Male thermal contraception is a daily practice. If you’ve forgotten to wear it for 24 hours or more, it is advised to use another contraception method. Have a new seminogram done a month later. Depending on the results and with your doctor’s approval, you can start using male thermal contraception alone again.
If you lose your thermal ring, the same problem will arise.
This is why it is recommended to always have 2 thermal rings on hand.
