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).

Seminal Carnitine Concentration in Obstructive Azoospermia
European Urology, 1994Seminal 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.

Corrective Surgery of Obstructive Azoospermia
Archives of Andrology, 1978Obstructive 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
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.

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.

Biological therapy for non-obstructive azoospermia
Expert Opinion on Biological Therapy, 2017Most 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.

Identification of a missense variant in CLDN2 in obstructive azoospermia [PDF]
Journal of Human Genetics, 2019 Obstructive azoospermia (OA), defined as an obstruction in any region of the male genital tract, accounts for 40% of all azoospermia cases. Of all OA cases, ~30% are thought to have a genetic origin, however, hitherto, the underlying genetic etiology of the majority of these cases remain unknown.

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 ...
