The preconception test requires relaxation, good rest, avoiding overwork and staying up late to prevent the hormone level of the body from being affected, quitting smoking and drinking, eating a light diet, avoiding greasy and indigestible food, and avoiding sexual intercourse before the test. Pre-conception check-ups mainly check whether the reproductive system of the couple is functioning normally, whether the hormone level in the body is normal and whether it is suitable for pregnancy at present. During the preparation period, couples should avoid exposure to harmful substances, enhance the intake of nutrients, and take folic acid to effectively prevent neural tube defects in the fetus. Pay attention to the combination of work and rest, maintain local hygiene, and avoid pelvic inflammatory disease, which can seriously lead to pelvic adhesions and affect the fertilization of eggs, thus causing infertility.
