Sexual preference of estradiol treated ovariotomized (OVX+E) females. n = 12 for OVX+E Tph2+/+, n = 12 for OVX+E Tph2−/−.*P < 0.05, **P < 0.01, ***P < 0.001. (A) OVX+E Tph2−/− females sniffed female genitals longer than male genitals. OVX+E Tph2−/− sniffed female genitals longer than their OVX+E Tph2+/+ littermates. OVX+E Tph2−/− sniffed male genitals shorter than their OVX+E Tph2+/+ littermates. (B) Percentage of mice of each genotype that sniffed male genitals more (bouts) or longer (duration) than female genitals. (C) OVX+E Tph2−/− females sniffed male heads shorter than their littermates. OVX+E Tph2+/+ females sniffed male heads longer than female heads, whereas OVX+E Tph2−/− females did not display preference. (D) Percentage of mice of each genotype that sniffed male heads more (bouts) or longer (duration) than female heads. (E) OVX+E Tph2−/− mounted female targets earlier than their OVX+E Tph2+/+ littermates. (F) Tph2−/− females mounted female targets more frequently than their Tph2+/+ littermates.
