Type A blood is better than Type O blood?

The research that examined whether it was easy to become pregnant for a blood type was announced in U.S.A.
It says that a result, an A type woman were easy to become pregnant in comparison with the O-type woman.
As for the A type woman, there is much ovulation, and it is said that there was little ovulation as for the woman of the O-type when Dr. Edward of the U.S. Albert Einstein College of Medicine investigates it for woman 560 people equal to or less than 35 years old.
Furthermore, it is said that there were more A type women than the O-type woman a hormone controlling the ovary called FSH(Follicle stimulating hormone).
I'm a man and already an adult so I have to accept the responsibility if it is happened. (you know...)
But it goes without saying that I conclude whether lumps it together for a blood type and is easy to become pregnant.
