Asian Journal of Andrology, 2019 We sought to evaluate the ability of fine-needle aspiration (FNA) mapping to find sperm and to guide sperm retrieval after failed microdissection testicular sperm extraction (micro-TESE) in nonobstructive azoospermic men.

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

Microdissection testicular sperm extraction: effect of prior biopsy on success of sperm retrieval
, 2007 We determined the effect of prior biopsies with no sperm seen on the chance of sperm retrieval with microdissection testicular sperm extraction in men with nonobstructive azoospermia. A total of 311 men with NOA underwent microdissection testicular sperm

Sperm retrieval techniques for assisted reproduction [PDF]
International braz j urol, 2011 Different surgical methods such as PESA, MESA, TESA, TESE and micro-TESE have been developed to retrieve spermatozoa from either the epididymis or the testis according to the type of azoospermia, i.e., obstructive or non-obstructive. Laboratory techniques are used to remove contaminants, cellular debris, and red blood cells following collection of the ...

Is testicular microdissection the only way to retrieve sperm for non-obstructive azoospermic men?
Frontiers in Reproductive Health, 2022 Men presenting with non-obstructive azoospermia are the most challenging clinical scenario for an infertile couple. Intracytoplasmic Sperm Injection (ICSI) with testicular sperm retrieval gave a chance for biological fatherhood once sperm can be found ...

Updates on sperm retrieval techniques.
Translational andrology and urology, 2014 In the most extreme form of male infertility, the male partner is azoospermic. The advent of in vitro fertilization (IVF)-intracytoplasmic sperm injection (ICSI) has revolutionized our ability to treat azoospermia in both obstructive and non-obstructive cases.

PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility
Advanced Science, EarlyView.PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.
