VasektomieVerifikation

VasektomieVerifikation, or post-vasectomy semen analysis, is the medical process used to verify that a vasectomy has achieved sterility. It involves analyzing semen samples after the procedure to determine whether sperm are still present. The goal is to confirm that the patient can discontinue contraception and avoid unintended pregnancies.

The verification typically begins several weeks after surgery and depends on the patient’s ejaculation frequency. A first sample is usually collected after about 6 to 12 weeks or after around 20 ejaculations, whichever occurs first. If sperm are detected, additional samples are collected at intervals until results show no sperm or only very low counts. Most guidelines require two consecutive analyses showing azoospermia (no sperm) or cryptozoospermia (sperm detected only after concentration).

Interpretation and decision-making rely on the results of semen analyses. A result with no detectable sperm, or with only rare, non-motile sperm after concentration, is considered evidence of sterility for practical purposes. If any sperm are found in a sample, the testing interval is typically repeated, and contraception continues until two consecutive negative results are obtained.

Practical notes include adherence to proper semen collection and laboratory procedures, as well as the understanding that residual sperm may persist for months in some individuals. PVSA cannot guarantee immediate sterility, and decisions about stopping contraception should follow the confirming test results and medical guidance.
