Infusion will affect the delay of menstruation, this is because women’s menstruation is not only affected by the estrogen and progesterone secreted by the ovaries, but also by the hormones secreted by the hypothalamus and pituitary gland. Infusion indicates that the patient has a disease at this time, after the disease will lead to delayed menstruation, in addition to some environmental changes and the patient has a mental shock, or excessive tension, may inhibit the secretion of pituitary gonadotropins, which will lead to delayed menstruation. The same applies to infusion, so when women of childbearing age find that their periods are delayed, it is important to rule out the possibility of pregnancy. If pregnancy is not the cause, then the gonadotropin levels in the body should be taken into account, and further tests and treatment can be given at the hospital.
