ABSTRACT Objectives: To study the impact of obesity, age and varicocele on sexual hormones fof adult and elderly men. Materials and Methods: 875 men who were screened for prostate cancer were enrolled in this study. Data recorded comprised age, body mass index (BMI), serum levels of total testosterone (TT), free testosterone (FT), sex hormone-binding globulin (SHBG), luteinizing hormone (LH) and follicular stimulating hormone (FSH). Patients were divided in groups according to their BMI in underweight, normal weight, overweight and obese grades 1, 2 or 3. First, it was studied the association between age, BMI, and hormone profile. Then, clinical varicocele was evaluated in 298 patients to assess its correlation to the others parameters. Results: Obese patients had lower levels of TT, FT and SHBG (p<0.001) compared to underweight or normal weight patients. There were no differences in age (p=0.113), FSH serum levels (p=0.863) and LH serum levels (p=0.218) between obese and non-obese patients. Obese grade 3 had lower levels of TT and FT compared to obese grade 1 and 2 (p<0.05). There was no difference in the SHBG levels (p=0.120) among obese patients. There was no association between varicocele and BMI; and varicocele did not impact on testosterone or SHBG levels. Conclusions: Men with higher BMI have a lower serum level of TT, FT and SHBG. The presence of clinical varicocele as well as its grade has no impact on hormone profile in elderly men.

The objective of the present study was to identify sperm abnormalities in young male patients with juvenile dermatomyositis (JDM). In 2005, 18 male JDM patients, diagnosed according to the criteria of Bohan and Peter, were followed at the Pediatric Rheumatology Unit and Rheumatology Division, of our Institution. Of the 18 males, 11 were pre-pubertal and 7 were post-pubertal. Two of 7 post-pubertal JDM male patients were excluded: one for orchidopexy for cryptorchidism and the other for testicular ectopia in the left testis. The remaining 5 post-pubertal JDM patients were prospectively evaluated on the basis of two semen analyses, according to the World Health Organization (WHO), urologic evaluation, testicular Doppler ultrasound hormone profile. The data of the JDM patients were compared with those of 5 age-matched healthy controls. The median age 18, was similar in JDM patients and controls. All JDM patients had teratozoospermia (abnormal sperm morphology), as did 4 (80%) of the controls. One of JDM patients had previous oligoasthenoteratozoospermia treated with intravenous cyclophosphamide with normalization of the number and concentration of the sperm after 5 years. All sperm parameters (sperm concentration, total sperm count and total motile sperm count by WHO, and sperm morphology by Kruger strict criteria), testicular volumes by Prader orchidometer and ultrasound, and hormones were similar in JDM patients compared with controls. The frequency of anti-sperm antibodies was similar in both groups. All JDM patients had minor sperm abnormalities in the head, midpiece, and/or tail of spermatozoids. Serial semen analyses in larger study populations are necessary to identify the extent and duration of sperm abnormalities in male patients with idiopathic inflammatory myopathies.
