[Sexual activity of infertile couples]

Sexual activity, i.e., the weekly number of sexual intercourses was measured on the basis of data obtained through a separate personal interview of males and females in the study group of infertile couples and as in the control group of couples who just decided to have a baby. The sexual activity of infertile couples was higher (just by 1) in a comparison with the figure of control couples and this difference was significant in all age groups. This phenomenon was explained mainly by the higher sexual activity of infertile males. Thus, the sexual activity of males with very low sperm count (< 5 million/ml) was higher than that of males with normozoospermia in the infertile study group. There was a small group (about 6%) with sexual hyperactivity (> or = 7 sexual intercourses per week) in the infertile group.
