The proportions of good, fair, and poor embryos in 13 women with bilateral endometriomas were compared with those of 39 women without endometriomas and were found to be similar (47.2% vs. 41.1%, 28.3% vs. 32.8%, and 24.3% vs. 26.0%, respectively). Therefore, it appears that the presence of bilateral endometriomas during IVF treatment is not associated with reduced embryo quality.

The quality and quantity of stripped and testicular wild northern pike (Esox lucius) sperm was compared and the effectiveness of short-term storage was assessed. Stripped sperm (SS) was collected using abdominal massage. Next, the fish were decapitated and the testes were removed.

Purpose: To examine the association between blastocyst morphology and chromosomal status utilizing pre-implantation genetic testing for aneuploidy (PGT-A).
Methods: A single-center retrospective cohort study including 169 in-vitro fertilization cycles that underwent PGT-A using Next Generation Sequencing (2017-2022). Blastocysts were morphologically scored based on Gardner and Schoolcraft's criteria.

Currently, incubators with a time-lapse system are widely used for in vitro embryo production in several species, however, their effect on alpaca embryo development compared to conventional incubators remains unknown. The aim of this study was to compare early in vitro embryo development in alpacas using a time-lapse incubator system versus a conventional incubator. Ovaries were obtained from a slaughterhouse and 1048 cumulus-oocyte complexes (COCs) were collected and in vitro matured for 26 h in either a time-lapse system (n = 542) or a conventional incubator (n = 542).

Background: Growth hormone (GH) could improve the outcomes of fertilization and embryo transfer (IVF-ET) in patients with decreased ovarian reserve (DOR), but which age group will benefit the most has remained controversial. This study aims to explore the outcome of IVF-ET among differently aged patients with DOR treated with GH.
Methods: A total of 846 patients with DOR undergoing IVF-ET from May 2018 to June 2023 at the Reproductive Medicine Center of Sichuan Provincial Women's and Children's Hospital were prospectively enrolled.

Cell fate determination at the chromatin level is not fully comprehended. Here, we report that c-JUN acts on chromatin loci to limit mesoderm cell fate specification as cells exit pluripotency. Although c-JUN is widely expressed across various cell types in early embryogenesis, it is not essential for maintaining pluripotency.
