Aetiological Factors in the Production of Obstructive Azoospermia
British Journal of Urology, 1984Summary— From a group of 749 infertile men, 102 (13.6%) were found to have obstructive azoospermia. An attempt is made to ascribe an aetiology to these obstructive lesions. In more than half of these patients, no cause for their obstructive lesion could be elicited.

Intracytoplasmic sperm injection in obstructive and non-obstructive azoospermia
Human Reproduction, 1997We compared the results of intracytoplasmic sperm injection (ICSI) in: (i) obstructive versus non-obstructive azoospermia, (ii) obstructive azoospermia using epididymal versus testicular spermatozoa and (iii) acquired versus congenital obstructive azoospermia due to congenital absence of the vas deferens (CAVD). A retrospective analysis was done of 241

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.

Non-Obstructive Azoospermia and the Impact of MicroTESE.
Irish medical journal, 2016In non-obstructive azoospermia (NOA), no spermatozoa are present in the ejaculate as a result of compromised or absent spermatogenesis. NOA is distinguished from obstructive azoospermia by patient history, clinical examination and hormone profile. As much as 10% of all male infertility has been attributed to NOA1. In contrast to obstructive azoospermia,
