Testicular Sperm Aspiration for ICSI (TESA)

The Diamond Institute is among the first centers in the world to successfully offer TESA as a part of male infertility services. TESA is a novel method applied to retrieve sperm from the testicles for IVF by ICSI. It allows us to isolate a single sperm out of testicular tissue removed by biopsy. This is of utmost importance for patients with extremely low sperm production and absence of sperm in the ejaculate (azoospermia). The technique is also helpful for men with surgical or congenital blockage of the vas deferens.
