4 Process of Menstruation in Women Every Month
Windowofworld.com – Menstrual process in women takes place every month, with different cycles. Menstruation occurs due to the thickening of the uterine lining which is prepared for pregnancy. In addition to blood, menstrual fluid also contains mucus and lining cells in the uterus.
Menstrual cycles occur for 28 days, counting from the first day of the current menstrual period to the first day of the next menstrual period. Even so, not all women have the same menstrual cycle length. This cycle can sometimes come sooner or even later, depending on the conditions of each.
Understanding the Menstrual Phases
The menstrual process is divided into four phases, namely:
1. Menstrual phase
In this phase, the inner lining of the uterus (endometrium), which contains blood, cells of the uterine wall, and mucus, will decay and pass through the vagina. This phase starts from the first day of the menstrual cycle and can last for 4 to 6 days. In this phase, women will usually feel pain in the lower abdomen and back because the uterus to contract to help shed the endometrium.
2. Follicular phase
This phase lasts from the first day of menstruation to enter the ovulation phase. In this phase, the ovary will produce follicles that contain eggs. The growth of ovarian follicles causes the endometrium to thicken. This phase usually occurs on the 10th day of 28 days in a menstrual cycle. The duration of time spent in this phase determines how long a woman’s menstrual cycle lasts.
3. Ovulation phase
In the ovulation phase, the follicles produced by the ovaries release eggs to be fertilized. A mature egg will move to the fallopian tube and stick to the uterus. This egg cell only lasts for 24 hours. If it is not fertilized, the egg will die. But if the egg meets the sperm and is fertilized, the ovulation phase will mark a woman’s fertile period. Ovulation usually occurs about two weeks before the next menstrual cycle begins.
4. Luteal phase
After the ovulation phase, follicles that have ruptured and ejected eggs will form the corpus luteum in this phase. The corpus luteum will trigger an increase in the hormone progesterone to thicken the lining of the uterine lining. This phase is also known as the premenstrual phase. This phase is generally marked by a number of symptoms, such as enlarged breasts, pimples, the body feels weak, becomes irritable or emotional.
This menstrual process continues to spin, until it ends when a woman has entered menopause. Usually occurs when women aged 40 years and over.
Menstrual Hormones That Affect
The menstrual process is influenced by several hormones, including:
The hormone estrogen plays an important role in the physical formation and female reproductive organs, for example in breast growth, hair around the sex organs, producing eggs in the ovaries, and regulating the menstrual cycle. Estrogen will increase in the ovulation phase and decrease in the luteal phase.
One of the functions of the hormone progesterone is to stimulate the lining of the uterine lining to thicken and receive eggs that are ready to be fertilized. This hormone level is very low in the follicular phase and will experience an increase in the luteal phase. This hormone is produced after passing through the ovulation phase.
3. Gonadotrophin-releasing hormone / GnRh
This hormone is produced in the brain and functions to stimulate the body to produce follicle stimulating hormone and lutein hormone.
4. Follicle stimulating hormone / FSH
This hormone plays a role in egg production. In the menstrual cycle, levels of this hormone will increase before the ovulation phase.
5. Luteinizing hormone (LH)
This hormone functions to stimulate the ovaries to release eggs during ovulation. If the egg meets the sperm and is fertilized, this hormone will stimulate the corpus luteum to produce progesterone.
Normal menstrual process will occur naturally. If the menstrual process is not running normally or experiencing other disorders, you should consult a doctor for proper treatment.
