Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are essential parts of the menstrual cycle. FSH signals that the ovaries should produce follicles, through which an egg will be released. When a follicle is fully mature, a surge of LH signals that the egg should be released, causing ovulation. When levels of FSH and LH are too high, this can interfere with ovulation and conception. Although there are prescription drugs that can assist with balancing hormones, many women choose to use a natural approach, such as yoga, acupuncture or Chinese medicine, to lower FSH and LH levels.
