Remember – the changes to your sex life don't usually last long. There's no medical reason to stop having sex during chemotherapy. The drugs won't have any long term physical effects on your performance or enjoyment of sex. They won't affect your partner either. Cancer can't be passed on to your partner during sex.
It is important to use reliable contraception during treatment. Getting pregnant while either partner is having chemotherapy is not advisable because the drugs may harm the baby.
Even if you or your partner are taking the pill, you should use a condom as an extra safeguard. Using condoms protects your partner from the possible risk that chemicals from the chemotherapy may be in your bodily fluids. Doctors don't think that this is likely, but it has been suggested that chemotherapy can get into vaginal fluids. So as doctors don't know for sure, they advise using a condom during treatment and for a week or so afterwards.
If you have, or have had, breast cancer your doctor may advise you not to take the contraceptive pill because the cancer may be affected by the hormones it contains.
