title: Seminal parameters of ejaculates collected successively with sixty minute interval in infertile men: effect of combination of prazosin and terbutaline on these parameters.
abstract: Out of 37 infertile men, 33 who were able to give two ejaculates by masturbation successively with a sixty minute interval, were studied. There was no significant change in sperm density in the second ejaculation whereas seminal volume decreased (P less than 0.01) and sperm motility increased (P less than 0.05) significantly. After a seven-day treatment with combination of prazosin (alpha 1-blocker) and terbutaline (beta 2-stimulator), the same successive ejaculates were obtained from only 27 of these patients. In this case sperm density and motility changed insignificantly, whereas seminal volume again decreased (P less than 0.01) significantly. The changes in seminal parameters were not significant between the pre- and post-treatment second ones. In a short-term study there are not any alterations to observe. The favourable results with a long-term treatment, published by Japanese authors, require a confirmation by further studies.
