  • Title: Asymmetric secretion of principal ovarian venous steroids in the primate luteal phase.
    Author: Marut EL, Hodgen GD.
    Journal: Steroids; 1982 Apr; 39(4):461-9. PubMed ID: 7179354.
    Abstract:
    We have characterized the degree of asymmetry of ovarian steroid secretion in the luteal phase of the menstrual cycle in rhesus and cynomolus monkeys. Femoral blood levels of FSH, LH, progesterone, estradiol and 17-hydroxyprogesterone were determined. In addition, laparotomies were performed in the early, mid or late luteal phase to facilitate localization of the corpus luteum and collection of ovarian venus blood. We conclude that: 1) the ovary bearing the active corpus luteum contributes virtually all of the progesterone entering peripheral circulation in the luteal phase; 2) the ipsilateral ovary secretes more 17-hydroxyprogesterone one than the contralateral one, although both are active in the luteal phase; and 3) the asymmetrical secretion of estradiol was manifest only in the early and mid-luteal phase, with ovarian symmetry being reestablished in the late luteal phase.
