Oocyte quality, a critical determinant of female reproductive potential, experiences a progressive decline with age, largely driven by the cumulative effects of oxidative stress and mitochondrial dysfunction. This review thoroughly …
What is the optimal timing of progesterone exposure to achieve live births for day-6 blastocysts in artificial frozen-thawed embryo transfer (FET) cycles?
Background: Endometriosis is a major cause of female infertility. It significantly impacts oocyte quality and embryonic development. The condition's pathophysiological mechanisms are multifactorial. However, they are believed to be reflected …
Infertility affects one in six individuals worldwide despite the advancement of assisted reproductive technologies. Successful embryo implantation is the first step of pregnancy, which relies on the establishment of a …
Decidualization of human endometrial stromal cells (ESCs) precedes the successful implantation of a human embryo. Improper decidualization has been reported in numerous conditions associated with infertility including endometriosis. Multiple pathways, …
The origin of ectopic gynecologic lesions has been debated since 1927, when Sampson first proposed retrograde menstruation as the underlying cause of endometriosis. Reproduction in mammals is an unusually permissive …
The objective of this study is to evaluate the effectiveness of prolonged GnRH agonist (GnRH-a) suppression combined with letrozole and intensive luteal phase support in a patient with severe adenomyosis …
Endometriosis is a chronic hormone-responsive disorder linked to infertility, usually characterized by the presence of ectopic endometrium in the pelvis that disrupts local homeostasis. Advances in single-cell "omic" methods have …
Three-dimensional (3D) organoid and co-culture models have emerged as transformative tools for studying human endometrial function, implantation, and placental development, overcoming key limitations of animal and two-dimensional in vitro systems. …
Progesterone plays a pivotal role in implantation and ongoing pregnancy. In the context of assisted reproductive technology (ART), and in particular frozen embryo transfer (FET), increasing evidence suggests that serum …
