Although prior studies have examined pregnancy outcomes for cancer survivors, clarifying the outcomes specifically for unassisted pregnancies can help guide patient and provider expectations and improve fertility preservation counseling.</div></div><div><h3>Objective</h3><div>The primary objective of this systematic review was to identify the impacts of cancer and its treatment on fertility, measured as the live birth rate among cancer survivors with an unassisted pregnancy.

Live birth rates were significantly lower in survivors of breast cancer and individuals who underwent hematopoietic stem cell transplant or abdominopelvic radiation therapy during their cancer treatment. Survivors of breast and gynecologic cancers had higher rates of pregnancy loss, although there were no differences in rates of hypertensive disorders of pregnancy, gestational diabetes, placental abnormalities, or cancer recurrence. Survivors exposed to radiation therapy were more likely to have infants who were small for gestational age or had low birth weight, and survivors of breast cancer were more likely to experience iatrogenic or spontaneous preterm birth. The effects of other types of cancers or treatments were not associated with significant differences in live birth rates or any secondary outcomes in included studies.</div></div><div><h3>Conclusion and Relevance</h3><div>Although unassisted pregnancy is possible for patients diagnosed with cancer, certain cancers and treatments are associated with decreased live birth rates and increased obstetric and neonatal complications.
