Abstract
Hemiovariectomized rats were randomly assigned to 1 of 5 groups: controls, 6-hydroxydopamine (6-HD)-treated, abdominal vagotomy, 6-HD-treated plus abdominal vagotomy and pelvic parasympathectomy. 15 days later all animals were sacrificed and the amount of compensatory ovarian hypertrophy (COH) was calculated. Vagotomy and vagotomy plus 6-HD treatment interrupted estrous cycles and significantly decreased COH. Vagotomized rats with both ovaries intact had disrupted estrous cycles but ovarian weights were not affected. In a subsequent study, rats in estrus were sham-operated, unilaterally ovariectomized (ULO), vagotomized, or vagotomized + ULO, and serum levels of LH and FSH were determined at 5 and 24 h. ULO caused a significant (p
