Can I freeze sperm with Refrigeration Medium - TYB with Gentamicin?


No, Refrigeration Medium - TYB is intended for short term refrigerated sperm storage. Refrigeration Medium- TYB is typically used to store sperm for up to 96 hours between 2-8°C, transporting semen (e.g. home collection then transported to clinic), and as an aid in sperm capacitation for conventional fertilization.

For freezing sperm we recommend using Freezing Medium - TYB with Glycerol & Gentamicin or Arctic Sperm Cryopreservation Medium.
