    Twenty-five patients who underwent 48 cycles were enrolled in a prospective, randomized, crossover study.
    Summary · context
    After ovulation induction with recombinant follicle-stimulating hormone (FSH), couples were randomly allocated to a first cycle with a single dose of 0.2 mg of triptorelin or 5,000 IU of urinary hCG to trigger ovulation; if pregnancy did not occur, a second cycle was carried out, and the patient was…
