Suspected endometriosis

My RE has his best guess with I have endometriosis, but isn't recommending laparoscopy. We're thinking about <a href="https://glowing.com/glow-fertility-program">IVF</a>. Is this odd that he doesn't want to do sugery first? Will <a href="https://glowing.com/glow-fertility-program">IVF</a> be successful with endo?
