* Oocyte banking. Hormonal stimulation to ‘hyper-ovulate’ with transvaginal oocyte harvest for freezing. Previously using the "slow-freezing" cryopreservation method there were very poor survival rates of banked oocytes. However, the advent of vitrification, a rapid freezing process, has made oocyte cryopreservation a viable option for fertility preservation. It allows the possibility for eggs to later be fertilized and be placed in a surrogate, as opposed to a transgender man having to carry the pregnancy himself. | * Oocyte banking.

* Ovarian tissue banking. Ovarian tissue is frozen after oophorectomy. Even after long-term androgen therapy, ovaries usually retain usable follicles. Eventual use of frozen ovaries will require replantation into the transgender man for stimulation and harvest, but may eventually be possible in a lab as techniques for tissue culture improve. This option does not usually allow for placement into a surrogate as it may require the use of immunosuppressants on the part of the surrogate. | * Ovarian tissue banking.
