Advancements in ovarian stimulation drugs now utilize recombinant gonadotrophins like follicle stimulating hormone (FSH) and luteinizing hormone (LH). These modern treatments offer improved patient comfort and potentially reduced risks of ovarian hyperstimulation syndrome.

Area of Science:

  • Reproductive Endocrinology
  • Pharmacology

Background:

  • Historically, gonadotrophins were sourced from human pituitary glands and urine.
  • Current production involves transformed cell-lines, yielding recombinant (r-) follicle stimulating hormone (FSH), luteinizing hormone (LH), and human chorionic gonadotrophin (hCG).

Purpose of the Study:

  • To review the evolution and current status of gonadotrophin preparations for ovarian stimulation.
  • To discuss the potential benefits of recombinant LH (r-LH) and the impact of GnRH analogues on stimulation protocols.

Main Methods:

  • Review of literature on gonadotrophin production and clinical application.
  • Analysis of the properties of recombinant gonadotrophins and their impact on ovarian stimulation protocols.

Main Results:

Related Experiment Videos

  • Recombinant gonadotrophins (r-FSH, r-LH, hCG) are now standard therapies.
  • Highly purified r-FSH may lead to low LH levels, suggesting potential benefit from LH co-administration.
  • r-LH may offer advantages over hCG for ovulation induction due to a shorter half-life, potentially reducing ovarian hyperstimulation syndrome.

Conclusions:

  • Modern ovarian stimulation protocols are more patient-friendly, incorporating gonadotrophin receptor hormone (GnRH)-agonists and antagonists.
  • The development of recombinant gonadotrophins and refined protocols represents significant progress in assisted reproductive technologies.
