Legs up in the air, pillow under back for 20mins after sex? Eating lots of orange veg to regulate your hormones/ensure ovulation? Plan something exciting for after sex like a Chinese/wine so it’s a double win? Good luck x
Get him on coq10 as Ubiquinol, NAC and a good multi with zinc. That will improve sperm quality. My husband is 41 and he took those and we conceived. We also took omega 3 and vitamin D.
