    Abstract:
    OBJECTIVE: To evaluate the efficacy of various treatments in abolishing premature luteinization in infertile women over 37 years old who are undergoing ovulation induction. DESIGN: Prospective, nonrandomized study. SETTING: Tertiary care medical clinic. PATIENT(S): Seventeen infertile women >37 years old in whom premature luteinization was detected during their evaluation (pretreatment) cycle. INTERVENTION(S): The patients underwent three consecutive treatment cycles with clomiphene citrate (group A), hMG (group B), and a GnRH agonist plus hMG (group C). MAIN OUTCOME MEASURE(S): Premature luteinization, defined as a progesterone/E2 ratio of >1 on the day of hCG administration. RESULT(S): Fifteen (88%) of the 17 patients in group A and 13 (76%) of the 17 patients in group B demonstrated premature luteinization. In contrast, only 1 (6%) of the 17 patients in group C had a progesterone/E2 ratio of >1 on the day of hCG administration. The mean (+/-SD) E2 level on the day of hCG administration was significantly higher in group C (1.236 +/- 772.7 pg/mL) than in group A (214.02 +/- 104.46 pg/mL) or group B (412.5 +/- 337 pg/mL). CONCLUSION(S): Pituitary desensitization with a GnRH agonist in conjunction with hMG may be of benefit for older infertile women who demonstrate early luteinization in their first evaluation cycle.
