Obstructive Azoospermia

Urologic Clinics of North America, 2014
Obstructive azoospermia accounts for 40% of azoospermia and results from obstruction of the excurrent ducts (due to many causes) at any location between the rete testis and the ejaculatory ducts. The diagnosis of obstructive azoospermia (OA) requires a stepwise approach to differentiate it from nonobstructive OA and to formulate management options ...

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

Imaging of obstructive azoospermia

European Radiology, 1997
Obstructive 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.

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.

Obstructive Azoospermia: A Microsurgical Success Story

Seminars in Reproductive Medicine, 2009
Microsurgical 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 ...
