“Impotence drugs such as Viagra may do more than help men physically have sex — they may also boost levels of a hormone linked with feelings of love,” U.S. researchers came out with a report in the recent days.

This particular hormone is not only linked with nursing and childbirth but also in orgasm as well getting immense feelings that are connected with sexual pleasures.

“Viagra, known generically as sildenafil, raised levels of the hormone oxytocin in rats,” the team at the University of Wisconsin-Madison said in a report published in the Journal of Physiology.

“And it seems Viagra and related drugs act on the part of the brain that controls release of oxytocin,” said Wisconsin physiology professor Meyer Jackson.
"This is one piece in a puzzle in which many pieces are still not available," Jackson said in a statement. "But it raises the possibility that erectile dysfunction drugs could be doing more than just affecting erectile dysfunction."
