[Recent trends in male reproductive disorders]

There is growing concern about the considerable decline in semen quality and the increase of male reproductive disorders such as testicular cancer, hypospadias and cryptorchidism over the past decades. Such trend has also been manifested itself in the form of increasing demand for assisted reproductive technology in recent year. Concerning the above Skakkebaek has been proposed a hypothesis that there may exist common etiological factors for these male reproductive disorders. He presented a new evidence that male reproductive disorders are symptoms of an underlying testicular dysgenesis syndrome at the workshop "Hormones and Endocrine Disruptors in Good and Water: Possible Impact on Human Health" held in Copenhagen, May 27-30, 2000. In this paper, we review several topics presented in this workshop.
