The congenital condition is closely related to the condition of the parents. People may inherit both positive and negative constitutions. The congenital condition may greatly influence the reaction of the body to pain in later life. TCM places some importance on the conditions of the parents immediately before pregnancy. In general, they should ensure they are in their best physical health and a good emotional state while preparing for pregnancy. They are advised to complete copulation when both partners are in orgasm, and conversely to try to avoid the woman getting pregnant when under stress or during physical sickness. This important advice is widely given at present in China because of the one-child policy. For young couples who want a pregnancy, a general physical check-up is carried out so as to try to get as healthy a baby as possible.
