The results of laboratory tests show that the hormone kisspeptin helps stimulate the desire for sexual activity in the brains of men and women who lacked that desire.
Brain scans of participants in studies related to this hormone while they were watching sex videos showed that this hormone was able to stimulate important areas involved in sexual desire in their brains.
British researchers claim that kisspeptin has the ability to treat the condition of men and women who lack the desire for social action, a problem that affects 10 percent of the population.
Researchers from the University of Imperial College London say that young people are more likely to feel a problem when their desire for sex increases, unlike older people (who do not see a decrease in their desire as a problem that needs treatment).
Researchers say that there are those who do not care about this problem, but when this issue causes you anxiety, it can cause damage that can affect you psychologically and cause social effects.
Peter, not his real name, aged 43, had a lifelong problem with low sexual desire when he volunteered to take part in trials of this hormone.
"I always find a reason not to have sex, for example I say I'm too tired or stressed," says Peter.
"But I couldn't tell the other person I was in a relationship with because I didn't want them to betray my lack of willpower and lack of attraction," he added.
'Displeasure'
Kisspeptin is a natural hormone that stimulates the release of other reproductive hormones in the body. It plays an important role in puberty.
Previous research has shown that it can stimulate women's ovaries to produce eggs, while improving the health of men.
It is the first time that this hormone has been tested for people suffering from lack of sexual desire, a problem that has affected their lives.
"Men and women with a low level of sexual desire say they find themselves thinking too much and are confused when they fail to perform the act of intercourse properly," says the co-author of this study, Dr. Alexander Komnenos of Imperial College.
"Kisspeptin restores a natural balance, which reduces a person's sense of self-blame regarding their ability to desire sex," says Komnenos.
This hormone works differently from the male enhancement drug Viagra, which treats erectile dysfunction by increasing the flow of sperm into the penis.
The studies, which involved 32 men, heterosexual men (aged 21 to 52) and heterosexual women aged 19 to 48, are the first to test the hormone kisspeptin. people with sexual problems.
Participants were first given a drop of the hormone kisspeptin, then given several drops and told that it was kisspeptin.
Their emotions, movements and brain activity while watching sex videos were evaluated using an MRI brain scan.
Their penile erection was also measured at the same time.
Peter says that the experience of being scanned while they were having sex was "weird".
He enjoys sharing. He says, "I am now a father. Within a week of receiving the dose, I was able to have normal sex, which after several months resulted in the birth of a child."
No one can confirm that this pregnancy was related to whether or not Peter received hormones, but he says he feels "more interested in sex now".
The hormone kisspeptin has been found to improve the activity of key areas of the brain associated with sexual desire in both men and women.
Those who suffered more from lack of appetite have shown more improvement in their conditions in it.
Research reports that erectile dysfunction increased by 56% when men were given the hormone kisspeptin compared to a placebo.
"Many of them saw a positive effect in the MRI scan, which is usually not a good environment that can stimulate the desire for sex, so the effect was greater when they were in the beds of their rooms," Dr. Komnenos said.
Overall, women said they felt "more sexually aroused" when they used kisspeptin, while men reported increased "sexual pleasure".
The British Ministry of Health website says that low sexual desire is a common problem caused by various factors including relationship problems, stress, low hormone levels during menopause and postpartum depression. erectile dysfunction or vaginal dryness.
Taking certain types of medication, such as antidepressants, or using certain birth control methods can affect libido.
Other causes include excessive alcohol use, chronic diseases such as heart disease, diabetes, and cancer.
