Cryopreservation

Cryo-preservation offers a unique opportunity to freeze sperm or embryos for later use. For example, freezing of the sperm may be the only way in which a couple can have assisted conception if the male partner is away at the critical time. The frozen sperm specimen is thawed and used as required.
As regards embryo freezing, good embryos frequently remain after the initial fresh embryo transfer. The embryo not immediately transferred can be frozen and used at a later date without the need for fresh stimulation of the ovaries and its associated costs.
