Orgasmic frequency and plasma testosterone levels in normal human males

Arch Sex Behav. 1976 Mar;5(2):125-32. doi: 10.1007/BF01541869.


Twenty males participated in a 2-month study examining the relationship between 8 a.m. plasma testosterone levels and orgasmic frequency. Within subjects, higher levels of testosterone are associated with periods of sexual activity. Over subjects, however, the direction of the relationship is reversed. Mean testosterone levels were higher for sexually less active individuals.
