Secretory azoospermia or non-obstructive azoospermia?

open access: yesFolia Histochemica et Cytobiologica, 2010
In the non-obstructive azoospermia versus the secretory azoospermia it is first necessary to have a clear assessment and definition and then takes care of the patient before the surgical sampling taking into account the age of the woman and in fine try ...

Surgery for Obstructive Azoospermia

open access: yesFertility & Reproduction, 2023
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.

Obstructive azoospermia: reconstructive techniques and results

open access: yesClinics, 2013
Obstructive azoospermia is a common cause of male infertility and can result from infection, congenital anomalies, or iatrogenic injury. Microsurgical vasal reconstruction is a suitable treatment for many cases of obstructive azoospermia, although some ...

Development of a nomogram for sperm retrieval at microTESE for idiopathic non‐obstructive azoospermia in a multi‐center cohort study [PDF]

open access: hybridAndrology, EarlyView.
Abstract Background Non‐obstructive azoospermia (NOA) affects approximately 10% of infertile men and represents a major challenge in assisted reproductive technology (ART). A model that includes histological variants could be helpful in predicting sperm retrieval rate (SRR) after microdissection testicular sperm extraction (mTESE) in patients affected ...

A comprehensive review of genetics and genetic testing in azoospermia

open access: yesClinics, 2013
Azoospermia due to obstructive and non-obstructive mechanisms is a common manifestation of male infertility accounting for 10-15% of such cases. Known genetic factors are responsible for approximately 1/3 of cases of azoospermia. Nonetheless, at least 40%

Testicular expression of TDRD1, TDRD5, TDRD9 and TDRD12 in azoospermia. [PDF]

open access: yes, 2020
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 ...

Predictors of testicular sperm retrieval in patients with non-obstructive azoospermia: a review

open access: yesJournal of International Medical Research, 2021
Azoospermia is divided into two categories of obstructive azoospermia and non-obstructive azoospermia. Before 1995, couples with a male partner diagnosed with non-obstructive azoospermia had to choose sperm donation or adoption to have a child. Currently,
