Brief Summary:
This randomized controlled trial aims to evaluate whether supplementation with exogenous luteinizing hormone (LH) can improve embryo quality in patients undergoing in vitro fertilization (IVF) with a long gonadotropin-releasing hormone agonist (GnRH-a) protocol who have excessive suppression of LH. Eligible participants will be randomly assigned to receive either exogenous LH supplementation or standard care. The primary outcome is embryo quality, and secondary outcomes include pregnancy rates and safety assessments. The study is conducted at Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University.
Detailed Description:
Excessive suppression of luteinizing hormone (LH) during ovarian stimulation with a long gonadotropin-releasing hormone agonist (GnRH-a) protocol has been associated with suboptimal follicular development, impaired oocyte maturation, and reduced embryo quality. LH plays a critical role in the final stages of folliculogenesis, steroidogenesis, and ovulation, and its deficiency during controlled ovarian hyperstimulation may adversely affect the developmental competence of oocytes.
This randomized controlled trial is designed to evaluate whether supplementation with exogenous LH can improve embryo quality in patients undergoing in vitro fertilization (IVF) with excessive LH suppression during a long GnRH-a protocol. Eligible participants are women meeting predefined hormonal suppression criteria prior to or during stimulation. Participants will be randomly assigned to receive either exogenous LH supplementation in addition to standard ovarian stimulation or standard care without LH supplementation.
The primary endpoint is the proportion of high-quality embryos obtained per cycle. Secondary endpoints include clinical pregnancy rate, implantation rate, live birth rate, and safety outcomes such as incidence of ovarian hyperstimulation syndrome (OHSS) and adverse events.
The study aims to provide high-quality evidence to guide the optimal management of patients with profound LH suppression during controlled ovarian stimulation. Findings from this trial may contribute to refining stimulation protocols and improving reproductive outcomes in assisted reproductive technology (ART).
