Abstract

Objective

To evaluate the clinical effectiveness and safety of the Chinese medicine (CM) Qixiong Zhongzi Decoction (芪芎种子汤, QZD) in the treatment of patients with idiopathic asthenozoospermia.

Methods

A total number of 66 patients with idiopathic asthenozoospermia were included and randomly divided into treatment and control groups by SAS-generated code from January 2015 to August 2016, 33 patients in each group. Patients in the treatment group were administered with 150 mL of QZD twice a day, whereas those in the control group were given 1 g of levocarnitine oral liquid twice a day. The two groups received the indicated medication for 12 weeks and were then followed up for 4 weeks. The primary outcome was sperm motility, and the secondary therapeutic indices were sperm volume, density, pregnancy probability, and CM syndrome score. The comparison between groups was carried out at 4, 8 and 12 weeks, respectively. The safety was determined before and after treatment.

Results

(1) Drop-off: 5 cases (7.58%) were lost after treatment (2 from the treatment group and 3 from the control group). (2) Primary outcomes: after 8- and 12-week treatment, the progressive sperms in the two groups were significantly higher than the baseline (all P<0.05); however, the treatment group showed greater improvement compared with the control group at 12-week treatment (22.7% ± 9.0% vs. 14.1% ±8.8%, P<0.05). The increasement of non-progressive grade sperms at both groups was observed at 8- and 12-week treatment with statistical difference (all P<0.05), however, the treatment group showed remarkable improvement compared with the control group at 12-week treatment (38.7% ±14.1% vs. 26.2% ±15.4%, P<0.05). (3) Secondary outcomes: no significant statistical differences were found in semen volume and density (4, 8, and 12-week treatment) and pregnancy probability of patients’ wives (12-week treatment) between two groups (all P>0.05), however, the CM syndrome score of the treatment group significantly declined compared with baseline level at each time points (all P<0.05). (4) Safety: no obvious side reactions were found during the treatment in both groups.

Conclusion

QZD could improve the progressive and non-progressive grade sperm in the treatment of idiopathic asthenozoospermia. It is safe with no obvious side effects.
