Study warns of common food substance that may impair male fertility
New York - (Saba): A new study has raised serious concerns about sucralose, the popular artificial sweetener, as findings indicate it may negatively affect male fertility. In the study, published in the journal Environmental Health Perspectives, researchers administered doses of sucralose to male mice over a period of two months and observed decreased sperm vitality, damage to testicular tissue, and hormonal disturbances. These findings are particularly significant in light of the escalating global fertility crisis. The shocking irony is that recent studies show that men are responsible for nearly half of infertility cases, with sperm counts declining by more than 50% in Western countries since the 1970s. However, experts caution against over-interpreting these results. Dr. Dan Nayot, a reproductive endocrinologist, points out that the research was conducted on rodents at high doses, which calls for caution when generalizing the results to humans. He also explains that the actual decline in testosterone levels over recent decades may be in the range of 20-25%, a worrying percentage, although lower than current estimates. There are multiple factors behind this silent health crisis, with unhealthy lifestyles playing a major role. Smoking, excessive alcohol consumption, obesity, and lack of physical activity all contribute to the decline in male reproductive health. Experts emphasize that the sperm production process, which takes between two and three months, is highly sensitive to these external influences. In the face of this health challenge, experts recommend a preventative approach based on improving overall lifestyle. Dr. Nayot emphasizes the importance of good sleep, regular physical activity, and a balanced diet, along with the possibility of using some fertility-boosting nutritional supplements such as coenzyme Q10, zinc, and vitamin E. He also notes that sperm health largely reflects an individual's overall health, making sperm care an indicator of overall health. Scientists are now seeking to conduct further research to confirm these findings in humans. In the meantime, it seems wise to follow the principle that prevention is better than cure and to search for safer natural alternatives to artificial sweeteners. Whatsapp Telegram Email Print

Popular artificial sweetener may sabotage fertility: alarming new study
No sugarcoating this deflating news. New research in the journal Environmental Health Perspectives is raising concerns about sucralose — a widely used artificial sweetener sold under the brand name Splenda — suggesting it may negatively affect male fertility. 3 New research suggests sucralose — a widely used artificial sweetener — may negatively impact male fertility. Laurentiu Iordache – Advertisement Researchers administered doses of sucralose to male rats over two months, finding that the exposure led to decreased sperm viability, damage to testicular tissue and hormonal disruptions. Translation? Splenda might just be sinking your swimmers. Previous studies have explored links between artificial sweeteners and reproductive health, though findings have been mixed and often inconclusive. Advertisement While this study's conclusions are noteworthy, there were limitations. The research was conducted on rats, so the results may not directly apply to humans. Additionally, the researchers noted that the amount of sucralose consumed by the rats probably exceeds that of human intake. Advertisement The Post reached out to Splenda's manufacturer for comment. The findings warrant further investigation, especially since infertility is a rising global health issue — with an estimated 12% to 15% of US couples struggling to conceive. It may come as a surprise, but some studies indicate men are responsible for as many as half of infertility cases. Some research even reports that sperm counts in Western countries have dropped by more than 50% since the 1970s.

Getty Images Dr. Dan Nayot, a reproductive endocrinologist, infertility specialist and chief medical adviser at testing and supplement company Bird&Be, told The Post that the statistic is likely not that high, but it's still problematic. 'Research shows a real decline in testosterone levels over the past few decades — likely closer to 20–25%, not 50% — but that's still a significant issue and shouldn't be dismissed,' Nayot said. 'Testosterone plays a critical role in sperm production, so lower levels can lead to reduced sperm quality and impaired fertility.' While the reasons for the drop are not entirely clear, experts point the finger at some of the same factors contributing to the obesity epidemic. 3 To protect your family jewels, one infertility specialist recommends 'adopting healthier habits — such as improving sleep, increasing physical activity, quitting smoking and maintaining a balanced diet.' Getty Images/iStockphoto 'Sperm production is a continuous process, with mature sperm developing over approximately two to three months,' Nayot said. Advertisement 'This process is highly sensitive to lifestyle factors. Research consistently shows that smoking, excessive alcohol consumption and obesity — to name a few — impair sperm quality. In fact, sperm health is often considered a marker of overall wellness, underscoring the importance of prioritizing your physical health.' To protect your family jewels, Nayot recommends 'adopting healthier habits — such as improving sleep, increasing physical activity, quitting smoking and maintaining a balanced diet.' He also suggests taking certain supplements — such as coenzyme Q10, zinc, vitamin E, L-carnitine, folate, selenium and DHA — to help swimmers stay afloat. Based on this study, it also couldn't hurt to find your sweet release elsewhere!
