An Approach to the Factors Related to Sperm Capacitation Process

Rebeca López-Úbeda and Carmen Matás

This review summarizes some information about the different ways in relation to sperm capacitation. On one hand, the classical pathway that define the functional changes that occur in sperm during in vitro capacitation with special emphasis on the factors that lead to the tyrosine Phosphorylation (PY), and on the other hand, molecules and process that are involved in new mechanisms involved in this event like reactive species, especially Nitric Oxide (NO) and protein nitrosylation.
