Scarlett Johansson is fascinated by men's nipples.
02/02/2009 - Scarlett Johansson - for the first six weeks of life, all embryos are proto-female. If there are no hormonal changes in the prenatal environment, the embryo developes into a female. If, however, the embryo is destined to become a male, its Y-chromosomes trigger the production of testosterone (the male hormone), which masculinizes the brain and genitalia (internal as well as external) of the embryo. But it takes no female hormone to produce a female infant. (Only at age ten or later does the female body begin to produce the hormones that transform the girl into a woman.) the end result?

The 'He's Just Not That Into You' actress can?t understand why boys still have them, adding the concept of male nipples completely baffles her.
She is quoted by the Chicago Sun Times newspaper as saying: "The one thing I don't understand about men is nipples. I don't know if there is one aspect of men that I don't understand other than why they have nipples. Honestly, why? I guess it has something to do with the X chromosome.
"What is the function of the male nipple? Maybe we all start as androgynous creatures and then they become men?"
Despite admitting she is confused by some aspects of the male anatomy, the 24-year-old actress' bewilderment is not strong enough to turn her off men completely.
She recently revealed she is still crazy for her husband Ryan Reynolds - who she married in a secret ceremony last September - adding she is "in love with love".
When asked about the impact marriage has on relationships, Scarlett replied: "I have no perspective on that - you should ask me in 25 years.
"I am really in love with love. I'm a lover not a fighter. I'm a real lover."
