Is it obligatory to inform the suitor about a history of infertility in the fiancée's family, and is the failure to inform a sin, while believing that procreation is in God's hands?

Procreation is in the hands of Allah. However, if most of the girl's female relatives do not conceive, or if this is apparent among them, the suitor must be informed so that he is aware. For the Sharia encourages marrying a "prolific" woman, whose high fertility is known by observing her relatives.
