Abstract

Regulation of the physiological process that ends with ovulation is modulated by neural information linking the ovaries with the central nervous system. We evaluated the effects of unilateral mechanical stimulation of the ovarian pedicle of the rat and hemiovariectomy performed on each day of the oestrous cycle on ovulation rate and monoamine and metabolite concentration, as well as neural activity in the preoptic anterior- hypothalamic area (POA-AHA) on the morning of oestrus day. Unilateral stimulation of the left ovarian pedicle on dioestrus 2 blocked ovulation in all the animals without altering the vaginal cornification rate. The norepinephric neural activity in the POA-AHA was below the sensitivity of the detection method. Hemiovariectomy reduced both ovulation and vaginal cornification rate when performed on dioestrus 1 and dioestrus 2, despite the presence of the remaining ovary. These results support the idea that the ovarian innervation participates in the control of mechanisms regulating ovulation. Med Sci Res 26:545-547 (C) 1998 Lippincott Williams & Wilkins.
