Abstract
Noonan syndrome (NS) is a genetic disorder characterized by multiple congenital defects caused by mutations in the RAS/mitogen-activated protein kinase pathway. Male fertility has been reported to be impaired in NS, but only a few studies have focused on fertility status in NS patients and underlying mechanisms are still incompletely understood. We describe the case of a 35-year-old man who underwent an andrological evaluation due to erectile dysfunction and severe oligospermia. A syndromic facial appearance and reduced testis size were present on clinical examination. Hormonal evaluation showed normal total testosterone level, high FSH level, and low-normal AMH and inhibin B, compatible with primary Sertoli cell dysfunction. Genetic analysis demonstrated the pathogenetic heterozygous variant c.742G>A, p.(Gly248Arg) of the LZTR1 gene (NM_006767.3). This case report provides increased knowledge on primary gonadal dysfunction in men with NS and enriches the clinical spectrum of NS from a rare variant in the novel gene LZTR1.

Abstract
INTRODUCTION Medullary thyroid cancer (MTC) is a rare endocrine tumor, which can be sporadic or familial, as a component of multiple endocrine neoplasia 2 (MEN2). Overall, 10% of MTC cases have already developed at presentation or will develop metastasis during follow-up. Testicular metastases are exceptional and only one case of unilateral testis involvement by metastatic MTC has been already reported in literature. We described the first known case of asymptomatic bilateral testicular MTC metastases, discovered incidentally at testicular ultrasound (US) performed for unrelated reasons. CASE PRESENTATION A Latin American 32-year-old man with MEN 2A syndrome and metastatic MTC underwent andrological and urological examination due to premature ejaculation. US imaging showed two symmetrical hypoechoic lesions involving both testes. Suspecting a bilateral testicular cancer, the patient underwent excision biopsy of both testicular lesions. Histopathology and immunohistochemical examinations documented metastatic MTC of both testicular lesions. CONCLUSION Beyond its rarity, testis should be considered as a potential metastatic site of MTC, especially in patients with advanced disease. ESTABLISHED FACTS Distant metastases are present at the diagnosis in 10-15% of patients with medullary thyroid carcinoma (MTC). Testicular metastases are anecdotal. Only one case of unilateral testis involvement by metastatic MTC has been reported in the literature. NOVEL INSIGHTS Testis should be considered as a possible site of metastases in patients with diffuse metastatic MTC. Testicular ultrasound could be considered as an useful tool for the evaluation and follow-up of metastatic MTC.

Abstract
PURPOSE To meet clinicians' request for adequate results and reliable reference ranges for testosterone, this study was planned with the aims (i) to verify the reliability of the reference interval for total testosterone (TT) declared by immunoassay manufacturer and adopted by laboratory, (ii) to compare results for serum TT obtained by immunoassay and LC-MS/MS and (iii) to verify if the cutoff values for low TT and measured free testosterone (FT), defined by Endocrine Society Guidelines for diagnosis of hypogonadism, are applicable to our study group. METHODS Sera from anonymous young/middle-aged male blood donors were selected for the study. TT was measured by immunoassay and LC-MS/MS. SHBG was measured by immunoassay and used with albumin concentration to calculate FT according to Vermeulen's formula. RESULTS The reference interval declared by the manufacturer and adopted by the lab was validated. The two methods for TT evaluation correlated very well. TT and FT lower limits at 5th and 2.5th percentile are below the cutoffs reported in the literature for the diagnosis of hypogonadism. CONCLUSIONS The immunoassay currently used in our lab can be considered an adequate tool for TT, but it's essential that clinical data agree with the biochemical ones, particularly in the presence of TT values between the lower limit of reference range and the cutoff values recommended by scientific societies.

Abstract
<i>NR5A1</i> (nuclear receptor subfamily 5 group A member 1) is a transcriptional regulator of adrenal and gonadal development and function. Heterozygous and homozygous <i>NR5A1 </i>mutations have been described in people with 46,XY disorders of sex development (DSD). The clinical, endocrine, and genetic features of four 46,XY subjects with <i>NR5A1</i> genetic variants (2 sisters, 2 boys) from 3 unrelated families are reported. All subjects presented with hypergonadotropic hypogonadism and abnormal pubertal progression. Markers of Sertoli cell function were more affected than those of Leydig cell function. Genetic investigation demonstrated the presence of different heterozygous <i>NR5A1</i> genetic variants. In the boys, pathogenetic<i> NR5A1</i> gene variants were found that had been previously reported. The 2 sisters carried a new genetic variant in exon 4, and in silico analysis and ACMG classification indicated its pathogenicity. The data confirmed that <i>NR5A1 </i>gene mutations may present with variable genital phenotypes. Anyway, reproductive function was always impaired. Any clinical or endocrine data seem to be unable to differentiate these patients from other 46,XY DSD cases, suggesting that molecular analysis must be warranted. In subjects with <i>NR5A1</i> mutations, different decisions in sex assignment may permit satisfying somatic and psychological outcome, but any option requires hormonal substitutive therapy from adolescence onward.

Abstract
BACKGROUND Proxelan® and antibiotics combined therapy was successfully previously used in the treatment of symptoms of patients with chronic prostatitis. Aim of the present study was to investigate the effects of Proxelan® monotherapy on pain symptoms of patients with chronic prostatitis (CP) or chronic pelvic pain syndrome (CPPS) in a prospective pilot study. METHODS Thirty consecutive patients with CP/CPPS symptoms younger than 50, without urinary obstruction, total prostate-specific antigen (PSA) <4 ng/mL, negative microbiology testing on prostate fluid and urethral swab, naïve from other treatments during the previous three months were enrolled in a pilot study. IPSS and NIH-CPSI questionnaires were administered to all the patients. Patients could choose to be investigated regarding semen quality and IL6/IL8 seminal markers for inflammatory disease prior and after the therapy course. Proxelan® suppositories were prescribed for each patient for a month with a daily dosage of 1 suppository at bed-time. The primary endpoint of the study included at least a 30% reduction of pain symptoms because similar results can be obtained in each previously investigated placebo group. Effects on semen parameters such as leukocytospermia, spermatozoa concentration and motility, cytokine levels were considered as secondary endpoints. RESULTS Subjective pain relief was obtained in all the patients with significant decrease of NIH-CPSI pain items (P=0.04). Urinary symptoms, investigated by IPSS questionnaire, decreased significantly (P=0.04) as well as quality of life items (P=0.04). Leukocytospermia was found in 5/15 patients available for further investigations. IL6 decreased by 11.55% one month after the treatment while sperm motility resulted increased by 17.3%. CONCLUSIONS Proxelan® monotherapy may represents a promising valid alternative to combined treatment with antibiotics in patients with CP/CPPS symptoms although the results obtained should be investigated in randomized controlled trials.

