Gynecologic surgery for benign disease: Preserving reproductive potential

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Preserving fertility is essential when managing benign gynecologic disorders in reproductive‐aged women. Surgical interventions can impact future fertility, therefore requiring an evidence‐based, individualized approach. The FIGO Committee on Reproductive Endocrinology and Infertility reviewed current literature to develop recommendations for ...

In-vitro Culture with a Tilting Device in Chemically Defined Media During Meiotic Maturation and Early Development Improves the Quality of Blastocysts Derived from In-vitro Matured and Fertilized Porcine Oocytes [PDF]

, 2010
Under physiological conditions, mammalian oocytes and embryos appear to be stimulated not only chemically but also mechanically, such as by compression, shear stress and/or friction force in the follicle and female reproductive tract.

A review of the impact of micro‐ and nanoplastics on female reproduction: What we know and gaps in knowledge

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Micro‐and nanoplastics (MNPs) are breakdown products of plastics, and humans are exposed to these particles through air, water, food, and soil. There is a growing concern that human exposure to MNPs negatively impacts health. In this review we will discuss the potential health impact of MNPs on ovarian function and the hypothalamic–pituitary ...

Is pathological fetal Doppler cerebroplacental ratio (CPR) associated with adverse delivery outcomes in pregnancies complicated by fetal growth restriction undergoing labor induction? A retrospective cohort study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective The optimal delivery approach for fetal growth restriction (FGR) with pathological cerebroplacental ratio (CPR) remains uncertain. This study evaluated the association between isolated pathological CPR (<5th percentile) and delivery outcomes, specifically the rate of cesarean delivery (CD) due to non‐reassuring fetal heart rate ...

Gonadotropin-Releasing Hormone (GnRH) and Its Agonists in Bovine Reproduction I: Structure, Biosynthesis, Physiological Effects, and Its Role in Estrous Synchronization

Animals
GnRH is essential for the regulation of mammalian reproductive processes. It regulates the production and release of pituitary gonadotropins, thereby influencing steroidogenesis and gametogenesis.
