The gonads, or sex glands, comprise the ovaries in women and testes in men. The ovaries produce eggs and also secrete hormones, mainly oestrogen and progesterone. Similarly, the testes produce sperm and the hormone testosterone. Oestrogen controls the female secondary sexual characteristics such as enlargement of the breasts, growth of pubic hair and deposition of body fat. Progesterone is vital in pregnancy as it prepares the uterus for implantation of the egg cell.
The reflexes for these and related organs are found near the ankles on the inside of the feet, just below the angular bone. The same reflex areas are also located on the arms, near the wrist. The ovaries and testes are on the outer edge, while on the opposite, inner edge, are the reflexes for the uterus, penis and prostate.
For any disorders that might involve the ovaries or testes, it is also useful to massage other systems such as the brain, other endocrine glands, the circulation and liver.
