I think this movie was made in the 60s or 70s, but I am not sure.
Plot:
Earth has fallen to destruction in the future, except a group of people
who
survived underground with their advanced technology intact. This group
sometimes sends explorers outside. One of their prominant doctors(?) is
lost outside and a rescue mission is sent to find him.
The rescuers (4 or 5 men and a women) find themselves captured in a
society
ruled by women where the men are kept under control by a drug that is put
in
their food. This society is attacked by "wild men", who are driven off by
the enslaved men who have been freed from the drug by these rescuers who
have found the doctor who had developed an "antidote" for the drug.
