Area of Science:

  • Reproductive Medicine
  • Andrology
  • Environmental Health

Background:

  • Male infertility is a growing concern.
  • Lifestyle factors, including smoking, may affect semen quality.
  • Understanding the impact of smoking on fertility is crucial.

Purpose of the Study:

  • To investigate the effect of cigarette smoking on conventional semen parameters.
  • To assess whether smoking impacts sperm volume, count, motility, or morphology.

Main Methods:

  • Retrospective study of 90 healthy male patients from an infertility clinic.
  • Comparison of semen parameters between 40 smokers and 50 non-smokers.
  • Analysis of data stratified by age groups.

Main Results:

  • Smokers exhibited significantly lower sperm volume compared to non-smokers.
  • No significant differences were observed in total sperm count, sperm count/ml, total motility, progressive motility, or morphology.
  • Age did not alter the observed effects of smoking on semen parameters.

Conclusions:

  • Cigarette smoking appears to negatively affect sperm volume.
  • Smoking does not seem to detrimentally impact other key semen parameters or spermatogenesis.
  • Further research may be needed to explore the mechanisms behind reduced sperm volume in smokers.
