A new book called The Decline Of Men claims that the rise of sexual equality has led to men becoming the weaker sex.
And it's not only social factors such as equal pay that are making men feel emasculated. Scientists have also found that pollution is damaging men's ability to reproduce.
Do you think that women have now overtaken men as the dominant sex? Has feminism succeeded in its mission?
Are women much better off than they were in the past, or are you still struggling to get the same recognition as your male counterparts?
Do you have any sympathy for men, or do you think it's time they suffered a little too after millions of years as the dominant sex?
