Imaging technique to improve the testicular sperm extraction while reducing trauma during surgery

In the middle of Europe nearly every sixth couple of reproductive age is involuntarily childless iAbout 50% of cases are due to male infertility. In about 10% of all infertile men, azoospermia is diagnosed, i.e. no spermatozoa are found in the ejaculate. In this case, testicular sperm extraction (TESE) is performed before starting in vitro fertilization (IVF): Spermatozoa are obtained by cutting a minimum of three tissue samples out of the testes. The localization of the biopsies is routinely determined arbitrarily. Yet, as sperm is not homogeneously distributed in the tissue, the procedure leads to an extraction of sperm in only about 50% of the patients.
