Humans are social creatures who often form emotional bonds through physical intimacy. In particular, romantic partnerships have been shown to involve a special type of attraction that is based on sexual desire.
Attraction can be challenging for long-term couples due to changes in their hormone levels. Fortunately, there is research showing that the hormone levels of partners in long-term relationships tend to sync up over time. This phenomenon is called hormonal synchrony, and it has important implications for the couple's relationship.
One way that natural hormone cycles impact attraction is through oxytocin, also known as the "cuddle chemical". Oxytocin is a neurotransmitter that plays an essential role in the formation and maintenance of social bonds. It increases during sex, breastfeeding, and other forms of physical contact between partners. When oxytocin levels are high, individuals feel more attracted to each other and may experience greater pleasure during sexual encounters.
Another hormone involved in attraction is testosterone, which plays a key role in libido or sexual drive. Testosterone levels tend to decline with age in both men and women, which can lead to a decrease in sexual desire.
When two people spend a lot of time together, their testosterone levels may become more similar, leading to increased sexual compatibility.
Estrogen and progesterone play a role in female fertility and reproductive health. These hormones fluctuate throughout the monthly cycle, causing changes in mood and energy levels. During certain times of the cycle, women may experience heightened sensuality and sexual interest. In contrast, at other times, they may feel fatigued and uninterested in intimacy.
Couples can learn to recognize these patterns and adapt accordingly, improving communication and intimacy in their relationship.
Hormonal synchrony can have significant effects on the long-term success of romantic relationships. By understanding how hormones affect attraction, partners can work together to maintain a satisfying sexual connection over time. This requires open communication about feelings, needs, and desires and a willingness to compromise and adjust to changing circumstances.
By embracing natural hormone cycles, couples can create a more fulfilling and sustainable bond that lasts for many years.
How do natural hormone cycles synchronize in long-term couples and impact attraction?
Hormonal synchrony is defined as the phenomenon when partners' hormones are in sync with each other due to shared exposure. A longitudinal study by Frieze et al. (2017) suggests that the longer a couple has been together, the more likely they will experience hormonal synchrony.
