Fetism refers to a psychological condition where an individual exhibits a fixation on fetal imagery or concepts, often manifesting in a desire to regress to a fetal state or an obsession with the idea of being in a womb-like environment. This condition can be linked to various mental health issues and may involve a longing for safety, comfort, or a return to a perceived state of innocence. Fetism is not widely recognized in clinical psychology and may be discussed more in niche or theoretical contexts.
