 　　What is menstruation? Today I will give you a detailed introduction. Menstruation is a physiological cycle that occurs in some fertile women. female Between humans and chimpanzees and other hominins. Cows, mares, female camels, sows, ewes, etc. also menstruate, and some mammals experience estrous cycles. Women of childbearing age and female primates, every one month or so, Uterus The endometrium undergoes cyclic changes of spontaneous thickening, blood vessel proliferation, gland growth and secretion, and endometrial collapse and shedding accompanied by bleeding. This periodic vaginal discharge or uterine bleeding is called menstruation.

　　First, we must understand the structure and physiological functions of female reproductive organs in order to explain this problem.

　　The female internal reproductive organs consist of the ovaries, uterus, and fallopian tubes. The main function of the ovaries is to produce eggs and synthesize ovarian hormones. The uterus and fallopian tubes are reproductive organs. The ovaries contain hundreds of thousands of follicles, each of which contains one egg.

　　Follicles are essentially nonfunctional before puberty. During puberty, under the action of gonadotropins from the anterior pituitary gland, immature follicles gradually develop and simultaneously synthesize estrogen. When the follicle matures and ovulates, the follicle wall collapses and the cells become larger and yellower, called the corpus luteum, which synthesizes estrogen and also produces progesterone.

　　As the ovaries change, the endometrium is affected by them and undergoes corresponding cyclic changes. Estrogen makes the endometrium thicken, endometrial cells increase and enlarge, and the small arteries in the interstitium become more tortuous and spiral-shaped, which is called proliferative endometrium. After ovulation, due to the combined action of estrogen and progesterone, the endometrium becomes edematous, the glands produce a large amount of mucus and glycogen, and the thickness of the endometrium increases from 1 mm to 6 mm, which is called the secretory phase endometrium.

　　If the egg released at this time is fertilized, the fertilized egg will be transported to the uterus through the fallopian tube to develop, which is called pregnancy. The pregnancy tissue synthesizes a chorionic gonadotropin, which supports the continued development of the corpus luteum of the ovary. If the egg is not fertilized, about 14 days after ovulation, the corpus luteum atrophies and stops secreting estrogen and progesterone. At this time, the blood vessels in the endometrium contract and the endometrium becomes necrotic and falls off, causing bleeding and forming menstruation.

　　Therefore, the length of the menstrual cycle depends on the length of the ovarian cycle, which is generally 28-30 days, but varies from person to person, and can range from 23-45 days, or even 3 months or half a year. As long as it is regular, it is generally considered normal menstruation.

　　The bleeding time is generally 2-7 days, and the total amount of bleeding per menstrual period is 30-50ml. Some people think that more than 80ml of menstrual flow is a pathological condition.

　　What not to do during menstruation

　　1. Not washing the vulva

　　Many women think that it is easy to catch a cold during menstruation, so they are not used to cleaning their vulva and are afraid of catching cold and getting sick during the process of cleaning their vulva. Please remember that you should clean the vulva during menstruation, because menstrual blood, urine and other secretions will adhere to the surface of the vulva. If the vulva is not cleaned in time, bacteria can easily breed.

　　Therefore, during menstruation, be sure to be prepared to clean your vulva. If the weather is cold now and women are afraid of catching a cold, please turn on the heating lamp in the bathroom, then wet a towel with warm water, and then wipe the surface of the vulva with the towel skin and hair. After wiping it clean, just dry it with a dry towel and put on new underwear and pad it with a new sanitary napkin.

　　Of course, if you take a bath on the day, you don’t need to wipe the vulva separately. You only need to clean your hands when taking a bath, and then gently scrub the vulva.

　　2. Failure to change underwear in time

　　During menstruation, you need to wear a sanitary napkin on your underwear, otherwise, menstrual blood will flow out. Some people do not change their underwear during menstruation, and do not change it until menstruation is over. Because they think that if the underwear is attached to the sanitary napkin, the crotch will be stained with adhesive. If you change it frequently, it is easy for all the underwear to be stained. Wait until after your period to wear underwear like this. If they are not washed clean, it will cause damage to your private parts. healthy There is great damage.

　　This is wrong, because menstrual blood can easily stain your underwear during the menstrual period. If it is not changed in time, the menstrual blood will remain on your underwear, which can easily breed bacteria and cause infection and inflammation.

　　3. Keep the sanitary napkin on and don’t change it

　　Sanitary napkins are necessary during menstruation to absorb menstrual blood. Some women like to use very absorbent and thick sanitary napkins because after using them, they often do not change their sanitary napkins often. For the sake of health, sanitary napkins must be replaced frequently. Otherwise, if used for a long time, the sanitary napkins will absorb too much menstrual blood, causing the private parts to become very moist and dirty, increasing the risk of infection. Therefore, when women use sanitary napkins, please pay attention to changing them in time and don't be so lazy.
