Reproductive health is an important component of overall health, not only as a key component of adolescent and adult health, but also as a health issue for both sexes beyond the reproductive years, with clear intergenerational implications. The health of the newborn is largely determined by the health of the mother and the health care she previously had access to; it is important for men and women during adolescence, especially during the reproductive years; and although health status varies from stage to stage, it has a cumulative effect throughout life, so experiences at different stages, such as occupations, exposures, and environmental factors, can have a significant impact on future fertility and health. Second, factors affecting male reproductive function In daily life, occupations may expose people to certain chemicals that can have a negative impact on reproductive function. Nearly 50 types of industrial chemicals (including heavy metals) currently confirmed by animal experiments can impair reproductive function in animals, such as lead, cadmium, mercury and dyes. Occupations in high-heat environments, such as casters, smelters, and bread bakers, are twice as likely to cause male infertility as the control group. Third, factors affecting female reproductive function WHO on work- and environment-related health problems in occupations for both men and women, suggesting that women are more likely to work in environments that are potentially health-threatening but unprotected than men. In some developing countries, employed women are often concentrated in labor-intensive factories (e.g., textiles, sewing, electrical appliances, etc.), where conditions are poor and exposure to carcinogenic chemicals is common, or where health is affected by excessive noise, heat, humidity, physical stress, excessive eye use, and allergies. Many industrial substances and agricultural compounds, as well as ionizing radiation, can cause sterility, miscarriage, congenital disabilities and genetic diseases. According to the WHO 1980~1986 survey information provides the following possibilities. 1. Substances that may cause menstrual disorders (1) Organic dyes: such as dyes containing aniline. (2) Organic benzene preparations (shoe industry): benzene, toluene, xylene. (3) Petroleum: petroleum, chlorinated hydrocarbons (rubber manufacturing industry) (4) silicone varnish (electrical insulation industry). (5) benzene and derivative compounds: benzene, urea, formaldehyde, trichloroethylene. (6) Ethylene oxide and inorganic mercury. 2, may have side effects on female fertility treatment and drugs (1) cytotoxic therapy: often cause amenorrhea and anovulation. (2) Steroid drugs: oral contraceptives, estrogen, progestin. (3) Psychostimulant drugs: Drugs for schizophrenia may cause hyperprolactatemia. (4) Antidepressants: tricyclics and monoamine oxidase agents can also cause hyperprolactatemia. (5) Antihypertensive drugs: Risperdal or methyldopa can cause hyperprolactatemia. (6) Gastrointestinal drugs: Gastrodia and perphenazine can also cause hyperprolactatemia.
