補助生殖医療時代における男性不妊診療の役割.

Around half the cases in need of assisted reproductive technology (ART), for example in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), are caused by male factors. The majority of couples should be encouraged to undergo ART in this era of advanced marriage age, however, treatment of male factors such as varicocele, obstructive azoospermia and endocrine disorders is strongly recommended for couples who want to conceive without ART. Furthermore, accumulating evidence suggests that treatment of male infertility improves ART outcomes, which will be partially explained by improving sperm quality for reducing seminal oxidative stress and sperm DNA fragmentation. The role of urologists regarding male infertility treatment in the era of ART should be classified and focused on the following : 1 ) to treat reversible causes of male infertility, 2 ) to appropriately manage untreatable pathologies, 3 ) to provide suitable sperms for ART, 4 ) to diagnose and treat life-threatening diseases. By cooperating with gynecologists, urologists should effectively evaluate and treat male factors to provide the best outcomes for infertility treatment. [ABSTRACT FROM AUTHOR]
