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 ...

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 ...

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.

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

Endocrine studies of azoospermia, II. Serum steroid levels in obstructive azoospermia
Archives of Andrology, 1979Serum estrone, estradiol, estriol, progesterone, 17 alpha-hydroxyprogesterone, and testosterone were determined in the sera of 25 normal males and 25 patients with obstructive azoospermia. An increase in testosterone and estriol levels, and a decrease in other hormones were demonstrated in patients with obstructive azoospermia.

Diagnostic and clinical features in azoospermia
Clinical Endocrinology, 1995SummaryBACKGROUND AND OBJECTIVE The recent advances In assisted fertilization and gamete micromanipulation techniques have enabled fertilization in some forms of azoospermia; for example, epididymal sperm aspiration in obstructive azoospermia. Therefore knowledge of the specific degree of testicular damage is of primary importance, since other clinical

Varicocele is found in 5 % of men with NOA, but its absolute impact on the azoospermic status is still unknown. The advent of assisted reproductive technologies (ART), particularly intracytoplasmic sperm injection (ICSI), has reintroduced the awareness about varicocele with NOA, as improvement in testicular function to obtain viable sperm for ART may ...

Controversies in the management of nonobstructive azoospermia
Fertility and Sterility, 2009The fertility potential of patients with nonobstructive azoospermia (NOA) depends on sperm extraction from the tissue sample and then in vitro fertilization with intracytoplasmic sperm injection (IVF/ICSI). Unfortunately, there is no consensus regarding predictors that can identify nonobstructive azoospermic men with a potentially high yield at the ...

Varicoceles are present in approximately 15% of men in the general population and 40% of men presenting for fertility evaluations. One percent of men in the general population are azoospermic and 15% of men presenting for fertility evaluations are found to be azoospermic.
