Can anyone recall this 60-70'ies agent half scifi, half action (with those times measured) movies ot TV series?

Here is what I remember...

It was a 60-70'ies serie of movies or TV episodes..
Its an agent kind of figure (could have been Lee Marvin). In one movie/episode he was on a island where women were in control while men were slaves and only used for reproduction or something like that . There was a lot of stuff like laboratories in the rocks and mountains and secret departments in these movies/episodes.

Anyone have any ideas?

Thanks...
