Recessive Genes May Quietly Shape Health, Learning, and Fertility

Carriers of recessive gene mutations, long thought to be unaffected, may actually face subtle disadvantages, including more medical issues, shorter educational attainment, and reduced reproductive success. A study of over 300,000 individuals reveals that people who carry recessive genes for intellectual disability are especially impacted, despite having only one mutated gene copy.

Serotonin Boosts Fertility

Researchers uncovered a crucial link between glucose levels, serotonin signaling, and fertility. By studying rats and goats, the team discovered that increased glucose availability stimulates serotonergic neurons, enhancing the release of reproductive hormones via the activation of kisspeptin neurons.

Link Between Parental Infertility and Autism Risk in Children

A study involving 1.3 million children found that children born to parents with fertility issues have a slightly higher risk of autism spectrum disorder (ASD). The research suggests that the risk of ASD is increased in children of parents previously diagnosed with infertility, regardless of whether fertility treatments were involved.

Stress May Be Associated With Fertility Issues in Women

Researchers say stress may directly impact female fertility and ovarian reserve. Exposing female rats to scream sounds, researchers noted a decrease in estrogen and Anti-Mullerian hormone levels. Stress also reduced the number and quality of eggs, resulting in smaller litters. The findings shed light on the role stress may play on female reproduction.
