We have reported a 36% pregnancy rate (eight of 22 transfers) with the transfer of cryopreserved-thawed embryos in patients with anovulatory or irregular cycles following a protocol using pituitary suppression with leuprolide acetate after preparation of the endometrium with transdermal E2 and i.m. P. This protocol is simple, easy to follow, and safe and could be used in future for all patients with cryopreserved pre-embryos.

Background: Both intramural myomas and thin endometrium exert a detrimental influence on the outcomes of assisted reproductive technology (ART). The downregulation of gonadotropin releasing hormone agonists (GnRH-a) is regarded as an effective approach to reducing the size of intramural fibroids and enhancing endometrial receptivity. Consequently, we conducted this study to assess whether the GnRH-a combined with hormone replacement therapy (GnRH-a-HRT) can improve reproductive outcomes in frozen embryo transfer cycles for patients with a thin endometrium (≤7 mm) and intramural fibroids.

The endometrium, the inner lining of the uterus, assumes a crucial role in the female reproductive system. Disorders and injuries impacting the endometrium can lead to profound consequences, including infertility and compromised women's overall health. Recent advancements in stem cell research have opened new possibilities for the treatment and repair of endometrial issues.

Background: Embryo implantation involves two key elements: a good quality embryo and receptive endometrium. Endometrial receptivity abnormalities are known as one of the possible causes of recurrent implantation failure (RIF), especially when the embryo is euploid. This study was aimed to evaluate the impact of age and other clinical factors on endometrial receptivity in women with RIF.

Unlabelled: Endometriosis is a chronic disease characterized by the growth of the endometrium outside the uterine cavity. In response to estradiol, this tissue begins to proliferate and grow, forming lesions and nodules, which can invade the tissues, causing pelvic pain and infertility. The most widely used pharmacological treatment is progesterone, which manages to reduce symptoms, but approximately one-third of patients develop resistance to treatment.

Objective: Successful embryo implantation is contingent upon the intricate interaction between the endometrium and the blastocyst. Recurrent implantation failure (RIF) signifies the clinical challenge of failing pregnancy post-transfer of high-quality embryos, fresh or frozen, in at least three in vitro fertilization (IVF) cycles, often in women under 40 years. Recent studies identify impaired blastocyst maternal tissue communication among recurrent implantation failure causes.
