Via Eric Barker, we learn this:
Donor recruitment at the egg agencies and sperm banks appeared to reinforce these stereotypes, Almeling found. Egg agency advertisements tend to appeal to women’s altruism, while men are informed of a job opportunity. The application process for donors also favors what Almeling called “gendered stereotypes of selfless motherhood and distant fatherhood.” Although egg donors stood to be handsomely compensated, women who indicated there was a financial motive behind their participation were routinely rejected in favor of applicants who expressed more altruistic motives, such as the desire to “help” infertile couples. Sperm banks, meanwhile, were much less explicit about the need to appear altruistic.
The entire post is interesting.
