In what is certainly great news for everybody, performing oral sex is great for a woman's health and improves her mood, due to the effects of semen's 'mood-altering chemicals'.
The study — conducted by the State University of New York — was carried out through the survey of 293 women about their sex lives and mental health.
This comes after research which shows seminal fluid contains chemicals that elevates mood, increases affection, induces sleep and also contains multiple anti-depressants.
The researchers also made the claim that women who regularly have unprotected sex are less likely to be depressed and more likely to perform better on cognitive tests.
Semen contains cortisol, which is known to increase affection, as well as estrone and oxytocin, which are known to elevate mood.
It also contains a thyrotropin-releasing hormone, an antidepressant, melatonin, a sleep-inducing agent, as well as serotonin, an antidepressant neurotransmitter.
To investigate whether semen has antidepressant effects, the researchers polled 293 anonymous college females from the State University's campus at Albany.
The researched showed that the women who never used condoms were much less likely to be depressed than the women who usually or always used condoms for sexual intercourse.
The research suggests that the presence of the seminal fluid in women's bodies boosts releases endorphins and prevents depressing states, so if you're feeling depressed, ladies, find a nice guy to help relieve your stress!
