Sperm production in male starts at the onset of puberty and lasts lifetime. The effect of female age on the egg, which is the female reproductive cell, has been known for a very long time. Current information has revealed that the male’s age is also associated with fertility. As men get older, a decrease is observed not only in testosterone hormone production but also in producing quality sperms.The decrease in sperm count is also manifested itself with a decrease in male fertility. In addition, sperm motility and structure worsen with age. The main reason for this is that there are some numerical or structural abnormalities in the DNA that makes up the genetic structure of the sperm. Sperm with defective genetic structure are less likely to fertilize the egg. However, the use of sperms with DNA abnormalities for fertilization or insemination leads to the development of embryos with genetic defects. Consequently, the decrease in reproductive capacity and decrease in sperm quality in older men increase the probability of having a newborn with genetic disorder. For this reason, the male patients, who want to receive IVF treatment at an older age, are offered some supplementary treatment options to increase the opportunity of pregnancy and having a healthy baby.
