Azoospermia is defined as the absence of spermatozoa in the ejaculate after a detailed assessment of the semen and diagnosed in approximately 15 % of the infertile males. In fact, most of them suffer from having nonobstructive azoospermia (NOA)
Y.M. was one of our non-obstructive azoospermic patients. During his first TESE attempt in another center no mature sperm cell was found.
Researchers in Mikrogen Genetic Diagnostic Laboratory identified some seminal markers as indicators of presence, quantity and developmental stage of the sperm cells in the testis of azoospermic men.
In the evaluation of infertile men genomic and proteomic approaches are widely used as screening tools.
The most dramatic insult of a sperm analysis is, of course, azoospermia. This means absence of neither alive nor dead sperm in the ejaculate.
