3. Sell your eggs or sperm
via: livescience
A lot of people have never even considered selling their eggs or sperm, but there’s some decent money in it. The process is relatively easy for men, who can make forty dollars per donation, which is a relatively casual process. The process is harder for women, who will often have to have their eggs removed in a much more invasive way. However, women will make one thousand dollars or more in many cases for each donation, so the process is more cost-effective.
