Is 4 million ever going to be enough to conceive naturally?

Sally

Both my husband and I are 30 and have been trying for 18 months. We found out that he has a severely low sperm count- 4 million in 4ml. He had been taking wellman tablets but now has switched to fertilaid and count boost. I'm trying to remain optimistic but I have a feeling ICSI <a href="https://glowing.com/glow-fertility-program">IVF</a> is our only option. Has anybody else been successful at falling pregnant naturally with an extremely low count. We're due for the second analysis result this Tuesday.
