Wildfire Smoke May Impact Male Fertility, Study Finds

As wildfires become more common across the United States,a new study suggests that increased exposure to smoke may make it harder for some couples to conceive.
That’s because wildfire smoke may compromise sperm quality in men undergoing fertility treatments, according to the study.
“As we see more frequent and intense wildfire events, understanding how smoke exposure impacts reproductive health is critical,” said Tristan nicholson, MD, PhD, an assistant professor of urology at the University of Washington school of medicine and a reproductive urologist at the UW Medicine’s Men’s Health Center.
For the study, researchers examined semen samples from 84 men in the seattle area who provided sperm for intrauterine insemination (IUI) procedures between 2018 and 2022. IUI, also called artificial insemination, is a fertility procedure where specially prepared sperm is placed directly in a woman’s uterus while she’s ovulating, with the goal of increasing the chance of pregnancy.
All of the study participants provided semen samples before and after exposure to wildfire smoke. There were major fires in the Seattle area in 2018, 2020, and 2022.
Sperm Quality Declined After Wildfires
Sperm samples collected after the wildfires were considerably poorer in quality than samples taken before exposure,according to findings published in the journal Fertility and Sterility.
Wildfire exposure was associated with:
- Declines in total sperm count,or the total amount of sperm released during ejaculation
- Decreased total sperm concentration,or how much sperm is in a milliliter of semen
- Reductions in total progressively motile sperm
Understanding the Impact on Sperm Parameters
The study specifically measured several key sperm parameters. Thes parameters are crucial indicators of
