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

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 ...

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 ...

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.

Secondary azoospermia after vasovasostomy
Fertility and Sterility, 2004To determine the frequency of secondary azoospermia after microsurgical vasovasostomy and to determine what factors increase the risk of its occurrence.We performed a retrospective review of three surgeons' experience. Patency was defined as the presence of sperm in at least one postoperative semen sample.

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 ...

The lack of sperm in the ejaculate is the hallmark of azoospermia. 15% of male infertile individuals have azoospermia. Obstructive azoospermia (OA) and non-obstructive azoospermia (NOA) are the two main types of azoospermia. Infertility is a widespread chronic condition that affects mostly people aged 25 to 44, accounting for around 15% of all couples ...
