A study reveals why you feel attracted to the opposite gender

In an advance that can be helpful in the treatment of patients with psycho-sexual disorders, researchers have found that a brain hormone called kisspeptin is responsible for attraction towards the opposite sex as well as sexual behaviours. Kisspeptin has already been determined as the fundamental molecule within the brain responsible for triggering puberty and controlling fertility.

The new findings show that puberty, fertility, attraction and sex are all controlled by a single molecule – kisspeptin – but through different brain circuits running in parallel with one another.

The study was conducted on mice and revealed that a subset of neurons in the hypothalamus — a brain region — drives both attraction to the opposite sex and sexual behaviour.

It was found that pheromones — a chemical substance produced and released by an animal was secreted by the male mouse which activated these neurons which, in turn, transmitted this signal to another population of neurons (gonadotropin-releasing hormone neurons) to drive attraction to the opposite sex.

Simultaneously, they also transmit this signal to cells that produce the neurotransmitter nitric oxide to trigger sexual behaviour, the researchers said.

“This work has provided new insight into how the brain decodes signals from the outside world and then translates these environmental cues into behaviour,” said Ulrich Boehm, Professor at the Saarland University in Germany.

This research opens up new and exciting possibilities for the treatment of patients with psycho-sexual disorders such as hypo-sexual desire disorder, Boehm added, in a paper published in the journal Nature Communications.

“There are currently no good treatments available for women suffering from low sexual desire. The discovery that kisspeptin controls both attraction and sexual desire opens up exciting new possibilities for the development of treatments for low sexual desire,” explained Julie Bakker, Professor at Liege University in Belgium.
