Is GnRH Agonist Plus Letrozole a Better Choice Than GnRH Agonist Alone in Adenomyosis Cases Undergoing Frozen Embryo Transfer?

Overview

Purpose of the Study: To compare the effectiveness of GnRH agonist downregulation alone versus GnRH agonist combined with letrozole in improving pregnancy outcomes in women with adenomyosis undergoing frozen embryo transfer (FET). Research Question: Is the combined use of GnRH agonist and letrozole more effective than GnRH agonist downregulation alone in achieving better ongoing pregnancy rates in adenomyosis cases undergoing FET? Hypothesis: Null Hypothesis (H₀): The combined use of GnRH agonist and letrozole is not more effective than GnRH agonist downregulation alone in achieving a higher ongoing pregnancy rate in adenomyosis cases undergoing FET. Study Outcomes: Primary Outcome: Ongoing pregnancy rate at 12 weeks of gestation.

Interventions

  • Drug GnRH agonist downregulation
    Triptorelin Acetate 3.75mg for two consecutive dosage at 30 days interval
  • Drug GnRH agonist and Letrozole
    Triptorelin Acetate 3.75mg for two consecutive dosages at 30 days interval) + Letrozole (5 mg once daily for a total of 21 days during the second depot - letrozole stops when Estrogen priming starts

Primary outcome measures

  • Ongoing pregnancy rate [Time frame: 12 weeks of gestation]
Secondary outcome measures (6)
  • Implantation Rate [Time frame: 4 weeks after embryo transfer]
  • Chemical Pregnancy rate [Time frame: 4 weeks after embryo transfer]
  • Biochemical loss rate [Time frame: 4 weeks after embryo transfer]
  • 1st trimester loss [Time frame: 12 weeks of gestation]
  • 2nd trimester loss [Time frame: 20 weeks of gestation]
  • Live Birth Rate [Time frame: Post delivery after completion of 20 weeks of gestation]
