Imaging of obstructive azoospermia
European Radiology, 1997Obstructive 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.

Detection and Management of Obstructive Azoospermia
Urology Practice, 2015Obstructive azoospermia represents a treatable form of male factor infertility. With greater demand for assisted reproductive technologies the general urologist may be tasked with initiating the infertility evaluation and providing counsel for treatment options.

Obstructive and Non-Obstructive Azoospermia
2012Azoospermia is defined as the complete absence of spermatozoa upon examination of the semen [including capillary tube centrifugation (CTC), strictly confirmed by the absence of spermatozoa issued in urine after ejaculation]. The presence of rare spermatozoa (

Sperm retrieval for obstructive azoospermia
Fertility and Sterility, 2008Advances in the treatment of male infertility now routinely allow men with obstructive azoospermia to have fertility treatment without microsurgical reconstruction. A variety of methods for retrieving sperm from men with obstructive azoospermia have been described.

Clinical outcome of microsurgery for obstructive azoospermia
International Journal of Urology, 1999Background: 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).

Sperm antibodies in a patient with obstructive azoospermia
Journal of Reproductive Immunology, 1993An artificial spermatocoele was constructed at the level of the caput epididymis in a patient with obstructive azoospermia. Morphologically normal spermatozoa were harvested but motility and progression were inadequate for intra-uterine insemination or in vitro fertilisation.

Obstructive Azoospermia and Vasoepididymostomy
1997Excurrent 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%.

Obstructive and Nonobstructive Azoospermia
2007Defined 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.

Obstructive Azoospermia: A Microsurgical Success Story
Seminars in Reproductive Medicine, 2009Microsurgical 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 ...
