1. Do not have unprotected sex. Sexually-transmitted diseases, such as gonorrhoea and Chlamydia, can damage the sperm-producing cells that block the tubes carrying sperm from the testis to the penis.
2. Avoid pesticides that control pests in the garden and on the farm. Such chemicals can damage the sperm-reproducing organs.
3. Avoid insecticides sprayed to kill mosquito. Such chemicals can damage the sperm- reproducing organs. Therefore, if you must spray your room against mosquitoes, allow at least one hour before going back to the room.
4. Avoid exposure to lead fumes generated in the manufacture of small cell batteries and in bullets. Such fumes can reduce sperm count through their negative effects on the hormones and the testis.
5. Avoid exposure to heavy metals like cadmium from the manufacture of heavy batteries, as they negatively affect the hormones.
