Metroplasty before IVF in women with a T‐shaped uterus: A clinical challenge
International Journal of Gynecology &Obstetrics, EarlyView.Abstract A T‐shaped uterus is a uterine malformation, which can be either congenital or acquired, potentially impairing fertility and increasing the risk of miscarriage. Diagnosis primarily relies on three‐dimensional ultrasound and hysteroscopy. Hysteroscopic metroplasty is the standard surgical intervention aimed at restoring normal uterine anatomy ...

Gene expression analysis of bovine embryonic disc, trophoblast and parietal hypoblast at the start of gastrulation [PDF]
, 2017 In cattle early gastrulation-stage embryos (Stage 5), four tissues can be discerned: (i) the top layer of the embryonic disc consisting of embryonic ectoderm (EmE); (ii) the bottom layer of the disc consisting of mesoderm, endoderm and visceral hypoblast

Endometrial Stromal Cell Senescence: A Non‐Negligible Factor in Recurrent Pregnancy Loss
iMetaMed, EarlyView.As populations age, links between female reproductive aging and infertility are increasingly evident. Cellular senescence, characterized by near‐irreversible cell‐cycle arrest and accumulation of damage, can impair tissue function. In the endometrium, aberrant senescence of endometrial stromal cells (EnSCs) may compromise receptivity, hinder embryo ...

Interdisciplinary Medicine, EarlyView.Organoids and organ‐on‐a‐chips are advancing reproductive system research. In the female reproductive system, applications include cancer organoid models, placental chips, and hormone simulation models. For the male reproductive system, research focuses on drug resistance mechanisms, co‐culture platforms, and infertility studies. These refined in vitro

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Effect of equilibration time on clinical and neonatal outcomes in human blastocysts vitrification
Reproductive Medicine and Biology, 2020 Purpose Prolonged exposure to equilibration solutions may be detrimental to an embryo's developmental potential, whereas a shorter exposure may affect the penetration of cryoprotectants into blastomeres.
