Causes of female infertility

Often the cause of infertility is a set of different factors in both partners, and to obtain the desired pregnancy have to go to the centers of assisted reproductive technologies. About half of the cases of infertility are associated with the problems of the female reproductive sphere.
There are two forms of infertility: primary - the situation when a woman has never been pregnant, and secondary - with a history of at least one pregnancy, regardless of its outcome.

In accordance with the causes, female infertility are several types:

- Endocrine infertility occurs due to an imbalance of sex hormones, which leads to disruption of follicular maturation, ovulation inability and lack of development of the endometrium.
- Tubal infertility occurs in the absence or obstruction of the fallopian tubes, making it impossible for the process of fertilization.
- Tuboperitoneal infertility caused by adhesions between the tubes and ovaries, which hinder the passage of the egg into the lumen of the tube.
- Infertility for uterine factor associated with defects of the uterus, preventing implantation embryos.
- Separately emit so-called cervical factor infertility in which sperm are killed in the cervical canal and can not get to the egg.
- Mixed forms of infertility is a combination of several of the above problems hindering the emergence of pregnancy.

Also, there are factors which themselves can not be the cause of infertility but significantly impede conception. These include diseases such as endometriosis and uterine fibroids.

Sometimes sterility can occur in healthy couples and its cause can not be determined. This phenomenon is called unexplained infertility, or idiopathic infertility.

Regardless of the disease, preventing the onset of pregnancy, it must be remembered that with age, the probability of conceiving a healthy baby decreases. Therefore, it is advisable to begin treatment for infertility in the early reproductive years and not to despair when failures.
