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.

A step closer to parenthood with non‐obstructive azoospermia: Unveiling the impact of microdissection testicular sperm extraction in Australia's largest single‐centre study

Australian and New Zealand journal of obstetrics and gynaecology
Non‐obstructive azoospermia (NOA) diagnosis poses challenges for couples seeking parenthood. Microdissection testicular sperm extraction (MD‐TESE) excels in retrieving testicular sperm cells for NOA cases.

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.

Glucose and lipid profiles in men with non-obstructive azoospermia

2022
AbstractThe impact of a low testosterone level among men with non-obstructive azoospermia with various testicular histopathological patterns on the regulation of glucose and lipid metabolism is less well known than among the general population. The aim of this retrospective study was to examine the association between testicular histopathology and ...

Analysis of genes implicated in non-obstructive azoospermia

Steroids
Non-obstructive azoospermia (NOA) is the most common cause of male infertility, accounting for approximately 60 % of azoospermia cases. In recent years, gene mutations have emerged as the primary factor under investigation for the etiology of NOA. Therefore, finding the cause and pathogenesis of NOA at the genetic level has become one of the current ...

Non-obstructive azoospermia and clinical varicocele: therapeutic options

International Urology and Nephrology, 2013
Ten to fifteen percent of infertile men are azoospermic, and sixty percent of these men have been classified as having non-obstructive azoospermia (NOA). NOA results from testicular failure, and one of the causes of this is the presence of varicocele. Varicocele is observed in 5-10 % of men with NOA.

Male Infertility in Humans: An Update on Non-obstructive Azoospermia (NOA) and Obstructive Azoospermia (OA)

2021
Non-obstructive azoospermia (NOA) and obstructive azoospermia (OA) are two common causes of infertility that affect a considerable number of men. However, few studies were performed to understand the molecular etiology of these disorders. Studies based on bioinformatics and genetic analyses in recent years, however, have yielded insightful information ...

GENETIC ANOMALIES DETECTED IN PATIENTS WITH NON-OBSTRUCTIVE AZOOSPERMIA AND OLIGOZOOSPERMIA

Archives of Andrology, 2006
Genetic factors have a major importance in male infertility etiology. Numerical and structural chromosomal abnormalities seem to be frequent inoligospermia and azoospermia cases with unknown etiology. In this study, 819 patients with azoospermia (383) and oligospermia (436) who attended the infertility department between 1995-2005 were evaluated ...

Recent concepts in the management of infertility because of non-obstructive azoospermia

Human Reproduction, 1995
Testicular biopsy has been widely used for the diagnosis of male infertility. Since the introduction of intracytoplasmic sperm injection (ICSI), spermatozoa recovered from a testicular biopsy specimen can be successfully used for establishing pregnancies.
