How Normal Menstrual Cycle is Regulated

When a woman reaches puberty stage, she encounters different changes in her body. One of them is the monthly period or also known as menstruation. A menstrual cycle is a female reproductive cycle that causes monthly bleeding except during pregnancy. It lasts from menarche (the first menstruation) to menopause.

The normal menstrual cycle has an average age of
onset of 12 years but may range from 9-17 years. The normal interval of a menstrual cycle ranges from about 23 to 35 days with the average of 28 days. The average duration of menstrual flow is 2-7 days but 1-9 days of duration may also happen. The characteristic of a normal menstrual cycle in terms of amount of menstrual flow s difficult to estimate but the average is 30-80 mL per menstrual period. A pad that is saturated in less than an hour is considered heavy bleeding. The normal color of a menstrual flow is dark red and the odor is similar to marigolds.

Hormones help regulate normal menstrual cycle. They are follicle stimulating hormone (FSH), luteinizing hormone (LH), estrogen and progesterone to name a few. Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone. Estrogen and progesterone stimulate the uterus and breasts to prepare for possible fertilization and conception.

The menstrual cycle is composed of three phases: follicular or proliferative phase, ovulatory phase and luteal or secretory phase.
The menstrual cycle begins with menstrual bleeding (menstruation), which marks the first day of the follicular phase. Bleeding occurs after estrogen and progesterone levels decrease at the end of the cycle. This decrease causes the thickened lining of the uterus to break down and be shed. After menstruation, the FSH level increases slightly, stimulating the development of several ovarian follicles. The ovulatory phase begins with the increase in LH and FSH levels. LH stimulates ovulation.
During the luteal phase, LH and FSH levels decrease. The ruptured follicle closes after releasing the egg and forms a corpus luteum, which produces progesterone. Progesterone and estrogen cause the lining of the uterus to thicken more, to prepare for possible fertilization. If the egg is not fertilized, the corpus luteum degenerates and no longer produces progesterone, the estrogen level decreases, the top layers of the lining break down and are shed, and a new menstrual cycle begins.
