Microdissection testicular sperm extraction causes spermatogenic alterations in the contralateral testis

Genetics and Molecular Research, 2010
Testicular sperm extraction (TESE) associated with intracytoplasmic sperm injection has allowed many men presenting non-obstructive azoospermia to achieve fatherhood. Microdissection TESE (microTESE) was proposed as a method to improve sperm retrieval rates in these patients; however, there have been failures.

Utility of micro-TESE in the most severe cases of non-obstructive azoospermia

Upsala Journal of Medical Sciences, 2020
The use of intracytoplasmic sperm injection (ICSI) has been a major breakthrough in the treatment of male infertility. Even patients with non-obstructive azoospermia (NOA) may benefit from the ICSI technique to father a child as long as spermatogenesis ...

Analysis of factors affecting repeat microdissection testicular sperm extraction outcomes in infertile men

Urology Research and Practice, 2019
Objective: There is no clear consensus on which patients and how many of microscopic testicular sperm extraction (mTESE) procedures will be successful. In this study, we aimed to evaluate the sperm retrieval rates and factors affecting these rates in men

Technologies to improve sperm retrieval in men undergoing micro-TESE for NOA

Asian Journal of Andrology
Nonobstructive azoospermia (NOA) is considered the most challenging clinical scenario for infertile men and current treatments leave many men unsuccessful at being able to achieve a pregnancy with their partner using their own sperm.

Anatomical considerations, testicular, and scrotal anatomy of nonobstructive azoospermia patients

Asian Journal of Andrology
Infertility, defined as the inability to conceive after 1 year of regular unprotected intercourse, impacts 10%–20% of couples globally. Both male and female factors contribute equally to this condition.

No difference in ICSI outcomes from cryopreserved testicular spermatozoa from patients with azoospermia or cryptozoospermia

Asian Journal of Andrology
Intracytoplasmic sperm injection (ICSI) with cryopreserved testicular spermatozoa retrieved via testicular sperm aspiration (TESA) or microdissection testicular sperm extraction (micro-TESE) is an effective treatment for azoospermia and cryptozoospermia.

Rescue of ICSI failure in non-obstructive azoospermia by switching from cryopreserved to fresh testicular sperm: a paired clinical analysis

Scientific Reports
Non-obstructive azoospermia (NOA) is a severe form of male infertility. Although cryopreserved testicular sperm are widely used for intracytoplasmic sperm injection (ICSI), a subset of patients experience poor outcomes with a specific frozen-thawed ...

Comparison of sperm retrieval rate between superficial and deep dissection during microscopic testicular sperm extraction

Urology Annals
Conclusion: The presented findings suggest that although successful SRRs of deep TESE were higher than that of its superficial counterpart, there was no significant statistical difference.
