Denial of Pregnancy and Its Implications

Denial of pregnancy, also known as cryptic pregnancy or unperceived pregnancy, refers to a condition in which a woman remains unaware of her gestational state for a significant portion, or the entirety, of pregnancy. This phenomenon emerges at the intersection of physiological, psychological and sociocultural factors. Physiologically, atypical hormonal responses and absence of classic gestational symptoms may obscure the perception of pregnancy. Psychologically, coping mechanisms such as repression and dissociation can attenuate bodily awareness, particularly in contexts of ambivalence, trauma or psychiatric vulnerability. Sociocultural influences, including limited prenatal education and stigma around unintended pregnancy, further compound unrecognition. Denial of pregnancy carries substantial implications for maternal and foetal well-being. Unassisted or late-presenting labour poses acute obstetric risks, while postpartum mental health and mother–infant attachment may be disrupted. Forensic and legal systems must also consider the role of concealed gestation in cases of neonaticide and obstetric violence. Understanding the multifaceted drivers and consequences of pregnancy denial is therefore vital to inform clinical screening, perinatal mental health services and policy frameworks that safeguard both mother and child.
