Acupuncture has been shown to affect hormone levels by promoting the release of beta-endorphin in the brain. This affects the release of gonadotrophin releasing hormone by the hypothalamus, follicle stimulating hormone from the pituitary gland, and oestrogen and progesterone levels from the ovaries (Ng 2008, Huang 2008, Lim 2010, Stener-Victorin 2010).
Blood flow to the ovaries
Acupuncture improves blood flow to the ovaries (Stener-Victorin 2006, Lim 2010), thus improving the environment for the ovarian follicles. It increases blood flow to the uterus (Stener-Victorin 1996, Huang 2008), improving the thickness of the endometrial lining to increase the chances of embryo implantation.
Treatments for PCOS
Acupuncture reduces the activity of the sympathetic nervous system, and has been shown to reduce the number of ovarian cysts, stimulate ovulation, enhance blastocyst implantation and be able to regulate menstrual cycles in women with PCOS (Stener-Victorin 2000, 2008, 2009, Zhang 2009). There is also evidence that acupuncture may assist with reducing secondary effects such as obesity and anorexia (Lim 2010).
