Scars on the shell of ovaries can result the loss of ability to produce follicles. Scars appear as a result of vast or repeated surgical interferences (for example, on an occasion of an oothecoma). The infectious diseases also can result formation of plenty of scars on an ovary that hinders to normal development of follicles and conduces to absence of ovulation.
9. Problems with follicle
At some women normal follicles with an ovule ripen every month. But on an incomprehensible reason a follicle somethimes does not tear in time, an ovule remains into an ovary and can not participate in the impregnation. The reasons of such state are unknown; there is even more or less no acceptable hypothesis about the reasons of what is going on.
10. Endometriosis
In the norm of mew of endometriosis form the internal surface of uterus, helps an embryo to feed, and in absence of pregnancy participate in menstruation. At endometriosis of mew endometry overgrows, forming as though polypuses or deep "pockets" in the layer of uterus can get to the salpinxs, ovaries and even in an abdominal region. Endometriosis violates the processes of ripening of ovule, interferes with confluence of ovule and spermatozoon, and also violates attachment of the impregnated ovule to the wall of uterus.
Psychological reasons could be the cause for infertility. But, at the same time, such states are known, as amenorey of war-time, stressing amenorey, even examination amenorey, when from stress the natural functions of female organism are violated.
11. In addition, exactly to psychological attribute the reasons of infertility of not clearing genesis
A woman (rarer at man) subconsciously has negative attitude toward possible pregnancy, and that is why, her organism automatically does not allow to be accomplished to the processes resulting in conception.
12. Violations of uterus structure
Any formations deforming the cavity of uterus operate as endometrial spiral, not allowing the ovule to register to endometry. The polypuses of mucous uterus, hysteromyoma, endometrioid formation and also innate states - bicornate uterus, uterus with incomplete partition, double uterus and other diseases contribute to the infertility, these features of structure are not inherited, and are easily exposed on ultrasonic, but treatment represents considerable difficulties.
Finally, absolute female infertility is absence or proof obstruction of salpinxs, is a testimony to extracorporal impregnation with the subsequent transfer of embryos in the uterus of mother.
