Final answer:
Endocrine disruptors can greatly affect males by causing altered reproductive development, including impaired heart function, testicular atrophy, and prostate enlargement. These disruptors can interfere with hormones at low doses, leading to significant changes in reproductive health and decreased fertility.
Step-by-step explanation:
The major effects of endocrine disruptors in males can include altered reproductive organ development, such as impaired heart function, testicular atrophy, and prostate enlargement. These can lead to decreased fertility in males. Furthermore, exposure to certain endocrine disruptors has been linked to the presence of eggs in male fish testes (ova-testis), indicating that these substances can cause severe and sometimes irreversible changes in the reproductive systems of exposed wildlife and potentially humans.
Endocrine disruptors interfere with the body's hormonal systems and may be found in a variety of substances, including pharmaceuticals, pesticides, and plastics. These disruptors can have profound effects at very low doses, altering gene expression and hormonal balance. High-level exposure to endocrine disruptors is undoubtedly serious and can be directly lethal, but even low-level exposure can have significant, albeit less immediately dramatic, effects.
