Abstract: With the universal two-child policy in China, a considerable part of the rebirth patients are coming into the age of ovarian reserve function decline (DOR) at present. DOR indicates the decreasing reaction to ovarian stimulation, the decreasing quality of oocyte, and the status of "hard to pregnancy and easy to abortion". It is very important to assess accurately and promptly the ovarian reserve of DOR rebirth patients. At present, the treatment strategy for DOR patients includes: ①Assisted reproductive technology(ART) is recommended actively, in which the mild stimulation, minimal stimulation or natural cycles is the increasing popular ART strategy in DOR patients; ②Growth hormones, weak androgens and antioxidants can be added to improve the clinical outcomes of in vitro fertilization (IVF); ③The clinical outcomes could be still unsatisfied for those aged DOR patients even if the donated egg IVF combined with reproductive engineering technology was used.
