Effect of the Cryopreservation Process on the CatSper Channels in Human Spermatozoa

Cryopreservation of spermatozoa is a routine procedure used in assisted reproductive technologies. However, there is limited data on its effect on the specific Ca 2+ channels involved in the key processes of capacitation and hyperactivation of the male gametes. The influence of two different cryopreservation methods upon the CatSper index (CI) of human male gametes has been investigated. After…
