Semen abnormalities in artificial insemination donor candidates.
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.
