Effect of dehydroleucodine (DhL) on the acrosome reaction in sperm of : signalling pathways involved.

The secondary metabolites of several plant species, particularly sesquiterpenic lactones (SLs) have been studied by different research groups for over 30 years. This group of metabolites presents numerous biological activities such as antibacterial, antiviral, antiulcer, cell proliferation inhibitor, and oocyte activator with participation in exocytosis processes. This study aims to assess some sperm parameters in epididymal gametes of exposed to increasing concentrations (0 to 2 mM) of DhL for various incubation times from 10 to 40 minutes.
