The last half century has seen incredible advances in reproductive science that have the potential to change the quality of life for everyone.

Let’s start with the variants of ovarian cortex transplantation, where the approximately 1-2 mm thick layer of cortex from an ovary is harvested and then stored at negative three-digit Celsius temperatures. For this example, I would like to draw your attention to a pair of identical 37-year-old twins; a twin had been diagnosed with “Turner syndrome who suffered from premature ovarian failure (OPF) at the age of 15”. At the time of the operation, the other twin had given birth to 2 children. Doctors were able to transplant an ovarian cortex from one twin to the other, allowing the POF twin to successfully give birth to her own child in 2011.

Flash forward to 2019, where a 36-year-old twin brother passed a ball to his identical twin born without testicles, and for symmetry in this post, the new Uni-ball then passes to the father of a child. The procedure was rather intense and urgent, but the important thing here is that the proof of concept works for both genders.

Both procedures had a high predicted success rate because both procedures involved identical twins, so organ rejection was minimized; and since no one is more identical than themselves, all of these advances in reproductive science open the door to a whole new set of options for all of us.

Medical advances have come so far that it is possible to remove an ovarian cortex/testicle and freeze it for a later date, such as after completing soft tissue-ravaging chemotherapy. A reversal of menopausal syndromes has been recorded after female patients have had successful re-transplantation of the ovarian cortex, so a similar type of result should also be true for men.
