Erectile Dysfunction and Extramarital Sex Induced by Timed Intercourse: A Prospective Study of 439 Men

Abstract

During the fertile window of a woman's menstrual cycle, the effect of impending timed intercourse (TI) on the psychological well-being and behavior of male partners has not been thoroughly investigated, despite the fact that men comprise one half of each couple endeavoring to achieve natural conception. This prospective study consisting of 439 men was conducted during a 3-year period between July 1, 2008, and June 30, 2011. Various characteristics were evaluated, including newly acquired erectile dysfunction (ED); extramarital sex (EMS); intake of soft drinks (SD); levels of hormones, such as follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), prolactin, and estradiol (E2); and semen parameters. A total of 188 men (42.8%) experienced ED and 47 men (10.7%) engaged in EMS. As the number of TI episodes increased, the number of men with ED and EMS and those who wanted to avoid TI also increased (all, P , .0001). All 47 men who reported EMS experienced ED with their spouses. Men who consumed SDs produced significantly smaller volumes of semen (P 5 .0363). Among the hormones investigated, the levels of LH, T, and E2 were significantly lower in men with ED (all, P , .05) whereas the level of FSH was higher in contrast to E2, which was significantly higher in men who had EMS (both, P , .01). TI imposes a great deal of stress on male partners evoking ED and, in some cases, causing these men to seek EMS. Physicians and clinicians should acknowledge the potential harmful effects of TI on men. Furthermore, both female and male partners should also be cautioned about the increased possibilities of ED and EMS as TI incidents increase.

Sexual dysfunctions induced by stress of timed intercourse and medical treatment

“…Table 1 summarizes the ED and DE incidences by TI frequency. Table 2 shows the BAI and BPAQ scores of our study cohort, and Table S1 shows the basic characteristics of the men with ( n = 188) and without ( n = 251) ED as reported in a previous paper [13]. The LH, testosterone and E2 levels differed significantly between the two groups ( P = 0.013, 0.004 and <0.001, respectively).…”

“…A 7%–15% ED prevalence has been reported among adults in Asian studies [15]. The ED details of our study participants have been fully discussed in a previous paper [13]. In this study, we focused on the responses to tadalafil treatment and BAI and BPAQ scores of the men with TI‐related ED.…”

“…Cortisol, the product of the HPA axis, may also reduce testosterone by suppressing gonadotropin‐releasing hormone production and luteinizing hormone (LH) [12]. The impact of impending TI on sexual dysfunction and the behaviour of male partners has only recently been investigated [13], however, even though one‐half of each couple attempting natural conception is a man. In this study, we further investigated men with ED, including those receiving medical interventions (such as tadalafil) and those with EjD.…”

Female Sexual Dysfunction and Timed Intercourse: A Prospective Study of 105 Infertile Women

“…Incorrect timing of intercourse may affect a couple's ability to conceive, but timed intercourse (TI) may associate with adverse aspects. For example, the study showed that as the number of TI episodes increased, the number of men with erectile dysfunction and extramarital sex and those who wanted to avoid TI also increased [4]. The effect of TI on the female sexual function has not been thoroughly investigated.…”

Ovulation monitoring and fertility knowledge: Their relationship to fertility experience in a cross‐sectional study

“…A high risk of bias was found in three of the studies due to recruitment difficulties, incomplete outcome data and involvement of the manufacturer of the ovulation detection method, with all studies likely to suffer from a bias in self‐reported pregnancy due to the impossibility of blinding . Furthermore, recent research on the impact of timed intercourse on men suggests the practice may increase the likelihood of negative outcomes such as erectile dysfunction and extra‐marital relationships . Only one other study evaluated possible harm through recommending urinary test kits, finding no difference in the subjective stress measures over the course of two menstrual cycles among 210 women trying to conceive.…”
