Do you know what causes women infertile ?

1, vaginal factor 

As a result of the vagina or vaginal arterial in every other congenital factors, such as sexual difficulties or obstacles, thus affecting sperm into the female reproductive tract. In addition, because of mold, trichinosis's, and so on geological infection caused by inflammation of the vagina vagina biochemical changes in the environment, reduce sperm motility and viability, thus affecting the opportunity to become pregnant. 

2, cervical factor 

Cervical stenos is and polyps, cancer, adhesion's, and so on through the sperm can be affected; cervical erosion, the inflammatory exudate have spermicidal effect; cervical mucus in the presence of anti-sperm antibodies is not conducive to the sperm penetrate the cervical canal or completely lost their activities so that the sperm Capacity, which deserves attention is pregnant after abortion induced cervical adhesions, in particular, repeatedly flow more easily lead to serious complications such, the refusal of sperm in the mouth outside of the cervix. Cervical canal with multiple congenital anomalies or abnormal menstrual dysmenorrhea, after menarche in girls will go to the hospital for an examination. Gonorrhoeae and so on are caused by cervical infection through sex, and often lead to cervical canal stenosis or atresia. 

I relax with cervical disease is caused by habitual late abortions due to the common cause of infertility is one. Month of pregnancy when fetal sac increased by more than the weight bearing capacity of the cervical canal, neck expansion of Gu Chu fetal sac and the water break, the fetus and placenta have been discharged, often occur during pregnancy 3 months later. 3, uterine factor 

Congenital absence of the uterus, uterine and non-naive of the uterine cavity of the uterus, and so is bad or abnormal development will affect the woman's fertility. After the womb or after a serious enemy, endometrial inflammation, intrauterine adhesions are caused by infertility. 

About 75% of the intermediaries patients have a history of infertility, because it will cause the uterus after-adhesion, poor activities can also be caused by tubal adhesion, resulting in decreased ability to wiggle; ectopic intermediaries as a Antigen, the women's cause immunodeficiency hyperthyroidism, such as produce anti-indomitable antibodies; ectopic indomitable can produce more prostaglandins, which cause the uterus and fallopian tubes to the strong muscles to contract, interference with the operation of the egg and sperm and Yolane The implantation and therefore cause infertility. 

Uterine fibroid are women the most common benign tumor, uterine fibroid patients with infertility rate of 30-40%, much higher than the general population's rate of infertility. Submarginal fibroid which can affect the passage of sperm and the implantation of the plasticised, intramural fibrosis affect not only pregnancy but also often cause miscarriage or premature. Even if the pregnancy, by the late pregnancy, also because of abnormal uterine contraction caused by premature birth, birth or obstruction caused by postpartum hemorrhage. 

4, tubal factor 

Fallopian tube is too long or stenosis, occlusion of fallopian tube lumen caused by inflammation, adhesions or water will prevent sperm, eggs or fertilized eggs of the operation. Tubal disease may account for 25% of female infertility, infertility is a major cause of the inflammation caused by diseases, including tuberculosis, endometriosis, trichomonas, gonorrhea and other pathogenic infections. Obstruction of the fallopian tubes can pass through the liquid, microsurgery was re-pass surgery, can also "test-tube baby" (in vitro fertilization and embryo transfer) technology to help patients get the opportunity to pregnancy. 

5, ovarian factors 

Hypoplasia in ovarian follicle, ovulation and can not form a corpus luteum, premature ovarian failure, polycystic ovaries, ovarian tumors such as the impact of follicular development of emission factors or eggs can cause infertility. For example, mature follicles can not break down, then the egg can not be discharged, on the basis of their normal body temperature was two-phase type, blood hormone levels are completely normal, the disease is not known as the breakdown of the follicle syndrome. Luteal phase defect is the lack of secretion of progesterone performance, because more and prolactin levels are too high, then endometrial secretory phase of development so as to be affected is not conducive to implantation fertilized egg, even if the implantation can also as a result of pregnancy -Lack of secretion of abortion. 

Polycystic ovary syndrome is characterized by non-ovulation, it is not a single disease but a series of clinical symptoms and signs of collectively, for the performance of the menstrual disorder (menstruation or amenorrhea rare); infertility; increase bilateral ovarian, Capsule thickened, cystic change; hairy, fat, enhance sexual desire. As the endocrine and menstrual disorders and infertility caused by 6, endocrine factors 

Hypothalamus now mature incomplete or hypothalamus central mature cycle delay, so that the hypothalamus - pituitary - ovarian axis between imperfect regulation, then showed no ovulation period, luteum amenorrhea or dysfunctional, are infertility Possible causes. In addition, hyperthyroidism or low adrenal function, or hyperthyroidism can also lower the impact of ovarian function and ovulation hampered. 

7, congenital factors 

Severe congenital hypoplasia of the reproductive system, such patients often have primary amenorrhea. Sex chromosome abnormalities, such as Turner syndrome, true hermaphroditism. Chromosomal abnormalities caused by habitual abortion, and so on. 

8, systemic factors 

Dystrophy, metabolic diseases, chronic wasting disease, such as simple obesity. Health taking cottonseed oil, toxic chemical reagents, radiation, microwave, and other physical factors. 

9, the spirit of the nerve factor 

Vegetative nervous system dysfunction, mental illness, the environment of amenorrhea, anorexia nervosa, such as pregnancy leave. 

10, other 

Immune infertility, blood group incompatibility (such as the Rh factor or ABO hemolytic caused by habitual abortion or stillbirth).
