Stress may be associated with fertility issues in women
Ovarian reserve is the reproductive potential left within a woman's two ovaries based on the number and quality of eggs. A woman is born with a finite number of eggs and her body cannot create any more. Diminished ovarian reserve is the loss of normal reproductive potential in the ovaries due to a lower count or quality of the remaining eggs.

The researchers used a scream sound model to investigate the effect of stress on ovarian reserve in female rats. They exposed female rats to a scream sound for three weeks and analyzed the effect on their sex hormones, the number and quality of their eggs and their ability to get pregnant and have babies after mating.

They found the scream sound decreased the rats' estrogen and Anti-Mullerian hormone levels. Estrogen is a group of hormones that play an important role in growth and reproductive development, and Anti-Mullerian hormone is a hormone made by the ovaries which helps form reproductive organs. The scream sound also lowered the number and quality of the women's eggs and resulted in smaller litters. Based on these findings, we suggest stress may be associated with diminished ovarian reserve.
