Medium for freezing human sperm cells

SpermFreeze is a single step freezing medium for use with human sperm cells. The medium is clear (does not contain milk, egg yolk, …) and can be used direct from the bottle.

SpermFreeze requires 0.7mL of medium for each millilitre of semen.

We also offer a more concentrated SpermFreeze which allows 3mL of semen to be cryopreserved with 1mL of SpermFreeze SSP.
