Which factor is least likely to affect a man's sperm analysis results?

The factor least likely to affect a man's sperm analysis results is the treatment he received for previous prostatitis. While prostatitis can temporarily impact fertility and sperm quality during the inflammation phases, effective treatment often resolves such issues. Once a man has undergone appropriate treatment for prostatitis, his sperm production and quality typically return to baseline levels, minimizing any long-term effects on sperm analysis.

In contrast, regular cycling as a mode of transportation can have varying effects on sperm quality due to potential pressure on the genitals and temperature elevation. Medication for hypertension, depending on the specific drug, may have side effects that can affect erectile function or sperm production. Caffeine consumption has been studied for its potential effects on sperm motility and overall reproductive health, making it a more relevant factor when considering sperm analysis results. Thus, treatment for previous prostatitis is less likely to have lasting impacts on sperm analysis compared to these other factors.
