Studies confirm that male sperm counts are declining, and environmental factors, such as pesticides, exogenous estrogens, and heavy metals may negatively impact sperm production. An estimated six percent of adult males are thought to be infertile and an estimated 15 percent of couples attempting their first pregnancy will have difficulty conceiving.
There are specific on specific nutritional and environmental factors that contribute to a man's fertility, but also other factors and conditions including (but not limited to):
- Endocrine abnormalities
- Prescription drugs (anti-seizure medications, sulfa drugs, some antibiotics and steroids)
- Previous infections
- Liver disease
- Autoimmune conditions
In addition to these conditions, evidence suggests environmental reasons contributing to poor sperm quality, including exposure to chemicals, pesticides, heat, radiation, heavy metals, and electromagentic forces (a nearby cellphone).
There are many nutritional interventions for increasing sperm count, mobility, and motility. Often addressing the underlying medical conditions, environmental exposures, and stress can increase a man's fertility.
