Impact of nasal polyposis on erectile dysfunction
ABSTRACT Our male patients with chronic rhinosinusitis with nasal polyposis (NP) declare a better sexual function after functional endoscopic sinus surgery (FESS) with polypectomy. This study was planned to conduct the first prospective, controlled trial evaluating the possible relation between erectile dysfunction (ED) and NP by subjective and objective parameters.
Thirty-three male patients with NP and thirty randomly selected male control subjects were evaluated. All subjects underwent assessments of nasal endoscopy, rhinomanometry, body mass index (BMI), Epworth Sleepiness Scale, full in-laboratory polysomnograpy and serum levels of glucose, thyroid hormones, lipid profile, and testosterone. ED was evaluated by the erectile function domain of the International Index of Erectile Function (IIEF-EF) subjectively and nocturnal penile tumescence (NPT) objectively. The NP group was reassessed 6 months after FESS.
The mean age, BMI, and laboratory tests of the patients and the control subjects had no significant difference. The well-recognized risk factors for ED were eliminated. Preoperative evaluation of the patients revealed that ED was present in 34 and 24% of the patients by IIEF-EF and NPT, respectively, which was significantly higher than the control group (p = 0.009 and p = 0.018, respectively). There was a significant improvement of ED in the assessment of IIEF-EF and NPT postoperatively (p = 0.014 and p = 0.037, respectively).
ED was determined in a high percentage of patients with NP and significantly ameliorated after FESS. NP might present a risk factor in the development of ED.

ABSTRACT: Olfactory receptors were found to be expressed also in human sperm giving rise to the hypothesis that they might play a role in fertility and sexual behavior. For instance, bourgeonal was demonstrated to be an agonist of sperm cells olfactory receptor, OR1D2. OR1D2 has been found to be expressed in human olfactory epithelium and to play a critical role in human sperm chemotaxis. Recent preliminary evidence showed that olfaction sensitivity (determined by n-butanol olfactory threshold) and sexual desire were associated in young adult males. It is reasonable to hypothesize that bourgeonal olfactory threshold could be related with human sexual behavior and desire. In 37 healthy young adult male volunteers (age range 20-36years), the bourgeonal odor threshold and the intensity of sexual desire [the latter using the International Index of Erectile Function (IIEF) scale] were examined. In addition, samples of DNA were collected. Allele and genotype frequency of the OR1D2 single nucleotide polymorphisms (SNPs) were then evaluated in order to study the relationship between sexual desire and OR1D2 SNPs expression. The olfactory threshold was categorized as <10, 10⩽threshold<15, 15⩽threshold<20, ⩾20. IIEF 1 and IIEF 2 scores were significantly associated. IIEF1 scores, but not IIEF2 scores were significantly associated with olfactory threshold. No statistically significant associations were found neither between genotypes frequency and sexual desire (IIEF1 and IIEF2), nor between genotypes frequency and olfactory threshold. Hypothesizing for the first time the relationship between bourgeonal olfactory sensitivity and sexual desire in a group of young adult males, the present study found a significant association between lower olfactory threshold for bourgeonal and stronger sexual desire, in terms of IIEF1.

ABSTRACT: Nasal polyposis (NP) is a chronic inflammatory disease of unknown etiology that impairs quality of life (QoL). The role of atopy in NP is not established. The aim of this study was to describe the clinical characteristics and QoL in a broad sample of patients with NP and to evaluate the influence of allergy on this disease. A multicenter, observational, cross-sectional study was conducted in 67 allergy units in Spain. NP and nonsteroidal anti-inflammatory drug (NSAID) hypersensitivity were diagnosed following EP(3)OS guidelines. Rhinitis and asthma were classified following Allergic Rhinitis and Its Impact on Asthma and the Global Initiative for Asthma guidelines, respectively. Skin tests with a battery of aeroallergens were performed on all patients. A visual analog scale (VAS) and Short-Form 12 (SF-12) and 31-item Rhinosinusitis Outcome Measure (RSOM 31) questionnaires were completed by all the patients. Of the 671 patients included, 611 were evaluable. Mean age was 46 years and 50% of patients were men. Also, 50% were atopic. Asthma was present in 66% of patients and NSAID hypersensitivity was present in 26%. The most frequent symptoms were nasal congestion and rhinorrhea. Mean value of VAS was 58.6. Global health and bodily pain were the items most frequently identified in the SF-12 questionnaire and nasal and ocular symptoms in the RSOM-31 questionnaire. There was a good correlation between VAS score and QoL (p < 0.0001). Rhinitis was more severe in nonallergic patients. Asthma was more frequent in atopic patients, whereas ASA triad was more frequent in nonatopic patients. Atopic patients showed higher VAS scores and worse QoL. Atopic NP patients showed worse QoL, higher incidence of asthma and a less severe form of rhinitis than non-atopic patients.American Journal of Rhinology and Allergy 09/2012; 26(5):126-31.

ABSTRACT: BACKGROUND: It has been suggested that olfaction could influence human sexual behavior. Age is negatively associated with many aspects of sexuality and, with increasing age, people tend to show a declining sexual desire. The present pilot study investigated the relationship between sexual desire and olfactory sensitivity in healthy men of two age groups, young adult and elderly (≥65 years old), to ascertain whether their sense of smell could determine sexual desire and whether an age-related weaker olfactory sensitivity could correlate with the decline in sexual appetite in elderly patients. METHODS: Sixty-three volunteers were recruited and divided into two groups, one consisting of 48 healthy young adult men, the other of 15 healthy elderly men. All participants were tested to ascertain their odor threshold for n-butanol (Sniffin' Sticks) and their sexual desire using the International Index of Erectile Function (IIEF), presenting only the questions relating to frequency (IIEF1) and level (IIEF2) of sexual desire. RESULTS: Sexual desire and mean olfactory thresholds were higher in the younger adults than in the elderly men (p = 0.001 and p = 0.02, respectively). There was a significant association between butanol threshold and sexual desire for the young adult group (p = 0.02), but not for the elderly group (p = 0.35). CONCLUSION: This study found a preliminary association between olfaction and sexual behavior, in young adults at least. More studies are needed to improve our knowledge in this intriguing field, possibly using electrophysiological olfactory methods.American Journal of Rhinology and Allergy 05/2013; 27(3):157-161.
