Health education for middle school classes let us know: so special a few days each month and women will bleed, and it also indicated that they are not pregnant.
In fact, things are not so simple. Although men do not experience menstrual period, it's best to know how is the same thing. United States men's health magazine recently published a guide to tell men "women special period of 8 things."
1 not just bleed Here, women may want to roll your eyes, but don't actually know what menstruation involves the man how much? If you know, you can skip this point to the next point. If you don't know, here is the key: every month, the female's endometrium may drop out. In the course of a cycle, endometriosis will be reduced to prepare for raising a fertilized egg. If not fertilized eggs, her body was no longer needed the extra organization. Thus, shedding the lining in the menstrual period (2-7 days).
2 target time increase chances of becoming pregnant Review of biological knowledge: egg and sperm meet to pregnancy, this can only occur during ovulation. When a woman depending on her ovulation cycle length or period of days. If her average cycle is 28 days, then near usually ovulate on the 14th day. (Women can use the ovulation test strips to determine if you are Ovulating. ） The eggs can survive for 48 hours after ovulation, sperm can survive up to 72 hours after ejaculation. Therefore, if a woman on the 14th day of ovulation, so she was between the 11th and 16th days are likely to become pregnant.
3 period pregnancy Did you ever heard of the term--unprotected sex during menstruation in women is safe. In fact, this is a myth, because not all women's menstrual periods are regular. Some women short cycle, possible end to started menstruation ovulation. So, men she had sex with her on the last day of menstruation, your sperm may survive when she is Ovulating, resulting in pregnancy. In addition, if her cycle of instability, she may confuse the onset of menstruation time. Then unprotected sex at this time would be a good "made man". If you do not want to become a father, so whatever is in her menstrual period, must do well in protective measures.
4 pregnancy has "periods" If you are "busy" when the condom broke, it is likely you will be nervous before her periods. However, this does not mean that after liberation, because even if she is pregnant or may bleed. Menstruation and pregnancy is impossible while there. But pregnancy may appear to be menstrual blood. According to a study in China in 2012, 24% said in the first three months of pregnancy will be bleeding. This may be to blame for the fertilized egg implantation in the womb, or changes in hormones during pregnancy, but watch out is that this also may be the precursor to the placenta or abortion.
5 the pain really told her the same unbearable Italy a study pointed out that 80% young female menstrual pain. One-third of them is more pain, that he can't do anything else. When the start of the menstrual period, an elevated levels of chemicals called prostaglandins in the body, and helps the uterus shrink to exclude endometrial. But it can also cause cramps – similar to a throbbing pain or continual dull pain from the extension to the back of the abdomen and thigh, also can cause gastro-intestinal complaints resulting in diarrhea.
6 of premenstrual syndrome (PMS) really exist If she was angry with you, do not to "premenstrual syndrome" to make fun of her. Premenstrual syndrome began to appear about a week before menstruation, and really make a woman feel bad. Scientists don't yet know why lead to premenstrual syndrome, but it seems to be associated with the fluctuations in the level of estrogen and progesterone. Some women are sensitive to these fluctuations, causing their symptoms of premenstrual syndrome: fatigue, mood swings, gluttonous, breast pain, cramping, pain, and anxiety. Premenstrual syndrome and premenstrual anxiety disorder (PMDD) is different, PMDD, less common, is a severe type of premenstrual syndrome. Women suffering from PMDD has severe depression, can't concentrate or sleep habits change, really hinder their lives. If she has these symptoms should talk with her doctor.
7 of ovulation let her libido high Canada's research suggests women more fertile than other times of sexual fantasy, are more likely to be male "lit". This is because during this period, the female brain signals to stimulate the ovaries so they are prepared to release eggs. Her yellow body hormone (LH) and follicle-stimulating hormone (FSH) will reach its highest point at the moment. These hormonal changes make women more sensitive to stimulation of the male.
8 in or not in the mood or desire to burn When her menstrual period began, estrogen and progesterone levels plummeted, causing the women started to perceive emotions better. But that doesn't mean they want to roll sheets: spasms do not look attractive. She thinks you might be uncomfortable or her feel unnatural. However, some women will find sexual interest increased during this period, she's become more sensitive because of increased blood flow to the pelvic organs.
