“Love” Hormone, Reason Behind Obsessive Sex Drive

Believe it or not but an unregulated supply of “love” hormone from the brain may be the reason behind obsessive sex thoughts and a compulsion to perform sexual acts in some people characterized as hypersexuals.

A new study on men and women with hypersexual disorder has revealed a possible role of the hormone oxytocin, also known as “cuddle” or “love” hormone, according to researchers.

Hypersexual disorder, or an overactive sex drive, is recognized as a compulsive sexual behaviour disorder, listed as an impulse-control disorder by the World Health Organisation (WHO).

While prevalence estimates vary, literature indicates that hypersexual disorder affects 3-6 per cent of population globally.

“We set out to investigate the epigenetic regulatory mechanisms behind hypersexual disorder so we could determine whether it has any hallmarks that make it distinct from other health issues,” said lead author Adrian Bostrom from Uppsala University, Sweden.

“Our study is the first to implicate dysregulated epigenetic mechanisms of both DNA methylation and microRNA activity and the involvement of oxytocin in the brain among patients seeking treatment for hypersexuality,” added Bostrom who conducted the study with researchers from the Andrology/Sexual Medicine Group (ANOVA) at Karolinska Institutet, Stockholm.

The team investigated 8,852 regions of DNA methylation associated to nearby microRNAs to identify any variations between samples.

They also compared their findings to samples from 107 subjects, 24 of whom were alcohol-dependent, to explore an association with addictive behaviour.

Results identified two regions of DNA that were altered in hypersexual disorder patients.

Analysis revealed that the microRNA targets genes that are normally expressed at particularly high levels in the brain and that are involved in the regulation of the hormone oxytocin.

Previous studies have demonstrated that oxytocin is associated with the regulation of social and pair-bonding, sexual reproduction and aggressive behaviour in both men and women.

The comparison with alcohol-dependent subjects revealed the same DNA region to be significantly under-methylated, suggesting that it may be primarily associated with the addictive components of hypersexual disorder, such as sex addiction, dysregulated sexual desire, compulsivity and impulsivity, said the study published in the journal Epigenetics.

The finding could potentially open the door to treating the disorder by engineering a way to suppress its activity.

“Further research will be needed to investigate the role of microRNA and oxytocin in hypersexual disorder, but our results suggest it could be worthwhile to examine the benefits of drug and psychotherapy to reduce the activity of oxytocin,” said Professor Jussi Jokinen from Umea University, Sweden.

Views About Uncommitted Sex Can Put Your Marriage at Risk

Moreover, people who had relatively unrestricted partners experienced more rapid declines in satisfaction over the first several years of marriage, which ultimately predicted dissolution

The Ministry of Women and Child Development (WCD) on Tuesday said it has decided to issue another Look-out Circular (LoC) in a NRI matrimonial dispute.

An individual’s premarital views about uncommitted sex, such as one-night stands or casual sex, may make it more difficult to remain blissfully married, suggests a new study.

Published in the journal Psychological Science, the research outlines several factors that can contribute to a marriage’s long-term happiness or dissolution, including one big red flag: An individual’s behaviour and attitude about uncommitted sexual relationships even before the marriage.

“Marital satisfaction generally declines over time, but what we’ve found is that when, prior to their marriage, one or both spouses hold generalised beliefs that uncommitted sex is OK, that can contribute to the failure of a marriage,” said the study’s first author Juliana French from Florida State University.

For the study, the research team collected and analysed data from 204 heterosexual, newly married couples.

They collected information on their behaviours and attitudes prior to the marriage as well as numerous factors related to their new marriages including marital satisfaction.

Over the course of several years, researchers followed up with couples to collect information about their marital satisfaction and cataloged data on which couples separated or filed for divorce.

For the study, the research team collected and analysed data from 204 heterosexual, newly married couples.

In this study, the researchers focused on the degree to which people expressed “unrestricted sociosexual” behaviours, desires and attitudes prior to marriage, which indicated that they were more likely to engage in uncommitted sexual relationships such as one-night stands and generally believed that sex without love is okay.

Of the couples involved in the study, people who were relatively unrestricted were less satisfied at the start of their marriages.

Moreover, people who had relatively unrestricted partners experienced more rapid declines in satisfaction over the first several years of marriage, which ultimately predicted dissolution.

“What we found most surprising about these results was the fact that both couple members’ sociosexuality play an important role in long-term, marital outcomes,” French said.

“We found evidence suggesting that couples who maintain a consistent, satisfying sexual relationship or couples who maintain low levels of stress are buffered against these negative outcomes,” French added. (IANS)
