ObjectiveTo investigate the curative effect of Wenyang Zanyu decoction in treating male infertility with kidney yang deficiency. Methods203 cases of kidney yang deficiency male infertility with kidney yang deficien treated in our hospital from January 2010 to June 2016 were selected. They were randomly divided into observation group (101 cases) and control group (102 cases). The observation group was treated with Wenyang Zanyu decoction. The control group was treated with Wuzi Yanzong pill. The two groups were treated for 3 months. The sperm density, the survival rate of sperm, the proportion of (A+B) grade spermatozoa and the rate of sperm malformation before and after treatment were compared between the two groups. ResultsBefore treatment, there was no significant difference in sperm density, sperm survival rate, (A+B) grade spermatozoa proportion and sperm malformation rate between the two groups (P＞0.05). After 3 months of treatment, the sperm density, sperm survival rate and (A+B) grade spermatozoa proportion of the two groups increased significantly, and the rate of sperm deformity was significantly decreased (P＜0.05). The sperm density, sperm survival rate and (A+B) grade spermatozoa proportion in the observation group were significantly higher than those in the control group, and the sperm deformity rate was significantly lower than that in the control group (P＜0.05). ConclusionThe effect of Wenyang Zanyu decoction in treating male infertility with kidney yang deficiency is significant. The clinical curative effect was significantly better than Wuzi Yanzong pill.
