Semen acts as an anti-depressant

NewScientist:

Semen makes you happy. That's the remarkable conclusion of a study comparing women whose partners wear condoms with those whose partners don't.

The study, which is bound to provoke controversy, showed that the women who were directly exposed to semen were less depressed. The researchers think this is because mood-altering hormones in semen are absorbed through the vagina. They say they have ruled out other explanations.
