What judgments does Iago pass on women in his conversation with Desdemona and Emilia? What is the purpose of his statements?

In Othello Act II, Iago uses verbal
irony to reveal his misogynistic attitude toward
women:

Come on, come on; you are pictures out
of doors,
Bells in your parlors, wild-cats in your
kitchens,
Saints m your injuries, devils being
offended,
Players in your housewifery, and housewives' in
your
beds.

AND

You rise to play and go to bed to
work.

It is clear
that Iago relishes his male reputation, as it affords him the voice to make such damning
statements about women in front of women.  They cannot retaliate, only laugh it
off.

The Elizabethan culture was overtly sexist, full of
double standards.  Men could talk; women were to remain quiet.  Men were educated; women
were not.  Men could have affairs; women were to remain virgins.  So, Iago is saying
that women are deceivers: they only toy with men, pretending to be domestic housewives
("rise to play"), but really all they want it sex ("go to bed to
work").

In this way, Iago characterizes these otherwise
pure women as common prostitutes, even in marriage.  The irony, of course, is that Iago
is the deceiver who will have these two women murdered in a bed by the play's
end.
