Adenosis occurred in transplanted C57BL and BALB/c mice MÃ1⁄4llerian-derivedreproductive tract regions, cervix, and/or fornix (FX), and middle vagina but never in the urogenital sinus-derived portion of the vagina, after a 1-mo exposure to endogenous ovarian hormones or exogenous estradiol (E2). Grafts in ovariectomized hosts did not exhibit adenosis, confirming its depend ence on estrogen. C57...

POWERS, J. B. AND J. MOREINES. Progesterone: examination of its postulated inhibitory actions on lordosis during the rat estrous cycle. PHYSIOL. BEHAV. 17(3) 493-498, 1976. Three experiments tested whether the inhibitory effects of progesterone could be of physiological significance in regulating the duration of behavioral estrus in female rats. In animals displaying 5 day estrous cycles, a sec...

A workshop on the epidemiology of ovarian cancer was held at the National Institutes of Health, Bethesda, Maryland, on September 30, 1 991 . The goals of the workshop were to address: (a) reproductive factors; (b) exogenous hormone use; (c) diet, life style, and health practices; (d) tumors of low malignant potential and nonepithelial germ cell ovarian tumors; (e) prospective studies; (I) deter...

background: the ability of the ovary to respond to exogenous gonadotrophin stimulation and development of several follicles is essential in assisted reproductive technology. neither age and regularity of menses nor follicular phase fsh and estradiol concentrations are reliable predictors of ovarian response. day 3 serum inhibin-b level, during induction ovulation, has been proposed as a predict...

background: one the main aspects of an in vitro fertilization (ivf) cycle is to avoid any possible systemic damage to women undergoing to a controlled ovarian hyperstimulation (coh). the aim of this work is to evaluate renal and hepatic function blood tests in patients undergoing controlled ovarian hyperstimulation during ivf cycles. materials and methods: all patients received a long stimulati...

It is known that the follicular selection and final stages of follicular maturation are equal if not more dependent on low circulating levels of LH.In addition to stimulating production of thecal androgens as substrate for estrogen synthesis, LH stimulates granulose cell via LH receptors induced by FSH and estrogen in larger but not smaller follicles. The data from numerous assisted reproductio...
