Acupuncture Prevents Uterus Contractions
The uterus can sometimes contract, which can be bad for a foetus, as contractions could potentially push the foetus off the uterus wall, causing a miscarriage.
Contractions are caused by the hormone oxytocin, which is released by the pituitary gland.
Acupuncture has also been shown to reduce uterine contractions, which can propel the embryo out of the uterus.
Acupuncture can also aid implantation and pregnancy in other ways. Stress stimulates the sympathetic nervous system, which causes constriction of ovarian arteries. Acupuncture inhibits this sympathetic activity, improving blood flow to the ovaries enhancing the environment in which ovarian follicles develop.
It also increases blood flow to the uterus, improving the thickness of the endometrial lining and increasing the chances of embryo implantation.