Abstract
Monoterpenes are the main components of essential oils. Some members of this chemical family present insecticidal activity. Triatoma infestans (Klug) is the main vector of Chagas disease in Argentina, Bolivia, Paraguay, and Perú. The objective of this work was to evaluate the effect of six monoterpenes (1,8-cineole, eugenol, linalool, menthol, α-terpineol, and thymol) on the locomotor and flushing out activity of T. infestans. A video tracking technique was used to evaluate the locomotor activity of nymphs exposed to different concentrations of these chemicals applied as films on filter paper. Papers treated with acetone alone were used as negative controls, while solutions of tetramethrin were applied as positive controls. Only linalool and menthol produced hyperactivation. Flushing out was assessed under laboratory conditions using a standardized aerosolization method. All monoterpenes were applied at 1.5 g/m3. 1,8-Cineole, α-terpineol, and thymol flushed out 10% or less nymphs. The average flushing out produced by eugenol was 36.7%. Values of median flushing out time (FT50) could only be calculated for linalool and menthol (16.67 and 42.98 min, respectively). The FT50 value for the positive control tetramethrin (applied at 0.006 g/m3) was 8.29 min. Following these results, the flushing out activity of a mixture of linalool and eugenol was evaluated. The FT50 of this 2:1 linalool:eugenol mixture was 40.73 min. Finally, flushing out assays performed in semifield conditions showed similar results to those obtained at the laboratory.

Abstract
Vitamin D deficiency following malabsorptive bariatric surgery can lead to osteomalacia. We report a patient with severe vitamin D deficiency following malabsorptive bariatric surgery successfully treated with calcifediol but not cholecalciferol. A 40-year-old woman, submitted to biliopancreatic diversion 20 years before and chronically treated with 50,000 IU cholecalciferol weekly, was admitted to our Endocrine Unit because of severe lower back pain, muscle weakness, and generalized muscular hypotrophy, associated with hypocalcemia and elevated PTH levels. Initial evaluation revealed low serum albumin, low albumin-corrected serum calcium (7.36 mg/dL), high serum PTH (240 pg/mL), bone-specific alkaline phosphatase (125 μg/L) and 1,25-dihydroxyvitamin D (112 pg/mL) concentrations, undetectable serum 25-hydroxyvitamin D (<7 ng/mL), and evidence of reduced liver function. Bone mineral density was markedly low. Normocalcemia was initially restored with intravenous albumin and calcium gluconate. Treatment with calcitriol (0.5 μg three times daily) and oral calcium carbonate (1000 mg daily) was simultaneously started and cholecalciferol was replaced with calcifediol [125 μg (5000 IU) daily)]. During follow-up the calcifediol dose was progressively tapered to 25 μg (1000 IU) daily and the calcitriol dose was progressively reduced and finally withdrawn. Serum albumin and other biochemical parameters normalized, bone mineral density significantly increased, and the patient's clinical conditions progressively improved, with a substantial recovery of autonomy. Serum vitamin D binding protein at the last observation was in the normal range. Our data suggest that calcifediol might be more efficacious than cholecalciferol for prevention and treatment of vitamin D deficiency in patients treated by malabsorptive bariatric surgery.

Abstract
PURPOSE Management of late onset hypogonadism (LOH) is not homogenous. The aim of the study is to observe the management of patients with low testosterone (T) in highly specialized Italian centres. METHODS The SIAMO-NOI is an observational longitudinal disease registry for the evaluation of the clinical management of patients with low T levels (total T < 12 nmol/L, calculated free T < 225 pmol/l or already in treatment) in 15 Italian centers members of the Italian Society for Andrology and Sexual Medicine (SIAMS). Clinical and biochemical data were collected for four visits during 12 months of observation. RESULTS 432 patients (mean age 50.9 ± 14.9 years) were enrolled. Of them, 247 men were receiving androgen therapy, whereas 145 were naive. After the first visit (V0), 80 men started androgen therapy, whereas 55 remained untreated during the entire observation. Younger age [odds ratio (OR) 0.57 (0.35-0.92)], total T < 8 nmol/l [OR 4.69 (1.59-13.81)], complaining at least one sexual symptom [OR 11.55 (2.01-66.35)] and reporting more severe lower urinary tract symptoms [OR 1.27 (1.01-1.60)] predicted starting an androgen therapy. Sixty-four men started therapy immediately after V0 and maintained it until the observation end. When compared to V0, they reported an increase in all the domains of the International Index of Erectile Function-15 (IIEF-15), in the sexual and physical subdomains of the Aging Male Scale as well as in the International Prostate Symptom Score. Conversely, the untreated group reported a significant improvement, although lower than the treated group, only in the erectile function domain of the IIEF-15. CONCLUSIONS Management of LOH in SIAMS centres is in line with the international guidelines and the newest knowledge about the role of T on prostate health. Androgen therapy is associated with an improvement in all the aspects of sexual life and in the perception of physical strength.

