Androgen-treated lizards (OVX plus T) were injected ip either with 0.9% saline or 1 mg/kg DOI (n = 8 per group), and receptivity was noted before (before drug), 20 min after injection (20 min after drug), or 50 min after injection (50 min after drug). Previously nonreceptive OVX plus T lizards demonstrated receptivity 20 min after DOI injection and returned to a nonreceptive state 50 min after injection (P < 0.001). X² = 12.713; P < 0.001.
