Biochemical findings in the ejaculate of men with non-obstructive azoospermia

In men with non-obstructive azoospermia, testicle biopsy can provide isolated sperm which can be used for fertilization of an oocyte. The male seminal plasma was examined for adequate biochemical parameters and then tested as potential diagnostic parameters for prediction of sperm presence in non-obstructive azoospermia. Sperm was obtained by preparation of the testicular tissue. Biochemical parameters in men with found sperm were compared to findings obtained from men without sperm in the testicular tissue. The following parameters were analysed: fructose, lactate dehydrogenase, total acid phosphatase, Zn, K, Na, Cl, pH. No statistically significant differences were found in both groups under study. Biochemical examination of the ejaculate cannot provide any prediction of sperm retrieval in non-obstructive azoospermia.
