Men abandon polyester underwear for fertility reasons

A study reveals that men are ditching polyester underwear and briefs to safeguard their fertility. They are opting for cotton or wool alternatives perceived as healthier. This shift stems from chemicals in polyester linked to reduced sperm quality.

According to a study published in The Wall Street Journal, underwear made from polyester fabrics, which contain plastic, harbors chemicals associated with adverse effects on male sperm. Scientists note that invisible microplastics often appear in air, food, and water, carrying contaminants that impact human organs. These can lead to diseases such as cancer, vascular degeneration, heart conditions, and cellular damage.

Tight, stretchy polyester underwear has gained significant popularity among young men. Health expert Jaime Knopman stated, “If it's a plastic underwear that's very tight around the scrotum, then it reduces the quality of male sperm, the quantity of that sperm, and affects men's fertility.”

Alex Robles, a fertility specialist and lecturer at Columbia University, emphasized the need for further research on fabric types and their impacts. He added, “Wearing tight underwear, sitting for long periods, or cycling increases temperature levels and has been linked to reduced male sperm quality in previous studies.”

Some men have reported improved sperm quality when avoiding constricting underwear. Researchers advise men to choose loose-fitting options, avoid excessive heat, consume mineral-rich foods, and limit smoking and alcohol intake to enhance reproductive health.

Researchers at NYU Langone Health reported detecting microplastics in prostate tumor tissue from a small group of men undergoing prostate removal surgery, with average concentrations about 2.5 times higher in tumor samples than in nearby noncancerous tissue. The team says the findings, scheduled for presentation Feb. 26, 2026, at the American Society of Clinical Oncology’s Genitourinary Cancers Symposium, add early evidence that microplastic exposure could be relevant to prostate cancer but do not establish cause and effect.

A clinical trial suggests that men who ejaculate within 48 hours before providing sperm samples for IVF achieve higher ongoing pregnancy rates than those who abstain longer. The study, involving over 450 men, found a 46% success rate in the shorter abstinence group compared to 36% in the longer one. Experts note potential benefits but call for further research on live births and other factors.

It highlights ongoing debates between natural and synthetic fiber impacts.

A new systematic review indicates that microplastics could trigger brain inflammation and damage through several biological pathways, potentially worsening neurodegenerative diseases like Alzheimer's and Parkinson's. Researchers from the University of Technology Sydney and Auburn University identified five mechanisms linking these tiny plastic particles to brain health risks. Adults ingest about 250 grams of microplastics annually from various everyday sources.

Around 40 participants aged 18-39 are involved in a 12-week internet-based program. The study is expected to include a total of about 250 people.

Researchers at the University of Michigan have discovered that common nitrile and latex lab gloves release particles resembling microplastics, potentially inflating pollution estimates. The study, led by Madeline Clough and Anne McNeil, traced contamination to stearates in the gloves during sample preparation. Switching to cleanroom gloves could reduce false positives significantly.
