• patients
  • Add to these patients the countless numbers of adolescents, young and middle aged men, and athletes using AAS for cosmetic and athletic enhancement the potential population of at risk men numbers well over one million. (thinksteroids.com)
  • prevalence
  • The purpose of this study was to evaluate the prevalence of Chlamydia trachomatis , Neisseria gonorrhoeae , Mycoplasma genitalium and Ureaplasma urealyticum infections in infertile men that consulted our outpatient departments using a novel simultaneous amplification testing (SAT) that is RNA-detection based. (biomedcentral.com)
  • To the best of our knowledge, there is no data available published regarding the prevalence of C. trachomatis , N. gonorrhoeae , M. genitalium and U. urealyticum in infertile men using this novel SAT method. (biomedcentral.com)
  • found
  • For example, the percentage of sperm with highly damaged DNA, comet extent, DNA break number, and other comet measures has been found to be significantly higher in men aged 36-57 years than in those aged 20-35 years. (wikipedia.org)
  • For example, one study of 943,664 children less than 10 years old, found that, with confounding variables controlled, the risk of autism increased with increasing paternal age. (wikipedia.org)
  • health
  • While advanced age can be a possible factor in sperm motility and health, the sperm of men below 20 years of age has likewise been linked to an increase in birth defects such as neural tube defects, hypospadias, cystic kidney, and Down syndrome. (wikipedia.org)
  • There are several different ways to study the link between vitamin D and health outcomes. (fertstertforum.com)
  • and an ever increasing population of men at risk for significant health problems. (thinksteroids.com)
  • less
  • In other words, older sperm are less likely to result in a successful pregnancy and, moreover, the cumulative fragmentation of sperm DNA over time increases the likelihood that a small fraction of men will pass on achondroplasia and transmit multiple genetic and chromosomal defects. (wikipedia.org)
  • higher
  • Upon closer examination of diseases of the circulatory system, men with hypertensive disease, peripheral vascular and cerebrovascular disease, and nonischemic heart disease all displayed higher rates of semen abnormalities. (fertstertforum.com)
  • Men with positive M. genitalium RNA and U. urealyticum RNA had higher sperm DNA fragmentation index (DFI) while the comparisons of other semen parameters yielded nonsignificant results between the RNA positive and negative group. (biomedcentral.com)
  • genetic
  • Although it is possible for men to father children into old age, the genetic quality of sperm, as well as its volume and motility, all typically decrease with age. (wikipedia.org)
  • normal
  • In men with a normal level of sperm production (normozoospermia), the percentage of sperm DNA fragmentation is positively correlated with age, and inversely correlated with progressive sperm motility. (wikipedia.org)
