Of course there are ways to check the fertility of any female @Agbamoni but what happens if after being medically cleared to get pregnant and the lady in question doesn't get pregnant? I wouldn't blame anyone that wants evidence of how fertile a girl is by getting her pregnant before marriage, because even after running all the tests in the world there may be a spiritual thing that could prevent pregnancy from coming and many of us don't have that patience to wait around so they opt to getting their woman pregnant first before marriage. A desperate girl can go to any length to trick you into marriage and bribing their way to fake medical results isn't exceptional.
That's why premarital agreement is important, you add a clause "if the woman failed to get pregnant after 3 years of marriage, the man is allowed to breakup without share any of his asset, alimony etc". What if she avoid to accept this clause? simply she's not for you and you have a choice to find other woman.
It's just silly of the married people who fidget over such pressure, as if the relatives or friends would pay any bill pertaining to the child when birthed afterwards. Most friends like this, are losers who know nothing about bearing and raising kids. Cruel mentalities as that only get couples to go extramiles for kids, even when they're unprepared to finance the child's upbringing in this hard economy.
I wonder why people are complaining with someone else words, if they feel they can't take it anymore, better to talk straight away or counter their argument. Like their friends ask to get more baby, they can counter "I can, but you must bear and raise my kids, can you?".
