The last time we TTC dh was taking Fertilaid for Men, Countboost and MotilityBoost. He had borderline numbers on count and motility and abysmal morphology. We had been trying for two years without success and then got a bfp after one month of him taking this combo.
This time around, dh does not want to take all of the tablets, so I've had to modify what he takes. I have him on bulk powdered supps and liquid extracts that can be mixed in liquid. He's now taking:
Vitamin C
Zinc
L-Carnitine
Folic Acid
Ginkgo Biloba
I hope these do the trick, although I sometimes wonder whether there's some other magic ingredient he needs to try. Vitamin C seems especially promising.
