title: [Treatment of male infertility: current situation and problems].
abstract: We evaluated the results of treatment for male infertility in 883 patients who visited our clinic. The efficacy rate and pregnancy rate after varicocele operation were higher than those after drug therapy. Drug therapy was effective only in patients with a sperm count of 10-40 x 10(6)/ml. The percentage of swollen sperm in hypoosmotic swelling test elevated after operation in varicocele patients. The hypoosmotic swelling test seems to be useful to show the improvement of sperm function by treatment.
