While there’s plenty we don’t know, we have learned a lot about male fertility and reproduction over the past few decades. One of the most exciting areas of research and advancement has been in the management of male fertility concerns. Nonobstructive azoospermia was at one time considered difficult or impossible to treat, yet now, many men with no detectable sperm in their semen have become fathers. Today, there are several sperm extraction techniques available to these men, but most are invasive. As such, there has been a need for minimally invasive diagnostics to see whether sperm can be found in the testes.
