The Oncofertility Consortium® works with clinical experts to investigate the efficacy and safety of fertility preservation techniques and pregnancy after cancer. 

Preserving reproductive options BEFORE and DURING cancer treatments

Many current fertility preservation techniques require controlled ovarian stimulation (COS) prior to oocyte or embryo banking. Important information about COS includes:

Fertility preservation options are also available that do not require hormonal stimulation:

Reproductive options AFTER cancer


Pregnancy Rates After Cancer
Several factors need to be accounted for when predicting the change of future pregnancy when banking embryos or eggs. First of all, one must consider the anticipated 'success' of a controlled ovarian stimulation (COS) procedure, in terms of stimulation characteristics, oocyte yield, fertilization rates, etc. Next, it is important to predict actual pregnancy rates from cryopreserved oocytes or embryos per transfer cycle.
