Endometriosis, one tube and IVF

Hello. Im new here.
I was diagnosed endometriosis and one my fallopian tube is swollen w fluid. My dr prescribed me Norethindrone 5mg for 6 months. After that we're planning to have IVF.  I was also suggested to remove my swelling tube. Is it necessary to remove it?
Personally, i'd rather not having any surgery.
Im late 30s, never been pregnant yet, so time is ticking....
Any advice would be helpful.
Thank you :)
