[Treatment of oligospermia/asthenozoospermia patients by three different Chinese medical principles: a randomized...

To assess the efficacy and safety of three different Chinese medical principles in treating patients with male infertility (oligospermia/asthenozoospermia).

Totally 128 patients with male infertility were classified into 3 groups, i.e., Shen-essence deficiency syndrome, Pi-Shen deficiency syndrome, Shen-deficiency blood-stasis syndrome. They were assigned to the Chinese medical treatment group (96 cases) and the Western medical treatment group (32 cases) by stratified randomization in the ratio of 3: 1. Those in the Chinese medical treatment group were treated with Chinese drugs for Shen invigorating and blood activating, Shen invigorating and Pi supplementing, Shen-qi benefiting. Those in the Western medical treatment group were treated with Clomifene (at the daily dose of 25 mg per day, once daily). Three months consisted of one therapeutic course. The parameters of semen, the pregnancy rate, and adverse reactions were observed.

Totally 24 patients dropped out in the two group, 17 in the Chinese medical treatment group (9 patients of Shen deficiency blood stasis syndrome, 5 of Shen-Pi deficiency syndrome, and 3 of Shen-essence deficiency syndrome) and 7 in the Western medical treatment group. Compared with before treatment, there was no statistical difference in the improvement of semen amount at 3 months after treatment between the two groups (P > 0.05). There was statistical difference in the improvement of semen density, class A semen, class A +B semen, and 1-h activity ratio (P < 0.05). The improvement was most obvious in Shen deficiency blood stasis syndrome, followed by Shen-Pi deficiency syndrome and Shen-essence deficiency syndrome. The improvement was the weakest in the Western medical treatment group. There was no statistical difference in the improvement of semen amount, semen density, class A semen, or 1-h activity ratio at 3 months after treatment between the two groups (P > 0.05). Best effect was obtained in improving class A + B semen quality in patients of Shen deficiency blood stasis syndrome, showing statistical difference when compared with the other two syndrome types and the Western medical treatment group (P < 0.05, P < 0.01). No obvious adverse reaction occurred in the two groups during the treatment course.

Shen invigorating and blood activating method could improve the semen density and semen activities, and it was superior to other therapeutic methods.
