Whats lethal phase and how is it calculated?
The luteal phase begins on the day of ovulation and lasts until the start of the next period. During this phase, a hormone known as LH or luteinizing hormone is released. If an egg has been fertilized, it then implants into the womb. If not, the egg slowly stops producing hormones. The lining of the uterus breaks down, which will prompt your next period to occur, thus restarting your menstrual cycle over again from the beginning
If most children look different then their parents then how are identical twins able to be produced?
When a single embryo in a mother's womb splits into two separate embryos early on in embryonic development, identical twins are created. Because the two twin embryos originate from the same single embryo, they will have extremely similar, if not identical, physical appearances and emotional actions when they are born. Identical twins are "identical' because they are created from the same original embryo during development inside the womb, not due to who their parents are.

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

What is thickening of the womb please?
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

What is the relationship between oestrogen concentration in the blood and the thickness of the lining of the womb?
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.
What is the purpose of thickening the lining of the womb?
During the years between your first period and before menopause, the lining of the womb (endometrium) thickens monthly in preparation for potential pregnancy and is discharged as "period" if the woman doesn't become pregnant.
