Cryopreservation of Testes Tissue

If there is no sperm in the ejaculate (Azoospermia), tissue is removed directly from the testes by a percutaneous testes puncture or by open testes biopsy (testes will be excised). Small tissue samples are taken and microscopically analyzed to determine if the tissue contains viable sperm.

If tissue samples contain viable sperm, the sperm can be cryogenically preserved and, if necessary, later unfrozen for use in the ICSI treatment.
