The price and value of sperm DNA fragmentation tests [PDF]

open access: yesTranslational Andrology and Urology, 2017
Drs. Fraczek and Kurpisz, in their insightful commentary, highlighted the pitfalls of the current sperm DNA fragmentation (SDF) testing (1). These authors remarked that the association between SDF and clinical outcome of assisted reproduction is not without controversy in the literature.

The effect of rhFSH on Sperm DNA Fragmentation and sperm parameters in Oligozoospermia Infertile Men

open access: yesResearch in Molecular Medicine, 2020
Background: One of the main causes of male infertility is the negative effects of oxidative stress. Follicle-stimulating hormone (FSH) plays an essential role in spermatogenesis, as well as in the maintenance of sperm DNA integrity.

Sperm DNA fragmentation and male subfertility

open access: yes, 2012
The aims of the present study were to investigate whether: 1. There is a difference in sperm DNA fragmentation between subfertile men and fertile controls. 2. Sperm DNA fragmentation differs among men with different causes of subfertility. 3.

Fragmentation dynamics of frozen-thawed ram sperm DNA is modulated by sperm concentration

open access: yes, 2010
This study investigated the hypothesis that post-thaw incubation of ram sperm at high concentrations results in a faster rate of DNA fragmentation than when sperm are incubated at a lower concentration.

Risk factors associated with sperm DNA fragmentation [PDF]

open access: yesTranslational Andrology and Urology, 2017
Dr. Franco (1) in his commentary in response to the practice recommendations by Agarwal et al . (2) provides information on several important aspects of sperm DNA fragmentation (SDF), especially the impact of paternal age, overweight and varicocele; and finally the author concluded by listing the current limitations of SDF tests.

Amphibian sperm DNA fragmentation [PDF]

open access: yes, 2016
There are extremely limited studies that have investigated DNA fragmentation in amphibians and even less information exists pertaining to DNA fragmentation in the spermatozoa. A DNA fragmentation assay applied and validated for amphibian spermatozoa would not only provide the first evidence of this phenomenon in a new major taxon, but also prove a ...

Sperm DNA fragmentation testing is the way forward [PDF]

open access: yesTranslational Andrology and Urology, 2017
It is my pleasure to write the foreword to this focused edition on sperm DNA fragmentation. This topic is one of the most exciting in male fertility diagnosis and treatment today and it has still so much untapped potential. After years of struggling with outdated diagnostic tools we have discovered DNA fragmentation; a sensitive and speci c property of
