Objectives: Determine whether ovulation in dystrophic ovaries treated with GnRH agonist followed by GnRH pulses is due to the GnRH pulse or is patient-dependent. SITE. Endocrinology department, CHU Purpan, Toulouse, France.
Methods: Fifteen infertile patients, age range 22 to 35 years, with ovarian dystrophy were given GnRH agonist (Decapeptyl, 3.75 mg IM on day 3 of the cycle). In 5 patients, an IV pulse of GnRH was then given (6 micrograms/90 min).
Statistical analysis: Mann-Whitney U test, corrected chi 2 test.
Results: Ovulation was achieved in 8/15 cases (3/5 with and 5/10 without pulsatile GnRH p = NS) and 3 pregnancies (without pulsatile GnRH). Before treatment LH was higher in patients who had an ovulation.
Conclusion: Ovulation can be achieved after GnRH agonist treatment in patients with dystrophic ovaries, with or without pulsatile GnRH, particularly if the initial LH levels are high.
