Published: August 2012

Obesity can have detrimental effects on pregnancy rates in natural conceptions and also in women undergoing IVF or intracytoplasmic sperm injection (ICSI). This review summarises the most recent clinical literature investigating whether obesity impacts oocyte quality and early embryo growth. In other tissues, obesity leads to lipotoxicity responses including endoplasmic reticulum stress, mitochondrial dysfunction and apoptosis. Recent reports indicate that lipotoxicity is a mechanism by which obesity may impact oocyte quality.

Effect of Time-Lapse Incubation System on In Vitro Development of Alpaca Embryos.

Reprod Domest Anim

Veterinary Embryology Laboratory, Professional School of Veterinary Medicine, Universidad Nacional de San Antonio Abad del Cusco, Sicuani-Cusco, Peru.

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.

An intelligent decision-making system for embryo transfer in reproductive technology: a machine learning-based approach.

Infertility has emerged as a significant public health concern, with assisted reproductive technology (ART) is a last-resort treatment option. However, ART's efficacy is limited by significant financial cost and physical discomfort. The aim of this study is to build Machine learning (ML) decision-support models to predict the optimal range of embryo numbers to transfer, using data from infertile couples identified through literature reviews.

Ovarian aging is mainly characterized by a progressive decline in oocyte quantity and quality, which ultimately leads to female infertility. Various therapies have been established to cope with ovarian aging, among which exosome-based therapy is considered a promising strategy that can benefit ovarian functions via multiple pathways. Here, we isolated and characterized exosomes derived from ovarian follicular fluid and profiled the differential expression patterns of noncoding exosomal RNAs in young and aged women.

In vitro maturation (IVM) is a form of assisted reproductive technology (ART) applied to obtain mature oocytes in culture. Decline in IVM success rates by age has led consideration of novel approaches based on cellular dynamics. Our aim was to achieve proteostasis in old bovine oocytes from 13 to 16-year-old bovine with a lower potential for fertilization.
