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 ...

Obstructive Azoospermia and Vasoepididymostomy

1997
Excurrent 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, 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

Endocrine studies of azoospermia, II. Serum steroid levels in obstructive azoospermia

Archives of Andrology, 1979
Serum 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.

Obstructive and Nonobstructive Azoospermia

2007
Defined as the inability to conceive a pregnancy within 12 mo of unprotected regular intercourse, subfertility affects approx 15% of couples in the United States. Of these couples, 40 to 60% or less will have a particular male factor responsible for their difficulty conceiving.

Kallman syndrome and central non-obstructive azoospermia

Best Practice & Research Clinical Endocrinology & Metabolism, 2020
The understanding of male factors of infertility has grown exponentially in the past ten years. While clear guidelines for obstructive azoospermia have been developed, management of non-obstructive azoospermia has lagged. Specifically, management of Kallmann Syndrome and central non-obstructive azoospermia has been limited by a lack of understanding of

Genetic mutations contributing to non-obstructive azoospermia

Best Practice & Research Clinical Endocrinology & Metabolism, 2020
Non-obstructive azoospermia is a distinct diagnosis within male infertility in which no sperm is found in the ejaculate as a result of spermatogenesis failure. Because of the increased prevalence of genetic abnormalities in men with non-obstructive azoospermia, male infertility guidelines recommend screening for karyotype abnormalities and Y chromosome

Clinical outcome of microsurgery for obstructive azoospermia

International Journal of Urology, 1999
Background: Recent technical advances in microscopy have greatly improved the reconstruction of the seminal tract in cases of obstructive azoospermia.Methods: We evaluated the clinical outcome of 28 patients with obstructive azoospermia who underwent microsurgical reconstruction (i.e. vasovasostomy or unilateral epididymovasostomy).

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.

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 ...
