title: [Study on hypoosmotic swelling test for infertile male patients].
abstract: The hypoosmotic swelling test was done on 74 infertile men, 7 patients who achieved pregnancy by AIH (AIH group) and 10 fertile men and the usefulness of its test was assessed. 1) The rate of total swollen sperm and that of g type swollen sperm from infertile men were significantly lower than rates in the patients in the AIH group and fertile men. 2) There were significant but weak positive correlations between semen analysis (total sperm concentration, motility, motile sperm concentration) and hypoosmotic swelling test results (total swollen sperm, g type swollen sperm). 3) When the cut off value of the rate of total swollen sperm and g type swollen sperm was set at 42% and 14%, respectively, rates were above the cut off value except for g type swollen sperm in patients in the AIH group.
