[Modified Jujing No.2 Decoction for varicocele-induced male infertility]

To investigate the clinical effect of Jujing No.2 Decoction on male infertility induced by varicocele.

We equally randomized 70 male patients with varicocele-induced infertility into a treatment group and a control group, the former treated with modified Jujing No.2 Decoction (1 dose a day, bid) and the latter given Danshen Tablets (4 tablets once, tid) plus Liu Wei Di Huang Wan (8 pills once, tid), both for 3 months. We examined the spermatic veins of the patients by ultrasonography and performed seminal analysis before and after medication.

Compared with the controls, the patients in the treatment group showed significant improvement after medication in sperm concentration (［12.35±2.12］ vs ［18.56±4.16］ ×10⁶/ml, P<0.05), progressively motile sperm (［16.18±6.34］ vs ［24.63±8.51］ %, P<0.05), and morphologically normal sperm (［11.59±5.31］ vs ［14.17±6.02］ %, P<0.05). In the control group, sperm concentration was increased from (12.29±2.07) ×10⁶/ml at the baseline to (13.13±3.13) ×10⁶/ml after medication, progressively motile sperm from (16.13±6.45) % to (20.55±7.30) % (P<0.05), and morphologically normal sperm from (11.62±5.35) % to (12.69±5.77) %. The total effectiveness rate was significantly higher in the treatment than in the control group (71.88% vs 46.67%, P<0.05). The inner diameter of the left spermatic vein was decreased from (0.32±0.05) mm at the baseline to ［0.26±0.05］ mm after medication in the treatment group (P<0.05) and from (0.32±0.03) mm to (0.29±0.04) mm in the control (P<0.05), with statistically significant difference between the two groups after medication (P<0.05).

Jujing No.2 Decoction is effective in the treatment of varicocele-induced male infertility.
