Study links vaping to smaller testicles, decreased sperm count, and lower sex drive.
Vaping Linked to Negative Effects on Male Reproduction, Study Finds
A new study conducted in Turkey has revealed concerning findings about the impact of vaping or e-cigarette use on male sexual health. Published in the Revista Internacional de Andrología, the study highlights the potential dangers of the aerosol produced by e-cigarette products.
The research, which involved male rats, examined the effects of both vaping and conventional cigarette smoking on sperm production, testicle appearance, and stress markers in blood and genitals. The results showed that both forms of inhalation had detrimental effects on male reproductive health, with conventional cigarettes being even worse than vaping.
“It should be considered that although [e-cigarette] liquid has been introduced as harmless in smoking cessation studies, it could increase oxidative stress and cause morphological changes in the testicle,” the researchers wrote. “To be a safe option in smoking cessation studies, its effect on people needs to be enlightened.”
The study found that rats exposed to e-cigarette vapor had a sperm potency of 95.1 million sperm per milliliter, while rats exposed to conventional cigarette smoke had 89 million sperm per milliliter. The control group, which was not exposed to either, had 98.5 million per milliliter. Additionally, approximately 62% of rats in the vaping group experienced negative physical impacts on their testicles, including structural changes, decreased sperm production, cell death, and tissue atrophy.
Vaping has become a popular trend, particularly among young people. A recent study revealed that in 2019, 5 million children aged 12 to 17 in the U.S. used e-cigarette products, and despite efforts by the Food and Drug Administration, these numbers have not decreased. The Centers for Disease Control and Prevention reported that in 2022, 2.55 million middle school and high school students were current users of e-cigarette products. Furthermore, the CDC recorded that in 2021, approximately 14.9 million U.S. adults were e-cigarette users.
This Turkish study supports the findings of a previous Danish study from 2020, which also linked daily e-cigarette use among men to lower sperm counts. However, the authors of the Turkish study acknowledge the need for further research on humans to fully understand the implications.
