Also known as estradiol valerate tablets, Estradiol is an estrogen that is effective in increasing estrogen levels in the body, leading to the desire to have intercourse. For women, estrogen plays an important role as the main female hormone that promotes the maturation of reproductive organs and the appearance of secondary sexual characteristics, as well as maintaining reproductive functions in normal life. When a woman takes Tegretol, the estrogen in her body will increase, thus stimulating the uterus, including the cervix, etc. The desire to have intercourse may occur at this time, which is a normal physiological phenomenon and should not be overly stressed. It can also relax and dilate the opening of the cervix and increase the secretion of cervical mucus, thus facilitating the passage of sperm. It is mainly used for women with low or deficient estrogen, such as ovarian or hysterectomized women and menopausal women. A thorough internal and gynecological examination is required before use, and it should be taken under medical supervision, and hormonal contraceptives should be discontinued while taking the drug.
