Recent developments in the field of human menopausal gonadotropin (hMG) have brought to light significant advancements and trends in fertility treatments and hormone therapy:
A recent review article highlights the increasing use of hMG in infertility treatments, particularly in in vitro fertilization (IVF) protocols. Studies have shown that hMG, especially highly purified forms, has unique attributes that lead to improved outcomes in IVF procedures. The field has empirically chosen hMG as a primary stimulant due to its effectiveness in enhancing the efficiency of IVF procedures.
Research comparing the effects of hMG combined with letrozole to hMG alone for ovarian stimulation in infertile patients undergoing artificial insemination by husband (AIH) has shown promising results. The combination of hMG with letrozole demonstrated significantly higher clinical pregnancy rates and live birth rates compared to hMG alone, indicating the potential benefits of this combined approach in improving pregnancy outcomes for patients with unexplained or mild male factor infertility
.
Studies have delved into determining the optimal dosage of hMG in IVF programs. It has been suggested that an initial hMG dose of 150 IU/day is suitable for IVF programs without gonadotropin-releasing hormone (GnRH) cotreatment, while a dosage of 225 IU/day is recommended for IVF programs with GnRH-a cotreatment. Factors such as age, basal FSH level, and body weight play a role in determining the appropriate hMG dosage to achieve a good ovarian response while minimizing adverse effects on the endometrium and oocytes.
These recent findings underscore the evolving landscape of fertility treatments and hormone therapy, showcasing the potential of hMG in improving outcomes for individuals undergoing assisted reproductive technologies. The increased utilization of hMG in infertility treatments, coupled with research advancements in dosage optimization and treatment combinations, holds promise for enhancing the success rates of fertility procedures and addressing challenges faced by individuals seeking to conceive.
