Hi
I looked at your three SA results and depending on your age and your own fertility status it may be worth trying supplements and see if you get lucky (that's in my humble opinion and I"m not a doctor...)
I deal with make factor and have done hours of research on medical journals. My dh's motiliy has doubled, but no pregnancy so far

Here's a list of commonly found suggestions (it's actually an old copy-paste from somebody else's very thorough post, to give due credit)
Vit C - 1000mg time release
-Zinc 45mg
-CoQ10 30mg
-Vit E 800iu
-L-arginine 500mg
-acetyl-L-carnitine (fumarate preferred)
-B12 - 1000mcg
-omega 3 FA's
-lycopene 17mg - 8 oz. of V8 per day
-Pycnogenol 100mg
-selenium 400mcg
-folic acid
-milk thistle
-PC-95 (proanthocyanidin)
-Green Tea -
Ginger 1000mg/day
Asian Ginseng
My dh is also on astragalus and I think it helps too. Also follow the basic recs: no tights underwear or pants, no hot baths, keep stress low, no smoking/drugs etc...
good luck. I dont check this forum super regularly so if you have questions pm me.
