title: Screening for obstruction of the vas deferens in Nigerian men with azoospermia using the alpha-glucosidase reaction in semen.
abstract: Obstruction of the vas deferens has been screened for, using the alpha-glucosidase reaction in seminal plasma as previously described by Comhaire. Eighteen patients with azoospermia were studied. The result showed positive reaction in 17 patients (95.0%) and only a weak yellow reaction in 1 patient. The results did not corroborate the working hypothesis that the azoospermia was due to obstruction of the vas deferens. The implications of this findings in the management of male infertility in Nigeria are discussed.
