Success with IUI and low sperm count

Katie
Has anyone had success with an <a href="https://glowing.com/glow-fertility-program">IUI</a> and a low sperm count? My husband's count is 600,000. 😞 We were told today by a fertility nurse that we wouldn't be candidates for <a href="https://glowing.com/glow-fertility-program">IUI</a> if his count wasn't at minimum 3 million. We are through Kaiser Permanente and they don't offer <a href="https://glowing.com/glow-fertility-program">IVF</a> so we are literally looking at out of pocket for that. Has anyone else heard of not even doing <a href="https://glowing.com/glow-fertility-program">IUI</a> if sperm count is under 3 million? Should we be more aggressive with our request for one? Feeling pretty deflated this evening...
