3. Hormonal problems
The reason of female infertility is frequently conected with hormonal violations.
It can result absence of menstruations in general, or absence of ripening of ovule. Thus violations can touch both sexual hormones and other ones.
4. Early menopause
Early menopause (or dysfunction of ovaries) is the reason of ovulation absence. Ordinary age of female menopause - 50-55 years, but at some women the supplies of ovules by not clear reasons are closed before, menstruations are halted in 40-45 years. Many doctors are inclined to count such state by a norm and talk about the syndrome of exhaustion of ovaries. In a number of cases this state succeeds to be overcome through hormonal treatment by physiotherapy, even activations of sexual life. The reasons of syndrome of ovaries is not found out yet, although is a basic theory inherited, as an early menopause quite often is passed from a generation in a generation.
Genetic violations result complete absence of ripening of ovules, for example, syndrome of ̉ernera, at which girls give birth with underdeveloped ovaries, or with complete their absence (it is named agenezyey ovaries). Fortunately, it happens rare.
5. Polycystic ovaries
Cystic disease results both violations of exchange of hormones and the changes of ovaries. Outwardly it shows up as violations of cycle or even amenoreey, absence of ovulation, infertility. At cystic disease making is mionectic, although level of estrogen and testosterona is within the norm or even enhanceable. It is considered that the low level of FSH causes the permanent excalation of the follicles produced by ovaries, and that is why absence of mature ovules. Thus a great number of follicles appears measuring to 6-8 mm, which is possible to see by ultrasonic research. Staggered ovary usually is bigger in 2 times, its surface is covered by a smooth white capsule, through which an even ripening ovule can not get through.
6. Problems with cervical channel
If mucus of follicle uterus is too thick, spermatozoids can not overcome it. If mucus is poisonous for spermatozoids (on chemical composition or from immune features), they will simply perish, not even beginning a way to transformation in a man.
7. Cervical erosion
Cervical erosion and also the polypuses of cervix can be only the reasons of infertility due to the change of indexes of mucus, and therefore require the obligatory delete and treatment of infertility.
8. Damage of salpinxs, and also the changed uterine tubes patency
More frequent than all tubes are damaged as a result of the inflammation passed by a sexual way (or from sexual ways). Thus violations in tubes can be different - from the damage of cilia covering pipes from within to hydrosalpinxs formation (accumulation of liquid in the salpinx vacuum-sealed as a result of inflammation. On a sciagram hydrosalpinx of vyden is the enormous sack, filled by a contrasting liquid acting from uterus through the small segment of normal pipe.
In addition, salpinxs can be damaged at previous childbirth, abortion (especially - criminal, done in insanitary terms), diseases of internal (for example, appendicism or colitis).
Finally, there is such innate state of the sexual system, at which the development and structure of both uterus and tubes is broken.
