Climate change, microplastics, and male infertility

Area of Science:

• Environmental Science
• Reproductive Biology
• Toxicology

Background:

• Global semen quality is declining, with unknown causes.
• Emerging research suggests environmental factors may play a role in male infertility.

Purpose of the Study:

• To review recent findings on the association between environmental changes and male infertility.
• To explore the impact of climate change, pollutants, and endocrine disruptors on male reproductive health.

Main Methods:

• Literature review of recent scientific studies.
• Analysis of associations between environmental exposures and male fertility parameters.

Main Results:

• Heat stress from climate change negatively impacts spermatogenesis and sperm counts.
• Airborne particle pollution and microplastics show negative associations with sperm production.
• Endocrine disrupting chemicals are under investigation for their links to male fertility issues.

Conclusions:

• The exact cause of declining male fertility remains unclear.
• Climate change, environmental pollutants, and endocrine disruptors are proposed contributing factors.
• Further research is necessary to elucidate these environmental associations with male infertility.
