How often after a vasectomy should a man be tested?

After a vasectomy, a man should typically have a semen analysis about 8 to 16 weeks post-procedure to confirm the absence of sperm. This initial test helps ensure that the vasectomy was successful. Depending on the results, further testing might not be necessary, but some doctors recommend periodic checks if there are concerns or if the man has symptoms. Always follow the specific advice of a healthcare provider regarding follow-up testing.
