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 ...

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 ...

Male Infertility in Humans: An Update on Non-obstructive Azoospermia (NOA) and Obstructive Azoospermia (OA)

2021
Non-obstructive azoospermia (NOA) and obstructive azoospermia (OA) are two common causes of infertility that affect a considerable number of men. However, few studies were performed to understand the molecular etiology of these disorders. Studies based on bioinformatics and genetic analyses in recent years, however, have yielded insightful information ...

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.