Abstract
OBJECTIVE To evaluate the effects of radioactive iodine (RAI) treatment for differentiated thyroid cancer (DTC) on testis function. DESIGN A prospective longitudinal single-centre study was performed. A comprehensive andrological evaluation including hormonal assessment, semen analysis and scrotal ultrasound was undertaken in male patients undergoing RAI treatment for DTC. METHODS Hormonal assessment of FSH, LH, testosterone (T), sperm concentration and motility and testis volume were determined in 20 patients in basal conditions, 6 and 12 months after RAI. Results were analysed in the whole group of patients and then separately in those who received one single ablative treatment ('Single' group, n = 10) and those who received multiple treatments ('Multiple' group, n = 10). RESULTS In basal conditions, 3 of 20 (15%) patients had a reduced sperm count and belonged to the 'Multiple' group. After RAI, an increase of FSH (8·8 ± 1·2 UI/l vs 5·2 ± 1·2, P < 0·005) and a decrease in sperm concentration (28·8 ± 7·7 millions/ml vs 54·5 ± 7·1, P < 0·005) and testis volume (15·2 ± 3·1 vs 13·7 ± 0·8 ml, P < 0·005) occurred at 6 months in the whole group. One year after RAI, seven patients had oligozoospermia (five from the 'Multiple' group and two from the 'Single' group). Permanent impairment of one or more testis function parameters was observed in patients who underwent multiple RAI treatments: 50% for sperm count, 40% for FSH levels and testis volume and, respectively, in 20 and 10% of those who received one single RAI treatment. CONCLUSIONS The single ablative RAI treatment in cancer patients is better tolerated respect multiple RAI treatments regard testis function. Multiple treatments for recurrent or metastatic disease may cause a permanent impairment of one or more parameters related to the reproductive potential of male patients.

Abstract
PURPOSE We evaluated the ability of the phosphodiesterase-5 inhibitor vardenafil to increase prostate microcirculation during power Doppler ultrasound. We also evaluated the results of contrast and vardenafil enhanced targeted biopsies compared to those of standard 12-core random biopsies to detect cancer. MATERIALS AND METHODS Between May 2008 and January 2010, 150 consecutive patients with prostate specific antigen more than 4 ng/ml at first diagnosis with negative digital rectal examination and transrectal ultrasound, and no clinical history of prostatitis underwent contrast enhanced power Doppler ultrasound (bolus injection of 2.4 ml SonoVue® contrast agent), followed by vardenafil enhanced power Doppler ultrasound (1 hour after oral administration of vardenafil 20 mg). All patients underwent standard 12-core transrectal ultrasound guided random prostate biopsy plus 1 further sampling from each suspected hypervascular lesion detected by contrast and vardenafil enhanced power Doppler ultrasound. RESULTS Prostate cancer was detected in 44 patients (29.3%). Contrast and vardenafil enhanced power Doppler ultrasound detected suspicious, contrast enhanced and vardenafil enhanced areas in 112 (74.6%) and 110 patients (73.3%), and was diagnostic for cancer in 32 (28.5%) and 42 (38%), respectively. Analysis of standard technique, and contrast and vardenafil enhanced power Doppler ultrasound findings by biopsy core showed significantly higher detection using vardenafil vs contrast enhanced power Doppler ultrasound and standard technique (41.2% vs 22.7% and 8.1%, p <0.005 and <0.001, respectively). The detection rate of standard plus contrast or vardenafil enhanced power Doppler ultrasound was 10% and 11.7% (p not significant). CONCLUSIONS Vardenafil enhanced power Doppler ultrasound enables excellent visualization of the microvasculature associated with cancer and can improve the detection rate compared to contrast enhanced power Doppler ultrasound and the random technique.

Abstract
OBJECTIVE To evaluate the acute effect of sildenafil and tadalafil on seminal parameters in young, infertile patients. DESIGN Prospective, randomized, double-blind, crossover clinical investigation on semen parameters after the administration of a single dose of sildenafil (50 mg) or tadalafil (20 mg). SETTING An academic hospital as well as a male infertility center and clinical andrology laboratories. PATIENT(S) Eighteen young, infertile men. INTERVENTION(S) Oral administration of a single dose of sildenafil (50 mg) or tadalafil (20 mg) in a blind, randomized order. The semen samples were collected 1 or 2 hours after each treatment. MAIN OUTCOME MEASURE(S) Changes in sperm parameters after sildenafil and tadalafil administration, compared with the basal conditions. RESULT(S) A significant increase in sperm progressive motility (median value, 37.0% vs. 28.5%) was observed after sildenafil administration as compared with baseline; in contrast, a significant decreased value was observed after tadalafil (median value, 21.5% vs. 28.5%). CONCLUSION(S) These preliminary results indicate that sperm motility appears to be acutely affected in young, infertile patients by a single dose of sildenafil and tadalafil, with opposite effects: stimulatory by the former and inhibitory by the latter.

Abstract
OBJECTIVE Radioiodine-131 is commonly used for treatment of hyperthyroidism but there are few available data on the effects of this treatment on male gonadal function. The untoward effects of (131)I have been mainly studied in male patients treated with high doses for thyroid cancer. In the present work we studied the absorbed radiation dose to the testes and testicular function in hyperthyroid men after (131)I treatment. PATIENTS AND MEASUREMENTS Nineteen male hyperthyroid patients were enrolled in the study before (131)I therapy. Seventeen of the patients had Graves' disease and two had toxic adenoma. The study was subdivided into two parts: a dosimetric and a clinical study. Six patients were enrolled for the dosimetric study and 13 for the clinical study. The beta dose delivered to the testes was evaluated by the Medical Internal Radiation Dose (MIRD) method. The gamma dose was measured by thermoluminescent dosimeters (TLDs) placed on the skin overlying the inferior poles of the testes for 3 weeks after therapy. The clinical evaluation included hormone determination, ultrasound (US) of the testes and sperm analysis. Patients were followed up for 12 months after (131)I therapy. RESULTS In the dosimetric study, the beta dose absorbed in the testes was 12.5 +/- 8.8 mGy (range 29-15 mGy) and the gamma dose was 15.8 +/- 5.3 mGy (range 24-11 mGy). The total dose to the testes for administered activity unit was 39 +/- 14 microGy/MBq (range 27-86 microGy/MBq). In the clinical study, FSH did not change significantly after (131)I treatment for the majority of patients. Serum testosterone (T) and the T/LH ratio were significantly reduced 45 days after treatment and returned to basal levels after 12 months. Ten out of 15 hyperthyroid patients (67%) had low sperm motility before treatment. A significant increase in progressive motility was observed after (131)I therapy (Friedman test chi(2) = 12.65, P = 0.01). Conversely, there was no significant variation in sperm concentration and percentage of normal forms after (131)I. CONCLUSIONS After (131)I therapy, germinal epithelium and Leydig cell function undergo only marginal changes, which may have some significance in subjects with a pre-existing fertility impairment.

