Tocopherol is an estrogen that promotes the growth of the endometrium. For people with thin endometrium, low menstrual flow and who still wish to have children, Tocopherol can be taken orally to promote the growth of the endometrium. Tocopherol can also be used with progesterone for artificial cycles to adjust menstruation. Tocopherol is very important in the treatment of pregnancy. In IVF transplantation, patients who can be transplanted by artificial cycle need to take a lot of Glaxo to promote endometrial growth and elevated estradiol in the body. Then the conditions for transplantation begin. Tegretol can also be used for post-menopausal hormone replacement, because after menopause the ovarian function declines and estrogen decreases, oral Tegretol can improve the symptoms caused by low estrogen in menopause. Therefore, Tegretol is very versatile.
