The Translational Role of Animal Models for Estrogen-Related Functional Bladder Outlet Obstruction and Prostatic Inflammation.

Vet Sci 2022 Jan 31;9(2). Epub 2022 Jan 31.

Institute of Biomedicine, University of Turku, FI-20014 Turku, Finland.

The prevalence of LUTS and prostatic diseases increases with age both in humans and companion animals, suggesting that a common underlying cause of these conditions may be age-associated alterations in the balance of sex hormones. The symptoms are present with different and variable micturition dysfunctions and can be assigned to different clinical conditions including bladder outlet obstruction (BOO). LUTS may also be linked to chronic non-bacterial prostatitis/chronic pelvic pain syndrome (CP/CPPS), but the relationship between these conditions is unknown. Read More

Environmental Chemical Pollution and Health Research Unit, Faculty of Health Sciences, School of Health Systems and Public Health, University of Pretoria, Pretoria, South Africa; Environmental Chemical Pollution and Health Research Unit, Faculty of Health Sciences, School of Medicine, Department of Urology, University of Pretoria, Pretoria, South Africa.

Male sex determination and sexual differentiation occur between 6-12 weeks of gestation. During the "male programming window" the fetal testes start to produce testosterone that initiates the development of the male reproductive tract. Exposure to endocrine disrupting chemicals (EDCs) able to mimic or disrupt steroid hormone actions may disrupt testicular development and adversely impact reproductive health at birth, during puberty and adulthood.
