SummaryAfter a control estrous cycle, 10 mg PGF2α was deposited in the uterus in six mares (300-500 kg; 3-20 yr) at 7-9 days after ovulation. Blood plasma progesterone fell from 13.6 to 5.8 ng/ml within 12 hr and to 0.9 ng/ml at 48 hr after PGF2α,

Umbilical arterial and venous blood, and fetal testes were taken from 38 bovine fetuses at 90, 180 or 260 days of gestation. Concurrently blood also was taken from the jugular, and from the uterine artery and vein of the dams. Testosterone and andros

After an intra-arterial injection of 10 mug GnRH into four bovine male fetuses, serum LH increased (P less than 0.01) 2-fold by 15 min and plateaued at approximately 11 ng/ml from 60 to 180 min. After GnRH in six female fetuses, LH increased (P less

In a Latin Square design, each of 6 heifers was given (im) 5, 10 and 15 mg PGF20 during diestrus during three consecutive estrous cycles. Then the uterus and cervix were removed. Thirty to 45 days after surgery, each hysterectomized heifer was given
