摘要近年来，医学研究取得了长足发展，肿瘤治疗技术的发展使年轻肿瘤患者的生存率提高。但是肿瘤的化疗、放疗、内分泌或手术治疗，可导致卵巢功能低下甚至卵巢衰竭，如何有效保护和保存这些患者的生育力显得尤为重要。本文对英国生育力协会(British Fertility Society，BFS)最新发布的《医源性原因女性生育力保存的策略与实践指南》循证医学证据进行解读。

abstractsIn recent years, medical research has made great progress. Advances in oncology treatments increased survival rates in young cancer patients. However, the treatments of chemotherapy, radiotherapy, hormone therapy and surgery for oncology can result in diminished ovarian reserve and premature ovarian failure. How to effectively protect and preserve the fertility of these patients is particularly important. This article explains the evidence-based medical evidence from "Fertility preservation for medical reasons in girls and women: British fertility society policy and practice guideline".
