Therefore, the only way to know if you have gone through menopause is if you have not had your period for one year. (And it's not menopause if your periods stop for some other reason, like being sick.) The average age of menopause is 51, but for some women it happens as early as 40 or as late as 55. After you go through menopause, you are considered in the post-menopausal stage of your life.
The umbilical cord develops from and contains remnants of the yolk sac and allantois (and is therefore derived from the zygote). It forms by the fifth week of fetal development, replacing the yolk sac as the source of nutrients for the fetus.
Your baby's umbilical cord is made up of tissue and contains blood. Both cord blood and cord tissue are rich sources of powerful stem cells. Cord blood stem cells are currently used in transplant medicine to regenerate healthy blood and immune systems. Cord blood banking preserves these cells for potential treatment of 80 known diseases and disorders1, and perhaps more as research continues into these cellsâ ability to act like a bodyâs personal repair kit.
