I am fron India and in India there is a belief that right side ovary conception = boys. They think the those eggs attract boy sperms (polarity) ! Infact very early in pregnancy, they ask a woman if she feels any knot/stretch/any activity on the left or right & that denotes the sex...Only Doctors can confirm the truth in this !
My sister ovulated from left & had 2 girls, I ovulated from left and have 1 girl.
