Hi I was wondering if a donor from 2002 is less viable and less able to cause pregnancy?

    Hi Meg -

    Once sperm is frozen and stored in liquid nitrogen, it is viable for an indefinite amount of time. Once thawed, there is no measurable difference in "quality" between sperm frozen one year or twenty.

    There are news reports of cryopreserved donor sperm frozen for 40 years which resulted in live births.

    In addition to our sperm donor services, we also provide private storage to young adults prior to cancer therapy who may choose to store their sperm for one or two decades until they are ready to start a family.

    Regards,

    Nicole
