Layne Kilpatrick on Instagram: "Female dogs in polyester pants? Yep, that actually happened—and what researchers discovered might just make you rethink your wardrobe. A 2008 study showed that polyester created an electrostatic field around hormone-sensitive areas in dogs, lowering progesterone and tanking fertility—even with artificial insemination. Meanwhile, cotton and wool? 100% pregnancy success rate. Now, I’m not saying your leggings are making you infertile… but if it affects other mammals, and we’re mammals… you do the math. Polyester, spandex, chemical treatments—all layered over your pelvis. Might be time to go natural."
