RESUMO
OBJECTIVE: To report a birth of a healthy girl after long-term oocyte cryopreservation by slow cooling in sodium depleted medium. DESIGN: Clinical application. SETTING: University Affiliated, Private IVF center. PATIENT: A 38-year-old woman received embryos from IVF by intracytoplasmic sperm injection (ICSI) with her own oocytes that were cryopreserved by slow freezing in a low-sodium medium 14 years and 6 months before, when she was 24 years old. MAIN OUTCOME MEASURE(S): Survival, fertilization, cleavage, clinical pregnancy and delivery. RESULT(S): From six metaphase-II oocytes thawed, two survived, one was fertilized after ICSI and a cleaving embryo was transferred on day 3. A single term pregnancy was achieved, ending with the delivery of a healthy girl. CONCLUSION(S): Cryopreservation after slow freezing in a sodium depleted medium maintained the developmental competence of oocytes after long-term storage and resulted in a successful live birth. As far as is known, this case represents, up to date, the longest storage period of cryopreserved human oocytes resulting in a live birth.

A woman aged 38 was referred to this center for surrogacy treatment, after subtotal ablation of her uterus due to a severe postpartum hemorrhage. Her hormonal profiles and ovarian structure were normal. The husband proved fertile and semen analysis was normal. The carrier, a woman 39 years old, fertile with two children of her own, and a long bonding friendship with the patient. After hormonal stimulation with gonadotropins and GnRH antagonist, six mature oocytes were obtained. These originated four embryos after in vitro fertilization, three of which were transferred to the carrier, achieving a singleton pregnancy which led to the birth of a normal child, now more than a year old. A lawsuit was filed after birth requesting the baby be registered with the biological parents name. The judge granted the request based on evidence and testimonies provided, international jurisprudence history and specification in Article 19 of the Argentine Constitution: "No inhabitant of the Nation shall be obliged to do what the law does not demand .nor be deprived of what it does not prohibit". This is an almost ideal example of the proceedings in a case of subrogation. However, we must always bear in mind the fact that in our country there is as yet no regulatory framework for these treatments, therefore there is a high probability of conflict.

Una mujer de 38 años de edad fue derivada a nuestro centro para un tratamiento de maternidad subrogada, por haber sufrido la ablación subtotal de su útero a causa de una hemorragia puerperal grave. Su perfil hormonal y estructura ovárica eran normales. El esposo tenía fertilidad probada y un espermograma normal. La subrogante era una mujer de 39 años, fértil, con dos hijos propios y con un largo vínculo de amistad con la paciente. Luego de una estimulación con gonadotropinas y antagonista de Gn-RH se obtuvieron 6 ovocitos maduros por punción folicular, que originaron 4 embriones por fertilización in vitro. Tres de ellos evolucionaron y fueron transferidos a la subrogante, lográndose un embarazo único que concluyó con el nacimiento de una niña normal que ya tiene dos años cumplidos. Se inició una acción solicitando la inscripción de la beba ya nacida a nombre de los padres procreacionales. El juez finalmente la otorgó basándose en las pruebas y testimonios aportados, los antecedentes en la jurisprudencia internacional, y el hecho de que según el artículo 19 de la Constitución Nacional: "Ningún habitante de la Nación será obligado a hacer lo que no manda la ley, ni privado de lo que ella no prohíbe". Este es un ejemplo casi ideal de cómo se puede desarrollar un caso de subrogación. Sin embargo, hay que tener en cuenta que en nuestro país no existe aún un marco regulatorio para estos tratamientos, por lo que no queda exenta la posibilidad de conflicto.(AU)

RESUMO
A 45-year-old woman received embryos from IVF by intracytoplasmic sperm injection (ICSI) with her own oocytes that were cryopreserved (slow freezing in a low-sodium medium) 11 years and 7 and a half months before, when she was 33 years old. From seven metaphase-II oocytes thawed, five survived, four were fertilized after ICSI and two cleaving embryos were transferred on day 3. A diamniotic dichorionic term pregnancy was achieved, ending with the delivery of two healthy girls. As far as is known, this case represents, to date, the longest storage period of cryopreserved human oocytes resulting in a live birth.
