The effect of pure phenol on sperm parameters and fertility rate in male mice
Background: Phenol is an estrogenic and toxic compound and people are widely exposed to it, in different ways. OBJECTIVES: The aim of this study was to determine the negative effects of phenol on the fertility of male mice, by investigating sperm parameters including viability, motility, fertility rates and daily sperm production (DSP). METHODS: A total of 106 adult NIH mice were divided int...
متن کاملSperm chromatin structure and male fertility: biological and clinical aspects.
Sperm chromatin/DNA integrity is essential for the accurate transmission of paternal genetic information, and normal sperm chromatin structure is important for sperm fertilizing ability. The routine examination of semen, which includes sperm concentration, motility and morphology, does not identify defects in sperm chromatin structure. The origin of sperm DNA damage and a variety of methods for...
متن کاملSperm Proteomics: Road to Male Fertility and Contraception
Spermatozoa are highly specialized cells that can be easily obtained and purified. Mature spermatozoa are transcriptionally and translationally inactive and incapable of protein synthesis. In addition, spermatozoa contain relatively higher amounts of membrane proteins compared to other cells; therefore, they are very suitable for proteomic studies. Recently, the application of proteomic approac...
متن کاملEffect of antioxidant on sperm freezing
A major cause of male infertility, which includes 50 causes of infertility, is oxidative stress. The aerobic respiration in the sperm cell is associated with the production of reactive oxygen species (ROS). Some reactions such as sperm capacitation and acrosome reactions require moderate levels of ROS. However, when the amount of ROS production surpasses the natural antioxidant defense of the ...
متن کاملProtein and carbohydrate intake influence sperm number and fertility in male cockroaches, but not sperm viability.
It is commonly assumed that because males produce many, tiny sperm, they are cheap to produce. Recent work, however, suggests that sperm production is not cost-free. If sperm are costly to produce, sperm number and/or viability should be influenced by diet, and this has been documented in numerous species. Yet few studies have examined the exact nutrients responsible for mediating these effects...
