Modifiable lifestyle factors can have an impact on male fertility, but medical treatments have a limited value in enhancing semen quality. Most treatments are based on assisted fertilisation techniques, rather than treatment of the underlying cause. [onlinelibrary.wiley.com]

It was initially reported in 1993 in cases of obstructive azoospermia and later used for treatment of men with spermatogenic failure. [abdominalkey.com]

Of note, a subset of men within this cohort, patients with normal volume testes (greater than 15 cc) and FSH levels between 10 and 15 IU/L, have a much poorer prognosis, with a retrieval rate of 5.9%. [abdominalkey.com]

Although the prognosis for sperm retrieval is poor for patients with large deletions involving AZF region a or b, the results of Y chromosome deletion analysis cannot absolutely predict the absence of sperm. References 1. [auanet.org]

AZFc micro-deletions have a good prognosis for surgical sperm recovery whereas the prognostic value for sperm recovery in AZFa and AZFb micro-deletions is poor[ 51 ] and such individuals should not be offered surgical sperm retrieval. [onlinelibrary.wiley.com]

Evaluation The evaluation of a patient with azoospermia is performed to determine the etiology, prognosis, treatment options and counseling. [omicsonline.org]

This triggers progressive organ dysfunction, immune system activation and profound metabolic derangements, creating a milieu similar to other chronic systemic diseases and presenting as advanced HF with severely limited prognosis. [worldwidescience.org]
