New study: Male sexual desire peaks around the age of forty, while female desire peaks significantly earlier.

Sexual desire differs significantly between men and women throughout their lives. While it increases in men from young adulthood and peaks around the age of forty, in women it is strongest between the ages of twenty and thirty. A new study by Estonian scientists also shows that even during the period of highest sexual appetite, women have a lower level of sexual desire than men for most of their adult lives.

A research team from the University of Tartu analyzed data from more than 67,000 adults aged 20 to 84 years. The results showed that male sexual desire increases around the age of twenty, peaks at the beginning of the forties, and then begins to gradually decline. However, the development was different for women. Female sexual appetite was highest in early adulthood, approximately between the ages of 20 and 30, after which it gradually decreased, and after the age of fifty, there was a significant drop.

“The analysis also showed that even the highest level of female sexual desire at ages 20 to 30 was lower than the average level of sexual desire in men for most of their adult lives. Only after the age of sixty does male sexual desire drop below the highest values ever achieved by women,” comments the study results Lucie Slováčková, an expert on healthy sexuality from Růžový slon.

According to scientists, it was already known that men generally report higher sexual desire than women; however, new data shows how pronounced these differences are across different age periods. “It is particularly remarkable how significantly higher male sexual desire was compared to women for most of adult life,” stated Toivo Aavik, a professor at the University of Tartu and co-author of the study published in the scientific journal Scientific Reports. “Desire is not a marginal issue. It is key to how people experience sex, establish sexual relationships, and evaluate their intimate lives. Practically speaking, it is also extremely important for the health of relationships – and of course for overall health,” added Aavik.

The findings are surprising to experts also because they contradict the assumption that sexual desire is closely tied to biological factors and fertility. Testosterone levels in men begin to decline as early as the beginning of their thirties. Despite this, a study suggests that libido in men continues to rise for about another ten years. According to experts, social, psychological, and relational factors also play a significant role. “Men at forty are more often in stable long-term relationships, which are associated with higher levels of sexual activity and emotional closeness,” described Lucie Slováčková.

Different libido across professions and relationship statuses

The study also found that certain professions were associated with higher sexual appetites. These include positions in machine operation, top management, drivers, and the military. On the other hand, office workers and those in customer service reported lower sexual appetites.

Relationship status also had a different impact depending on gender. “Men in partnerships reported higher libido than single men, while for women, the trend was the opposite – single women reported higher sexual desire than women in partnerships,” described Lucie Slováčková. “For women, higher maternal burden was associated with lower sexual desire, while for men, this effect was reversed,” she concluded.
