How do childhood extracranial germ cell tumors affect pregnancy?

Whether childhood extracranial germ cell tumors affect pregnancy depends on how advanced the tumor is and what treatment is conducted. Surgery to remove cancerous ovaries in females may result in infertility; surgery to remove the entire cervix (total hysterectomy) necessarily results in inability to carry a pregnancy. Although ovarian germ cell tumors occur in egg cells, other eggs may remain unaffected and able to conceive.
