Women with an endometrial lining of 0.2cm have a very low probability of getting pregnant. Women with an endometrial lining that is too thin need to be actively regulated under the guidance of a doctor, and it is more suitable to get pregnant when the endometrial lining reaches about 0.7-0.8cm. If the endometrium is too thin, it is difficult for a fertilized egg to develop normally and a biochemical pregnancy or spontaneous abortion can occur. A thin endometrium is usually caused by damage to the endometrium due to multiple inductions or miscarriages, or when a woman’s ovaries are not functioning well and the level of estrogen and progesterone secreted is too low to promote the growth of the endometrium, which may lead to infertility. Such women need to see a doctor to further investigate the cause and give appropriate treatment measures under the guidance of the doctor.
