Transgendered women are sterile, they do not have ovaries or a womb.
The womb is where the baby/fetus is able to grow inside the female. The fetus can then collect nutrients from the mother via the umbilical cord, which connects the fetus with the endometrial lining.
No, a woman cannot menstruate without a womb. Menstruation occurs when the lining of the uterus sheds each month through the cervix and vagina. Without a womb, there is no lining to shed, so menstruation cannot occur.
I think that if the relationship between oestrogen and the blood lining is that if it is low, there is a stop in the progression of blood lining and lining begins to break down, as oestrogen causes progesterone hormone that creates the thick mucus lining around the uterus and maintain it. When there is high concentration of oestrogen in the blood, it can help in maintaining the lining and creating the mucus in the uterus. Sometimes if there is a real high concentration in the blood, like when you take a contraceptive, it can cause blood clots to happen.
Menstruation is caused by the break-down of the lining of the womb. This happens when no egg implants. Once an eggs is fertilised it attaches to the womb's lining, so the lining does not break down.
Oestrogen & Progesterone are produced by the Ovaries. Follicle Stimulating Hormone (FSH) & Lutenizing Hormone (LH) are produced by the pituitary gland at the base of the brain. FSH and LH control and stimulate the unripe eggs inthe ovaries to ripen and be released. Oestrogen & progesterone stimulate the formation of the endometrium lining in the womb, and by reducing in levels ultimatly casue the breakdown of the lining, and the ensuing period know as menstruation in human females
The uterus. A major female hormone-responsive reproductive sex organ of most mammals. Where the young grow inside the female before birth.
Because it has blood clots and womb lining in it
The membrane lining the inner surface of the uterus, or womb.
A Wombat? No, the only things that a human can grow in their womb is either a baby or a tumour.
Thickening of the womb happens every month during a woman's monthly cycle. It is when the lining of the womb builds up so that if the egg is fertilised it will have a soft, spongy lining to implant into and will be protected throughout the pregnancy If the egg is not fertilised, the lining breaks down as it is not needed, and that is what a period is The thickening of the womb is caused by hormones that trigger it to thicken
