Reports indicate that a research team at the University of British Columbia in Vancouver found through experiments on mice that the levels of the female hormone "estradiol" in female mice increase hundreds of times during pregnancy, accelerating the regeneration of neurons in the "hippocampus," which is primarily responsible for memory and spatial awareness.
The report points out that during hormone therapy for menopause, doctors generally use another hormone, "estrone." Researchers found that using estrone on female mice that had been pregnant would impair their memory and learning abilities.
In contrast, using estrone on female mice that had never been pregnant produced the opposite effect. This suggests that the estradiol produced during pregnancy significantly alters the brain structure of females.
The researchers from the university stated that in the future, when treating women with brain degeneration, it may be necessary to consider whether they have been pregnant before.
