[Qilin Pills for obstructive azoospermia after ejaculatory duct reconstruction].

ABSTRACT

OBJECTIVE: To observe the clinical effect of Qilin Pills in the treatment of severe oligozoospermia after microsurgical ejaculatory duct reconstruction for obstructive azoospermia. METHODS: We retrospectively analyzed 75 cases of obstructive azoospermia treated by ejaculatory duct reconstruction followed by administration of Qilin Pills. The patients were divided into a Qilin group (n=42) and a control group (n=33) postoperatively, treated with Qilin Pills and placebo, respectively. After 3 months of medication, we compared the sperm quality between the two groups of patients. RESULTS: After 3 months' treatment, all the patients experienced remarkable improvement in sperm quality (P<0.05). Compared with the controls, the patients in the Qilin group showed dramatic increases in sperm concentration, from (0.57±0.25) and (0.60±0.18) ×106/ml before medication to (2.83±0.59) and (1.72 ±0.52) ×106/ml after medication, significantly higher in the Qilin than in the control group (P<0.05). The percentage of grade a sperm was increased from (5.52±5.97) and (5.30±6.26)% to (11.56±9.96) and (10.27±6.52)%, that of grade a+b sperm from (9.68±8.63) and (8.64±10.10)% to (23.42 ±14.10) and (20.81±14.70)%, and that of morphologically normal sperm from (2.00±1.27) and (2.31±0.94)% to (3.54±2.47) and (3.47±1.33)%, respectively. No statistically significant differences were observed in sperm motility and normal sperm morphology between the two groups after treatment (P>0.05). The total effectiveness rate was higher in the Qilin group than in the controls (88.1% vs 72.7%), but with no significant difference between the two groups (P>0.05). CONCLUSIONS: Qilin Pills are fairly effective in improving the quantity of sperm in obstructive azoospermia patients after ejaculatory duct reconstruction.
