The aim of this study was to evaluate the development of male and female neonatal gerbil prostate under normal conditions and exposed to bisphenol-A (BPA). Normal postnatal development of the female gerbil prostate occurs earlier than and is morphologically distinct from that occurring in males. In BPA-exposed PND8 gerbils, we have not observed evidence of alterations in the ductal branching in either gender. However, the exposure to BPA alters the immunolabeling pattern of AR, ERα, and PCNA. In males, the exposure to high dosages of BPA resulted in a decrease in the proliferative status of the developing ventral prostate. In females, both high and low dosages were sufficient to decrease the proliferation of paraurethral buds in the branching process by more than 50%. Therefore, the obtained data indicate that BPA promotes antiproliferative effects during the neonatal development of the gerbil prostate, with more sensitivity to this endocrine disruptor in females.

Background: Benign prostatic hyperplasia (BPH) is a disease linked to the hormonal imbalance that occurs during aging and over the last decades, complementary and alternative medicines have come on the scene as a treatment option for BPH, such as herbal medicines. Coconut oil has been shown to be capable of interfering in testosterone-induced BPH. However, until now there is no study of the effect of coconut oil during aging.

Exposure to pesticides, individually or in a mixture, in drinking water is one of the main sources of human contamination, which causes adverse effects on the reproductive system. Our study aimed to investigate, the effects of a 90-day exposure to low concentrations of glyphosate (GLY), atrazine (ATZ), and 2,4-dichlorophenoxyacetic acid (2,4-D), in commercial formulations, on morphological, molecular, and hormonal parameters of the ventral prostate of gerbils (Meriones unguiculatus). The animals were exposed via drinking water to individual concentrations of GLY: 700 μg/L, ATZ: 3 μg/L, and 2,4-D: 70 μg/L, as well as to their mixture (MIX).

Paradoxical sleep deprivation (PSD) presents different effects on metabolism and neurological functions. In addition, over long duration, sleep restriction (SR) can promote permanent changes. The prostate is an endocrine-dependent organ with homeostatic regulation directly related to hormone levels.

The prostate undergoes normal or pathological morphological changes throughout life. An understanding of these changes is fundamental for the comprehension of aging-related pathological processes such as benign prostatic hyperplasia (BPH) and cancer. In the present study, we show some of these morphological changes, as well as histochemical techniques like Weigert's resorcin-fuchsin method, Picrosirius Red, and Gömöri's reticulin for use as tools in the study of prostate tissue under light microscopy.

The female prostate, also known as Skene's gland, is present in both humans and rodents. Prenatal exposure to ethinylestradiol (EE2), a synthetic estrogen found in oral contraceptives, induces pormotes neoplasic prostate lesions in gerbils (). Conversely, pequi oil (Pe), extracted from the Brazilian Cerrado fruit, has antioxidant, anti-inflammatory, and anticancer properties, mitigates risks associated with chronic diseases related to lifestyle and aging.
