Many modern women postpone childbearing in order to complete their education, get their career on solid footing, or find the right partner with whom they want to share their life. As a result, increasing numbers of women find themselves over age 35 and confronting fertility challenges. Improvements in oocyte cryopreservation (i.e., egg freezing) offer women the possibility of greater control of their reproductive future by potentially extending their fertility. While women with a history of premature ovarian insufficiency, ovarian cysts, living in an area with high exposure to pesticides or heavy metals, or undergoing exposure to chemical or biological warfare due to military service may also consider egg freezing, the largest numbers of women considering social egg freezing are likely to be those who either desire or foresee delaying their childbearing years._
