Defective lordosis behavior in cGαo-/- females. (A-C) Lordosis, a sexual stance that denotes female receptivity (A), is severely reduced in cGαo-/- females exposed to both BALB/c (B) and B6 (C) males. A reduction is found in the lordosis quotient using both B6 (t-test: P <0.05) and BALB/c males towards cGαo-/- females (analysis of variance (ANOVA): F3,44 = 5.05; least significant difference (LSD): P <0.05), the percentage of females showing lordosis (ANOVA: F3,44 = 3.44; LSD: P <0.05), but not in the latency to mount females using both B6 and BALB/c stud males (P = 0.33 to 0.47). ns, non-significant.
