Hormonal treatments for infertility have evolved significantly over 100 years, moving from early methods to advanced recombinant gonadotrophins and GnRH analogues for improved ovarian stimulation.

Area of Science:

  • Reproductive Endocrinology
  • Infertility Treatments
  • Medical History

Background:

  • Infertility treatments, including ovarian stimulation, have a century-long history.
  • Early treatments involved radiation therapy, with cancer risks identified later.
  • Hormonal stimulation initially used non-human (PMSG) and human pituitary (HPG) gonadotrophins.

Observation:

  • Pregnant Mare Serum Gonadotrophin (PMSG) caused antibody formation, limiting its use to one cycle.
  • Human Pituitary Gonadotrophin (HPG) was effective but withdrawn due to Creutzfeldt-Jakob disease links.
  • Human Menopausal Gonadotrophin (HMG) preparations had batch inconsistency due to urinary proteins.

Findings:

  • Recombinant gonadotrophins, produced in CHO cell lines, offer standardized and consistent preparations.

  • Long-acting gonadotrophin formulations represent a recent advancement.
  • Gonadotrophin-releasing hormone (GnRH) analogues and antagonists enhance ovarian stimulation protocols.

    • Implications:

    • The evolution of gonadotrophins has led to safer and more effective infertility treatments.
    • Advancements in hormonal therapy have improved the efficacy and administration of ovarian stimulation.
    • Continued innovation in reproductive medicine offers better outcomes for patients with infertility.
