Preimplantation Genetic Testing for Aneuploidy (PGT-A) in Couples With Non-obstructive Azoospermia (NOA)
Objective: To examine the rate of embryo aneuploidy in patients with non-obstructive azoospermia (NOA) who utilize in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) and compare live birth rates with the utilization of preimplantation genetic testing for aneuploidy (PGT-A) vs non PGT-A.

Testicular Sperm Retrieval Rate After Varicocele Ligation in Men With Non Obstructive Azoospermia
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.
