Colleagues have been married for 2 years, and her husband is very active in preparing for pregnancy, quit smoking and drinking, eat a healthy diet, go to bed early and get up early, look for ovulation cycle, regular “man-making”, but 2 years, a long time no movement! There are many cases like this. Nowadays, the number of couples suffering from infertility is increasing year by year. What is infertility Simply put, couples of childbearing age who have lived together for more than a year, have a normal sex life, and have never used any contraception, fail to conceive is called infertility. In medicine, such infertility is categorized into primary infertility and secondary infertility. Conception is a complex physiological process, must have the following five conditions: 1, the wife’s ovaries can discharge normal eggs. 2, the husband’s semen is normal, the husband’s semen is normal, the husband’s semen is normal, the husband’s semen is normal. 2. The husband’s semen is normal and contains normal sperm. 3, the egg and sperm can meet in the fallopian tube and combine to become a fertilized egg. 4. The fertilized egg can be transported into the uterus without any problem. 5. The wife’s uterine lining is adequately prepared for the fertilization of the egg. A problem with any of these five makes it impossible for the wife to conceive. Therefore, four of the causes that prevent conception belong to the wife’s side and one belongs to the husband’s side. Female infertility causes 1, cervical infertility The cervix is one of the important tissues and organs in the female reproductive system, and the cervix is involved in gynecology, obstetrics, family planning, women’s health care and reproductive health and other disease prevention and health care issues throughout a woman’s life. 2.Ovarian infertility Ovaries are located in the same position as testes, only the left side develops (the right side has degenerated), in the shape of grapes, all of them are follicles in different developmental periods, the follicles are yellow in color, and the surface of the ovaries is densely covered with blood vessels. The size of ovary is related to age and ovulation period. 3.Immune infertility Immune infertility, refers to the patient’s ovulation and reproductive tract function is normal, no pathogenic factors found, spouse semen routine examination in the normal range, is due to the reproductive system antigen of autoimmunity or homozygous immunity. 4, endocrine disorders infertility The human body has an endocrine system, secretion of various hormones and the nervous system together to regulate the body’s metabolism and physiological functions. Both men and women may have endocrine disorders. 5, systemic diseases and infertility Systemic diseases can also lead to infertility, obesity is also one of them. The most common systemic diseases leading to female infertility are endocrine disorders and metabolic diseases. 6, fallopian tube infertility fallopian tube is tubular, left and right, each side of the fallopian tube has two openings, the inner opening in the uterine cavity of the uterine horn, known as fallopian tube a uterine orifice, the outer opening in the abdominal cavity, known as fallopian tube an abdominal orifice. 7, vulvovaginal infertility vagina is the intercourse and semen receptacle, some vulva, vagina organic or functional diseases affect the semen or sperm into and stored in the vagina, or due to its environmental changes affect the function of normal sperm and lead to infertility. 8, sexually transmitted diseases infertility Sexual transmission is a mode of transmission, there can be a direct mode of transmission, can also be indirect mode of transmission, there is also a mode of transmission from parents to the fetus or newborn, which can be seen later in the narrative. 9, infertility caused by sexual intercourse Sexual intercourse refers to the mating behavior between male and female heterozygous animals of opposite sexes, and the characteristic that distinguishes it from other non-sexual behaviors is that sexual intercourse requires the participation of the reproductive organs to stimulate excitement, and the purpose of sexual intercourse is to procreate and reproduce as interpreted from the biological point of view. 10, endometriosis infertility The endometrium, also known as the mucosa of the uterus, is a layer of the inner wall of the uterus that constitutes a mammal.
