Hospitals may be seeing a lot of action in delivery rooms come November 2015 due to last month's premiere of "Fifty Shades of Grey" - the movie adaptation of E.L. James' erotic novel.

November is precisely nine months after the release of the film, and hospital staffs are already preparing employees for the predicted spike in births, or "baby boom."

"Fifty Shades," one of the most highly anticipated movies of the year, raked in upwards of $500 million in the first couple of weeks that it hit the big screen. It's not often that a sex-based, sadomasochistic-type film makes it to the theater, so many felt that they had to take advantage of the opportunity.

However, some viewers may have had a hard time just watching the film. Because of the graphic and stimulating content, the movie just may have excited audiences enough to cause them to act on their "fantasies" . . . hence, the baby boom.

One hospital in England has reportedly urged its employees in the maternity ward to book their vacations now, if they wish to have their time off approved, according to The Daily Mail.

It posted a note that read: "Important information for midwives. The movie 'Fifty Shades of Grey' is being released February 13, 2015 + 40 weeks = November 20, 2015. Book your annual leave now."

The note was allegedly put up at St. James' University Hospital a day before the film's Feb. 13 release, but a hospital spokesman couldn't provide any evidence to support the incident.

"Fifty Shades" - starring Dakota Johnson and Jamie Dornan - tells the story of a sadomasochistic billionaire named Christian Grey who has a love affair with Anastasia Steele, and their romance allows the once-innocent Anastasia to explore her darker desires.

This isn't the first time "Fifty Shades" was predicted to bring on a baby boom. In the summer of 2012, the book's popularity was at its peak, and many claimed a new baby boom would occur, but according to official data, births the following year decreased by 4 percent.

"Fifty Shades of Grey" will be released on DVD on June 22 in the U.S.
