introduction: tegrity is the most important component for transferring genetic information sperm dna fragmentation is considered a component of male infertility. its assessment comprises conventional semen analysis of which emphasis is placed on its evaluation in fertility clinics. in this study, we investigate the relationship between sperm parameters of motility, morphology, concentration, an...

this study analyzed the determinants of the productivity of smallholder arable crop farmers with a particular focus on land fragmentation using the simpson index as measures of land fragmentation in imo state of nigeria. data collected by using structured questionnaire and interview schedules were analyzed using simple descriptive statistics; simpson index and regression analysis. results showe...

Background Sperm DNA fragmentation is known as an important cause of male infertility. The influence of sperm DNA damage on reproductive potential has been subject of many studies indicating various results and remaining the subject controversial. In this study, we investigated differences of the semen parameters and intracytoplasmic sperm injection (ICSI) outcome according to sperm DNA fragmen...

We calculate the exact fragmentation functions for c and b quark fragmentation taking into account the spin orientation of the initial heavy quark in the form of analytical and rather simple expressions. Our calculations show that spin orientation may have an important effect on the fragmentation spectrum. This effect is more striking in the cases of c ?D, D*; c? ? , ? , and ?B , B *.

background: although the effectiveness of ginger as an antioxidant agent has been exploited, little human research has been conducted on its activity on male reproductive functions. objective: this study was designed to investigate the effects of ginger (zingiber officinale) on sperm dna fragmentation (sdf) in infertile men. materials and methods: this randomized double-blind, placebo-controlle...

Background: Infertility is estimated to affect up to 15% of couples of reproductive age, and male factors contribute to 50% of these cases. Globozoospermia syndrome is a severe form of teratozoospermia, with an incidence of less than 0.1%. It is characterized by round sperm head. The most prominent feature of globozoospermia is the malformation of the acrosome, which is totally absent in the to...
