Welcome to HCM,
Fertisure is a vitamin supplement given empirically.
If there is no pregnancy
, you both should be tested for having any problem for not having pregnancy.
Afterwards line of treatment can be suggested.
In your case first you go for semen examination and then question of treatment comes.
There is no effect of masturbation
on semen.so forget about and go for examination of both partners.
Take high protein diet,pulses,dry fruits,green veggies etc for maintaining good quality of semen.
Ok and bye.
