Abstract
Objective:
To study the differences in sexual dysfunction and time to pregnancy (TTP) between infertile couples pursuing timed intercourse (TI – around the time of ovulation) and regular intercourse (RI – at least twice a week).
Methods:
In this prospective cohort study, we recruited all infertile couples presenting to the regional infertility clinics from January 2016 to December 2018, pursuing TI (n = 283) or RI (n = 88), and having no pre-existing sexual or psychiatric illness, and no medical contraindications to frequent intercourse. Sexual dysfunction was assessed using the Arizona Sexual Experience Scale and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. The couples for whom natural conception was possible were followed up to determine TTP using Kaplan–Meier analysis.
Results:
TI significantly increased the risk of sexual dysfunction than RI for both males and females, even after adjusting for age, medical disorders, obesity, smoking, cause of infertility, and previous assisted reproductive techniques. TI increased the risk of erectile dysfunction, premature ejaculation, male hypoactive sexual dysfunction, female sexual interest-arousal disorder, and female orgasmic disorder. The TTP for natural conception was similar between them.
Conclusion:
TI increased the risk of sexual dysfunction without accelerating the time to achieve pregnancy, compared with RI.
