A team of Indian researchers has identified a crucial genetic mechanism that allows pregnancy to begin, marking a major advance in reproductive biology. The study, published in Cell Death Discovery, reveals how two genes work in opposition to regulate the moment an embryo successfully implants into the uterine lining. Scientists from NIRRCH in Mumbai, IISc in Bengaluru and BHU in Varanasi collaborated to investigate why the uterus becomes receptive only for a brief window, and what determines
