Abstract

This study explores denied pregnancy, introducing the term 'cryptic pregnancy' within an evolutionary framework. Contrary to conventional psychodynamic explanations, it emphasizes the fetus's active biological role and parent-offspring conflicts. Recent studies show a higher incidence (1:475) than believed, manifesting with atypical pregnancy symptoms and often escaping detection. The proposed term reframes the condition, prompting an exploration into physiological correlates and evolutionary implications. Cryptic pregnancy minimizes energetic and ecological costs for the mother, theorized to involve reduced human chorionic gonadotropin (hCG) production or effectiveness. Three evolutionary hypotheses are presented: as a non-adaptive outcome of conflict resolution processes linked to disruptions in genomic imprinting, resulting from spontaneous abortions of low-quality fetuses, or representing 'forced cooperation' in challenging circumstances, maximizing chances of survival until delivery. This abstract critically assesses the phenomenon, acknowledging its link to suboptimal outcomes for both mother and child. The study delves into incidence, characteristics, sub-classification, consequences, and management strategies, addressing ethical and legal considerations. Rejecting psychodynamic interpretations, it challenges traditional theories by recognizing the biological influence of the fetus and parent-offspring conflicts. The term 'cryptic pregnancy' adds depth to understanding, offering potential explanations through evolutionary perspectives. In conclusion, this research contributes to the broader discourse on denied pregnancy, shedding light on its complexity. The proposed term and evolutionary framework offer a fresh perspective, challenging existing paradigms and paving the way for further exploration. Understanding cryptic pregnancy is crucial for improved detection, management, and support for women experiencing this condition.
