Women - Sell your eggs! - If you are accepted as an egg donor, you can expect to earn $2,500 to $10,000 for each round of donations. This might sound like easy money but it isn't. The screening process alone can take a month or so and you have a 90% chance of being weeded out. Your body will also go through a bit of physical trauma too so this isn't all fun and games.

In most cases you need to have a college degree and be under about 35 years old (the age limit varies, some go as low as 28). If you have a dubious family history re: health then that will take you out of the running too. They are looking for super-women really, people who are medically sound and mentally fit. If you are fat, ugly, stupid, diseased, a smoker, or if your family has a poor health history then you can expect to be rejected.

If you are accepted, you can expect six to eight weeks of agony. They pump you full of hormones and you have to make frequent visits to the donation center for blood tests and ultra-sound checks. You can expect to be bloated, gain weight, and suffer some abdominal pain before it is all over. There is also the possiblility of more severe complications but those are rare - the donation center will fill you in on all of that.

Here is a good video to get you started. How to Become an Egg Donor.

Men - Sell your sperm! - If you have 15 minutes and a strong elbow, you could make thousands of dollars a year donating sperm. Getting paid to pleasure yourself may sound like a good job, and I guess it probably is, but before you can cash in you'll have to go through a rigorous screening process. If you get accepted, and 95% of applicants are not, then you can expect to earn about $1000 a month. Not bad.

To qualify, you usually need to between 18 and 35 years old. Before you are accepted you'll have to provide a free sample (lol) so they can see how strong your swimmers are. They will freeze them and thaw them out to see how well they survive so cross your fingers. You'll also have to submit to a battery of questionnaires regarding your family's health so be prepared for that. If you are fat, ugly, crazy, diseased, or anything like that your chances of being accepted are poor.
