Stress can cause disorders associated with the development of the main sex hormone, and ultimately lead to problems of the reproductive system, scientists believe.

Experts explain this by the fact that excessive psychological stress promotes an increase in the level of stress hormones in the body - glucocorticoids. In turn, hormones such as cortisol interfere with the production of the main sex hormone - gonadotropin (GnRH) and suppress sperm function, the process of ovulation and sexual activity, doctors explain.

A new study found that stress also increases the level of the reproductive hormone called the hormone inhibitor gonadotropin (GnIH). It was found that a small protein of this hormone RFRP inhibits the immediate reproduction of gonadotropin, thereby contributing to infertility.

The findings of physicians are based on experiments on laboratory rats and the observed effects of hormone work in the body of birds.

The results indicated that GnIH plays a large role in maintaining the reproductive functions of mammals, and hence the human body, too. Thus, clinicians say, chronic stress in men and women leads to a decrease in sexual desire and a general decrease in fertility due to a reduction in the probability of successful fertilization. Stress affects many molecular processes in the brain, responsible for the production of hormones that interfere with the normal functioning of reproductive function, the researchers concluded..
