GnRH Antagonist Versus GnRH Agonist in Polycystic Ovary Syndrome During in Vitro Fertilization - Embryo Transfer

GnRH (Gonadotropin-releasing hormone) antagonists in IVF (in vitro fertilization) has been accomplished by several randomized controlled trials compared with conventional GnRH agonist long protocol in polycystic ovary syndrome (PCOS) patients. Moreover, there are debating issues that refer to the timing of GnRH antagonist initiation. The purpose of this study is to investigate the laboratory and clinical priority during ovarian stimulation for IVF in patients with PCOS treated with three different protocols.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • PCOS patients (diagnosed as 2003 ASRM(The American Society for Reproductive Medicine)/ESHRE(The European Society of Human Reproduction and Embryology) consensus meeting guideline)
  • age 20-40 years
  • patients who have normal uterus
  • Korean ethnicity

Exclusion criteria

  • patients who have abnormal thyroid function
  • patients who have abnormal prolactin test
  • patients who have diabetes, or Cushing's syndrome, or congenital adrenal hyperplasia, or androgen-producing tumor.
  • Patients who reject informed consent
  • patients who have experience of adverse events for GnRH agonist, antagonist, recombinant FSH(follicle-stimulating hormone).

Treatment and study plan

GnRH antagonist (Cetrorelix)

Drug

In the first arm, cetrotide will be administrated from the first day during stimulation. In the second arm, cetrotide will be administrated from the sixth day during stimulation

Other names: Cetrotide

Conventional GnRH agonist (Triptorelin)

Drug

Patients in the agonist group were administered GnRH agonist started 5 days before discontinuation of the oral contraceptive.

Other names: Decapeptyl

Primary outcomes

  1. number of oocyte retrieved

    Time frame: ovum pick up day, At the point of ovum pick-up, we can count how many oocyte was retrieved. So, almost just after ovum pick-up, outcome measure will be possible.

Secondary outcomes

  1. pregnancy rate

    Time frame: after confirming fetal heart beat via transvaginal ultrasound. Usually 2~4 weeks after ovum pick-up day.
