side effects of ciprofloxacin (cpfx), a widely used broad spectrum antibiotic with fluoroquinolone core, have been reported in different organs. in the present study we sought to elucidate the impact of ciprofloxacin on sperm chromatin integrity and sperm dna damage using aniline blue and acridine orange technique, respectively. the fertility potential in male mice was also evaluated. nmri male...

Data obtained by the sperm chromatin structure assay (SCSA) on spermatozoa from nine bulls were correlated with fertility, measured by heterospermic performance (-0.94, P less than 0.01) and by alternate tests of sperm quality, including motility, acrosome integrity, Sephadex filtration and morphology of spermatozoa (all significant at P less than 0.05 to P less than 0.01). The SCSA uses flow c...

background:   objective: the aim of this study was to investigate the harmful effects of sodium arsenite on sperm parameters and the antioxidant effects of vit.e on sperm anomalies in sodium arsenite treated rats.   materials and methods: adult male rats were divided into 4 groups: control, sodium arsenite (8 mg/kg/day), vit.e (100 mg/kg/day) and sodium arsenite+vit.e. oral treatments were perf...

Objective: To compare the effectiveness of carbon dioxide and carbon dioxide-free incubation system in extracting motile, morphologically normal and chromatin intact sperm populations from the individual semen samples. Materials and Methods: Semen samples were obtained from normozoospermic men presenting for infertility evaluation. Individual samples were divided into two equal aliquots for spe...

The aim of this study was to examine the possible relationship between sperm DNA integrity and chromatin packaging evaluated by cytochemical assays, traditional sperm parameters and recurrent spontaneous abortion (RSA) of unknown origin. In this cohort study, 40 couples with a history of RSA and 40 couples with proven fertility were considered as case and control groups respectively. The semen ...

BACKGROUND Acrylamide (AA) is an important industrial chemical primarily. AA is also found in carbohydrate-rich foods that are prepared at high temperatures, such as French fries and potato chips. It is demonstrated that AA is a carcinogen and reproductive toxin and has ability to induce sperm damage. OBJECTIVE The aim of this study was to observe the effects of AA on sperm parameters and eva...

BACKGROUND Currently, relation between reactive oxygen species (ROS) ROS concentration and semen quality was indicated. Saffron has traditionally been not only considered as a food additive but also as a medicinal herb, which has a good antioxidant properties. OBJECTIVE The aim of this study was to evaluate the protection potency of saffron and vitamin E on sperm chromatin integrity. MATERI...

The process of sperm chromatin decondensation occurs when a spermatozoon enters an ovum. Protamine disulphide bonds are reduced to SH and the polycationic protamines combine with the polyanionic egg protein, nucleoplasmin, thus being stripped from DNA which then combines with histones. Defective chromatin decondensation will thus prevent further development of the male pronucleus. In this study...

An investigation involving seven boars, active in artificial insemination, and 1,350 multiparous sows was conducted at a private farm and aimed at examining the relationship between sperm quality traits and boar fertility in terms of farrowing rate and litter size. This experiment was done for 6 months. The semen samples were evaluated for subjective sperm motility and concentration. Ejaculates...
