You may be exposed to reproductive hazards through contact with your skin, breathing them in, or swallowing them. This can happen anywhere, but it is more common in the workplace or at home.

The possible health effects of reproductive hazards include infertility, miscarriage, birth defects, and developmental disabilities in children. What type of health effects they cause and how serious they are depends on many factors, including
- What the substance is
- How much of it you are exposed to
- How it enters your body
- How long or how often you are exposed
- How you react to the substance
How can reproductive hazards affect men?
For a man, a reproductive hazard can affect the sperm. A hazard may cause a problem with the number of sperm, their shape, or the way that they swim. It could also damage the sperm's DNA. Then the sperm may not be able to fertilize an egg. Or it could cause problems with the development of the fetus.
How can reproductive hazards affect women?
For a woman, a reproductive hazard can disrupt the menstrual cycle. It can cause hormone imbalance, which can raise the risk of diseases such as osteoporosis, heart disease, and certain cancers. It can affect a woman's ability to get pregnant.
A woman who is exposed during pregnancy can have different effects, depending on when she was exposed. During the first 3 months of pregnancy, it might cause a birth defect or a miscarriage. During the last 6 months of pregnancy, it could slow the growth of the fetus, affect the development of its brain, or cause preterm labor.
How can reproductive hazards be avoided?
To try to avoid reproductive hazards,
- Avoid alcohol and illegal drugs during pregnancy
- If you smoke, try to quit. And if you are not a smoker, don't start
- Take precautions if you are using household chemicals or pesticides
- Use good hygiene, including handwashing
