Semen Extraction and Analysis in Domestic Animals.

Sperm collection is a fundamental step in the subsequent application of all assisted reproduction techniques.

Furthermore, once the semen has been collected, it is necessary to carry out a simple evaluation in order to discard those samples that cannot be used.
