A human ovum in and of itself is no more than a female germ cell or
egg. It is not a "person" and should not be granted "legal personhood".
Since we are including the word "human" here, that would seem to grab
the conscious of some people and make them think that we were talking
about a human life, not a "human ovum".
Human reproduction cannot
take place using only a female ovum any more successfully than it can by
using only male sperm. It takes both.
In order to determine an
approximate due date in a pregnancy, the doctor normally counts forward
40 weeks from the woman's last menstrual period. This means that the
woman's last period is actually counted as part of her pregnancy when
she actually wasn't pregnant.
Since I am not a doctor or
biologist, I had to get some expert advice on this topic and I chose the
Mayo Clinic and according to them, pregnancy begins with a fertilized
egg (ovum). When the egg or ovum and sperm unite, they form a one-celled
entity called a "zygote", so you see, it isn't called an "ovum"
anymore. The chromosomes in the zygote contain genetic material that
will determine the baby's sex, eye and hair color, height, etc.
