My husband used Efudex cream (Fluorouracil 5%) on a few pre-cancerous spots on his face 2x per day, for four weeks back in March. We would like to start trying to conceive again but not sure how long we need to wait after using this cream. All product information says not to use if pregnant or wanting to become pregnant, but doesn't give time frames.
Can you please advise how long it takes for his sperm to no longer be impacted by the use of Efudex cream? When can we starting trying to conceive again?
