Chemotherapy treatments and other conditions such as Turner's and galactosemia can threaten the future fertility of children. At IFP, we offer innovative tissue freezing procedures to all ages of male and female children.

While mature men can preserve fertility by sperm freezing, the only option in male children is testicular tissue freezing. At IFP, we offer this experimental option for children undergoing chemotherapy.

Eggs are harvested for safekeeping in advance of cancer treatments, and reimplanted in an IVF procedure when the patient's cancer is in remission. We developed innovative strategies to keep estrogen levels low during ovarian stimulation to collect eggs so that cancer recurrence is not increased.

Oocyte freezing has come a long way. Our research shows that current success rates have approached to that of standard IVF procedures. When fertility is under threat in single women and adolescents, this is a useful strategy to preserve fertility.

This technique does not require ovarian stimulation and can be performed in children and adults with short notice. IFP's experience is unmatched, as Dr Oktay performed the first procedures in the world.
