Most people associate the sex hormones with puberty and reproduction. But estrogen, testosterone, and progesterone serve a much greater purpose in human health.
Numerous studies demonstrate how the sex hormones act like a master switch for every organ and tissue of the body, regulating cognitive function, mood, sleep, and all the neurotransmitters. In fact, brain health hinges completely on hormonal balance.
Neuroscientific researchers have identified thousands of receptors in various brain regions for testosterone, progesterone, and estrogen. These hormones manage the flow of the “feel good” biochemical messengers, including serotonin, dopamine, oxytocin, and endorphins. The neurotransmitters, or “happiness hormones,” signal every brain cell to perform its specific job.
As people age, hormonal imbalances can result in cognitive disorders, neurodegenerative diseases, memory loss, mental health conditions, sleep disruption, and neurotransmitter imbalances that often lead to dementia and depression.
Think of the sex hormones like a remote-control device influencing every thought, movement, behavior, action, and emotion. If the buttons don’t operate, neither will the main screen, and the hormones go haywire. This, in turn, can deteriorate brain health and lead to Alzheimer’s (AD, especially in women as their hormone levels drop when entering menopause.
According to a 2023 Columbia University Irving Medical Center study, a woman’s risk for developing AD is one in five versus one in ten for a man. The Alzheimer’s Society reports that more than 65 percent of AD patients are women over 45.
Numerous studies dating over 30 years provide scientific proof for the role of estrogen, progesterone, and testosterone replacement therapy in preventing AD and other neurodegenerative conditions. A 2024 collaboration concluded: “Multiple lines of evidence suggest that loss of estrogens in the aging brains of both women and men may play a significant role in the cognitive decline associated with AD.”
While it’s no secret that hormones protect the brain, doubt and confusion prevail among some researchers who still question the role and use of hormones in cognitive well-being. Few identify the difference between synthetic hormones and the natural bioidentical kind, similar to those produced by the body.
Unlike pellets, pharmaceutical hormone pills, patches, creams, gels, and sublinguals result in rollercoaster surges that lack the efficacy of pellets to sustain the 24-7 support that neurotransmitters require.
Further research shows that the hormone delivery method makes all the difference, with subcutaneous pellets maintaining the optimal physiological hormone levels necessary to protect the brain from AD and other diseases.
A 2025 report in the New York Times, “Sex Hormones Are Brain Hormones. What Does This Mean for Treating Brain Diseases?” states: “A growing understanding of how reproductive hormones sculpt the brain could transform the management of neurological conditions.”
Despite all the reports and evidence, why are scientists still struggling to correlate hormones and the brain?
One visionary medical team already connected the dots over 30 years ago, pioneering a safe, effective method for body and brain health. CarolAnn Tutera, president and CEO of SottoPelle®/Tutera Medical®, co-founded the company with her late husband, Dr. Gino Tutera, a medical pioneer renowned for his groundbreaking innovations using bioidentical hormone pellets.
Backed by 87 years of scientific research and slipped under the skin, subcutaneous pellets demonstrate the greatest efficacy in penetrating the blood-brain barrier for consistent hormone distribution.
The Tuteras began using pellet therapy over a decade ago to treat patients with Parkinson’s, Alzheimer’s, and other neurodegenerative symptoms, including former NFL players with concussions.
Now, CarolAnn continues this medical legacy by collaborating with neuroscientific researchers at the Amen Clinics for a new study tracking how pellet therapy may improve brain health and prevent debilitating diseases.
