title: Semen abnormalities in artificial insemination donor candidates.
abstract: We screened 43 healthy adult male medical students as potential anonymous donors for the artificial insemination program at our university. Of the candidates 10 had varicoceles (5 bilaterally). Over-all, 34 men (79 per cent) had inadequate semen analyses by 1 or more criteria. Of the men with varicoceles 80 per cent also had abnormal findings. Three abnormalities were discovered most frequently in the semen of men with a normal physical examination and 5 deficiencies were found in those with a varicocele. Problems with semen quality were more common than those of sperm numbers.
