Contribution of andrological factors to sterility

Male fertility disorders contribute to sterility by inhibiting conception. The prevalence in general, is high, nearly 5% of men are subfertile or infertile. Infertility could be diagnosed in some cases by specific investigations, however, a positive prediction of fertility is not possible. Nearly half of the couples could be treated successfully. It should be recognized, however, that psychosocial assistance is one of the most important tasks of modern reproductive medicine for couples in whom the treatment was not successful.
