When does the hormones level drop and the uterus lining starts to break down?
Hormone levels drop and the uterus lining starts to break down during a woman's menstrual cycle. This typically occurs after ovulation when there is no pregnancy, leading to the shedding of the uterine lining in the form of a menstrual period.
How does the shedding of the uterine lining contribute to the presence of blood in period blood?
During menstruation, the shedding of the uterine lining causes blood vessels to break, leading to the presence of blood in period blood.
How does the process of implantation of an embryo occur in the human body?
During implantation, the embryo attaches to the uterine lining and begins to grow. This process involves the embryo releasing enzymes to break down the uterine lining, allowing it to burrow in and establish a connection for nutrient exchange with the mother's blood vessels.
What and the lining of the uterus break down?
The uterine lining builds-up following ovulation in preparation for possible pregnancy, to allow the zygote to implant and nourish the growing 'baby'. If pregnancy doesn't occur the drop in progesterone triggers the uterus lining to break down, this is called menstruation.
Does the lining of your uterus always come out during your period?
Yes, it does, unless it did not build up in the first place. As soon as your period ends, the womb lining begins to build up and thicken so that if the egg is fertilised, there will be a thick, safe, spongy environment for it to implant in. If the egg has not been fertilised, it will break down during your period because it is not needed. However, sometimes, the right hormones are not being produced or not enough of them are produced and the womb lining does not build up, therefore it does not break down either
When does the uterine lining begin to break down?
During Menstruation. The uterine lining sheds to prepare the uterus for pregnancy. It's due to the drop in estrogen and progesterone.

Is thickening the endometrium the main function of progesterone during menstrual cycle?
Yes, thickening of the uterine lining is one of the main functions of progesterone during the menstrual cycle, allowing the womb to build-up the uterine lining to support a fertilised egg. If pregnancy doesn't occur then it's the drop in progesterone that causes the uterine lining to break down.
Why do women stop having periods during pregnancy?
Your period is the breakdown of the uterine lining. Once a pregnancy is established by the embryo implanting in the uterine lining, the hormone hCG and progesterone kick in to prevent the breakdown. While pregnant the lining does not break down because it is being used to support the placenta and fetus.

Why does mensuration not take place after fertilisation?
The uterine lining builds-up in preparation for fertilization so that the zygote/embryo can implant itself into the uterine lining and then develop into a baby. Menstruation only takes place when fertilization doesn't take place, this occurs so the uterine lining is shed and can start a fresh next cycle so it can be ready for pregnancy again. If the uterine lining were to break down after fertilization a zygote/embryo wouldn't be able to implant itself or it would result in miscarriage.

Why can't you have a period when your pregnant?
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.
If the egg is not fertilized when does it begin to break down?
If the egg is not fertilized, it will start to break down within 24 hours of ovulation. The breakdown process includes disintegration of the egg and shedding of the uterine lining during menstruation.
