E.g You have a problem which might mean you are unable to have children, you might be able to have children but at this stage you do not know.
I understand the need for honesty and I fully advocate it (forexample like mirch mentioned, hiding girl's serious psychiatric problems before nikah, or another example not disclosing a speech disability of the boy before rishta.... in those cases honesty was the best policy)
but isn't info about fertility waaaaaaaaay tooooooooooo personal.???.. any adult/human has a right to keep such personal medical info Private and is under no obligation to disclose it to anyone ...
or is there an obligation? i seriously don't know where u should draw the line...
should info about fertility problems be considered same as the info about psychiatric or speach or sight problems?
the situation u pose is different though... in your situation the person is not even 100% sure that they will have problems (as u said in your post they only think they might or they might not) then i don't think it is right to convey/spread such a "doubt' to the potential rishtaa walay laug... because u dont know for sure yourself... its not like you are hiding something u knew for sure...
and even if some one knows that they might have problems conceiving, that doesnt mean that they will end up with no children, there are medical options available such as IVF, IUI etc that can be discussed later on privatley by husband and wife with the doctors , and there will be no need to involve the whole khaandan then...
i advocate honesty in rishtaas
but unfortunately when it comes to fertility info (and specially when this info is NOT even 100% for sure, written in stone, medically indisputable type ) then i agree with shark man and sara... just marry be happy if u are meant to have kids u will ...
its not like the person in your situation/scenario is specifically being asked for this type of personal info by the inlaws, and its not like the inlaws are taking him/her zabardasti to the doctor to get fertility tests done, so that he/she has to disclose that info... they cannot make him/her do that due to privacy laws...
they find out later you already knew, they'll thing you've decieved them.
What does one do in such a situation...?
and how will they find out that you already knew this info before ???