Abstract
CONTEXT The contribution of endogenous testosterone (TS) in the functional integrity of peripheral circulation in men was studied. OBJECTIVE The objective of this study was to observe vascular reactivity in male congenital hypogonadal patients before and after prolonged exposure to normal TS levels. DESIGN This was a longitudinal study in which, basically and after 6-month (range, 6-8 months) androgen treatment, we investigated forearm blood flow (strain-gauge plethysmography) changes induced by intraarterial acetylcholine (Ach), alone or in the presence of N(G)-monomethyl-l-arginine infusion, and by sodium nitroprusside. We also evaluated, by Doppler ultrasound, flow-mediated dilation of the brachial artery (BA) in response to reactive hyperemia (RH) and glyceryl trinitrate (GTN). SETTING The studies were conducted at university referral centers for andrologic and blood pressure diseases. PATIENTS Eight adult male Caucasian hypogonadal patients and nine healthy matched control subjects were studied. INTERVENTION Intervention was TS enanthate (250 mg in 1 ml oily solution) by im injection every 3 wk. RESULTS At baseline, BA diameter and RH, flow-mediated dilation, and GTN responses showed no difference between the two groups. TS therapy increased plasma total TS (P < 0.02) and reduced high-density lipoprotein (P < 0.01) and total cholesterol (P < 0.04). It did not affect vasodilation to sodium nitroprusside (355 +/- 47%), but it further reduced the vascular response to Ach (187 +/- 29%, P < 0.01 vs. baseline) and abolished the inhibition by N(G)-monomethyl-l-arginine on Ach (inhibition, 3.2%). Moreover, TS therapy decreased (P < 0.01) flow-mediated dilation, whereas it did not modify BA diameter and responses to RH and GTN. CONCLUSIONS Hypogonadal patients show impaired vascular reactivity, including endothelial-dependent vasodilation due to reduced nitric oxide availability. TS administration further impairs nitric oxide availability in these patients.

Abstract
BACKGROUND/AIMS Prostatic specific antigen (PSA) is the most specific prostatic tumor marker in man. Recently, PSA has been detected in a variety of tissues and fluids in women, and its determination suggested as a marker of hyperandrogenism. However, precise information about the physiology of PSA in females is not available. The goal of this study was to assess serum concentrations of PSA in healthy pre-menopausal women (healthy pre-menopausal group), menopausal women (menopause group) and patients with polycystic ovary syndrome (PCOS group). METHODS PSA, androgens, LH, FSH, 17-beta-estradiol (E2), progesterone (Pg) were assessed in 40 post-menopausal women, 35 fertile controls and 35 women with PCOS. RESULTS No significant difference in PSA concentrations could be demonstrated in different phases of the menstrual cycle in healthy pre-menopausal group and between pre- and post-menopausal groups. No correlations could be demonstrated between serum PSA levels and the following parameters: age, body mass index (BMI), LH, FSH, E2, testosterone (T), DHEAS, and SHBG, both in pre- and post-menopausal women. Significantly higher PSA levels (median=14 pg/ml) were found in the PCOS group compared to both pre-menopausal (median=5 pg/ml) and menopausal (median= 5 pg/ml) groups (p< 0.05). CONCLUSIONS only minor fluctuations of serum PSA concentrations are observed in healthy pre- and post-menopausal women, while serum level is higher in PCOS, and therefore PSA can be considered a suitable marker of female hyperandrogenism.

Abstract
OBJECTIVE To better define by molecular and cytogenetic techniques ring Y chromosomes detected in 2 infertile men. DESIGN Case report. SETTING Molecular genetics/cytogenetics unit in a university hospital. PATIENT(S) Two infertile men with azoospermia, presenting a normal male phenotype with complete masculinization. INTERVENTION(S) Karyotype and genetic counseling. MAIN OUTCOME MEASURE(S) Metaphases were studied by standard G- and Q-banding; fluorescent in situ hybridization and PCR were performed to analyze specific Y chromosome regions. RESULT(S) Chromosomal analysis detected a mosaicism with a Y chromosome ring cell line in 92% (patient 1) and 95% (patient 2) of the metaphases, coexisting with a 45,X cell line in the remaining metaphases. In patient 1, PCR analysis showed the presence of AZFa region and a partial deletion of AZFb region; AZFc region was deleted. In patient 2 all three AZF regions were deleted. CONCLUSION(S) A 45,X/46,X,r(Y) mosaicism can be detected not only in patients with Ullrich-Turner syndrome and in patients with various degrees of genital ambiguity but also in men presenting a normal phenotype. Their azoospermia can be explained by partial or total deletion of AZF regions.

