Gonadal failure with cyclophosphamide therapy for lupus nephritis: advances in fertility preservation

Abstract

Intravenous cyclophosphamide remains an important therapy for patients with severe systemic lupus erythematosus--including lupus nephritis, which primarily affects women in their reproductive years. As prognosis improves, the chronic toxicity of this therapy assumes greater importance. This article reviews cyclophosphamide use, its effect on gonadal function, and protection of gonadal reserve during therapy. Egg, embryo, or gonadal tissue cryopreservation and alternative therapeutic strategies are considered.
