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.

Detection and Management of Obstructive Azoospermia
Urology Practice, 2015Obstructive azoospermia represents a treatable form of male factor infertility. With greater demand for assisted reproductive technologies the general urologist may be tasked with initiating the infertility evaluation and providing counsel for treatment options.

Corrective Surgery of Obstructive Azoospermia [PDF]
Archives of Andrology, 1978 Obstructive 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 ...

Existing literature does not provide accurate epidemiological data regarding the true prevalence of men with non‐obstructive azoospermia (NOA) who would be eligible for hormonal optimization therapy, according to specific pre‐treatment criteria.

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%.

Obstructive Azoospermia: A Microsurgical Success Story
Seminars in Reproductive Medicine, 2009Microsurgical techniques used in the treatment of male factor infertility have provided a revolutionary adjunct to the advent of intracytoplasmic sperm injection used in conjunction with in vitro fertilization. Previously infertile couples may now parent their own biological children and, in some cases, may even conceive naturally owing to technical ...

Seminal Carnitine Concentration in Obstructive Azoospermia
European Urology, 1994Seminal carnitine levels were studied in 67 patients with obstructive azoospermia. In 25 patients a bilateral vasectomy had been performed previously and for refertilization a vasovasostomy was performed. In the remaining 42 men the occlusion was located within the epididymis.

Intracytoplasmic sperm injection in obstructive and non-obstructive azoospermia [PDF]
Human Reproduction, 1997 We 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
