Surrogacy is just another job. There is no inherent reason, beyond moralistic ones, that women should not be able to sell use of their body for pregnancy.
Studies have found most women who enter into surrogacy are completely happy with their decision which they have thoroughly thought through. There is no evidence of pressure and they were usually already mothers.
The surrogates in these studies are white, married, Christian," and not especially poor. While they are glad to have the money, they are surrogates for other reasons. Many report that they enjoy being pregnant. They are proud of their accomplishment, and glad that they could make such a difference in the lives of otherwise childless couples.” Studies “conclud[ed] that money was rarely the sole and infrequently even the primary reason for entering the arrangement.”
To avoid exploitation, legal parameters can be introduced, such as ensuring prospective surrogates are financially stable and only allowing surrogates who have previously had children so that they are aware of the gravity of the process.
Commodification of the body, including surrogacy, need not be an emotionally traumatic experience. Research into sex work shows the Self must be split from the body to make it possible to “sell your body without selling yourself.” The body becomes sex. Sex becomes a service. The story of the sex worker says: the Split Self is not only possible, it is the ideal.
