Infertility and childlessness stigmas
Infertility and childlessness stigmas are social and cultural codes that identify the inability to have children as a disgraceful state of being. Broadly speaking, in many cultures, "Demonstrating fertility is necessary to be considered a full adult, a real man or woman, and to leave a legacy after death," and thus the failure to make this demonstration is penalized.
