Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A varicocele is an abnormal dilatation and tortuosity of the veins of the spermatic cord. Although varicoceles are common in the general population and are frequently found on routine physical examinations, they represent the most common correctable cause of male factor infertility.

Male factor infertility affects up to half of all couples struggling to conceive, and 10-20% of men evaluated for infertility are found to be azoospermic.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Generally, azoospermia is classified as obstructive azoospermia (OA) or non-obstructive azoospermia (NOA). While OA is obviously caused by obstruction, NOA has many possible causes and is more difficult to manage.

Non-obstructive azoospermia (NOA) is most often a result of primary testicular dysfunction, Varicoceles are found in 20% of the general male population, in up to 40% of men with infertility, and specifically 4.3-13.3% of men with NOA.

The role of varicoceles in NOA has not been fully elucidated. The current best practice statement on the evaluation of azoospermic males from the AUA acknowledges that impaired spermatogenesis associated with varicoceles may be reversible but does not give a clear recommendation for management.

The primary advantage of varicocelectomy in cases of NOA is the possibility of getting motile sperms in the ejaculate. Other benefit of varicocele repairs in azoospermic men is that there are increased success rates of assisted reproductive techniques (ART) such as intracytoplasmic sperm injection (ICSI) or testicular sperm extraction (TESE).