Abstract
Objective Polymorphism of the androgen receptor (AR) has been related to various pathophysiological conditions, such as osteoporosis and infertility. The objectives of this study were to evaluate the frequency of distribution in a normal Italian population and to assess CAG repeats (CAGr) in other conditions, such as hypoandrogenism, potentially influenced by AR polymorphism. Patients and measurements CAGr polymorphism was determined in a group of 91 healthy normoandrogenized subjects, 29 hypoandrogenized patients (hypoplasia of prostate and seminal vesicles, reduced beard or body hair, etc.) and 29 infertile patients by direct sequencing. Results The mean (+/- SD) number of CAG repeats [(CAGr)n] was 21.5 (+/- 1.7) in the control group, 21.4 (+/- 2.0) in the infertile patients and 24.0 (+/- 2.9) in the hypoandrogenic males. The difference was statistically significant between this last group and the other two (P < 0.0001), while there was no difference between normal controls and infertile patients. The frequency distribution showed a shift towards higher CAG length in hypoandrogenized patients compared to controls and infertile patients. If we used a cut-off point of 24.9 (2 SD above the mean), the percentage of patients with 25 or more CAGr repeats was 38% among hypoandrogenized patients, 7% among infertile patients and 5% among the control group. In hypoandrogenized subjects (CAGr)n correlated slightly with testis and prostate volume. The number of CAG repeats was not associated with any of the hormonal parameters, including testosterone, evaluated in the three groups. Conclusions Our normal population, representing subjects from Central Italy, is superimposable on other European populations with regard to (CAGr)n distribution. Hypoandrogenic males have a shift in the frequency distribution towards longer (CAGr)n. Infertile patients are not statistically different from the control group. These findings suggest that, given the same amount of circulating testosterone, as in our hypoandrogenized and control group, the final net androgenic phenotypical effect is due to AR polymorphism.

Abstract
To fall in love is the first step in pair formation in humans and is a complex process which only recently has become the object of neuroscientific investigation. The little information available in this field prompted us to measure the levels of some pituitary, adrenal and gonadal hormones in a group of 24 subjects of both sexes who had recently (within the previous six months) fallen in love, and to compare them with those of 24 subjects who were single or were part of a long-lasting relationship. The following hormones were evaluated by means of standard techniques: FSH, LH, estradiol, progesterone, dehydroepiandrosterone sulphate (DHEAS), cortisol, testosterone and androstenedione. The results showed that estradiol, progesterone, DHEAS and androstenedione levels did not differ between the groups and were within the normal ranges. Cortisol levels were significantly higher amongst those subjects who had recently fallen in love, as compared with those who had not. FSH and testosterone levels were lower in men in love, while women of the same group presented higher testosterone levels. All hormonal differences were eliminated when the subjects were re-tested from 12 to 24 months later. The increased cortisol and low FSH levels are suggestive of the "stressful" and arousing conditions associated with the initiation of a social contact. The changes of testosterone concentrations, which varied in opposite directions in the two sexes, may reflect changes in behavioural and/or temperamental traits which have yet to be clarified. In conclusion, the findings of the present study would indicate that to fall in love provokes transient hormonal changes some of which seem to be specific to each sex.

Abstract
Thyroid hormone (TH) is involved in the differentiation and development of rat testis, whereas its role in adult testis function is still undefined. The aim of our work has been to further analyze the presence in the testis of rats of various ages of messenger RNA (mRNA) coding the different TH receptor (TR) subtypes using a sensitive assay, such as reverse transcriptase-polymerase chain reaction (RT-PCR). To rule out the possibility of an "illegitimate transcription," we have analyzed both T3-binding capacity of adult rat testis and the presence in the same organ of TR proteins by immunohistochemistry, using specific antibodies directed against the various TR isoforms. Messenger RNA coding for TR alpha1 and alpha2 isoforms was clearly visible in gels prepared from RT-PCR samples obtained from the testis of rats of all ages, including adults, whereas mRNA for the TR beta1-beta2 was absent. The T3 maximal binding capacity (Cmax) by nuclear extracts of testicular homogenates gradually decreased from birth to adulthood, still remaining significantly detectable in adult testis, and represented approximately 1% of the Cmax observed in the liver. The immunostaining technique revealed an intense nuclear staining along the basement membrane of testicular tubules prepared from rats of all ages and incubated with an antipeptide antibody specific for TR alpha1 (alpha1-403). Staining with an antipeptide antibody specific for TR beta1 (beta-62) was never present. Our data show that mRNAs coding for the functional TR alpha1, and also for the still undefined alpha2, are present in the testis of rats of all ages. T3-binding activity and immunohistochemical studies confirmed that the message is translated into proteins. The transcriptional activity clearly decreased from birth to adulthood, but it still remained significantly present. The presence of a TR alpha1 message indicates that the adult rat testis may be directly responsive to T3 and, therefore, suggests an action of TH on rat testis that is not only developmental, but also metabolic.

Abstract
BACKGROUND The presence of a spermatogenesis locus (gene or gene complex) in the euchromatic region of the long arm of the Y chromosome (Yq11), defined as azoospermia factor on the basis of gross structural rearrangement, was detected. The gene family responsible for different spermatogenetic defects is "deleted in azoospermia" (DAZ). CASE A 34-year-old man had oligozoospermia, and a cytogenetic analysis carried out on peripheral lymphocytes with G banding revealed a 46,X, inv(Y)(p11q11)karyotype. The relation between the chromosomal breakpoint and the DAZ gene was more precisely defined by a fluorescent in situ hybridization technique. We revealed two signals for the DAZ gene, weaker than normal, one on the short arm and the other on the long arm of the Y chromosome, indicating that the breakpoint was located at the DAZ gene level. CONCLUSION This is the first report documenting a chromosomal pericentric inversion with disruption in the DAZ gene area. We hope to obtain information on whether the disruption affects a functional zone of the gene and correlates with oligospermia at the chromosomal level.

Abstract
We investigated 22 male patients affected by prepubertal hypogonadism with a mean age of 34.3+/-5.2. A significant reduction of bone mineral density (BMD) at both the lumbar spine (L2-L4, -14%, 1.039+/-0.11 vs. 1.217+/-0.16 g/cm(2), P=0.005) and femoral neck (-11%; 0.927+/-0.09 vs. 1.034+/-0.16 g/cm(2), P=0.01) was found in patients compared to age-matched controls. The mean Z score was -1. 55 for vertebrae and -1.33 for femur. Eleven and nine patients, respectively, had a lumbar and femoral BMD at least 1 S.D. below the normal mean; 8 and 4, respectively, 2 S.D. below. There was a strong positive correlation between BMD and duration of hormone replacement treatment (HRT) for both sites: respectively, r=0.71, P<0.005 for the vertebrae, and r=0.60, P<0.01 for the femur. A weak correlation was also present between onset of HRT and BMD: r=0.6, P<0.01 at the lumbar level, and r=0.47, P<0.05 at the femoral neck.

