Ovulation rate in rats with LSVN, RSVN or BSVN. Percent of ovulating rats of rats injected with vehicle (Vh) or estradiol valerate (EV) at day 10 of life, with sham-surgery (sham) or unilateral (LSVN or RSVN) or bilateral vagotomy (BSVN) at day 24 of life, sacrificed at day 90–92 of life. The numbers at the base of the bars indicate the number of ovulating animals/number of treated animals. a p < 0.05 vs. Vh sham; b p < 0.05 vs. EV sham (Xi2 test).
