DH sperm analysis

DH (darling husband) has a mid low mobility sperm. 51% of sperm were not moving and only 12% are high grade movement. She said that analysis doesnt indicate infertility but low fertility. 

The dr has recommend the following vitamins (please consult with dr before taking any meds this is what our dr recommend for my DH) 

Vitamin C 500mg twice a day

Vitamin E 200 units per day no more 

Pycnogenol 120mg (amazon) 

CoEnzyme Q10 100mg 

Green Tea one cup per day

Dark Chocolate small piece 70% coco 

DH (darling husband) has been taking it for 2 months now and he says he has more energy and sperm is thicker. Tmi sorry her wakes up "with a tent" and gets  excited easier.
