This document discusses reproductive health issues and environmental pollutants that can impact fertility. It notes that reproductive health refers to diseases and conditions affecting the male and female reproductive systems, including birth defects and infertility. Two major pollutants discussed are lead and mercury. Lead is found in paint, gasoline, cosmetics and some spermicides, and long-term exposure can decrease sperm count and quality as well as potentially cause birth defects. Mercury is present in batteries, appliances and lamps, and exposure has been linked to birth defects, neurological issues, and reduced sperm motility and count leading to infertility. The document also briefly discusses abortion and its history.
