Many people know that progesterone is a natural hormone in the human body, which can be used to protect the fetus to some extent, so many women will take some progesterone supplements to a greater or lesser extent when they are pregnant. So, we all want to ask, what are the effects of progesterone injection?

Progesterone is a progesterone drug, its effects include: first, promote the growth and development of the uterine lining during pregnancy, which can be conducive to the embryo's implantation. Secondly, it promotes the relaxation of the muscles of the pregnant uterus and reduces its mobility, so that its ability to respond to external stimuli is weakened, and reduces the sensitivity of the pregnant uterus to oxytocin-like substances, thus favoring the growth and development of the fertilized egg in the uterus. Therefore, in many cases, progesterone is the drug of choice for the treatment of preeclampsia. Although it is the drug of choice, but not all cases are able to use progesterone to protect the fetus, it is only applicable to the luteal secretion insufficiency, progesterone deficiency caused by preeclampsia to protect the fetus, and for non-luteal insufficiency caused by preeclampsia is ineffective.

In addition, progesterone can make the mouth of the cervix close, the mucus is reduced and thickened, the sperm is not easy to penetrate; large doses through the hypothalamus of the negative feedback effect, inhibit the secretion of pituitary gonadotropins, thereby inhibiting ovulation, so the main clinical can be used for habitual miscarriage, dysmenorrhea, menstrual bleeding, or blood disintegration, amenorrhea, and so on.
