[Infertility after mumps orchitis (author's transl)].

Mumps orchitis is the most frequent complication of mumps in young men. 11 of 23 patients were followed up, 9 answered a questionnaire. 11 spermiograms were available. 6 patients, 3 of them after bilateral mumps orchitis, had children. Although some severe fertility disturbances were seen, no case of real infertility was found. The rate of atrophy was 53%. 12 patients remained at least subfertile (60%), 5 of them after bilateral mumps orchitis, 3 patients were almost infertile after bilateral mumps orchitis. Patients with corticosteroid therapy showed better results at followup examinations than the others, although no significance was found (alpha greater than 0.05).
