Swiss scientists have discovered a previously unexpected function of the hunger hormone ghrelin – to increase sexual desire. Ghrelin was discovered in 1999 by Japanese researchers. They found that the amount of ghrelin in the blood increased with increasing time since eating and decreased after the first bites. The regulation of ghrelin in the body is also responsible for insatiable hunger and the desire to eat more, even though we are full. However, for the first time it is indicated as stimulating sexual desire. The effect was confirmed by an experiment in which the additional introduction of ghrelin increased the libido. NEWS_MORE_BOX Research shows that the effects of ghrelin are mediated by dopamine, which is known as the hormone of satisfaction. Low libido is a disorder of sexual function that is characterized by the lack of expression of sexual desire. Weak sexual desire can be caused by general diseases of the body and/or depression. Libido is also affected by neurotic disorders, as well as endocrine disorders. The desire for sex can also be suppressed by some drugs, congenital pathology and even by long sexual abstinence. This problem leads to disruption of normal sex life, development of negative phenomena in the organs of the small pelvis, depression and mental problems. Decreased libido occurs more often in women. In men, it is much less common and is provoked by the presence of erectile dysfunction.
