Medroxyprogesterone Acetate for Abnormal Uterine Bleeding Due to Ovulatory Dysfunction: The Effect of 2...

BACKGROUND Abnormal uterine bleeding (AUB) lowers the quality of life of women. This study attempted to determine which treatment protocol of medroxyprogesterone acetate (MPA), 15 vs 10 day-administration in a luteal phase, provides better outcomes in women with ovulatory dysfunction-related AUB (AUB-O). MATERIAL AND METHODS The study included a total of 52 patients with AUB-O: Women in Group A were given MPA between days 11 and 25 of the menstrual cycle (15-day protocol), whereas women in Group B were given MPA between days 16 and 25 (10-day protocol). Outcomes were compared between the 2 groups. RESULTS Women in group B, compared with those in group A, more often showed regular menstrual cycles and decrement of AUB. In group B, 3 cycles of treatment were sufficient to achieve AUB-stop (p<0.05). Post-treatment hemogram parameters and surgical treatment requirements were not different between the 2 groups. CONCLUSIONS In the second half of the cycle/predicted luteal phase, 10-day cyclic use of MPA (the group B) better regulated the menstrual cycle and more frequently stopped AUB-O.
