Effect of posture and clothing on scrotal temperature in fertile men.
Plain-language summary
This study set out to see how posture and clothing affect scrotal temperature in fertile men. It tested 13 men in different positions (standing, seated with legs apart, seated with legs crossed, and supine) while naked and clothed, measuring scrotal temperature in each. Standing naked kept the scrotum coolest, while clothing raised scrotal temperature in all positions. Sitting with legs crossed was especially warming, even when naked, and its effect lingered into the next position.
Key findings
- Standing naked kept the scrotum coolest.
- Clothing raised scrotal temperature in all positions.
- Sitting with legs crossed warmed the scrotum as much as clothing in other positions.
- The warming effect of sitting with legs crossed persisted into the next position.
How to analyze the study yourself
- Study type
- Clinical trials test interventions in a controlled setting, which helps isolate cause and effect, but small sample sizes can limit how broadly the findings apply.
- Population
- The study included 13 fertile male volunteers.
- Funding
- Not reported
- Takeaway
- This study found that standing naked kept the scrotum coolest, while clothing and sitting with legs crossed raised its temperature. If you are trying to conceive, it may be worth standing more often and avoiding tight clothing or sitting with legs crossed.
