When a woman reaches sexual maturity, she can become pregnant as long as she has sex. Because at this time, mature sperm and mature eggs may combine to form a fertilized egg, and then develop into an embryo. However, some people do not know when they will ovulate, so when having sex, they are always nervous and afraid that they will get pregnant. Some people even ask if they can get pregnant if they have sex during their menstrual period. 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, while the uterus and fallopian tubes are reproductive organs. The ovaries contain hundreds of thousands of follicles, each of which contains an egg. The follicles are basically non-functional before puberty. During puberty, under the action of gonadotropin from the anterior pituitary gland, immature follicles gradually develop and synthesize estrogen. When the follicle matures and ovulates, the follicle wall collapses, the cells become larger and yellower, and are called the corpus luteum. It not only synthesizes estrogen but also produces progesterone. As the ovaries change, the endometrium is also affected and undergoes corresponding cyclical changes. Estrogen causes the endometrium to thicken, the endometrial cells to increase in number and size, and the blood vessels to become more tortuous and spiral, which is called the proliferative endometrium. After ovulation, due to the combined effects 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 endometrium. If the egg released at this time is fertilized, the fertilized egg is transported to the uterus through the fallopian tube for development, 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, the corpus luteum will atrophy and stop secreting estrogen and progesterone about 14 days after ovulation. At this time, the blood vessels in the endometrium will contract, the endometrium will necrotize and fall off, causing bleeding and forming menstruation. To sum up, women will not get pregnant if they have sex during their menstrual period. Women do not ovulate during their menstrual period, so they cannot get pregnant if they have sex during their menstrual period. However, during the menstrual period, the cervix of a woman is wide open. If bacteria or germs enter at this time, it will cause gynecological diseases. Therefore, if women have sex at this time, it is very easy to get infected. Therefore, it is forbidden to have sex during the menstrual period. |
