438 Ioan Scarneciu et al. / Procedia - Social and Behavioral Sciences 127 ( 2014 ) 437 442 1. Introduction Sexuality is a fundamental component of human behavior and has three facets: reproduction, erotic and the relational function that is exercised in accordance with the rules of the social context in which the individual develops. Erectile dysfunction (ED) is the inability to achieve or maintain an erection strong enough for reaching a satisfactory sexual intercourse. The causes of sexual dysfunction are: physical, psychological, mixed or iatrogenic. Triggers and maintaining factors of a disorder usually overlap, making it difficult to delimit a pure cause (Scarneciu & Lupu 2006; Scarneciu & Lupu, 201; Lue 2007; Wespes et. al., 2013; Corona & Maggi, 2012; Porst 2012). One of the risk factors in the development of ED is smoking. Smoking is a major public health problem worldwide. Only two population-based prospective studies have been published on the association between smoking and ED so far (Johannes et al., 2000; Moreira et al., 2003). The Massachusetts Male Aging Study found that the incidence of ED doubled in a sub-group of men free from vascular diseases (Feldman et all 2000). Meta-analysis has shown that 40% of impotent men are current smokers compared with 28% of men in the general population (Tengs & Osgood, 2001). However, there have been controversial reports on association between smoking and ED. Some previous studies have shown that smoking is associated with ED (Martin-Morales, 2001; Gades et al., 2005), but not all (Akkus et al., 2002). Effect of smoking on the incidence of ED is still controversial. Only few longitudinal studies have published so far (Feldman et al., 2000; Elhanbly, 2004). The literature provides ample evidence regarding the association between smoking and male infertility. Reduction was noted in semen quantity, sperm count, motility, and possible morphological changes of spermatozoa (Said et all 2005, American Society for Reproductive Medicine 2012). Infertility is the inability of a couple to achieve a pregnancy in a period of 6-12 months after frequent and unprotected sex. It is estimated that approximately 35-40% of cases of couple infertility is caused by male, in 35-40% of women and 20-30% of cases in other combinations of factors (Jungwirth et al., 2013; American Society for Reproductive Medicine, 2012). Anxiety can cause a reduction in terms of intimacy between partners, avoidance of sexual behavior and intimate nature, the patient seeking to avoid any encounter that might cause a nuisance, a real attempt on his own ego. There are multiple life stressors that can lead to anxiety and in turn induce secondary ED. These stressful events can be job related, couple related, age related, health related or even be side effects from other drug therapies (Wespes, 2013; Porst, 2012). Although not clearly proven involvement of anxiety in male infertility, the occurrence of such problems in man's life will produce anxiety. Men undergo various battles when facing personal infertility, include anxiety concerning potency, masculinity, and sexual adequacy (Zorn, 2007). 2. The present research The present study is based on the observation of many authors, and ours, under which smoking is an important risk factor in the development of sexual dysfunction in men, but also in terms of alterations in semen quality. This study aims to assess whether smoking affects male sexual function, and quality of spermatic fluid. In this research were used questionnaires and semen analysis. 2.1. The motivation of the research The motivation for this study was determined by highlighting profound lack of information for young people about the risk of smoking, regarding the sexual function and infertility. For many infertile man is to blame, although in many cases the man tends not easily accept this problem. 2.2. The research purpose The research purpose of this study was to verify the hypothesis that smoking favors the appearance of sexual dysfunction and altered sperm parameters in young men. A second purpose of this study was to see if the efficiency of a strong message emotionally charged is lower for anxious subjects compared to less anxious, knowing that anxiety is an additional risk factor for the occurrence of ED and is, at the same time, one of the powerful emotional complications of ED.
