Non-obstructive azoospermia (NOA) and obstructive azoospermia (OA) are two common causes of infertility that affect a considerable number of men. However, few studies were performed to understand the molecular etiology of these disorders. Studies based on bioinformatics and genetic analyses in recent years, however, have yielded insightful information ...

Sperm retrieval for obstructive azoospermia
Fertility and Sterility, 2008Advances in the treatment of male infertility now routinely allow men with obstructive azoospermia to have fertility treatment without microsurgical reconstruction. A variety of methods for retrieving sperm from men with obstructive azoospermia have been described.

Biological therapy for non-obstructive azoospermia
Expert Opinion on Biological Therapy, 2017Most male patients with non-obstructive azoospermia (NOA) have no therapeutic options outside of assisted reproductive techniques to conceive a biological child. If mature sperm cannot be obtained from the testes, these patients must rely on options of donor sperm or adoption.

Prostate Cystadenoma Presenting With Obstructive Azoospermia
Journal of Andrology, 2010We report on a case of prostate multilocular cystadenoma presenting with primary infertility and obstructive azoospermia. Our patient is a 36-year-old presenting with primary infertility in addition to mild deep pelvic pain. Semen analysis revealed azoospermia with positive fructose.

Corrective Surgery of Obstructive Azoospermia
Archives of Andrology, 1978Obstructive azoospermia was corrected surgically in 233 cases of vasovasotomy and 97 cases of post-inflammatory epididymovasostomy. Good results were obtained for groups of: younger age; shorter duration of obstruction; bilateral vas-to-vas anastomosis level; bilateral end-to-end anastomosis technique; bilateral oozes; no splint; and vasovasostomy ...

Obstructive Azoospermia and Vasoepididymostomy
1997Excurrent duct obstruction is a potentially reversible cause of male infertility. It can occur anywhere along the ductal system from the rete testes (empty epididymis syndrome) to the ejaculatory ducts. The incidence of obstructive azoospermia among infertile men is approximately 7% to 10%.

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.