Abstract
We tested experimentally the effects of the presence of non-susceptible hosts on the infection with Trypanosoma cruzi of the vector Triatoma infestans. The experiment consisted in two treatments: with chickens, including two chickens (non-susceptible hosts) and two infected guinea pigs (susceptible hosts), and without chickens, including only two infected guinea pigs. The hosts were held unrestrained in individual metal cages inside a closed tulle chamber. A total of 200 uninfected T. infestans third instar nymphs were liberated in each replica, collected on day 14, and examined for infection and blood meal sources on day 32-36. The additional presence of chickens relative to infected guinea pigs: (a) significantly modified the spatial distribution of bugs; (b) increased significantly the likelihoods of having a detectable blood meal on any host and molting to the next instar; (c) did not affect the bugs' probability of death by predation; and (d) decreased significantly the overall percentage of T. infestans infected with T. cruzi. The bugs collected from inside or close to the guinea pigs' cages showed a higher infection rate (71-88%) than those collected from the chickens' cages (22-32%). Mixed blood meals on chickens and guinea pigs were detected in 12-21% of bugs. Although the presence of chickens would decrease the overall percentage of infected bugs in short term experiments, the high rate of host change of T. infestans would make this difference fade out if longer exposure times had been provided.

Abstract
Resistance to thyroid hormone (RTH) is almost invariably associated with mutations of the thyroid hormone (TH) receptor beta (hTR beta) gene and is inherited as an autosomal dominant disease. Mutations of hTR beta identified in patients affected by RTH cluster generally at two spots of the ligand binding domain. We investigated whether an Italian kindred with RTH had a mutation in the thyroid hormone (TH) receptor beta gene. Blood samples were obtained from the available family members for biochemical and genetic analyses. Thyroid function tests in basal conditions, and in the case of the propositus also following incremental doses of T3, were performed. Exon 4 to 10 of hTR beta gene were amplified using the polymerase chain reaction (PCR) and the mutation was identified by direct sequence analysis. The affinity constant of this mutated receptor for T3 was measured by in vitro transcription-translation and was then compared with that of wild type. We identified a heterozygous G to A transition at nucleotide 1037 of exon 8 at codon 251, resulting in a glycine (G) to glutamic acid (E) substitution (G251E) in the patient affected by RTH and in his affected offspring, but not in the normal family members. This novel mutation represents a de novo mutation since both parents of the index case were unaffected and did not have this genomic mutation. When expressed in vitro, the mutant protein (G251E) showed a marked decrease of the affinity for T3, suggesting an impaired ligand-dependent transactivation activity of this mutant receptor. In vivo studies with incremental doses of L-T3 demonstrated a reduced sensitivity to TH in the index case, in particular at the pituitary level where the thyrotrophs' activity was not completely inhibited even by 200 micrograms/day of L-T3. G251E mutation represents the fourth mutation described up to now in exon 8 of hTR beta among the subjects affected by RTH. A third cluster of mutations of the c-erbA beta gene located proximally with respect to the other two so far described begins to emerge in RTH patients.

Abstract
Three species of triatomine bugs, Triatoma sordida, T. guasayana, and T. patagonica, were examined by cytogenetic (C-banded karyotypes and male meiotic process) and isoenzymatic studies. These three species, with different importance as Chagas' disease vectors, were found to be closely related according to their known ethologic, ecologic, and morphologic traits. Although they have the same diploid chromosome number (2n = 22 constituted by 20 autosomes and an XY male/XX female sex mechanism), each species has a distinct chromosomal behavior during male meiosis and a specific amount and localization of C-heterochromatic blocks. Moreover, these chromosome characteristics allowed us to differentiate two T. sordida populations. Isoenzymatic data confirmed the taxonomic status of the three species and together with our cytogenetic results questioned the species homogeneity of T. sordida.

Abstract
The purpose of this study was to identify the origin of Triatoma infestans reinfestation and study its dynamics following spraying with deltamethrin inside and around 94 houses in three rural communities in northwestern Argentina. The effectiveness of the spraying was evaluated immediately after the houses were sprayed and two months later. In addition, five residual peridomiciliary foci were found and sprayed, as well as three preexisting ones that had not been sprayed. To monitor reinfestation, biosensors were placed in the houses and each family was also asked to capture triatomines and keep them in plastic bags; in addition, triatomines were searched for in and around houses, using an aerosol that dislodged them from their hiding places. Selective sprayings were carried out only where a colony of T. infestans was found. During the 30 months of follow-up, the percentage of houses in which any T. infestans were captured varied between 3% and 9%. In six houses, T. infestans were captured during more than one evaluation. The number of peridomiciliary areas found to be infested (19) was double the number of infested houses (9). Colonies of T. infestans were found only in the peridomiciliary areas, where the number of T. infestans captured was six times higher than in the houses. Chickens were the host most frequently associated with peridomiciliary foci. This area was the origin and principal source of reinfestation. To reduce the speed of reinfestation and the frequency with which sprayings are needed, the following environmental and chemical control methods must be combined in the peridomiciliary area: reduce the number of hiding places of triatomines; restrict the raising of birds to structures that cannot be colonized by triatomines; apply an insecticide that is less likely to be degraded by exposure to the elements, or perform a second spraying 6 to 12 months after the first; and employ a device for early detection of the presence of T. infestans around houses.

