title: [Development of biological value of sperm in delayed puberty].
abstract: Changes in the biological value of sperm depending on the time of the first ejaculation are presented. A control group included 194 boys with normal puberty in whom a biologic value of sperm was evaluated in dependence of the first ejaculation. In all time points a biological value of sperm was significantly worse in the delayed puberty than that in the control group. Twenty four months following the first ejaculation sperm was not normal in any case whereas in the control group normospermia prevailed in this period of time.
