What are the symptoms if you have low progesterone?

Pregnancy needs progesterone for its development. In addition to the endometrial changes, progesterone also acts on the uterine muscle, relaxing it to improve pregnancy growth inside it.

On the other hand, uterine immune function suppression must also occur during pregnancy to prevent the body from reacting against the pregnancy. If not, the mother’s antibodies will attack the pregnancy, stopping its development. We have seen that progesterone also participates in uterine immunoregulation to facilitate the embryo’s proper development.

During the initial stages of pregnancy, progesterone secretion directly depends on the corpus luteum, which stays in the ovary after ovulation. As the pregnancy develops, the placenta gradually takes on the production functions of hormones like progesterone in order to completely rely upon it from the third month of gestation.

Taking into account all of the above, progesterone’s importance on pregnancy is obvious and its administration during assisted reproduction treatments is necessary.