Abstract
The probability that an uninfected Triatoma infestans would become infected with Trypanosoma cruzi after a single feed on people or dogs seropositive for T. cruzi was estimated in Amama, a rural village in northwest Argentina where transmission had resurged four years earlier. The prevalence of seropositivity for T. cruzi was 34.2% among 225 people tested, and 65.1% among 83 dogs tested. Parasitemia was detected by xenodiagnosis in 29.3% of 41 seropositive persons and in 85.3% of 34 seropositive dogs. Parasitemia decreased with age more sharply in seropositive people than in seropositive dogs. Seropositive humans infected 2.6% (95% confidence interval = 1.6%-3.6%) of 963 third or fourth instar nymphs fed once on them, whereas dogs infected 48.7% (44.7%-52.7%) of 610 nymphs. The probability of bug infection increased significantly with instar and was positively related to molting success. The infectivity to bugs of seropositive dogs was 12 times higher than that of seropositive children, and 100 times higher than that of seropositive adults. The weighted probability of infection of an uninfected bug fed randomly on any dog (0.3082) was about 50 times higher than that of bugs fed on any human (0.0062). Such differences in relative infectivity, combined with the relative host-feeding preference of domiciliary Triatoma infestans for dogs, reinforces the important role of domestic dogs as a risk factor for the domestic transmission of T. cruzi.

Abstract
Intracavernous self-injection with vasoactive drugs has become a widely accepted treatment for erectile dysfunctions (ED). Sixty-eight patients affected by ED have been followed during long-term (at least 1 year) treatment with intracavernous prostaglandin E1. Each patient underwent a penile dynamic ultrasound examination using a high-definition probe (13 MHz) before and during the treatment. The drop-out rate was 8.8%. An improvement in spontaneous erections was reported by 13% of patients. The onset of fibrotic nodules occurred in three (4.4%) patients. In one of the latter cases the occurrence of nodules could be related to the frequency and dose of the drug administered, whereas in the other two cases no such correlation could be hypothesized. These findings draw attention to this possible side-effect of long-term treatment with PGE1.

Abstract
Success in obtaining a blood meal and rapid access to hiding places after feeding are the principal requirements triatomines have as they colonize artificial ecotopes. Feeding success and postfeeding location of 3rd and 5th instars of Triatoma sordida (Stål), of T. guasayana Wygodzinsky & Abalos, and T. infestans (Klug) were studied in an experimental box in which triatomines and a chicken were left to interact overnight. The bird was enclosed in a glass cube, slightly raised to allow triatomines to get in and out, turning the space outside into an extensive refuge area. Four bunches of dry corn husks and a wooden panel were also offered as shelters. The number of live and dead insects and their locations at the end of the experiment were recorded. Predation--as the percentage of missing insects--and success--as the percentage of insects alive and fed--were calculated. Interactions with the host were different among species and sometimes also between individuals of different life stages of the same species. Predation was always > 20%. T. sordida was the best exploiter of the blood source, because 3rd instars were more successful and 5th instars were as successful as the corresponding T. infestans stages. Performance of T. guasayana was equivocal because survival and feeding success were different for both instars. T. infestans showed a pronounced tendency to climb, and 3rd instars of T. guasayana were equally distributed in the upper half of the box and in the corn husks, whereas the majority of T. sordida and 5th instars of T. guasayana sheltered in the husks.

Abstract
This paper compares the predation pressure that ducks and chickens exert on triatomines. For the tests, these birds were placed in individual boxes together with a known number of Triatoma infestans and left to interact from 6 p.m. till the next morning, involving a long lasting period of complete darkness limited by two short-term periods of semi-darkness. There was a shelter which could prevent the bugs from being predated. The number of live and dead triatomines was recorded, considering missing bugs as predated by the birds. Ducks exhibited a greater predatory activity than chickens, that could be due to a long term active period at night while chickens sleep motionless from sunset to dawn. Surviving triatomines that had fed on chickens outnumbered those fed on ducks suggesting that these were less accessible to the triatomine biting. If ducks are better than chickens to detect and eat bugs and to interfere with their feeding in the field, an increase in duck number might help to diminish triatomine density. Further research is needed to determine the feasibility of application of these experimental results.

Abstract
Sperm morphology has been suggested to be one of the most reliable factor in predicting male fertility potential both in spontaneous cycles and in assisted reproduction. In this work the morphology of spermatozoa selected with three different techniques (layering, swimup from pellet and mini-percoll) has been assessed and compared in 20 infertile patients. All the techniques allowed the recovery of sperm populations of a better quality than in basal samples, with a higher percentage of normal forms (p < 0.001). No significant differences were observed among the three different techniques in selecting sperm populations. The scatter diagrams comparing pairwise differences between the methods against their means regard the percentage of normal forms selected show a great (over 20%) inter and intra-individual variability. These data demonstrate that the three techniques select different percentages of normal spermatozoa, even in the same patient. Since it is crucial to obtain the highest number of morphologically normal and motile spermatozoa and each technique may provide different results in a given patient, we suggest that at least two techniques of sperm selection be performed before assisted reproduction procedures. This combined testing could also be relevant in the prognostic evaluation of the infertile male, since it explores the different characteristics of sperm function.

Abstract
The aim of the study described here was to evaluate any possible effect of L-carnitine on spermatozoal motility in a group of patients with unexplained asthenozoospermia in four different infertility centres. One hundred patients received 3 g d-1 of oral L-carnitine for 4 months. Sperm parameters were studied before, during and after this treatment. Motility was also studied by means of a computer-assisted sperm analysis. The results of the study indicate that L-carnitine is able to increase spermatozoal motility, both in a quantitative and in a qualitative manner (per cent motile spermatozoa increased from 26.9 +/- 1.1% to 37.7 +/- 1.1% [P < 0.001]; per cent spermatozoa with rapid linear progression increased from 10.8 +/- 0.6% to 18.0 +/- 0.9% [P < 0.001]; mean velocity increased from 28.4 +/- 0.6 microns s-1 to 32.5 +/- 0.8 microns s-1 [P < 0.001]; linearity index increased from 3.7 +/- 0.1 to 4.1 +/- 0.1 [P < 0.001], especially in the subgroup of patients with poor rapid linear progression of spermatozoa (per cent of motile spermatozoa increased from 19.3 +/- 1.9% to 40.9 +/- 1.4% [P < 0.001], and per cent of spermatozoa with rapid linear progression increased from 3.1 +/- 0.4% to 20.3 +/- 1.6% [P < 0.001]) An increase in spermatozoal output was also observed (total number of ejaculated spermatozoa increased from 142.4 +/- 10.3 10(6) to 163.3 +/- 11.0 x 10(6) [P < 0.001]). The authors conclude that oral administration of L-carnitine may improve sperm quality at least in patients with idiopathic asthenozoospermia.

