Hypermutation in children may be linked to increased mutations in the sperm of the biological father, especially fathers who received certain forms of chemotherapy to treat cancer early in life.
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.
