Removal of ovaries, also known as oophorectomy in women may be done for a variety of reasons. Some of the common reasons being, the presence of a tumour, infections not amenable to conservative options, cysts, endometriosis or sometimes cancer. Sometimes only one ovary is removed (unilateral oophorectomy) leaving behind the other one. A woman may become pregnant even with a single ovary in place, though conception in such a case may happen with some challenges. Further, in such cases, underlying factors like maternal age, blockage of a fallopian tube, hormonal disturbances, ovarian reserve etc may add to the existing challenges. The chances of conception after unilateral oophorectomy may range from 42-88% in case of women who may have undergone a constructive surgery for ovarian cancer or tumour removal. In case you have undergone or would be undergoing an oophorectomy and have plans to conceive later, do consult your gynaecologist about your options for increasing future chances of pregnancy like prescription medicines, egg or embryo freezing techniques
