Becoming a mother may be just as transformative—biologically, emotionally, and neurologically—as going through adolescence or menopause. Scientists and health experts are increasingly recognizing this experience, known as matrescence, as a profound life stage with lasting effects on a woman’s identity, hormones, and brain function.
While many women prepare thoroughly for pregnancy and childbirth, the postpartum journey remains less understood and often minimized. New findings suggest that the transition to motherhood is not simply a matter of sleep deprivation or emotional ups and downs—it is a full-body transformation that rivals other major developmental milestones.
1. What Is Matrescence?
Matrescence is a term coined by anthropologist Dana Raphael to describe the wide-ranging changes women undergo when they become mothers. Like adolescence, it marks a developmental transition—in this case, from individual identity to maternal identity.
“Matrescence is in its early stages of being studied,” said Dr. Jessica Vernon, OB-GYN and mental health director at Oula. “But we know it brings physiological and psychological changes that are not just temporary.”
The process includes changes to hormone levels, brain structure, emotions, and behavior—all in response to motherhood. Though the concept is gaining traction in academic and clinical settings, it still remains largely absent from public discourse.
2. The Hormonal Shift: More Than ‘Baby Blues’
Many new mothers experience what’s commonly known as the “baby blues” shortly after giving birth—feelings of sadness, nostalgia, and emotional turbulence. But this is only a small part of a much larger hormonal shift.
Key hormonal changes in matrescence include:
Estrogen and Progesterone: These hormones surge during pregnancy and crash after birth, creating dramatic emotional shifts—more extreme than typical PMS or even adolescence.
Oxytocin: This bonding hormone helps form emotional connections. It peaks during childbirth and increases through skin-to-skin contact and breastfeeding.
Prolactin: Essential for milk production, it also fosters maternal behaviors, such as vigilance and emotional preoccupation with the baby.
“These hormonal changes can affect cognition and emotional regulation, echoing but exceeding the hormonal turbulence of adolescence,” said Chelsey Scaffidi, author of The Mother Year.
3. Brain Rewiring: Not ‘Mommy Brain’—Real Cognitive Change
Contrary to popular belief, so-called “mommy brain” is not a sign of decline or forgetfulness. Instead, it reflects significant structural changes in the brain that support caregiving and emotional attunement.
A 2025 MRI study of 179 first-time mothers found:
4%–5% reduction in gray matter across most of the brain, especially in areas related to social understanding and emotional processing.
Some volume recovered within six months, but not fully—suggesting long-term neural remodeling.
Other brain regions, such as the amygdala, hippocampus, and prefrontal cortex, showed functional changes within weeks postpartum.
Researchers describe this as adaptive neuroplasticity—the brain’s way of reorganizing to prioritize the demands of caregiving.
“Rather than being a flaw, these changes reflect the brain becoming more efficient,” said Scaffidi. “It’s tuning out the non-essential and focusing on maternal responsiveness.”
4. Beyond Biology: An Emotional and Experiential Evolution
While biological mothers experience hormonal upheaval, adoptive mothers also undergo matrescence in emotional and behavioral terms.
Research suggests:
Adoptive mothers experience stress, identity shifts, and even post-adoption depression similar to postpartum depression.
Bonding activities like holding and nurturing a child trigger increased oxytocin, even without biological pregnancy.
Though more research is needed on adoptive maternal brain changes, their experiences point to the deeply experiential nature of matrescence.
“Motherhood isn’t defined by biology alone,” said Scaffidi. “The act of caregiving reshapes the maternal brain and identity, regardless of how a child enters the family.”
5. Why Naming ‘Matrescence’ Matters
Giving this experience a name—matrescence—can have real mental health benefits. Like adolescence, this stage is filled with contradictions: joy and grief, empowerment and loss.
“When mothers understand what they’re experiencing, they’re less likely to feel broken or alone,” Scaffidi noted.
Recognizing matrescence helps validate the emotional complexity of early motherhood. Many new mothers struggle with feeling disconnected from their previous selves. Acknowledging this transformation can promote better support, therapy, and self-compassion.
