Objective:
To explore the clinical effects of sterilization of vas deferens by irrigation in clinic.
Methods:
Eighty-six male patients with voluntary sterilization were divided into control group (usual vasectomy, n=50) and observation group (sterilization of vas deferens by irrigation, n=36). The age, testicular volume, preoperative average concentration of spern, serum testosterone level, recovery duration evaluated by Artificial Obstruction Azoospermia (AOA) and degree of satisfaction were compared between the two groups of patients.
Results:
There were significant differences in recovery duration, degree of satisfaction between the two groups (P<0.05). And there was no significant difference in age ([32.0±5.5]years vs [31.0±6.3]years), testicular volume ([16.0±4.8]mL vs [17.0±4.4]mL), preoperative average concentration of sperm ([39.6±20.2] ×106/mL vs [40.2±22.6] ×106/mL) and levels of blood testosterone ([4.3±0.8]ng/mL vs [4.4±0.8] ng/mL). There was significant difference in patency rate between the two sides of testicular ducts(91.7% vs 83.3%, P<0.05).
Conclusion:
The method of sterilization of vas deferens by irrigation is worth popularizing in clinic.

Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
