Background Diagnosis and treatment of prostate cancer is associated with anxiety, fear, and depression in up to one-third of men. Yoga improves health-related quality of life (QoL) in patients with several types of cancer, but evidence of its efficacy in enhancing QoL is lacking in prostate cancer. Methods In this randomized controlled study, 29 men newly diagnosed with localized prostate cancer were randomized to yoga for 6 weeks (n = 14) or standard-of-care (n = 15) before radical prostatectomy. The primary outcome was self-reported QoL, assessed by the Expanded Prostate Index Composite (EPIC), Functional Assessment of Cancer Therapy-Prostate (FACT-P), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT–F), Functional Assessment of Cancer Therapy-General (FACT-G) at baseline, preoperatively, and 6 weeks postoperatively. Secondary outcomes were changes in immune cell status and cytokine levels with yoga. Results The greatest benefit of yoga on QoL was seen in EPIC-sexual (mean difference, 8.5 points), FACIT-F (6.3 points), FACT-Functional wellbeing (8.6 points), FACT-physical wellbeing (5.5 points), and FACT-Social wellbeing (14.6 points). The yoga group showed increased numbers of circulating CD4+ and CD8+ T-cells, more production of interferon-gamma by natural killer cells, and increased Fc receptor III expression in natural killer cells. The yoga group also showed decreased numbers of regulatory T-cells, myeloid-derived suppressor cells, indicating antitumor activity, and reduction in inflammatory cytokine levels (granulocyte colony-stimulating factor [0.55 (0.05–1.05), p = 0.03], monocyte chemoattractant protein [0.22 (0.01–0.43), p = 0.04], and FMS-like tyrosine kinase-3 ligand [0.91 (−0.01, 1.82), p = 0.053]. Conclusions Perioperative yoga exercise improved QoL, promoted an immune response, and attenuated inflammation in men with prostate cancer. Yoga is feasible in this setting and has benefits that require further investigation. Trial registration clinicaltrials.org (NCT02620033).

Penile length during puberty should be evaluated individually according to the current pubertal stage. Our study offers a reliable reference table of penile length for pubertal age group.

The aim of the study is to investigate whether there is an effect of adult circumcision on ejaculation parameters and to research the relationship between intravaginal ejaculation latency time (IELT) and premature ejaculation diagnostic tool (PEDT). Adults who underwent voluntary circumcision between September 2010 and November 2011 were enrolled in this prospective study. The IELT before and 3 months following circumcision was recorded. Also, PEDT was filled out before and 3 months after circumcision. During statistical evaluation, the comparison of situations before and after circumcision was made using IELT averages and PEDT total scores. Furthermore, the correlation between changes in IELT and PEDT has also been evaluated. A total of 30 volunteers (mean age 21.25±0.44) were enrolled in the study. The volunteers' mean and median IELT before were 104.36±66.21 and 88 (26-307) seconds, whereas mean and median IELT after circumcision were 123.56±54.44 and 107.5 (67-300) seconds, respectively. The increase after circumcision was statistically significant (P=0.001). The mean and median PEDT score were 4.26±2.91 and 3 (1-12) before, and 2.63±1.82 and 2 (0-7) after circumcision. Improvement was statistically significant (P<0.0001). No correlation could be found between ejaculation time and PEDT scores. Circumcision during adulthood does not adversely affect ejaculatory function; it may slightly improve. However, it could not be interpreted as a justification for circumcision in men with premature ejaculation (PE).
