The Claim
In pregnant C57BL/6NCrl mice, the thermoregulatory system suppresses peripheral thermogenesis and redirects endocrine signaling by overriding central thyroid hormone effects to maintain maternal–fetal energy balance.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In pregnant C57BL/6NCrl mice, changes in thyroid hormone signaling reduce heat production in peripheral tissues and alter endocrine pathways to preserve energy for fetal development.
See the scientific wording
In pregnant C57BL/6NCrl mice, the thermoregulatory system prioritizes fetal protection by overriding central thyroid hormone effects, suppressing peripheral thermogenesis, and redirecting endocrine signaling—demonstrating a hierarchical adaptation to maintain maternal–fetal energy balance.
During pregnancy, the body stops using fat stores to generate heat even when thyroid hormone levels rise, instead shifting energy use to the liver to release fuel for the fetus. The brain lowers the body's temperature setting, fat tissues stop making heat, and the liver produces a hormone that increases sugar availability without producing extra heat.
What the research says
1 studyStudy: Pregnancy negates thyroid hormone-induced pyrexia.
When pregnant mice get extra thyroid hormone, their bodies normally would get hotter, but instead, they block that heat response to keep the babies safe. They stop burning fat for heat and use a different hormone to keep mom energized instead.
