title: A new non-hormonal antifertility drug DL-204: II. Effect on testicular hyaluronidase and gamma-glutamyl transpeptidase in male rats.
abstract: Effects of DL-204, 2-(3-ethoxyphenyl)-5,6-dihydro (5,1-a)-isoquinoline, a non-hormonal antifertility drug on testicular hyaluronidase and gamma-glutamyl transpeptidase levels, biochemical markers for testicular function, were evaluated in male rats. Treatment of 21-day-old rats with DL-204 for 7 or 15 days produced cryptorchid condition. Testicular hyaluronidase and gamma-glutamyl transpeptidase levels reveal that DL-204 acts on the testes, possibly in two ways; one, by reducing the gonadotropin levels thereby reducing the levels of androgens as reflected by reduced accessory reproductive organ weights and, secondly, by a direct action on the testes. Thus, we conclude that DL-204 is acting as an antispermatogenic agent, possibly acting in more than one way on the testes.
