[Clinical experience of Hachimijiogan for male infertility patients]

We treated 53 patients for male infertility with TSUMURA - Hachimijiogan given as a daily dose of 7.5 g for 144 days on the average. The sperm density was improved by administration to 10 X 10(6)/ml or more in 22 patients (41.5%) and lowered to 10 X 10(6)/ml or more in only 2 patients (3.8%). The sperm motility was improved by 10% or over in 29 patients (54.7%) as compared with 5 patients (9.4%) in whom it was lowered by 10% or more. The sperm motile efficiency index ( SMEI ) was improved in 40 (75.5%) of the 53 patients. Statistically significant differences were noted in the improvement in sperm density, sperm motility and SMEI . By contrast, there was no difference in semen volume, sperm morphology or sperm agglutination between the pre- and post- treatment periods. During the period of treatment, the wives of 4 patients (7.5%) conceived children. These results suggest that TSUMURA - Hachimijiogan is effective for male infertility to a certain extent and that clinical trials on its use for male infertility may be meaningful.
