Progesterone is the hormone that maintains the lining of the uterus for the fertilized egg. The progesterone is produced by the corpus luteum for the first 8 weeks, before the placenta takes over its production.
progesterone
to get fertilized by sperm and turn into a baby
EstrogenA hormone produced by the female reproductive system is called estrogen. It regulates the release of the ovum from the ovary, down the Fallopian tube, and into the uterus. If the egg is fertilized, no new eggs will drop for nearly a year. If it is not fertilized, a new egg will drop in roughly 28 days.
After you ovulate, your egg waits to be fertilized for apprx 24 hours. If the egg is fertilized, it takes the fertilized egg about 5-12 days to travel to the uterus and implant itself in the lining. I have read that the average time for implantation is 8 days past ovulation.
It is necessary for an egg to be fertilized so the egg can hatch.
A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
Yes, a zygote is a fertilized egg.
The gametes, or "sex cells" - the sperm and ovum (egg) - become the fertilized egg (zygote) when they fuse.
A fertilized egg implants into the Uterus.
The sperm doesn't have to. Once the egg is fertilized it stays fertilized.
A period (more technically known as a menstrual cycle) is the result of hormonal changes occurring in your body on a regular basis as your body prepares itself for the possibility of carrying a child. Every month, your body produces a hormone called estrogen, the purpose of which is to produce an egg from your ovaries and to build a fertile lining in your uterus to support the egg if it is fertilized. After the egg is released from the ovary, it travels into the fallopian tube into the uterus, where if you have had sex, it may be fertilized and attach to the uterine lining, where it will grow into a baby. The space where the egg was becomes a luteal cyst and begins to secrete progesterone, which keeps the lining of the uterus healthy for the growing baby. If the egg is unfertilized, after a few days the progesterone hormone levels fall and the uterine lining begins to weaken and shed, what you know as your "period."
