Exposure to the sound of screaming linked to a decrease in the number of eggs in an experiment on female rats.
About 1 in 8 couples or about 6.7 million Americans have problems due to infertility. There are many possible causes of infertility. However, a new study suggests that stress could be a contributing factor to your infertility.
Other factors that can affect fertility in women
- A poor diet
- Excessive consumption of alcohol
- athletic training
- To be overweight
- Being underweight
- Health issues that cause hormonal changes
According to a small animal study published recently in the Journal of the Endocrine Society, Endocrinologyfemale rats exposed to screaming noise may have reduced ovarian reserve and fertility.
The remaining reproductive potential inside a woman’s two ovaries based on the quantity and quality of eggs is called ovarian reserve. A woman is born with a limited amount of eggs and her body is unable to produce more. The loss of normal reproductive potential in the ovaries as a result of a decrease in the number or quality of remaining eggs is called diminished ovarian reserve.
“We examined the effect of stress on ovarian reserve using a rat cry sound model,” said Wenyan Xi, Ph.D., of the University’s Second Affiliate Hospital. Xi’an Jiao Tong in Xian, China. “We found that female rats exposed to the sound of screaming had decreased ovarian reserve and reduced fertility.”
The researchers used a scream sound model to study the effect of stress on ovarian reserve in female rats. They exposed female rats to a scream for 3 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 that the sound of screaming reduced estrogen and anti-Mullerian hormone levels in rats. Estrogen is a group of hormones that plays a vital role in reproductive growth and development, while anti-Mullerian hormone is a hormone produced by the ovaries that helps in the formation of reproductive organs. The sound of screaming also reduced the quantity and quality of female eggs, resulting in a smaller litter.
“Based on these results, we suggest that stress may be associated with decreased ovarian reserve,” Xi said. “Determining an association between chronic stress and ovarian reserve is important, as it may expand our appreciation of the limitations of current clinical interventions and provide valuable insight into the cause of declining ovarian reserve.”
