Is it necessary to inform the suitor that his fiancée had her right ovary removed due to an ovarian cyst?

Infertility is not considered a defect that nullifies a marriage according to the majority of scholars. Therefore, the questioner is not obligated to inform the suitor about the girl's condition unless the suitor seeks his advice, in which case he should inform him, because "the one whose advice is sought is entrusted."

The suitor should verify with doctors regarding the possibility of procreation. If he ascertains that there will be no procreation, it is preferable for him to leave her, based on the hadith of Ma'qil ibn Yasar, in which the Prophet, peace and blessings be upon him, said: "Marry the affectionate, fertile woman, for I will be proud of your numbers before the nations."
