Sperm can easily pass through thin, breathable fabrics like cotton or microfiber. However, tighter-fitting materials like spandex or nylon can create more friction and may be less conducive to sperm movement. It's also important to note that the type of underwear worn can impact temperature regulation, which can affect sperm health. Overall, looser-fitting styles like boxers are generally more favorable for sperm viability.
