Testicular and epididymal spermatozoa are used routinely for intracytoplasmic sperm injection (ICSI) to treat men with obstructive azoospermia. Little is known of the effects of obstruction and stasis on the DNA of these spermatozoa, particularly in the epididymis where spermatozoa have been retained for long periods. Surgical epididymal aspiration for ICSI could provide spermatozoa that are senescent or dying. Using the Comet assay, the percentage of undamaged DNA of testicular spermatozoa…

A comparison of mitochondrial and nuclear DNA status in testicular sperm from fertile men and those with obstructive azoospermia.
TLDR
Multiple mt DNA deletions are common in testicular and ejaculated sperm from both fertile and infertile men, however, in males with obstructive azoospermia, the mtDNA deletions intesticular sperm are of a larger scale.
Morphological and morphometric attributes of epididymal and testicular spermatozoa following surgical sperm retrieval for obstructive and nonobstructive azoospermia
Summary. Whilst the morphological (shape) and morphometric (sperm head size) attributes of ejaculated spermatozoa have been well studied, the morphological and morphometric qualities of testicular

Effect on clinical outcome of the interval between collection of epididymal and testicular spermatozoa and intracytoplasmic sperm injection in obstructive azoospermia.
TLDR
It is confirmed that fertilization and pregnancy rates following ICSI with motile spermatozoa are unaffected by the duration between surgical retrieval of spermatozosa and their injection into oocytes, and it is demonstrated that of all treatment modalities, the use of frozen epididymal spermarozoa was associated with the greatest pregnancy rates.
Use of Testicular Sperm for ICSI: Pro
TLDR
Current data indicate that the use of testicular sperm is associated with improved ICSI outcomes in men with oligozoospermia and high SDF, and a call for continuous monitoring is nonetheless required until the safety of this strategy to the health of offspring is confirmed.
ICSI outcomes in obstructive azoospermia: influence of the origin of surgically retrieved spermatozoa and the cause of obstruction.
TLDR
It is suggested that the use of testicular spermatozoa, even those generated during normal spermatogenesis, alters embryonic development and that epididymal spermutozoa should be preferentially used, irrespective of the aetiology of OA.
Mitochondrial DNA deletions and nuclear DNA fragmentation in testicular and epididymal human sperm.
TLDR
This study suggests that mtDNA and nDNA of testicular sperm have fewer mutations and fragmentation than epididymal sperm and should be used in preference for ICSI in clinical treatment.

High fertilization and pregnancy rate after intracytoplasmic sperm injection with spermatozoa obtained from testicle biopsy.
TLDR
It appears that all cases of obstructive azoospermia can now be successfully treated and the few barely motile spermatozoa thus obtained can be used for ICSI.
Fertilizing capacity of epididymal and testicular sperm using intracytoplasmic sperm injection (ICSI).
TLDR
It is concluded that although complex mechanisms involving epididymal transport may be beneficial for conventional fertilization of human oocytes (in vivo or in vitro), none of these mechanisms are required for fertilization after ICSI.
The result of intracytoplasmic sperm injection is not related to any of the three basic sperm parameters.
TLDR
The results showed that there was no important influence from either the type or the extent of sperm impairment on the outcome of ICSI, and the only ultimate criterion for successful ICSi is the presence of at least one living spermatozoon per oocyte in the pellet of the treated semen sample used for micro-injection.
Fertilization, pregnancy and embryo implantation rates after ICSI with fresh or frozen-thawed testicular spermatozoa.
TLDR
It is shown that it is possible to achieve a high fertilization rate after ICSI with both fresh and frozen-thawed testicular spermatozoa but implantation and live birth rates per transferred embryo, however, are significantly lower after I CSI with frozen- thawed than with fresh testicular semen.

The fertility potential of male cystic fibrosis patients.
TLDR
In testicular biopsies from two patients with CF normal spermatogenesis was found despite the absence of sperm in the ejaculate, indicating normal prostatic function and absence of seminal vesicles.
