[Catamnestic studies in sub- and infertile couples]

310 infertile couples have been studied retrospectively over a 15-year period from the andrological and gynaecological view. Teratozoospermia in men and tubal disturbances in women respectively turned out to be the most common causes. Isolated male infertility was found in 33%, that of the female partner in 19%. Both partners were involved in 40%. 93 women (30%) finally gave birth to a child after successful treatment.
