  1. The mean ± SEMs for the estradiol, LH and FSH of rats subjected to left or right laparotomy, and left or right ULO at 13:00 h of diestrus-2 day, and sacrificed at 11:00 or 17:00 h on the predicted proestrus day
  2. a p < 0.01 vs. corresponding laparotomy (MANOVA, followed Tukey test)
  3. b p < 0.02 vs. Right ULO (Student “t” test)
