The number one reason why most candidates who apply to be a contestant on The Bachelor are rejected has no connection with their looks.

Here's Why Most People Don't Make The Cut

On Tuesday, Feb. 27, the New York Post published an excerpt from Amy Kaufman's upcoming book, Bachelor Nation: Inside the World of America's Favorite Guilty Pleasure, which revealed that the main reason why applicants do not get accepted on the show is an STD.

"As soon as the medical tests came back, you'd see that herpes was the biggest thing," said Ben Hatta, who formerly served as an assistant to the ABC dating / relationship reality series' creator, producer and writer, Mike Fleiss.

"And sometimes you'd be the first person to tell a contestant that they had herpes. You'd be like, 'Uh, you should call your doctor.' Why? 'We're not going to be able to have you on our show, but you should call your doctor,'" he continued.

The Bachelor and its female counterpart, The Bachelorette, are incredibly popular shows and dozens of potential candidates apply to be on the ABC series every season.

During the audition process, the applicants are required to undergo a medical checkup, during which it is revealed whether they are carrying a sexually transmitted disease.

However, this seems logical given the fact that more than one in six Americans in the 14-49 age group have genital herpes and some of the contestants do end up having (implied) sex with their season's bachelor or bachelorette.

Applicants Go Through Several Rounds Of Scrutiny

Each and every contestant who applies to appear on the reality show has to successfully pass through several rounds of intense scrutiny in order to make the cut. These include a 150-question personality test, a personal interview round, a therapy session as well as an interview with a panel that comprises of 24 producers.

Moreover, the applicants' mental state is also evaluated before they're selected for the show, which is hosted by Chris Harrison. The candidates have to give a psychological test, which allows the producers to single out the wackos from the group.

In her book, Kaufman also pointed out that once contestants are chosen to be on the show, as many as a dozen of them are accommodated in a single room with bunk beds and are kept isolated from the outside world.
