- In patients with suboptimal semen quality, the traditional Chinese medicine Wuzi Yanzong did not demonstrate a therapeutic effect on semen quality at 3 months.
- The duration and dosage used in this study may be insufficient to improve semen quality in subfertile men. Nonetheless, the pill appears safe for long-term use.
