Male fertility testing after a vasectomy is a normal routine procedure. The test is conducted to verify that the vasectomy procedure worked correctly and that there is no sperm present in the ejaculation fluid. According to research from the US Collaborative Review of Sterilization, nearly 1 in vasectomy procedures results in a subsequent pregnancy. This number is exaggerated to the actual success rate of the procedure. The majority of these pregnancies occur during the first few weeks after the procedure when all of the currently existing sperm have not been expelled.
Yes, vasectomies are carried out on single men in Australia. It does not matter if you have not had any children, however, you must think carefully about vasectomy as the procedure is permanent. A vasectomy usually takes about 30 minutes, and can be done under local or general anaesthetic.

Earlier testing after vasectomy, based on the absence of motile sperm
Patients are advised to keep the sample warm, e. Samples may be sent to the laboratory any working weekday between To maintain the standards of our service, we occasionally require fresh samples for quality control and training. We may use any surplus sample for these purposes.
Metrics details. Little evidence supports the use of any one vas occlusion method. Data from a number of studies now suggest that there are differences in effectiveness among different occlusion methods. The main objectives of this study were to estimate the effectiveness of vasectomy by cautery and to describe the trends in sperm counts after cautery vasectomy. Other objectives were to estimate time and number of ejaculations to success and to determine the predictive value of success at 12 weeks for final status at 24 weeks.
