A semen analysis evaluates the several key characteristics of a man’s semen quality. It helps evaluate male fertility for those either seeking pregnancy or conversely verifying the success of a vasectomy.
It provides a snapshot of a man’s statistical fertility, usually with respect to the WHO fertility guidelines, at a certain point in time. Whilst it can provide important insights, it cannot help identify causes of male factor infertility.
The two measurement methods available are a home kit or laboratory analysis. The home kit measures just a few characteristics and is very tricky to handle. The results may serve as a starting point, but the home kit cannot replace a full professional laboratory analysis, conducted by fertility specialists.
Semen can be collected by epididymal extraction, masturbation, condom collection or coitus interruptus. Of these methods, masturbation is most widely preferred way. The collection and precise measurement method may significantly influence results.
