New protocol of clomiphene citrate treatment in women with hypothalamic amenorrhea.

Objective: To determine if a new protocol of administration of clomiphene citrate (CC) is effective in menstrual cycle recovery in women with hypothalamic secondary amenorrhea.

Design: This was an open-label study.

Patients: Patients comprised a group of eight women with secondary amenorrhea. Interventions. An oral preparation containing CC (50 mg/day) was administered for 5 days followed by a double dose (100 mg/day) for another 5 days, initiated on day 3 after estrogen/progestogen-induced withdrawal bleeding. If ovulation and vaginal bleeding occurred, treatment continued in the two next months with 100 mg/day from day 3 to day 7 day of the cycle.

Main Outcome Measures: Cycle control was evaluated at each visit, when patients recorded bleeding patterns and tablet intake. Data on the intensity and duration of bleeding were collected.

Results: Six patients responded to the first cycle of CC administration, resuming normal menstrual cycles. The other two patients failed to menstruate after the first 10 days of treatment with CC and repeated the same protocol. After the second administration, these two women also had normal menstrual bleeding.

Conclusions: The present data show that this new protocol of CC treatment may be useful to restore normal menstrual cycles in young women with hypothalamic amenorrhea.
