Varicocele Repair in Patients With Nonobstructive Azoospermia: A Meta-Analysis
Journal of Urology, 2010Multiple small case series have reported sperm in the ejaculate and spontaneous pregnancies in patients with nonobstructive azoospermia after varicocele repair. We hypothesized that men with favorable testicular histopathology on testis biopsy such as maturation arrest or hypospermatogenesis would have a higher probability of success than those with ...

Value of Testicular Biopsy in Nonobstructive Azoospermia
2017One of the first problems that arise in the study of the azoospermic patient is to determine if he has a blockage of the spermatic ducts, obstructive azoospermia, or otherwise there is a primary failure in spermatogenesis, i.e., nonobstructive azoospermia (NOA). The testicular volume, FSH, and inhibin B may be normal in patients with NOA.

Clomiphene Administration for Cases of Nonobstructive Azoospermia: A Multicenter Study
Journal of Andrology, 2005ABSTRACT: Clomiphene citrate is a well‐established agent that has been empirically used in cases of idiopathic oligospermia. Clomiphene increases endogenous gonadotropin‐releasing hormone secretion from the hypothalamus and gonadotropin hormone secretion directly from the pituitary and, thus, increases intratesticular testosterone concentration.

The Argument for Varicocele Repair in Nonobstructive Azoospermia
2018Nonobstructive azoospermia (NOA) is a severe form of male factor infertility that typically obligates couples to intracytoplasmic sperm injection (ICSI) with testicular sperm. A significant proportion of these men, however, will also present with a palpable varicocele—a known modifiable risk factor for subfertility.

A novel missense variant in PNLDC1 associated with nonobstructive azoospermia
Journal of GeneticsThe most severe type of male infertility is nonobstructive azoospermia (NOA), where there is no sperm in the ejaculate due to failure of spermatogenesis. The predictable frequency of NOA in the general population is one in 100 men. Genetic studies have recognized dozens of NOA genes. Most NOA aetiologies remain idiopathic.
