Conclusions
It should be noted that citing problems with epidemiologic studies is not the same as disproving their claims. However, it does cast doubt upon the validity and general applicability of their conclusions. The Rossing study strongly suggests an association between ovarian tumors and long-term use of clomiphene citrate. At the same time, it can safely be said that evidence that clomiphene or hMG therapy predisposes the patient to the development of ovarian epithelial carcinoma or any other ovarian tumor is extremely tenuous. Furthermore, there is no consistent physiologic principle (such as “incessant ovulation”) which can be applied to the use of these ovulation-inducing medications to suggest that they would be likely to cause such tumors.
Therefore, physicians administering ovulation-inducing medications and contemplating the ramifications of a possible link between ovarian cancer and fertility medications are left with medicolegal considerations and with the simple principles of prudence and the dictum first to do no harm. As always, patients should be informed and offered alternatives. However, modification of the current practice of ovulation induction or ovarian superovulation on the basis of these epidemiologic studies does not seem warranted.
