Purpose: To measure the estradiol (E2) and progesterone levels on day of human chorionic gonadotropin (hCG) and to assess follicular development, pregnancy rates and IVF-ICSI outcomes comparing gonadotropin releasing hormone (GnRH) agonist and antagonist protocols.
Methods: A total 195 women were included in the study. The patients were treated with agonist or antagonist protocol according to the clinician's and patient's preference. GnRH agonist and antagonists were administered to 77 and 118 patients, respectively.
Results: Retrieved oocyte number (RON), metaphase two oocyte number (MON), E2 and progesteron levels on day of hCG, and fertilization rate were significantly higher in agonist group than antagonist group (p < 0.05). Implantation rate (IR), clinical pregnancy rate (CPR), and ongoing pregnancy rate (OPR) were significantly higher in antagonist group than agonist group (p < 0.05). However, there was no significant difference between both groups in relation with total follicle stimulating hormone (FSH).
Conclusion: GnRH agonist treatment seems to be associated with higher serum E2 and progesterone levels and resulted in lower pregnancy rates than antagonist treatment.

Background: Early menarche is associated with both physical and psychosocial problems. Based on psychological and physical health considerations, for girls with early menarche, some parents and physicians may elect to use gonadotropin-releasing hormone agonists (GnRHa) to delay menstruation. This study aimed to explore the effects of GnRHa treatment on the final height of girls with early menarche and build the models to predict the final adult height (FAH).

Purpose: Uterine fibroids are the most common pelvic tumors in women, representing the primary indication of hysterectomy. Gonadotropin-releasing hormone (GnRH) antagonists represent a new therapeutic option for premenopausal women. The aim of this review is to evaluate the efficacy and safety of GnRH antagonists in the treatment of uterine fibroids (size reduction and symptom control).

Background: Prostate cancer treatment involves hormonal therapies that may carry cardiovascular risks, particularly for long-term use. Gonadotropin-releasing hormone (GnRH) antagonists, such as degarelix, may offer advantages over agonists, but comprehensive comparative cardiovascular outcomes are not well established. This study aimed to systematically review and analyze the cardiovascular safety profiles of degarelix compared to those of traditional GnRH agonists, providing critical insights for optimizing treatment strategies.

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.

Context: Progestins have recently been used as an alternative for gonadotropin-releasing hormone (GnRH) analogues to prevent premature luteinizing hormone surge due to the application of vitrification technology. However, the long-term efficacy and safety of a progestin-primed ovarian stimulation (PPOS) regimen, including oocyte competence, cumulative live birth rate (LBR), and offspring outcomes, remain to be investigated.
Objective: To compare cumulative LBR of preimplantation genetic testing (PGT) cycles between a PPOS regimen and GnRH analogues.
