Millions of men around the world suffer problems in the bedroom due to ageing, obesity and illnesses like diabetes.
The blood rush triggered by hormones may be the key to a strong and long lasting erection that can improve performance in bed, but there’s more to it.
In a new development, scientists have discovered there could be another surprising reason why so many struggle to perform: their blood type.
A study says that while blood flow is definitely a factor, the type of blood in a person also plays a part in the kind of erection they have.
The study shows men with blood types A, B or AB are up to four times more likely to suffer impotence, or erectile dysfunction, than men who have blood type O.
The findings are potentially significant as it's estimated more than half of all men carry A, B or AB blood.
Roughly 44 per cent have type O.
The link is explained since AB type blood has been known for a risk of heart diseases and blood clots. Previous studies have also mentioned that erectile issues may indicate heart diseases that might strike in a few years.
A and B type blood also have high amount of adhesion molecule which can cause plaque in arteries, hence affecting blood flow. This affects erection more since arteries in the penis are narrow as compared to the rest of the body.
