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).

Varicocelectomy in patients with azoospermia [PDF]
Archives of Andrology, 1979 The 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.

Imaging of obstructive azoospermia
European Radiology, 1997Obstructive azoospermia represents approximately 10 % of cases of male hypofertility. It is classified according to the volume of ejaculate. When the latter is normal a proximal obstruction is suspected. Scrotal sonography can help to detect dilation of the epididymal head when clinical findings are equivocal.

SummaryThis study evaluated how many patients with azoospermia might have fertility potential using assisted conception techniques. A total of 102 male patients with aioospermia were included in the study. Thirteen patients had sex chromosomal abnormalities. Testicular biopsy performed in the other 89 patients showed incomplete spermatogenesis in 47 of

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.

Increased cancer risk and azoospermia [PDF]
Fertility and Sterility, 2013 TO THE EDITOR: We thank the distinguished author for bringing attention to our work. As Dr. Schlegel points out, a natural conclusion to draw from the manuscript is that a male factor evaluation is of critical importance for a man's reproductive and overall health (1).

Causes of azoospermia and their management
Reproduction, Fertility and Development, 2004Azoospermia may occur because of reproductive tract obstruction (obstructive azoospermia) or inadequate production of spermatozoa, such that spermatozoa do not appear in the ejaculate (non-obstructive azoospermia). Azoospermia is diagnosed based on the absence of spermatozoa after centrifugation of complete semen specimens using microscopic analysis ...

Testicular cytology in azoospermia
Diagnostic Cytopathology, 1993AbstractTwo hundred‐seventy‐five azoospermic mates were subjected to fine‐needle aspiration (FNA) cytologic study of testis with the aim of determining the cause of azoospermia; 534 aspirates from these patients were classified as follows: normal spermatogenesis (162), hypospermatogenesis (mild, moderate, or severe, 226), absence of spermatogenesis ...

Azoospermia is defined as absence of spermatozoa in the ejaculate. It is found in around 15% of men presenting with infertility. The introduction of intracytoplasmic sperm injection in the early 1990s was coupled with major advances in surgical sperm retrieval. This dramatically changed the concept in management of azoospermia patients, giving them the
