Effect of irrigation of vas deferens on sperm analyses after vasectomy.
70 men were operated for voluntary sterilisation by vasectomy alone and 20 men by vasectomy and irrigation of distal vasa with acid Kystosol solution. Postoperative semen analyses 2 weeks later showed azoospermia in only 2% of cases after vasectomy alone and in 25% of cases following vasectomy and irrigation, and 2 months postoperatively in 44% and 90%, respectively. Non-motile sperm cells in seminal analyses was the most common finding in both series 2 weeks after vasectomy. The problem whether the non motile sperm cells are viable or not is discussed. However, two azoospermic semen analyses must be obtained before sterility after vasectomy can be ascertained.
