You've got to have some bedroom Funtime within 2 days of egg collection anyway otherwise chance of sperm dna fragmentation is higher so depends on how many days of stims you are doing - mine is only 10'days and don't want to tire his little swimmers out so certainly won't be doing it daily (not that we do that normally anyway!)
I think IVF drugs reduce sex drive in my experience. The bloating isn't so sexy either - makes me feel self conscious. I'm more in the mood when I'm unmedicated I think. Anyhow doesn't really answer the question lol
Our clinic never mentioned sex or not to have any/ to use protection while stimming. We had been told none after egg collection until pregnancy test so made the most of the time while stimming in case we didn't get a chance for a while (had planned not to until pregnancy scan if IVF had worked).
