Sperm DNA Fragmentation

Gharagozloo P, Aitken RJ The role of sperm oxidative stress in male infertility and the significance of oral antioxidant therapy. This test is an effective method for measuring DNA damage in thousands of sperm in an ejaculate. Initial reports suggest that DNA damage occurs at the post-testicular level, so that testicular sperm may have a healthier DNA integrity than ejaculated sperm 33, Gavriliouk D, Aitken R. Varicocoele is the leading known cause of male infertility and it is associated with sperm DNA damage Other factors include defects in sperm chromatin packaging and DNA repair mechanisms as well as abnormalities in the regulation of programmed cell death abortive apoptosis which is vital for regulating sperm production

Syst Biol Reprod Med 57 However, this test does not provide any information about the genetic constitution of the sperm, which is essential for normal embryo development. Normal f ull-term pregnancies are possible with an elevated DFI, but the higher the level of fragmentation, the greater the incidence of reduced term pregnancies and miscarriage. Adv Exp Med Biol One systematic review article suggests that current sperm DNA fragmentation tests have limited capacity to predict the chance of pregnancy following assisted conception treatment 14 , however several large studies, systematic reviews and meta-analyses have revealed that high sperm DNA fragmentation is associated with reduced natural pregnancy rates 6 and assisted conception pregnancy rates 5,6,10,13 as well as live birth rates

I'm not her husband but I do love bathing that cunt with my gooy seed. She complained to me about how her husband won't come near her. I don't get it, I can't fuck her enough, she's so pretty.
