Lupron, a brand name for leuprolide acetate, functions as a gonadotropin-releasing hormone (GnRH) agonist. In the context of a frozen embryo transfer (FET) cycle, its primary role is to suppress the body’s natural hormonal production. By downregulating the pituitary gland, Lupron prevents premature ovulation, which is crucial for precisely controlling the timing of the endometrial lining development and embryo implantation.
Utilizing a GnRH agonist provides clinicians with enhanced control over the menstrual cycle during an FET. This controlled approach allows for optimal synchronization between the embryo’s developmental stage and the uterine lining’s receptivity. Historically, achieving this synchronization presented a significant challenge in assisted reproductive technologies. The controlled environment created through hormonal suppression maximizes the likelihood of successful implantation and subsequent pregnancy.
