The AZF region of the Y chromosome plays a major role in spermatogenesis, and it has been reported that patients with azoospermia lack the AZF region of the Y chromosome (deletion).
The AZF area is composed of three areas AZFa, AZFb and AZFc, and it is targeted at all areas by our hospital's examination.
By the presence or absence of deletion of the AZF region by examination and identification of the site, it is possible to predict whether sperm can be collected from the testes of azoospermia by testicular sperm extraction (TESE).
