Alright ladies! This is a 2-part question!

My dh is in the military and we just found out he will be deploying for at least 5 months starting in May. We have been trying to conceive for 14mo, with one natural pregnancy that ended in mc. DH's sperm is decent; a bit low in count but enough to give a good count for iui. We just found out my right tube doesn't reach the ovary, so we are just working with the left side. My RE suggested doing more iui's, but now of course, we face an issue with DH not being here.

So, do you think it's worth it to freeze sperm so we don't lose another span of time? Also, does anyone have a ballpark of how much freezing sperm costs?
