Tratamientos contra el cáncer, como la quimioterapia, la radioterapia y la cirugía radical pueden inducir a la menopausia prematura y a la infertilidad en miles de mujeres en edad reproductiva. Una de las formas de preservar posiblemente la fecundidad antes de estos tratamientos es congelar tejido ovárico para su posterior transplante.
Los autores del presente trabajo criopreservaron tejido ovárico de una mujer con cáncer de mama antes de una menopausia inducida por la quimioterapia. Este tejido se transplantó bajo la piel de su abdomen seis años después. La función ovárica de la mujer se recuperó al cabo de tres meses y la fecundación in vitro resultó en el desarrollo de un embrión de cuatro células que fue implantado en la mujer, pese a que ésta no se quedó embarazada.
Los investigadores señalan que este estudio representa un significativo avance potencial en reproducción porque la mujer pudo preservar su fecundidad congelando su tejido ovárico y porque el embarazo es posible, incluso cuando el tejido ha estado congelado durante mucho tiempo.
