Hi Anusha, thanks for the query. Let me help you understand few things. Any external procedure carried out on our body has to be considered seriously and carries a risk of infection. Your fever could be due to any viral or bacterial infection unrelated to the procedure carried out or any mild infection due to embryo transfer which is very unlikely as you don t have any other pelvic symptoms. You have been advised rightly to take paracetamol to keep your temperature low. Do hydrate yourself well and get plenty of rest. Regarding your question about chances of conception, there are no direct studies done in humans how fever affects fertilisation and embryo implantation. The animal studies done shows it possibly affects egg and sperms, fertilisation and embryo implantation. With such equivocal evidence, all that one can do is treat fever effectively. I suggest you to take care of yourself and be hopeful. Good luck.
