My husband had a sperm test done and everything was normal except for his viscosity. It was too high. The doctor acted like we don't really have a chance of conceiving naturally (even with meds for me) without <a href="https://glowing.com/glow-fertility-program">IUI</a>. My husband is unwilling to go that far in trying to conceive another child but he is willing to let me give him meds or diet changes to try to help. I ordered him FH Pro off of Amazon. It is a supplement that is supposed to help sperm. I also saw something about taking mucinex?? Any one have any experience with this?
