All,
So a friend of mine is planning a family and haven’t gotten pregnant yet. Her gynac said they it may happen right away or may take even a year to conceive. Well, i don’t really understand this.
If a fertile man and woman are having frequent sex, what really leads to not getting pregnant?
In: Biology
Apart from all other issues, there are also lethal gene combinations. fA+mB might get pregnant on the firts try, and fC+mD likwise, yet fA+mD might be incompatible and never get pregnant.
