Sperm DNA fragmentation testing: proceed with care [PDF]
Translational Andrology and Urology, 2017 The authors should be commended for their thorough review of DNA fragmentation and the clinical indications for testing. The basic science review of DNA fragmentation, oxidative stress, and its association with male infertility is detailed yet concise. The authors also present clinical scenarios to better illustrate the current role of evaluating sperm

Can Altered Expression of HSPA2 in Varicocele Patients Lead to Abnormal Spermatogenesis? [PDF]
International Journal of Fertility and Sterility, 2010 Background Heat shock protein A2 (HSPA2) is correlated with sperm maturity and function. Therefore, dysfunctional expression of this gene results in abnormal spermatogenesis.

The role of oxidative stress in male infertility: Connection to sperm telomere shortening and overall DNA damage [PDF]
Arhiv za farmacijuMale infertility affects approximately 20% of men, with 30-40% of cases being linked to issues in both partners. While sperm production may be normal, DNA damage in spermatozoa can occur and become a primary cause of infertility.

REPRODUCTION AND SPERM DNA FRAGMENTATION
Bulletin of Problems Biology and Medicine, 2019 The aim of this work was to search and analyze literature data about sperm DNA fragmentation and its role in reproduction. There are reports that men of couples with infertility have more sperm with DNA damage. If the number of sperm DNA damage exceeds 25-30% the probability of in vivo fertilization and intrauterine insemination is estimated to be ...
