The most common cause of a women's low egg count is age. This cause is physiological, unavoidable and increasing, since for socio-cultural reasons women are having children at a later age.
There are many others, either because the patient did not generate enough oocytes in her embryonic stage (genetic causes) or because of damage to the ovary (infection, ovarian torsion, endometriosis, surgery, radio or chemotherapy, etc...). These are more infrequent and usually require specialized centers for diagnosis, being equally irreversible today.
