    Summary · context
    The present report investigated the luteal phase in non-conceptual polyfollicular cycles in 26 patients (group 1) receiving a single dose of 0.5 mg leuprolide acetate to induce ovulation and in a control group of patients (n = 26) (group 2) who were given human chorionic gonadotrophin (HCG) (10,000…
    Summary · context
    All of them were normal ovulatory women undergoing gonadotrophin ovarian stimulation because of unexplained infertility or male factor.
    Summary · context
    In both groups of patients two doses of 2500 IU HCG i.m. were given 6 and 10 days after the ovulatory dose of HCG or GnRHa to support the luteal phase.
  2. 02HumanNon-randomized trialEfficacy outcome

    In women undergoing ovarian stimulation, mean progesterone was lower with leuprolide triggering than HCG triggering, without statistical significance.
