Coital Frequency and Lifespan Relationship
There are no direct research papers that establish a relationship between coital frequency and lifespan. However, several studies have investigated coital frequency in relation to various factors such as infertility, age, and relationship quality.
Factors Influencing Coital Frequency
- Age: Studies have shown that coital frequency decreases with age 1, 2. Older men have been found to have lower coital frequencies, with a 1.05 times higher odds of less frequent coitus per year of age 2.
- Infertility: Coital frequency has been found to be closely related to infertility risks, with a general downward trend in sexual frequency among infertile couples 1.
- Relationship Quality: Relationship quality, as assessed by the female partner, has been found to be a significant predictor of coital frequency 3.
- Erectile Function: Better erectile function has been found to be associated with more frequent coitus among infertile men 2.
- Education and Income: Education and income levels have been found to influence coital frequency, with higher education and income levels associated with higher coital frequencies 3.
Coital Frequency Trends
- A study of infertile Chinese couples found that the proportion of couples reporting having engaged in sexual intercourse >4 times/month fell over the past decade from 62.7% to 52.7% 1.
- A study of Swedish school adolescents found that boys and girls have different coital experiences, with girls having a higher average number of experiences with intercourse during the last month and being more satisfied with how often they have intercourse 4.
- A study of married and cohabiting couples in the United States found that coital frequency decreases with relationship duration and increases with male partner's self-assessed health 3.
