Unilateral sectioning of the superior ovarian nerve of rats with polycystic ovarian syndrome restores ovulation in the innervated ovary
The present study tested the hypothesis that if polycystic ovary syndrome (PCOS) results from activating the noradrenergic outflow to the ovary, unilaterally sectioning the superior ovarian nerve (SON) will result in ovulation by the denervated ovary, and the restoration of progesterone (P4), testosterone (T) and estradiol (E2) normal serum level. A single 2 mg dose of estradiol valerate (EV) t...
متن کاملCompensatory ovarian changes, mast cell distribution and luminal structure changes following unilateral ovariectomy in rats
To follow-up the present study, 40 mature female rats were used. The animals were divided into test,control and sham groups. The rats in the test group were laparotomized and unilateral ovariectomy was done. On the 1st and 2nd met-oestrous after operation, the tissue samples were dissected out and processed for histological study. The intact ovary in the test group underwent a significant (P

متن کاملFactors affecting ovarian compensation after unilateral ovariectomy in gilts.
Two experiments were conducted to identify the temporal limits of an ovarian compensatory response after unilateral ovariectomy (ULO) in gilts and to examine ovarian and hormonal factors that might be related to this response. In the first study, all eight gilts that were unilaterally ovariectomized on d 12, 14 or 16 of an estrous cycle and two of four ULO on d 18 had a significant compensatory...
متن کاملUnilateral or bilateral vagotomy induces ovulation in both ovaries of rats with polycystic ovarian syndrome
BACKGROUND Injecting estradiol valerate (EV) to pre-pubertal or adult female rat results in effects similar to those observed in women with polycystic ovarian syndrome (PCOS). One of the mechanisms involved in PCOS development is the hyperactivity of the sympathetic nervous system. In EV-induced PCOS rats, the unilateral sectioning of the superior ovarian nerve (SON) restores ovulation of the i...
