We assessed the effect of smoking and/or obesity on semen parameters and testosterone/oestradiol (T/E) ratio among sub-fertile men treated with sub-inguinal varicocelectomy. In this prospective, controlled, clinical study, 80 sub-fertile men with clinical varicocele who were subjected to sub-inguinal varicocelectomy were assigned into four equal groups (n = 20/each), group A: obese and smokers, group B: obese and nonsmokers, group C: smokers and nonobese and group D: nonsmokers and nonobese. Semen parameters, serum testosterone, oestradiol, follicle-stimulating hormone, luteinising hormone, prolactin and calculation of T/E ratio were assessed at baseline and 6 months post-varicocelectomy. The mean age ± SD of the study population was 26.1 ± 4.55. No statistical difference was detected among the study groups regarding age, residence, education, marital status and occupation (p > 0.05 for each). Post-operatively, significant improvements in semen parameters were detected in all groups. There was a significant difference between groups A and B versus C and D (obese versus nonobese groups) and between groups A and C versus B and D (smokers versus nonsmokers; p < 0.05 for each) regarding semen parameters, testosterone level and T/E ratio. Smoking and/or obesity negatively affect(s) the favourable outcome of varicocelectomy, specifically improvement of semen parameters and hormonal pattern in sub-fertile men with varicocele., (© 2021 Wiley-VCH GmbH.)

We assessed the change of homocysteine (Hcy), insulin-like growth factor one (IGF-Ι) and oestrogen (E2) levels in patients with erectile dysfunction (ED) associated with chronic hepatitis C virus (HCV) infection. Eighty-five male patients with chronic HCV and/or ED were enrolled in this study. Seventy-five men were assigned to three equal groups (n = 25/each); Group A: patients who had chronic HCV and ED. Group B: patients who had chronic HCV and had no ED complaint. Group C: patients who had ED with no chronic HCV. In addition to 10 control patients with no ED or chronic HCV (Group D). All patients were subjected to: detailed medical and sexual history, complete physical examination, laboratory assessment including measurement of serum Hcy, IGF-1 and E2. The means of international index of erectile function scores were 8 and 16 in groups A and C respectively. There were significant differences in Hcy, IGF-I and E2 among study groups (p < 0.05 for each). There were significant differences in Hcy between patients with Child B and Child C. A strong association between severity of ED and chronic HCV was demonstrated. There was statistically significant increase of Hcy and E2 levels and reduction in IGF-I level in patients with ED associated with chronic HCV infection., (© 2018 Blackwell Verlag GmbH.)

Traditionally, clinical conditions synonymous with the ageing male included cardiovascular disease (CVD), type 2 diabetes mellitus (DM) and sexual dysfunction, and were widely regarded as independent clinical entities. Over the last decade, interrelationship of clinical conditions has been convincingly demonstrated. Declining testosterone levels in the elderly, once regarded as an academic endocrinological question, appear to be central to the listed pathologies. It is now clear that erectile dysfunction is an expression of endothelial dysfunction. Testosterone deficiency is associated with an increased incidence of CVD and DM. The latter is often the sequel of the metabolic syndrome. Visceral obesity, a pivotal characteristic of the metabolic syndrome, suppresses the hypothalamic-pituitary-testicular axis leading to diminished testosterone production. Conversely, substantial androgen deficiency leads to signs and symptoms of metabolic syndrome. It is erroneous not to include testosterone measurements in the progress of the CVD, DM and erectile dysfunction. These conditions correlate strongly with testosterone deficiency., (© 2010 Blackwell Verlag GmbH.)
