We report on the low incidence of transient fertility in 892 patients who underwent microsurgical vasovasostomy. Of the 892 patients in whom fertile sperm concentrations (as defined by us) developed 2 to 8 months postoperatively 28 later suffered azoospermia or severe oligospermia. The wives of 5 of the 28 patients with such transient postoperative fertility became pregnant before the patients became azoospermic or severely oligospermic again.
