Sexual receptivity quantified in females that approached the male in the four treatment groups, i.e. intact females (SHAM - white), ovariectomized females (OVX - light grey), ovariectomized females treated with testosterone (OVX+T - dark grey) or ovariectomized females treated with testosterone and Vorozole (OVX+T+VOR - black). In the partner preference test (A – experimental female in grey), the mean of crouching responses (expressed as a percentage of male approaches) over sessions performed during the treatment was not influenced by endocrine treatment (B). The mean of male avoidance (expressed as a percentage of male approaches) over sessions performed during the treatment was lower in OVX+T females compared to OVX+T+VOR females (C). (*) p < 0.1, * p < 0.05, ** p < 0.01. p values are adapted with the Bonferroni correction when appropriate.
