Oligo/Azoospermia in Nigeria [PDF]
Archives of Andrology, 1989 Oligo/azoospermia contributes significantly to infertility in male Nigerians, being responsible for most of the problem. By definition, it would appear that the criteria for the diagnosis of this problem in Nigerians should be sperm density below 10 million/ml, total sperm ejaculate below 25 million, motility below 40%, and normal forms below 40% in ...

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 ...

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 ...

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 ...

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.

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).

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.

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.

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
