Ads promise thousands of dollars for females to donate their eggs, and these ads are popping up more and more on college campuses.
But is it worth the money?
Students can make money from their ailments.
$150 to join a study on athlete's foot.
$600 for research on indigestion.
But these ads, found on benches offer much more.
Up to $10,000 for young women who sell their eggs to a couple that can't have their own children.
"It's kind of a win-win situation. I'm not using them, so maybe someone else would benefit from it," said college student Alexandria Tibbitts.
Women who volunteer, could end up in a binder.
With their photo, and details about their ethnicity, height and weight, even their hobbies and grade point average.
Dr. Samual Wood runs the Reproductive Sciences Center.
His company does not advertise for egg donors, but he says it's a growing business because more older couples are trying to get pregnant, and need donor eggs.
Wood says colleges are a great place to advertise, because many female students are smarter, healthier and more attractive than the general population.
"The younger they are, the better their eggs," he said.
"I don't think I would do it, personally. To me, it's something that money can't buy. I think it's strange," said Megan Wojtysiak, a college student.
She says the idea of being paid to let a doctor harvest her eggs, makes her very uncomfortable.
She thinks the ads take advantage of college students who need money.
"I think that's exactly what they're doing," she said.
"But what I've found is that very few donors do it solely for the money. They love the idea that there's a couple that's desperate for a child and they have a chance to help them," said Wood.
Wood says a woman can make $70,000, by having her eggs harvested a maximum of seven times, over a five year period.
"And we've had egg donors pay their way through college, even pay their way through medical school," he said.
Doctor Wood says women who sell their eggs must take a series of medications for about three weeks, before her eggs are harvested. he says those medications are easy to tolerate, but some women do get abdominal pain, and decide not to do it again.
