Where does human beings life originate? Your human body comes into existence as a result of the act of procreation through the union of the male sperm and female egg. That is scientific proven fact. The soul, life containing organ is separately introduced into the body six to seven weeks after conception. This proposition is backed by scientific proof. The heart in a fetus does not begin to beat the moment male sperm fertilizers the female egg.
A woman is endowed with enough eggs she will ever need in her life for procreation. Men are also capable of producing sperm throughout their life. Age slows a man’s sexual activity but does not affect production of the eggs. How long can a sperm cell live once inside a woman’s body? About two days.
You would think the sperm capability to move slackens in case of making test tube babies. A man’s DNA in the sperm has the power for that movement even in the absence of the natural fluid.
When the male sperm gets in touch with the right egg for fertilization, exchange of the man and woman’s DNA take place. The man’s Y chromosome is passed on from father to son because it has no female egg counterpart.
