Mean (±SEM) Lordosis quotients (LQs) were determined on sexual receptivity tests conducted after 6 days of estradiol benzoate (EB; 2.0 or 10.0 µg/day; Test Day I), and again following 3, 6, 14, and 15 days (Test Days II, III, IV, and V, respectively) of continued EB treatment concurrent with dihydrotestosterone propionate (DHTP; 7.5 mg/kg) or the oil vehicle or 5α-androstane-3-α, 17β-diol (3α-Adiol; 3.75 mg/kg) or the propylene glycol (PG) vehicle. On Day 15 (Test Day V), all female rats received progesterone (1.0 mg/rat) 4 h before testing.
N ≥ 7 per group.
* P < 0.05 vs. all other groups on the same Test Day
# P < 0.05 vs. both EB + oil/PG treated groups on same Test Day
