Microdissection testicular sperm extraction (micro-TESE): Predictive value of preoperative hormonal levels and pathology in non-obstructive azoospermia

Kaohsiung Journal of Medical Sciences, 2018
The aim of this study was to evaluate the predictive value of preoperative hormonal levels and pathology, as well as the outcome of microsurgical testicular sperm extraction in patients with non-obstructive azoospermia (NOA), presenting to our clinic for

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,

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 ...

Onco-testicular sperm extraction (onco-TESE) for bilateral testicular tumors: two case reports

Journal of Medical Case Reports, 2017
Background Most patients with testicular cancer are infertile; thus, the preservation of the sperm after surgery is an important factor to consider. We report two cases of bilateral testicular cancer in patients who underwent bilateral higher orchiectomy

Microdissection Testicular Sperm Extraction (micro-TESE) as a Sperm Acquisition Method for Men with Nonobstructive Azoospermia Seeking Fertility: Operative and Laboratory Aspects

International Brazilian Journal of Urology, 2013
Introduction Rare foci of sperm production may be found in up to 60% of men with nonobstructive azoospermia (NOA). Sperm production, if present, is minimal for sperm appearance in the ejaculate.
