Sperm count - IUI or IVF

I just did my first <a href="https://glowing.com/glow-fertility-program">IUI</a> and our count was 8M pre- and 2.1M post-wash. This is lower than previous analyses despite vitamins, etc. The doctor didn't say whether it was good or bad, but judging from research success rates are so low. Has anyone had success or other experiences with low counts and motility? Has anyone been advised to go straight to <a href="https://glowing.com/glow-fertility-program">IVF</a> with low counts and motility? I'm starting to feel like <a href="https://glowing.com/glow-fertility-program">IUI</a> is a waste for us. My doctor hasn't advised <a href="https://glowing.com/glow-fertility-program">IVF</a> yet, but she doesn't do the procedure herself so wondering if that impacts her advice. Thank you all in advance!
