Can frozen sperm be stored indefinitely?

How long can frozen sperm be stored effectively? I mean, what about sperm quality? Will it be diminished if I use it after… let’s say… 5 years? I’m about to start a chemotherapy treatment and by now I’m not planning to be a father, but I’d like to in the future… That’s why I though of banking it, but I don’t know too much about it, that’s why I’m getting involved here 🙂 Is there a certain time-limit or no? Your prompt response will be highly appreciated 😉

Indeed, sperm can be frozen for an indefinite period of time. There have been pregnancies from sperm that was stored over 12 years. Nevertheless, after 12 years, sperm quality is questionable.

Apart from that, each individual sperm reacts in a different way to the freezing process, so each individual case should be determined by analyzing a thawed sperm batch.

Besides, sperm freezing or cryopreservation should be available to every patient diagnosed with cancer before starting any chemotherapy or radiotherapy treatment.
