Hi Tonystark, sex is usually considered safe while on chemo, but unprotected sex does bring in a couple of issues that need to be addressed and your care team are by far the best people answer your question, best wishes with your treatment.
It is not known for sure whether chemotherapy drugs can be passed on through semen. But in case they might, the general advice is to use a barrier method (such as condoms) if having sex during treatment. This applies to vaginal, anal or oral sex.
Generally, doctors advise a barrier method only for the time you are actually having the treatment and for about a week after your treatment. After this, it should be okay to have unprotected sex again.
I hope this helps. Please get back to us if you need any more information or support. You may find it helpful to talk things through with one of the nurses on our helpline. The number to call is Freephone 0808 800 4040 and the lines are open from 9am till 5pm Monday to Friday.
