Sperm cell population dynamics in ram semen during the cryopreservation process.

ABSTRACT:

Background

Sperm cryopreservation has become an indispensable tool in biology. Initially, studies were aimed towards the development of efficient freezing protocols in different species that would allow for an efficient storage of semen samples for long periods of time, ensuring its viability. Nowadays, it is widely known that an important individual component exists in the cryoresistance of semen, and efforts are aimed at identifying those sperm characteristics that may allow us to predict this cryoresistance. This knowledge would lead, ultimately, to the design of optimized freezing protocols for the sperm characteristics of each male.

Methodology/principal findings

We have evaluated the changes that occur in the sperm head dimensions throughout the cryopreservation proces
