Semen Parameters and Exposure Risks in Military Males

Area of Science:

• Reproductive medicine
• Occupational health
• Military medicine

Background:

• Military personnel face unique environmental and occupational exposures.
• The impact of these exposures on reproductive function remains largely unknown.
• Understanding these factors is crucial for military health and readiness.

Purpose of the Study:

• To determine the frequency of self-reported exposures among men in the U.S. Military Health System.
• To investigate the association between these exposures and semen parameters.
• To identify potential risks to male reproductive health within the military population.

Main Methods:

• A cross-sectional study analyzed data from 291 men in the U.S. Military Health System seeking fertility care.
• Exposures and semen analysis parameters were collected and analyzed.
• Statistical methods included relative risks and contingency tests to compare groups with abnormal semen parameters.

Main Results:

• Tobacco use was significantly associated with an abnormal total motile sperm count (RR 1.95, P=0.02).
• No other significant associations were found between reported exposures and semen parameters.
• The study included diverse representation from major military branches and ranks.

Conclusions:

• Occupational exposures may impact the reproductive health of military service members.
• Further research is warranted to explore unidentified risks.
• Predeployment fertility counseling is recommended for military personnel due to potential risks.
