Is passing a struct value to a method by-reference in C# an acceptable optimization?

Say I have a struct:

struct MyStruct
{
    public int X
    public int Y
}

And a method in some class that is iterated over many times elsewhere:

public bool MyMethod( MyStruct myStruct )
{
    return ...
}

Is changing the MyMethod signature to the following an acceptable optimization?

public bool MyMethod( ref MyStruct myStruct )

If so, how much of an advantage would it really be? If not, about how many fields would a struct need for a big enough advantage using ref this way?
