Does a natural cycle result in higher clinical pregnancy rates (CPR) with foetal heartbeat compared to an artificial cycle for frozen-thawed embryo transfer (FET) preparation in ovulatory women?
Endometriosis and adenomyosis are estrogen-dependent inflammatory conditions frequently associated with impaired fertility. Although progesterone resistance at the tissue level is well documented, it remains unclear whether these conditions are associated …
What is the optimal timing of progesterone exposure to achieve live births for day-6 blastocysts in artificial frozen-thawed embryo transfer (FET) cycles?
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 …
Previous studies have shown that due to the presence of endometrium progesterone resistance in patients with endometriosis, it is considered that higher levels of progesterone may be required to achieve …
To investigate the effects of pretreatment with long-acting gonadotropin-releasing hormone agonist (GnRH-a) before frozen-thawed embryo transfer (FET) on pregnancy outcomes in patients after minimal-mild (stages I-II) peritoneal endometriosis surgery. A …
Adenomyosis can lead to infertility and failure of in vitro fertilization. Limited evidence suggests that the use of long-term treatment with gonadotropin-releasing hormone (GnRH) agonists followed by frozen-thawed embryo transfer …
