Table 1 Progesterone, testosterone and estradiol levels in control rats and animals treated with anesthesia, ventral or dorsal sham surgery performed at 13:00 h on each day of the estrous cycle and sacrificed 1 h after treatment

From: The acute effects of bilateral ovariectomy or adrenalectomy on progesterone, testosterone and estradiol serum levels depend on the surgical approach and the day of the estrous cycle when they are performed
