Case report. Successive pregnancies in a patient with premature ovarian failure.

A woman, age 28 yr, visited the gynecological endocrine clinic for oligomenorrhea and primary infertility. Serum FSH and LH levels were high and estrogen concentrations were subnormal. In spite of the presence of high and sustained gonadotropin concentrations, resumption of ovarian function with evident ovulation resulted in the first pregnancy after clomiphene therapy. Four years later the patient did not respond to clomiphene but intramuscular progesterone was effective in induction of ovulation, followed by the second pregnancy. The effect of progesterone on hypergonadotropic ovarian failure is discussed.
