High Prolactin Levels And Implantation
Does high prolactin level affect embryo implanation?
Recent studies at the Department of Gynaecology, Longhua Hospital, Shanghai University of Traditional Chinese Medicine have shown that prolactin can maintain the corpus luteum during pregnancy by its ability to induce embryo implantation.
Prolactin plays an important role in early pregnancy implantation and pregnancy maintenance.
When there are unusual levels it is closely related to spontaneous abortion.
To complicate this situation is that fact that prolactin is produced not only by the anterior pituitary gland but also by the endometrium. This is called dicidual prolacting and binds to receptors on the fetal chorion and amnion and enters the amniotic fluid in high concentration.
Unlike pituitary prolactin that targets organs from distance, decidual prolactin appears to have direct effects on the uterus, placental membranes and the fetus.
"Prolactin may have an important function during implantation and early pregnancy. Prolactin controls the growth of the trophoblast cells in the endometrium."(Reproduction (2001) 121, 197–205).
The trophoblast cells form the outer layer of the embryo, which provide nutrients to the embryo and then form much of the placenta.
So, as you can see the role of prolactin in pregnancy is controversial. Earlier studies show how high prolactin levels cause recurrent miscarriage.
However, more recent studies have shown a beneficial role of prolactin in embryo implantation.
There are many things you can do to help balance high prolactin levels. Herbal remedies can be effective in most cases. Vitex agnus castus has been studied for this positive effects on women who have luteal phase defect.
An herbal balancing formula can really help maintain high prolactin levels at bay by managing the levels of the other hormones released by the pituitary gland like FSH and LH.
Vitex has a direct action on the pituitary gland and stimulates the release of LH hormone, thus supporting the corpus luteum and progesterone production during the luteal phase of the menstrual cycle.
By supporting progesterone, Vitex is known to lengthen the luteal phase and facilitate pregnancy, preventing early miscarriage.
