Could my partner be exposed to Androderm?

Yes, it is possible for another person to be exposed to the Androderm still on the skin after a patch was removed. However, it is unlikely that there will be enough testosterone left on the skin to be a problem. In addition, the film backing on the Androderm patch will prevent your partner from being exposed to the testosterone. It is not necessary to remove the patch when having sexual intercourse, showering or bathing. If you use a topical testosterone gel instead of the patch, some of it could rub off onto your partner in certain situations.
