In a nutshell Human placentas produce exceptionally high hormone levels that may have driven our brain evolution, not male competition as traditionally thought These pregnancy hormones directly ...

Liquid-chromatography-tandem mass spectrometry was used to better understand the human placental hormone pattern. The work showed that the placenta carefully calibrates how much of the hormone ...

A group of scientists studying pregnancy across six different mammals—from humans to marsupials—uncovered how certain cells ...

A new preclinical study provides the first direct evidence that loss of a placental hormone during pregnancy alters long-term brain development, causing autism-like behaviors in male offspring.

A new preclinical study provides the first direct evidence that loss of a placental hormone during pregnancy alters long-term brain development, causing autism-like behaviors in male offspring.

A recent experimental study has shown that one reason for the occurrence of autism spectrum disorder (ASD) could be the deficit of a placental steroid hormone called allopregnanolone. The reason ...

Newly reported research in mice is the first to provide direct evidence that loss of a placental hormone can alter long-term brain development in offspring. The study, headed by researchers in the ...

Unlike other primates, humans are exposed to high levels of placental sex hormones in utero, which may have shaped our evolutionary brain development By Grace Wade 20 June 2025 ...

Levels of placental hormone allopregnanolone (ALLO) were found to rise during pregnancy and peak as fetuses approach full term, revealed multi-institutional research presented during the Pediatric ...

The placenta and the hormones it produces may have played a crucial role in the evolution of the human brain, while also leading to the behavioral traits that have made human societies able to ...

Of these 164 placental samples, CYP1A1 was detected in 132 samples (80%), and levels of 2 thyroid-hormone–regulated genes tended to be higher in these pregnancies, although the mother's overall ...
