Male Sexual Quality Of Life Is Maintained Satisfactorily Throughout Life In The Amazon Rainforest

INTRODUCTION: The Amazon Rainforest is a cradle of biodiversity, where different ethnic groups have specific sexual habits. AIMS: To define the average sexual quality of life of Amazonian men 18 to 69 years old, evaluate the influence of aging on their sexual function, and calculate the prevalence of premature ejaculation, delayed ejaculation, and hypoactive sexual desire disorder. METHODS: A cross-sectional quantitative probability sample study was performed with a demographically representative population (N = 385), with data collected privately at participants’ houses, including men who had been sexually active for a minimum of 6 months. The Male Sexual Quotient (MSQ) was used to measure sexual satisfaction and function. Statistical analysis was performed with SPSS 21.0 using the Kruskal-Wallis test (P < .05), and a multiple linear regression analysis was performed to investigate which factors could predict participants’ quality of sexual life. MAIN OUTCOME MEASURES: MSQ scores. RESULTS: The response rate was 81.69%. The mean age was 36.00 ± 12.95 years, and most men had mixed ethnicity (63.11%), were self-employed (42.07%), had a monthly earned income of US$0 to US$460 (46.75%), and were single (36.10%). The mean MSQ score was 80.39 ± 12.14 (highly satisfied). None of the demographic characteristics showed a statistically significant influence on sexual satisfaction. The difference in quality of sexual life was statistically significant compared with age (P < .01). The domains of desire (P < .01), partner satisfaction (P = .04), and erection quality (P < .01, P = .03, P = .02) were statistically significant. Prevalences of sexual dysfunctions were 36.54% for premature ejaculation, 6.5% for delayed ejaculation, and 11.69% for hypoactive sexual desire disorder. CONCLUSIONS: Independent of age, these men have an excellent quality of sexual life. Sexual domains such as desire, partner satisfaction, and erection quality are related to the correlation between sexual quality of life and aging. However, the prevalence of premature ejaculation seems to be slightly higher than in other parts of the world. Teixeira T, Nazima M, Hallak J.
