 21, X, and Y. The assisted reproductive techniques of IVF and intracytoplasmic sperm injection were used for infertility treatment.
Main Outcome Measure(s): The incidence of sperm aneuploidy, semen parameters, fertilization rate, pregnancy characteristics, and rate of neonatal malformations were determined.
Result(s): Oligozoospermic and teratozoospermic men had a significantly higher incidence of chromosomal abnormalities than men with normal semen parameters (2.7% vs. 1.8%). The increased frequency of sperm aneuploidy did not appear to affect pregnancy losses or the occurrence of neonatal malformations.
Conclusion(s): Suboptimal semen samples had a higher incidence of aneuploidy. In this study, the increased frequency of chromosomal abnormalities did not have a direct effect on the fertilization rate, pregnancy characteristics, or neonatal outcome.

Karyotype instability in the germline leads to infertility. Unlike the female germline, the male germline continuously produces fertile sperm throughout life. Here we present a molecular network responsible for maintaining karyotype stability in the male mouse germline.

Given the high morbidity, mortality, and hereditary risk of cardiovascular diseases (CVDs), their prevention and control have garnered widespread attention and remain central to clinical research. This study aims to assess the feasibility and necessity of haplotyping-based preimplantation genetic testing for the prevention of inherited CVD. A total of 15 preimplantation genetic testing for monogenic defect (PGT-M) cycles were performed in 12 CVD families from January 2016 to July 2022.

Article Synopsis
- The manuscript discusses the Intracytoplasmic Sperm Injection (ICSI) procedure and highlights insights gained from 30 years of experience in treating male factor infertility at a specialized center.
- It emphasizes the collaborative efforts of the embryology, andrology, and PGT-A laboratories, which work together with reproductive physicians and urologists to provide comprehensive patient care.
- The focus is on the andrology lab's crucial role in preparing for ICSI, detailing essential considerations like sperm selection, oocyte conditions, necessary equipment, and the procedure's execution.
