What role does the neurotransmitter serotonin play in fertility? A recent study by scientists from Nagoya University in Japan has uncovered a link between serotonin neurons, glucose availability, and reproductive health. Their findings suggest that serotonin neurons in the brain play a significant role in maintaining reproductive functions by sensing glucose levels and enhancing the release of reproductive hormones. The research was published in Scientific Reports. Depression is linked to dysfunction in central serotonergic neurons and is known to correlate with both reproductive and metabolic…
