Differentiation between nonobstructive azoospermia and obstructive azoospermia: then and now. [PDF]
Abstract Male infertility has seen an increase in prevalence with cases of azoospermia estimated to affect 10%–15% of infertile men. Confirmation of azoospermia subsequently necessitates an early causal differentiation between obstructive azoospermia (OA) and nonobstructive azoospermia (NOA).

Testicular expression of TDRD1, TDRD5, TDRD9 and TDRD12 in azoospermia. [PDF]
BACKGROUND: Tudor domain-containing proteins (TDRDs) play a critical role in piRNA biogenesis and germ cell development. piRNAs, small regulatory RNAs, act by silencing of transposons during germline development and it has recently been shown in animal ...

Management of non‐obstructive azoospermia [PDF]
AbstractNon‐obstructive azoospermia (NOA) is defined as no sperm in the ejaculate due to failure of spermatogenesis and is the most severe form of male infertility. The etiology of NOA is either intrinsic testicular impairment or inadequate gonadotropin production.

Surgery for Obstructive Azoospermia
Microsurgical technique in male infertility has progressed significantly since the introduction of intracytoplasmic sperm infection (ICSI) 30 years ago. The searching of sperm available for ICSI becomes the main tasks for reproductive andrologists. At the initial study for patients with azoospermia, it is crucial to differentiate obstructive causes ...

A novel stepwise micro-TESE approach in non obstructive azoospermia [PDF]
Background: The purpose of the study was to investigate whether micro-TESE can improve sperm retrieval rate (SRR) compared to conventional single TESE biopsy on the same testicle or to contralateral multiple TESE, by employing a novel stepwise micro ...

Loss of Cx43 in Murine Sertoli Cells Leads to Altered Prepubertal Sertoli Cell Maturation and Impairment of the Mitosis-Meiosis Switch. [PDF]
Male factor infertility is a problem in today's society but many underlying causes are still unknown. The generation of a conditional Sertoli cell (SC)-specific connexin 43 (Cx43) knockout mouse line (SCCx43KO) has provided a translational model ...

Testicular histopathology, semen analysis and FSH, predictive value of sperm retrieval: supportive counseling in case of reoperation after testicular sperm extraction (TESE) [PDF]
Background: To provide indicators for the likelihood of sperm retrieval in patients undergoing testicular sperm extraction is a major issue in the management of male infertility by TESE.
