The present study aimed to estimate the prevalence of female sexual dysfunctions (SD) and determine the most common domain of SD in university students. Also, to explore the association between sexual function domains and sociodemographic characteristics, lifestyle, clinical conditions, and type of relationship.

This was a cross-sectional study on a convenience sample of 123 female students. Data were collected by a questionnaire made available online between March and June 2020. The questionnaire included questions for sample selection and characterization. Sexual function was evaluated through the Female Sexual Function Index (FSFI). The FSFI assesses 6 domains of sexual function: desire, arousal, lubrication, orgasm, satisfaction, and pain. The total score varies between 2 to 36 and a score less than or equal to 26 indicates sexual dysfunction 1. The chi-square test was applied to compare background participants’ characteristics with and without SD. The Mann-Whitney U test or the Kruskal-Wallis test were used to analyze the association between participants' variables and FSFI domains. The level of significance for all statistical tests was 5%.

One hundred sixty women fulfilled the questionnaire and 37 were excluded (no sexual activity in the previous 4 weeks). The median age (Interquartile range) of study participants was 23(2) years. The vast majority were nulliparous (n=121; 98.4%) and heterosexual (n=117; 95.1%). One third (n=40; 32.5%) were classified with SD. 

Background variables for participants with and without sexual dysfunction are listed in Table 1.
The majority of the participants had normal body mass index (BMI). Regarding lifestyle habits, almost half reported to be involved in regular exercise practice, the majority was non-smokers and reported the consumption of alcoholic beverages. Concerning health conditions, the majority used hormonal contraceptive methods, and few have irregular menstrual cycles, urogynaecological conditions, and comorbidities. Also, the majority referred to have a stable relationship. There was no statistically significant difference in the reported variables between women with or without sexual dysfunction (Table 1).

The results of the association between BMI, lifestyle habits, health conditions, type of relationship, and the different domains of the FSFI are presented in Table 2. Regarding lifestyle habits, no smoking habits were associated with the orgasm domain. Concerning health conditions, the presence of comorbidities and urogynaecological diseases was associated with the lubrication domain. Be in a stable relationship was associated with the orgasm and the satisfaction domains (Table 2).

The present study included young women. Approximately one-third of the participants were classified with SD, a slightly lower prevalence rate than reported in a previous study in a similar population 2. 
Concerning BMI, lifestyle habits, health condition, and type of relationship, no differences were found between women with and without SD. The women's sexual response is complex and psychosocial factors should be also considered.

Non-smokers had better scores in the orgasm domain than smokers. This finding is not consensual in the published literature. The same trend was observed in the lubrication domain in those with no comorbidities and no urogynaecological diseases.

Being in a stable relationship had a positive impact on the orgasm and the satisfaction domains. Despite orgasm is related to organic factors and satisfaction with psychological factors, some studies demonstrated that both can be associated.

Sexual dysfunction is a common finding among young women. These findings can help to create further awareness of sexual dysfunction in society. On the other hand, contributes to the knowledge about modifiable factors related to sexual health. Counseling and guidance about lifestyle changes can positively impact the sexual function of young women.
