Varicocelectomy in patients with azoospermia
Archives of Andrology, 1979The results of surgical treatment of 33 men with azoospermia and varicocele are presented. Microscopic examination of a testicular biospy revealed the Sertoli-cells-only syndrome in nine subjects while degenerative changes in the seminiferous tubules of one or both testes were present in another six persons.

By using a detailed history and physical examination, endocrinologic studies, and, in some cases, testicular biopsy, we assign azoospermic men to three pathogenic groups: pretesticular, testicular, and posttesticular. This and further subclassification allow physicians to provide prognostic information.

Current Opinion in Urology, 2000
Nonobstructive azoospermia (NOA) remains a challenging condition in reproductive medicine to manage. The genetic basis of NOA related to partial deletions of the Y-chromosome has been intensely investigated. Such information is of prognostic value and allows more insightful genetic counseling of couples who opt for assisted reproductive technology ...

Obstructive azoospermia accounts for 40% of azoospermia and results from obstruction of the excurrent ducts (due to many causes) at any location between the rete testis and the ejaculatory ducts. The diagnosis of obstructive azoospermia (OA) requires a stepwise approach to differentiate it from nonobstructive OA and to formulate management options ...

Summary— Azoospermia in the presence of a normally funcitioning testis and a normal vasogram has been thought to be due to an obstruction in the epididymis between the body and the head. However, bypass operations have been singularly unsuccessful except when there was evidence of past inflammation causing ...

Role of Genetics in Azoospermia
Urology, 2011To review established genetic causes of azoospermia, the most severe form of male infertility, and help clinicians, scientists, and infertile couples considering assisted reproductive technologies (ART) to understand the complexity of the disorder and to maximize the chances of having a healthy infant through proper counseling and treatment.An initial ...

Azoospermia is defined as the complete absence of sperm in the ejaculate even after centrifugation. With a prevalence of 1 % among the general male population and 10-15 % among infertile men, it can be classified in two large groups: Obstructive and non-obstructive azoospermia (OA and NOA).