Ioan Scarneciu et al. / Procedia - Social and Behavioral Sciences 127 ( 2014 ) 437 442 439 2.3. Research objectives The objectives of this research were: highlighting the extent to which smoking favors the appearance of erectile dysfunction highlighting the extent to which smoking promotes alterations in semen quality in young men evaluating behavior that men declare that they will take after disclosure of information highlighting how a highly charged emotional message influences subjects with varying degrees of anxiety assessment of the existence of state and trait anxiety in patients with sexual dysfunction and infertility 2.4. Research hypotheses: smoking is an important risk factor in the development of sexual dysfunction smoking is an important risk factor in the alterations of semen quality in young men the efficiency of a highly charged emotional message will be reduced for anxious subjects compared with the less anxious state and trait anxiety may be involved in the development of sexual dysfunction or male infertility 2.5. The target group: features of the population investigated The study was conducted at the Clinic of Urology, Clinical Emergency County Hospital of Brasov. Study group was chosen at random, unrepresentative, consisting of a total of 250 patients, aged between 18 and 65 years who presented for ED or couple infertility. The inclusion of subjects in the study was based on their voluntary consent. We did not take into account this two factors separately (ED and infertility), our goal is not to determine whether there is a connection between ED and male infertility. 2.6. The experimental plan For evaluating patients with ED, the International Index of Erectile Function (IIEF), an anonymous questionnaire designed in the clinic and STAI scale were used. The advantage of IIEF is that it appreciates separately the different aspects of male sexual function and response: erectile function, orgasmic function, sexual desire, intercourse satisfaction and overall satisfaction (Rosen et all 1997). The anonymous questionnaire used was designed in the clinic and includes 12 items which tried to highlight the presence or absence of certain risk factors for the occurrence of ED and how sexual activity is perceived by each patient. Semen analysis was made according to European Association of Urology guidelines (2 semen analysis serial at 1 month), this being performed in a total of 176 patients (aged up to 40 years). As we said, the cause of anxiety disorders is both sexual dynamics, and rapid onset and long duration thereof. In terms of male infertility, if the possible involvement of anxiety in altered of semen analysis there is still doubt, it is clear that infertility causes anxiety in men and women. In our study, to assess anxiety, we used State-Trait Anxiety Inventory (STAI) (Julian 2011, American Psychological Association 2013). After analyzing all the data, subjects were presented study results, accompanied by results obtained by other studies, which clearly demonstrate the involvement of smoking in the development of ED, as well as semen analysis alteration. Patients were applied the STAI scale and were interviewed on the behavior they will adopt on smoking. Patients were finally divided into two extreme groups: a group with low anxiety and a high anxiety group. All results were statistically analyzed using EpiInfo program.
440 Ioan Scarneciu et al. / Procedia - Social and Behavioral Sciences 127 ( 2014 ) 437 442 2.7. Findings Regarding the involvement of smoking as a risk factor for the occurrence of sexual dysfunction, data analysis revealed: p<0.01, OR=1.2200 with CI95% (0,5209-0,6875). OR=1.2200 indicates, in the presence of statistical significance proving, that smoking favors the appearance of sexual dysfunction in men in our study. Of the total number of semen analysis evaluated (176), they were altered in 123 patients (69.88%) in varying degrees, most of them with azoospermia or astenozoospermia. Of these patients, 62.6% (n=77) are smokers or former smokers, the incidence is higher especially in association with varicocele (37 of smokers had varicocele). The result was statistically significant with p=0.03, but we have to mention that the presence of other risk factors like varicocele were not taken into account separately, the latter representing additional risk factor itself in male infertility. Therefore we recognize that it's likely the results are not a direct result of smoking as a risk factor. Questionnaire on behaviour that they will adopt, 15.6% (n=39) of respondents said they would quit smoking, 34.4% (n=86) will not quit and 41.2% (n=103) as they try, 8.8% (n=22) refused to answer. Subjects stated that they will not stop smoking were questioned as to why this behavior. The responses were varied, but the most common were related to the following: have tried but failed; I do not think that smoking is the cause of their problem; I think that the problem is transient; too late to quit; no apparent reason. To assess anxiety and how patients will respond to a strongly charged emotionally message (made operational through specialized studies presenting data clearly demonstrate the involvement of smoking as a risk factor for ED and infertility), we divided the subjects in the experimental group in the extreme groups, low anxiety (STAI-X1<35 and STAI-X2<41) and high