The causes of infertility are varied and multiple. However, on a pathophysiologic level infertility root cause is normally thyroid/parathyroid dysfunction, low/borderline progesterone, obesity and a pro-inflammatory diet. I normally recommend IVF as a last resort secondary to sometimes very toxic side effects. Fertility acupuncture and the Tao of Fertility book are excellent starting points on one’s fertility journey. Optimizing the aforementioned systems can easily be the cure for fertility issues.
