The effect of intratesticular autologous platelet‐rich plasma injection on sperm retrieval rates and in vitro fertilization outcomes in couples with non‐obstructive azoospermia

The journal of obstetrics and gynaecology research
To assess the efficacy of intratesticular injection of autologous platelet‐rich plasma (PRP) in men with non‐obstructive azoospermia (NOA) and a history of failed microdissection‐testicular sperm extraction (mTESE) procedures.

An integrative prediction model of successful sperm retrieval for men with non-obstructive azoospermia.

Revista Internacional de Andrología
Microdissection testicular sperm extraction (micro-TESE) is an efficient method for obtaining spermatozoa from patients with non-obstructive azoospermia, but the overall success rate of this surgery is only approximately one-third.

Non-Obstructive Azoospermia and the Impact of MicroTESE.

Irish medical journal, 2016
In non-obstructive azoospermia (NOA), no spermatozoa are present in the ejaculate as a result of compromised or absent spermatogenesis. NOA is distinguished from obstructive azoospermia by patient history, clinical examination and hormone profile. As much as 10% of all male infertility has been attributed to NOA1. In contrast to obstructive azoospermia,

Eligibility for the medical therapy among men with non‐obstructive azoospermia—Findings from a multi‐centric cross‐sectional study

Andrology
Existing literature does not provide accurate epidemiological data regarding the true prevalence of men with non‐obstructive azoospermia (NOA) who would be eligible for hormonal optimization therapy, according to specific pre‐treatment criteria.

An integrated approach for improving clinical management of non‐obstructive azoospermia

Andrology
Non‐obstructive azoospermia is the most severe form of male infertility. A testicular biopsy is required for the diagnosis of non‐obstructive azoospermia, and the causal factors for non‐obstructive azoospermia remain unknown.

Improving Fertility in Non-Obstructive Azoospermia: Results from An Autologous Bone Marrow-Derived Mesenchymal Stromal/Stem Cell Phase I Clinical Trial

International Journal of Fertility and Sterility
Background: In this phase I clinical trial, our primary objective was to develop an innovative therapeutic approach utilizing autologous bone marrow-derived mesenchymal stromal/stem cells (BM-MSCs) for the treatment of nonobstructive azoospermia (NOA ...

Infertility treatment of men with non-obstructive azoospermia.

Acta Universitatis Palackianae Olomucensis Facultatis Medicae, 1998
Male infertility can be treated by several methods with varying degree of success. We present evidence that "open" testicular biopsy is favorable for men suffering from non-obstructive azoospermia (NOA). Moreover, any NOA patient may be subjected to this treatment even though his past histopathological examinations suggest that it is likely no sperm ...

[Microdissection testicular sperm extraction for non-obstructive azoospermia].

Zhonghua nan ke xue = National journal of andrology, 2013
Patients with non-obstructive azoospermia was once considered to be infertile due to impaired testicular spermatogenesis and consequent absence of sperm in the ejaculate. With the advent of intracytoplasmic sperm injection (ICSI), various testicular sperm retrieval techniques have been introduced recently, including fine needle aspiration, testicular ...
