Need opinions please !

So my husband and I have been trying for 2 almost 3 years to have a baby! Well we finally decided to see a doctor and found out that his sperm count movement and volume were extremely low. Well with help from the doctors it’s back to normal, well we went to my OBGYN to see why we still weren’t, found out I have a titled uterus and could possibly have endometriosis but won’t know without surgery. So he wants us to try ourselves 3 more times. So in the mean time does anyone have any tips, ideas, or has had this problem themselves? If so what are you doing? Is there something I can eat more of drink more of?
