Research shows many men are not being told that sperm banking is an option if they want to have kids later on.
Sperm Banking is a process of collecting and freezing a man's sperm and storing it for artificial insemination sometime later on.
In a recent study, researchers found that doctors didn't inform their patients of the possibility of infertility because of lack of time for discussion, lack of convenient facilities and because they thought it might be too expensive.
