objective(s):althoughroutinely applied in assisted reproductive technology, human sperm cryopreservation is not a completely successful procedure. adverse effects of cryopreservation on the fertilization capacity, motility, morphology, and viability of spermatozoa have been proven; cryopreservation has also shown a role in sperm dna fragmentation and infertility. the post-thaw survival of sperm...

tau.amegroups.com © Translational Andrology and Urology. All rights reserved. I agree with Agarwal et al. (1) that sperm DNA fragmentation (SDF) should be included in the evaluation of male factor infertility, along with semen analysis. Although there exist divergent views on this topic, our group has routinely employed SDF (TUNEL assay) and other methods for identification of sperm DNA damage ...

objective: the present study aimed to simultaneously evaluate the association between expression of three potential factors [post-acrosomal sheath ww domain-binding protein (pawp), phospholipase cζ (plcζ), and truncated form of the kit receptor (tr-kit)] as candidates of oocyte activation with fertilization rate and early embryonic development. materials and methods: in this experimental study,...

background: the health effect of rapidly increasing everyday exposure of humans to radiofrequency radiation is a major global concern. mobile phone jammers prevent the mobile phones from receiving signals from base stations by interfering with authorized mobile carriers’ services. in spite of the fact that mobile jammer use is illegal, they are occasionally used in offices, shrines, conference ...

OBJECTIVE To assess the effect of smoking on sperm vitality, sperm DNA integrity, semen reactive oxygen species, and zinc levels in fertile men. METHODS One-hundred sixty men were investigated. They were divided into 2 equal groups: healthy fertile nonsmokers and healthy fertile smokers. They were subjected to history taking, clinical examination, and semen analysis. In their semen, sperm hyp...

BACKGROUND Previous studies have described an association between sperm with DNA damage and a history of recurrent miscarriage (RM), although it is not clear whether there is benefit in screening for sperm DNA fragmentation and to what extent DNA fragmentation impacts upon RM. AIMS To identify what proportion of couples experiencing RM are affected by DNA fragmentation abnormalities. MATERI...

background: leptin and its receptor are present in spermatozoa; however, the role of leptin in sperm function is still controversial. our present study aimed at demonstrating the effect of cryopreservation on sperm dna fragmentation (dnaf) and investigating the possible effects of sperm capacitation techniques and leptin in vitro incubation on frozen-thawed sperm dnaf and oxidative stress. meth...

BACKGROUND There is an association between aging ana an increased number of sperms with alterations in nuclear DNA. AIM To study the association between age and fragmentation of sperm DNA. MATERIAL AND METHODS Sixty two volunteers provided semen for analysis. These were separated in a group aged less than forty years and a second group aged more than forty years. Sperm DNA fragmentation was...
