title: Reduced uterine response to PGF2alpha under oral contraceptives.
abstract: The effect of prostaglandin F2alpha (PGF2alpha) on the nonpregnant human uterus was evaluated in 35 patients. The compound was administered both by intra-uterine and intravenous routes. Two groups of volunteers were studied;fifteen cases who were under oral contraceptives and twenty women with normal ovulatory cycles. The uterus under the influence of oral contraceptives showed a reduced response to local and systemic administration of PGF2alpha at all phases of the menstrual cycle. The implications of these findings in certain physiological and pathological conditions related to reproduction are discussed.
