Genotype differences in female sexual behaviors. Female mice were tested 4 consecutive days, and the data were sorted based on the days of estrous cycle. Day 1 represents the day of behavioral estrus. Overall, βERKO female mice showed higher levels of receptivity compared with WT female mice as demonstrated in the lordosis quotient (A), the percent of proceptive/still posture (B), and the receptivity score (C). They especially showed higher levels of sexual behavior on the day after behavioral estrus (day 2). *, P < 0.05 vs. WT.
