Longitudinal study on sexual function and quality of life in infertile couples undergoing intrauterine insemination

Background Cross-sectional studies have shown that sexual dysfunction and poor quality of life were prevalent among couples undergoing assisted reproduction at specific time points, but nothing is known about how these outcomes change over the course of their intrauterine insemination (IUI) journey. Aim We investigated the longitudinal changes in sexual function and quality of life of infertile couples undergoing IUI. Methods Sixty-six infertile couples completed an anonymous questionnaire at 3 time points: after IUI counseling (T1), 1 day before IUI (T2), and 2 weeks after IUI (T3). The questionnaire consisted of demographic data, Female Sexual Function Index (FSFI) or International Index of Erectile Function-5, and Fertility Quality of Life (FertiQoL). Outcomes Descriptive statistics, significance testing with the Friedman test, and post hoc analysis with the Wilcoxon signed rank test were used to compare changes in sexual function and quality of life at different time points. Results Overall, 18 (26.1%), 16 (23.2%), and 12 (17.4%) women and 29 (42.0%), 37 (53.6%), and 31 (44.9%) men were at risk for sexual dysfunction at T1, T2, and T3, respectively. There were significant differences in mean FSFI scores in arousal (3.87, 4.06, 4.10) and orgasm (4.15, 4.24, 4.39) domains at T1, T2, and T3. After post hoc analysis, only the increase in mean orgasm FSFI scores between T1 and T3 was statistically significant. Men's FertiQoL scores remained high during IUI (74.33-75.63 out of 100). Men also scored significantly higher than women on all FertiQoL domains except environment at the 3 time points. Post hoc analysis showed significant improvement in women's FertiQoL domain scores between T1 and T2: mind-body, environment, treatment, and total. Women's FertiQoL score at T2 for the treatment domain was also significantly higher than that at T3. Clinical Implications Men should not be neglected during IUI as their erectile function got worse in the process, with half of the men being affected. Although women's quality of life showed some improvement during IUI, most of their scores were lower than men's. Strengths and Limitations The use of psychometrically validated questionnaires and a longitudinal approach are the major strengths; a small sample size and the lack of a dyadic approach are the major limitations. Conclusion During IUI, women's sexual performance and quality of life improved. The proportion of men having erectile problems was high for this age group, but men's FertiQoL scores remained good and were better than their partners' throughout IUI.