anxiety (STAI-X1>45 and STAI-X2>46). Calculating the difference between the averages showed that for subgroups of anxious and nonanxious, there is no significant statistic difference (p=0.43). In our study, the emotionally charged message did not have a higher effectiveness in nonanxious patients. There are studies that confirm that the efficiency of a highly charged emotional message is reduced for anxious subjects. Although it was not one of our main goals, we tried to evaluate to what extent is anxiety present in patients with ED or male infertility compared with a control group (consisting of 106 persons). The results were: for the STAI-X1 scale the results were statistically significant with, OR=0.2910 with 95%CI (0.054 to 0.668), demonstrating that this anxiety, at some point, is present in these patients (statistically significant result). For the STAI-X2 scale, OR=0.1920 with 95%CI (0.034 to 0.513), results show that the subjects' trait anxiety appears to be implicated in ED or infertility the result is significant for our study. Table 1. Summary of the results Sexual dysfunction Infertility Smoke STAI-X1 (state anxiety) STAI-X2 (trait anxiety) Efficiency of emotionally charged message to anxious or nonanxious subjects p<0.01 OR=1.2200 CI 95% (0,5209-0,6875) OR=0.3123 CI 95% (0,062-0,749) OR=0,2910 CI 95% (0,054-0,668) OR=0,2910 CI 95% (0,054-0,668) OR=0,1920 CI 95% (0,034-0,513) OR=0,1920 CI 95% (0,034-0,513) p>0.05 p>0.05 3. Conclusions Our study clearly demonstrates the involvement of smoking in causing ED, the result being statistically significant. The result is consistent with numerous other studies that highlight the link between this two variables, even in former smokers (Mirone, et al., 2002). There are also numerous authors that show that the link between smoking and ED is still a subject of controversy. Others believe that sustained passive smoking induces sharp changes in penile vasculature thus promoting ED (Otsuka et al., 2001). Also, smoking is responsible for altering semen analysis of patients in our study, the result being statistically significant, but considering the fact that we did
Ioan Scarneciu et al. / Procedia - Social and Behavioral Sciences 127 ( 2014 ) 437 442 441 not consider smoking as a singular risk factor, the result can be influenced by the presence of other risk factors, such as varicocele. The results of this study highlights the semen analysis alteration of smoking patients, particularly in combination with varicocele, perhaps by adding risk factors (we consider other risk factors of course). Although the effects were highlighted by numerous studies and although patients are aware of these effects, a large number of patients do not quit smoking, confirming physical and psychological dependence. As in our study, we see patients every day who realize directly, even in their case, the harmful effects of smoking, but when smoking cessation is being discussed, reluctance or uncertainty in the response is usually, highlighted as the first step (and highest) in continuing the habit. In terms of anxiety, it is the reason of ED`s occurance, but also the effect. The involvement of anxiety in the altering of semen analysis is controversial, but anxiety is usually (for men who are infertile), confusing infertility with masculinity and thus putting so many problems regarding their masculinity. Being a secondary objective, we have not discussed and analyzed ED separately for male infertility in terms of the type of anxiety present in patients, this is the reason why errors can be born from the point of view of statistical interpretation. For this group data analysis revealed that trait anxiety is present in these patients, a statistically significant result for STAI-X2 scale. Also, state anxiety is present in these patients, resulting in statistically significant STAI-X1 scale. Due to the reason stated above, we can not appreciate which of the two parameters analyzed (ED and infertility) has a higher share. In terms of how patients will respond to a strong emotionally charged message after applying the questionnaires STAI, the conclusion was that the type of anxiety of patients in this group did not significantly affect the efficiency of the emotionally charged message. In view of this conclusion, we wondered if the message that we wanted to be strongly emotionally charged has met all of the requirements for the purpose, as numerous studies have shown that the efficiency of a strongly emotionally charged message is reduced for anxious subjects. Infertility of the couple and ED are real problems with alarmingly increasing incidence worldwide, with increasing life expectancy and risk factor multiplication. The involvement of smoking in the development of many diseases, some with fatal potential, is increasingly proven, and experts and the general population are informed in specialized publications. However, smoking is a habit becoming more common and the age at which this vice debuts is increasingly more tender. Jay Leno said: "For the first time in history, sex is more dangerous than the cigarette afterward." What happens when the two combine? And yet, why don t smokers quit this vice? Maybe Damien Hirst's explanation is a plausible one: "So smoking is the perfect way to commit suicide without actually dying. I smoke because it's bad, it's really simple".
