Although women have ABR shorter than men, studies with ovarian hormones on auditory brainstem response (ABR) have conflicting reports when it is recorded at different phases of menstrual cycle (MC) in women. This study compared ABR between pre- and postovulatory phases of MC in healthy female volunteers. The ABR wave latencies (WLs) I, II, III, IV, V and inter-peak latencies (IPLs) I-III, III-V, I-V were compared between two phases of MC. The postovulatory had shorter WL V, IPL III-V and I-V than in preovulatory phase. Other WLs and IPLs showed decreasing trend in postovulatory phase. ABR...
