If polyester can do this to sperm count (+ testicular size), how else is it harming your body? STUDY DETAILS: On this @Detox Your Dome podcast episode, we discussed 3 studies that demonstrated polyester lowering sperm count to 0 and progesterone count to 0 - temporarily. The first was a clinical study done to see if polyester could act as a contraceptive (sounds crazy right? Keep reading). 14 men wore a polyester sling (similar to wearing polyester underwear) for 12 months. The findings showed: - All of them were temporarily infertile - Sperm levels lowered to 0 - Testicular shrinkage - No pregnancies However, once they stopped wearing this polyester piece, sperm levels went back up to their pre-test levels. The findings suggest: - The polyester sling created an electrostatic field across the body causing friction, potentially disrupting testicular function - Polyester blocks airflow, resulting in disordered ability to regulate temperature (aka increasing temperature), impairing sperm production The 2nd and 3rd studies were done on dogs. One with male dogs dressing them in polyester underpants and measuring sperm levels - which went to 0 (along with lowering testicular size) and the other with female dogs but measuring progesterone, which also went to 0. The female dogs were unable to ovulate and thereby unable to get pregnant when wearing the polyester. An electrostatic field was detected on the dogs wearing polyester. Suggesting, again, that polyester is creating an ‘electrostatic field’ that inhibits the hormone function. However, the effect proved to be reversible in both studies. And it is important to note, in the dog studies, some were dressed in cotton underpants - which showed *no* significant changes in sperm, testicular, or ovarian health. All studies warrant further investigation; however, the bottom line is that polyester is not something you want to wear - especially as underwear. Instead, opt for natural fibers like organic cotton or merino wool. Check out my top recs on my site for both men and women!
