The predictive value of serial serum estradiol and serial endometrial volume on endometrial receptivity on assisted reproductive technology cycles

BMC Pregnancy and Childbirth, 2021
Background Diagnosis of endometrial receptivity is still unclear and conflicting. Despite advances in embryo development during assisted reproductive technologies (ART) cycles, the intricate process of implantation is still matter for debate and research.

Endometrial receptivity and implantation require uterine BMP signaling through an ACVR2A-SMAD1/SMAD5 axis

Nature Communications, 2021
During early pregnancy in the mouse, nidatory estrogen (E2) stimulates endometrial receptivity by activating a network of signaling pathways that is not yet fully characterized.

From implantation to birth: insight into molecular melatonin functions [PDF]

, 2018
Melatonin is a lipophilic hormone synthesized and secreted mainly in the pineal gland, acting as a neuroendocrine transducer of photoperiodic information during the night.

In search for an ideal marker of endometrial receptivity: from histology to comprehensive molecular genetics-based approaches

Alʹmanah Kliničeskoj Mediciny, 2019
Background: Despite significant improvements in the efficiency of assisted reproductive technologies (ART) for the past 10 years, proportion of unsuccessful cycles still remains significant and can reach up to 40%. Impairment of embryonic implantation is

Growth Hormone and Endometrial Receptivity [PDF]

Frontiers in Endocrinology, 2019
Administration of growth hormone (GH) during ovarian stimulation has shown beneficial effects on in vitro fertilization (IVF) outcomes. It is generally believed that this improvement is due to the stimulating effect of GH on oocyte quality. However, studies are emerging that show possible positive effect of GH administration on endometrial receptivity,

Peripheral and central mechanisms involved in hormonal control of male and female reproduction [PDF]

, 2016
Reproduction involves the integration of hormonal signals acting across multiple systems togenerate a synchronized physiological output. A critical component of reproduction is the luteinizinghormone (LH) surge, which is mediated by estradiol (E2) and ...

Research progress on non-invasive testing of endometrial receptivity

Frontiers in Reproductive Health
Endometrial receptivity plays a crucial role in the process of embryo implantation and is a key factor affecting the success rate of assisted reproductive technology. Traditional ultrasound assessment of endometrial receptivity has poor accuracy.
