CRIOPRESERVACIÓN DE ÓVULOS
Women are born with a limited number of eggs that gradually deplete over time; additionally, egg quality can be affected by age. Furthermore, treatments such as chemotherapy and radiotherapy can significantly reduce the ovarian reserve.
La criopreservación de óvulos le da la posibilidad a las mujeres de extender su tiempo de fertilidad y así lograr la maternidad. Se recomienda realizar este procedimiento a temprana edad, pues mayor será la probabilidad de tener mejor calidad de los óvulos y mayor cantidad.
Step by step: egg freezing and future use
Ovarian stimulation:
The process begins in the first days of the menstrual cycle. Medications are administered subcutaneously to stimulate the ovaries and achieve the growth of multiple eggs.
Egg monitoring and retrieval:
Se realiza un seguimiento del crecimiento de los óvulos mediante ecografías. Cuando alcanzan el tamaño adecuado, se programa la extracción bajo sedación.
Cryopreservation and storage:
The retrieved eggs are delivered to the in vitro fertilization laboratory for cryopreservation. They can be kept frozen in the egg bank for a period of 10 to 15 years without compromising their quality.
Thawing and in vitro fertilization:
To use these eggs, they must undergo in vitro fertilization after thawing. This technology, although increasingly efficient, is not 100% effective, which is why it is recommended to freeze multiple eggs.