Abstract
Nimesulide, a novel non-steroidal anti-inflammatory drug, was used in cases of abacterial prostato-vesiculitis. Thirty patients with a mean age of 33.7 years (range 18-58) were studied. Nimesulide was administered orally 100 mg b.i.d. for three cycles of 10 d each. Dysuric symptoms, semen analysis, and transrectal ultrasound were examined during the study. The concentration-time curves of nimesulide (NIM) and its metabolite, hydroxynimesulide (OH-NIM) in seminal fluid were also evaluated after single oral administration (100 mg) using an HPLC technique. Following administration of the drug, the Cmax was reached in seminal fluid at the second hour for NIM (with a mean value +/- SD of 0.58 +/- 0.13 micrograms ml-1) and at the fourth hour for OH-NIM (2.98 +/- 0.38 micrograms ml-1). Maximal seminal fluid concentrations compared to blood plasma levels were observed at the fourth hour for both substances (31.73 +/- 2.34% for NIM; 31.87 +/- 8.66% for OH-NIM. Dysuric symptoms were relieved in 20 (66%) patients. A clear amelioration of inflammatory signs were observed at transrectal ultrasound evaluation in 16 (54%) patients. No statistically significant changes of sperm count and motility in the whole sample were observed, while a significant reduction in the number of abnormal forms occurred. From these results, nimesulide appears to be an effective anti-inflammatory drug with a good diffusion into the genital apparatus and low side-effects.

Abstract
The efficacy and tolerability of nimesulide were assessed in the treatment of patients with prostato-vesiculitis. In a noncomparative investigation, 30 patients received oral nimesulide 100mg twice daily for three 10-day cycles. Micturition-related symptoms were resolved in 20 patients and clear amelioration of inflammatory signs was observed with transrectal ultrasound in 16 patients. Abnormal sperm forms decreased from 57 to 49% (p < 0.001). In a comparative investigation, 40 patients received nimesulide 200mg twice daily or ketoprofen 100mg twice daily via the rectal route. Patients and physicians expressed an overall opinion on efficacy in favour of nimesulide. In a pharmacokinetic study of healthy volunteers who received oral nimesulide 100mg as a single dose, the mean maximum nimesulide concentration (0.58 +/- 0.13 mg/L) in seminal fluid was achieved after 2 hours while the maximum seminal fluid: blood plasma ratio 0.32 +/- 0.02 was observed after 4 hours. These data suggest that nimesulide is an effective NSAID in the treatment of abacterial prostato-vesiculitis and also demonstrate that this drug has a favourable disposition within the genital tract.

Abstract
Male sexual impotence is the symptom of an alteration of central and peripheral mechanism neuropsychoendocrine, vascular and neurological. Nowadays it affects 8-10% of sexually active population. In some diseases, like diabetes and uremia, it can reach very high percentages of incidence. At our Andrology Center 35% of referrals are represented by sexual complaints. In the last years the diagnostic accuracy has increased, narrowing the percentage of unknown causes. Vasculopathy represents the most relevant pathological condition associated with impotence: it can affect both arterial and venous vessels. The new medical technologies and procedures permit an increase of the life span but often affecting the quality of life. Therefore, the iatrogenic causes of impotence, both pharmacological and surgical, are growing. A modern diagnostic approach starts with an accurate clinical history and physical examination, followed by an NPT (nocturnal penile tumescence) test and/or ICI (intracavernosal injection) with a standard dose of PGE1 and Doppler flowmetry of penile arteries. An endocrine evaluation (LH, testosterone and prolactin) is also performed. Further investigation of a vascular dysfunction is represented by more invasive procedures, like arteriography, cavernosography and cavernosometry. A suspect of neurological disease is confirmed by sacral evoked potentials. According to the findings of these examinations, a correct therapeutical approach can be applied in 100% of cases. An endocrine treatment is adequate only when a clear reduction of T plasma level or hyperprolactinemia are present. The treatment of other central disorders causing psychoneuroendocrine impotence is promising, but still under investigation. The intracavernosal injection of vasoactive drugs, apart from having revolutionized the diagnostic approach to the impotent patient, represents a clear standpoint in medical management of impotence, particularly in vascular and neurological diseases. The great advancement in the technology of penile prostheses has allowed the development of valuable and reliable tools to be used in selected cases.

Abstract
Male sexual activity is in all mammalian species, included man, androgen-dependent. The role of testosterone (T) starts already during intrauterine life. It continues thereafter, inducing the development of sexual secondary characteristics and libido. Therefore T has represented the "classical" treatment of male sexual dysfunctions. In the therapeutic routinary use T is employed ad ester, like cipionate, enanthate and other i.m., undecanoate per os. When a pituitary defect is present and the testicular receptors are functioning a treatment with HCG can be employed.

Abstract
The introduction of intracavernosal (i.c.) administration of vasoactive drugs has revolutionized diagnosis and treatment of sexual impotence. This procedure, though, carries some risks and undesired side-effects, such as fibrosis, priapism, hematomas, etc. Thus, at our Centre has been evaluated the possibility of a transdermal (TS), either active or passive, treatment of impotence. In a first trial, double blind crossover, 62 patients have been treated with yohimbine (YOH) as ointment. About 5 mg of the drug were applied at the balanopreputial sulcus, twice daily. In 10 patients YOH was also assayed by HPLC in the blood drawn from the corpora cavernosa after the application of the drug: a rapid adsorption of the drug was demonstrated and a peak value of 58 ng/ml at 25 min. Treatment with YOH was particularly satisfactory in patients with impotence of recent onset and mild degree, that is without major vascular alterations. The active TD drug administration was tested with papaverine delivered with cavernous bodies by a C.T.D.A.S. (Controlled Transdermal Drugs Administration System). Thin layer chromatography has shown the passage of about 10% of patients a relevant amelioration of erectile function was observed.
