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

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.

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 ...

Transvasovasostomy—An Alternative Operation for Obstructive Azoospermia

Journal of Urology, 1988
Five patients with obstructive azoospermia are presented. They were evaluated by a complete history, physical examination and semen analysis, including fructose studies, and serum testosterone and follicle-stimulating hormone determinations. A history or suspected history of epididymitis or prostatitis was identified in 4 patients and a history of ...

[Non-obstructive azoospermia and ICSI].

Contraception, fertilite, sexualite (1992), 1998
50 cases of non obstructive azoospermia required testicular sperm extraction and ICSI. Results are promising but ability to find spermatozoa remains questionable. Further studies are necessary to improve success of the method. Genetic research also need to be developed for better understanding the process.

[Testicular function in obstructive azoospermia].

Zeitschrift fur Urologie und Nephrologie, 1987
The normal histological findings of the testicles with simultaneous azoospermia according to the former opinion renders greatly probable an obstruction of the seminal ducts. The reversed case of an ascertained obstruction, however, must not necessarily contain also normal histological structures or normal hormone tests. In the obstruction syndrome in 6
