Hi
I don't believe symptoms or ring tests or the shape of my belly can tell a boy or girl.
I do believe "old fashion" science lol

Now male sperm is faster but dies off faster
Female sperm is slower but lasts longer

I have two girls.

My first was natural and not timed or anything.
My second was ovulation induction
And we had timed intercourse so I figured the male sperm died off before the egg came down?

This time I had IUI so I was wondering if there was more girls than boys made with IUI? Or if the boy sperm had more of a chance because it was inserted closer to the egg?

Of course I may be kidding myself there is any pattern and I will have to just wait and see lol
