A recent research measured the levels of testosterone in both men and women who had recently fallen in love in the previous six months, and compared these to subjects who were either single or in a long-term relationship.

And interestingly enough, women who had just fallen in love have increased testosterone levels. It is therefore suggested that the stage of falling in love is associated with converging hormone levels. This could be a mechanism of temporally eliminating some differences between the sexes. The softening of male characteristics, like sex drive and aggression, due to testosterone, and the strengthening of the same characteristics in women may contribute to pair bonding in romantic relationships.

An increase in testosterone results in an increase in sexual behaviour in women, which is typical for the first period of love. The long-term relationship Hormonal changes are not only important in the first stage of love. There are, however, couples known who can hold the first period of love for a much longer time. In all monogamous long-term relationships, changes in hormone levels are still occurring.

Cuddles have long-term effects As shown before, oxytocin plays an important role during the initial period of romantic love. However, oxytocin also contributes to pair bonding during long-term relationships. As oxytocin makes partners more attractive and improves the interaction between couples, this hormone is beneficial to couples in long-term relationships. Moreover, it may be possible to introduce oxytocin treatments for couples with relationship issues. Temporary separation The role of cortisol in long-term relationships is mainly associated with separation of romantic partners.

In romantic partners who were in a long-term relationship, high levels of anxiety were linked to high levels of cortisol when the partners were separated. A study investigating the changes in cortisol as result of temporary physical separations, such as those caused by work-related travel, exemplifies this idea.

The researchers found significant changes in levels of cortisol from pre-separation to separation and from separation to reunion. Haselton has unveiled alterations that occur in the behavior of females during ovulation , through a sequence of trials. Also, the experts found that females whose partners are not sexually attractive and less manly are usually more likely to be attracted to other men during the most fertile days before ovulating.

The women were questioned again at two different times in their monthly cycles — right before ovulation high fertility and at low fertility points — about their satisfaction with their relationships. However, when the women were asked to rate how close they felt to their mates, the results were completely different.

The women whose partners were less sexually attractive had scores which dropped one point on seven point scale when they moved from their least fertile periods to their most fertile. On the other hand, those who mated with sexually attractive men were found to have complete opposite scores. When these women changed from their least fertile to most fertile time periods, their scores jumped by one point. The closeness of their relationships got a boost just prior to ovulation.

To confirm their conclusions, Larson and Haselton conducted the same experiment with 67 men and women involved in long-term partnerships. For the women, researchers assessed changes in estradiol, progesterone, and testosterone; for men, they only looked at testosterone.

The key findings were as follows: on days women experienced increases in estradiol a hormone that reaches its peak right around the time of ovulation , they tended to evaluate their partners more negatively.

In addition, high estradiol was linked to both men and women perceiving that their partner felt more negatively about the relationship. The researchers also found that on days estradiol was elevated, women reported less physical attraction to their partners, while men reported lower levels of sexual desire and perceived their partners as less interested in sex.

Men also reported lower psychological well-being on days their partners had higher levels of estradiol and subsequent analyses showed that changes in the way women evaluated their partners accounted for this effect.

However, the researchers did find that elevated progesterone which rises following ovulation as estradiol drops off was linked to more positive evaluations of their partner and better psychological well-being. Further, on days testosterone was higher, both men and women reported greater levels of jealously.
