The very moment of fertilization, the egg has chemical changes which prevent other sperm from entering. Then over the next several days the first formations begin, cell by cell. At 6-8 weeks after last period, the baby has primitive organs and all of the basic foundational structures that will become facial features, toes, feet, head, arms, etc.
Uterus. The fertilized egg continues to grow developing into a fetus.
Yes, but you should make sure that the fetus has not begun to grow in the egg.
The most immediate external effect of an egg being fertilized, is that a change occurs in the egg such that it either repels all other sperm, or at least is no longer accessible to them.
A female's fertilized egg spends the majority of time in the uterus. This is where the egg will mature and grow.
The fertilized egg (which develops into a baby eventually) implants itself into the uterine wall/lining. The lining surrounds the egg as it matures and develops into a fetus and a placenta and amniotic sac surrounds the fetus eventually to nourish it.
Uterus. The fertilized egg continues to grow developing into a fetus.
No. All fetus' start as an egg that is fertilized from the male and the cells divide. Gender is determined at conception from the DNA in the sperm but it cannot be detected until a later time. Check www.3dpregnacny.com for week by week development of a fetus.
The uterus grow to make room for the fetus. A fetus that doesn't grow - no growth of the uterus.
No, a sac grows to accommodate the fetus and if the fetus us dead it does not grow anymore.
when the ovary is fertilized the the fertilized egg will become a zygote
There is really no way to know until the fetus is starting to grow... Before the sperm is ejaculated into the female you wont know... Because if the fetus is just starting to grow the male testosterone will start pumping from the fetuses brain and cause his penis to start growing...
The embryo (fetus is a term usually reserved for placental animals) will start to grow on the germinal disc on the yolk when the egg is incubated. Celluar division can start as soon as the egg temperature goes above 85 degrees F, but isn't optimal until it is 99-100 degrees F.
