Our hospital calculated the number of frozen oocytes required to give birth to one child from statistics for each age. The birth rate (%) for each number of thawed oocytes is as follows.
|10 oocytes||20 oocytes||30 oocytes||40 oocytes|
This table is based on Cil AP, Bang H, Oktay K. Age-specific probability of live birth with oocyte cryopreservation: an individual patient data meta-analysis. Fertil Steril. 2013; 100 (2): 492-499. This research originates with the Oak Clinic Group.
Many patients try to freeze as many oocytes as possible, hopefully this guide can help to build confidence.
