Male mouse ultrasonic vocalizations and its impact on female mate choice during premating, mating, and postmating. (A) Male USV calls emitted during premating elicit female approach behavior. (B) Number of female approaches is significantly higher when the male sings compared to devocalized males. (C) Male USVs emission during mating leads to an increase in lordosis behavior. (D) Ratio of lordosis is higher in females than received mounts and intromission from males that emitted USVs compared to males that were devocalized. (E) The duration of mounts in devocalized or intact males is not different. (F) Female mice deliver more pups when mated with males that emitted USVs. (G) A significant correlation between the number of male USVs and female deliveries has been found. Panels (B,D,E,G) adapted and reprinted with permission from Asaba et al.
