There are several reasons why the eggs do not break: first, the eggs should refer to the follicles, because the follicles harbor the eggs, if the follicles do not break, the most common original is that the follicles are not developed, that is, the female expelled follicles too early. The follicles that are discharged too early do not receive sufficient nutrition in the woman’s ovaries or are not yet well developed, so the discharged follicles will not rupture spontaneously even after a long time and cannot release the eggs in them. Secondly, women may suffer from ovarian inflammation. Follicles have a long time to grow and develop in the ovaries, and if the ovaries suffer from inflammation it can seriously affect the development of the follicles. If the follicle development is obstructed or deviates from the normal direction, such a follicle will not break easily. Third, it may be a congenital problem of the follicle, because congenital disorders are caused by genetic abnormalities. If the genes that control the normal development of the follicle are mutated or recombined, it will lead to abnormal follicle development, and such follicles will not be able to rupture. Fourth, it may be caused by the woman’s age and poor follicular vitality. This is because as women age, the vitality, or motility, of the follicles they expel is relatively poor, and such follicles are difficult to break.
