Sperm Chromatin Condensation Defect Accelerates the Kinetics of Early Embryonic Development but Does Not Modify ICSI Outcome.

The origin and quality of gametes are likely to influence the kinetics of embryonic development. The purpose of the study was to assess the impact of sperm nuclear quality, and in particular sperm chromatin condensation, on the kinetics of early embryo development after intracytoplasmic sperm injection (ICSI). Our study included 157 couples who benefitted from ICSI for male factor infertility.

Experience, and gynaecological and reproductive health follow-up of young adult women who have undergone ovarian tissue cryopreservation.

Research Question: What are the experience, and gynaecological and reproductive health outcomes in young adult women who have undergone ovarian tissue cryopreservation (OTC)?

Design: A retrospective observational study was conducted at a single institution between May 2019 and February 2021 including 87 women aged over 18 years undergoing OTC. Medical characteristics and questionnaire data collected more than 18 months after OTC were analysed.

Results: Close to 74% (n = 64/87) of women had a follow-up consultation and completed the questionnaire.

Sperm chromatin condensation defects, but neither DNA fragmentation nor aneuploidy, are an independent predictor of clinical pregnancy after intracytoplasmic sperm injection.

Purpose: The impact of sperm DNA damage on intracytoplasmic sperm injection (ICSI) outcomes remains controversial. The purpose of the study was to evaluate the prognostic value of several types of sperm nuclear damage on ICSI clinical pregnancy.

Methods: Our retrospective study included a total of 132 couples who consulted for male or mixed-factor infertility that benefited from ICSI cycles from January 2006 to December 2015.

In vitro fertilization outcomes after ablation of endometriomas using plasma energy: A retrospective case-control study.

Objective: Ovarian endometrioma ablation using plasma energy appears to be a valuable alternative to cystectomy, because it could spare underlying ovarian parenchyma resulting in high spontaneous and overall pregnancy rates. After initial postoperative decrease, anti-mullerian hormone (AMH) level progressively increases several months after ablation. The aim of our study was to assess the outcomes of in vitro fertilization (IVF) in women managed for ovarian endometriomas by ablation using plasma energy, when compared to those in women free of endometriosis.
