Corrective Surgery of Obstructive Azoospermia

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 ...

Seminal Carnitine Concentration in Obstructive Azoospermia

European Urology, 1994
Seminal 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.

Testicular Biopsy in Patients With Obstructive Azoospermia

The American Journal of Surgical Pathology, 1999
The present report studies the testicular biopsy lesions (histologic and semiquantitative) in a series of 48 patients with obstructive azoospermia of known etiology (vasectomy, congenital absence of vas deferens, herniorrhaphy, hydrocelectomy, Young's syndrome, and ejaculatory duct obstruction) in order to establish objective testicular data that ...

OUTCOME OF SURGICAL TREATMENT FOR OBSTRUCTIVE AZOOSPERMIA

Archives of Andrology, 2002
The efficacy of reanastomosis was evaluated in 30 patients with obstructive azoospermia, including 19 postvasectomy cases; 7 cases complicating inguinal herniorrhaphy; 2 cases with a characterized isolated congenital anomaly; 1 case of Young's syndrome; and 1 case with an unknown, possibly congenital cause. In the postvasectomy group.

Biological therapy for non-obstructive azoospermia

Expert Opinion on Biological Therapy, 2017
Most 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.

Identification of a missense variant in CLDN2 in obstructive azoospermia [PDF]

Journal of Human Genetics, 2019
Obstructive azoospermia (OA), defined as an obstruction in any region of the male genital tract, accounts for 40% of all azoospermia cases. Of all OA cases, ~30% are thought to have a genetic origin, however, hitherto, the underlying genetic etiology of the majority of these cases remain unknown.

Intracytoplasmic sperm injection in obstructive and non-obstructive azoospermia

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

Aetiological Factors in the Production of Obstructive Azoospermia

British Journal of Urology, 1984
Summary— 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.
