Patients with male infertility can often present with sperm in the ejaculate that doesn’t move. Sperm must move to find and fertilize eggs during natural conception. These sperm may be fine in every other way, but in this situation, male infertility is the rule. In this interview with CNN, Dr. Turek describes his published invention that was designed to harmlessly “poke” a nonmoving sperm with a weak sugar solution to learn whether the sperm is alive or not. This invention is based on the concept of osmosis in all living cells. If determined to be alive with this technique, these sperm can be used with assisted reproduction to conceive and a couple who bore a child with this technique is highlighted by CNN.
