J Christ Nurs 2020 Jul/Sep;37(3):E21-E26

Faith community nurses often counsel patients regarding illness management and are in a unique position to provide support to those facing multiple illnesses. When faced with multiple illnesses, men with urologic problems commonly do not mention them at routine exams, yet older patients might ask a trusted faith community nurse about urological concerns such as prostatitis.

Implications of prostate inflammation on male fertility.

Andrologia 2018 Dec;50(11):e13093

Departamento de Bioquímica Clínica, Facultad de Ciencias Químicas, Centro de Investigaciones en Bioquímica Clínica e Inmunología, CIBICI-CONICET, Universidad Nacional de Córdoba, Córdoba, Argentina.

The prostate is the seat of three major causes of morbidity: benign prostatic hyperplasia, prostate cancer and prostatitis, three conditions in which inflammation has been implicated. A state of inflammation of the prostate gland, originally incited by an infection, an autoimmune response, a neurogenic stimulus or another trigger may have consequences on prostate functionality. In fact, male fertility depends intrinsically on the content of prostatic fluid factors secreted by the prostatic epithelium. Read More
