Is the human an exception to the evolutionarily-conserved phenomenon of pre-fertilization zona pellucida resistance to proteolysis induced by oviductal fluid? Context: Is zona pellucida (ZP) resistance to proteolysis, induced by oviductal fluid (OF), a mechanism common to species other than the pig and cow?
assistant
ZP resistance to proteolysis induced by OF was observed in the mouse, rat, hamster, rabbit, sheep, goat, pig and cow, but not in humans. Final Decision: yes
