Lower serum total testosterone is associated with lymph node metastases in a radical prostatectomy cohort study.

Background: Data on testosterone levels of patients with prostate cancer of different grade and stage are inconsistent. We retrospectively investigated serum total testosterone of a radical prostatectomy cohort to further shed light on this problem.

Patients And Methods: The preoperative level of serum total testosterone of 217 patients (mean age: 65±5.

Are there symptom-specific testosterone thresholds in aging men?

Objective: • To study the association between specific clinical symptoms (e.g. low libido and erectile dysfunction) and testosterone levels and age in order to define symptom-specific testosterone thresholds.

Immunohistochemical expression analysis of Cx43, Cx26, c-KIT and PlAP in contralateral testis biopsies of patients with non-seminomatous testicular germ cell tumor.

Non seminomatous testicular germ cell tumors (NSTGCTs) express fetal stem cell markers and display dysregulation of connexin 43 expression. Persistence of fetal spermatogonial characteristics was implicated in the emergence of testicular germ cell tumors. The objective of this study was to analyze the tubular architecture in contralateral testes of patients with NSTGCT.

PSA testing in Austria: induced morbidity and saved mortality.

Opportunistic screening of healthy men by prostate-specific antigen (PSA) testing led to a steep increase of prostate cancer incidence in Austria. The objective of this study was to quantify how many additional men are diagnosed with prostate cancer by PSA testing, to save one man from prostate cancer death. Regression models for incidence and mortality for the time periods 1983-1991 and 1992-2003 by age groups 50-59 and 60-69 years were estimated.

How much physical activity is needed to maintain erectile function? Results of the Androx Vienna Municipality Study.

Objective: To assess the correlation of erectile function (EF) and physical activity (PhA) by using standardized, validated instruments in healthy men.

Methods: A urologist examined 674 men aged 45-60 yr at their place of work. That included a urological physical examination, medical history, and assessment of testosterone (T) and sex hormone-binding globulin; all men completed the 5-item International Index of Erectile Function (IIEF-5) as well as the Paffenbarger score.

Mood changes, body mass index and bioavailable testosterone in healthy men: results of the Androx Vienna Municipality Study.

Objective: To determine whether sex hormones alone or in combination with body mass index (BMI) influence mood in men.

Subjects And Methods: Blood samples were taken from 669 manual workers (aged 43-67 years) to measure sex hormone levels, in particular bioavailable testosterone (BAT). At the same time BMI was calculated.

The impact of age, body mass index and testosterone on erectile dysfunction.

Purpose: Erectile dysfunction (ED) may be associated with low serum total testosterone (T), low serum bioavailable testosterone (BAT) and high body mass index (BMI) in aging men.

Materials And Methods: A total of 675 workers (age range 45 to 60 years old) were entered into this study. Investigations were performed directly at their place of work.
