Should I tell them I'm having surgery in a couple of weeks

I'm having a Laparoscopy in a couple of weeks. Specifically as part of my infertility investigations. I've never been like, big on including my family in my life in this regard (medical things, baby making things). They don't know we've been TTC for a couple of years already.

Anyway. I don't really want them involved in my business but should I tell them I'm having a procedure done? I just don't want all the questions. I will probably be fine by the next time I have to see them anyway.
