Based on what I’ve learned, nakaka-buntis ba ang nilabsan sa kamay at towel? Hindi. I think the sperm won’t last long enough on a towel or hand to reach the vagina. For conception to happen, the sperm needs to be deposited directly inside the vagina, especially during the woman’s fertile window. So in your case, kung nag-wipe lang ng towel or kamay, walang danger. But if you're still worried, I suggest discussing this with your OB or family planning expert for more peace of mind
