“…It also protected the intestinal mucosa and improved its absorptive capacity, preventing diarrhea by decreasing the peristastic movement of the intestine [ 35 ]. In contrast to our results, of Abdel-Wareth et al [ 16 ], Tag-El Din [ 24 ], and El-Kazaz et al [ 36 ] revealed that nano-Se reduced the TFI in growing NZW rabbits, male Californian rabbits, and Japanese quails, respectively. Such variations may be attributed to using different doses, sex, or species.…”

“…Supplementation with Se has been reported to improve the testicular characteristics and semen quality of Saanen bucks (37). Moreover, it was found that the use of nano-Se in the ration of Japanese quail improves several reproductive performance parameters (12). Furthermore, Se caused a significant improvement in sperm count and quality in varicocelized rats (61).…”

With the observed in the last years increasing disruption of poultry males’ fertility, there is a need to improve knowledge on the morphology and functioning of the avian reproductive system. A number of molecular and endocrine interrelationships indicate that testicular dysfunction may be one of the reasons for the production of poor semen quality. Because selenium (Se) is known to be an essential element for spermatogenesis, thus the aim of the present study was to determine the effect of Se treatment in ovo on cellular and molecular status (expression of aromatase, estrogen receptors and estrogen level) of testes of chicks. The study was performed on chick embryons exposed to Se at a dose of 0.6 µg/egg. We revealed diverse changes in testis histology after Se-treatment including developmental changes reflected by cell migration or vacuolization of the marginal stroma. We showed for the first time the expression of GPER in the testes of chicks and changes in the expression of aromatase, GPER, ERα and ERβ after treatment with Se. Simultaneously with these, decreased testicular estradiol concentration indicated an altered receptor protein and/or binding by Se only to GPER, ERα that in turn affects hormone concentration and action. Further studies are needed to evaluate other effects of Se supplementation especially of immature birds or mature ones and eggs laying by them per se.

“…Varlamova et al summarized the data of many researchers who described the positive physiological effect of nano-scale Se in the case of neurodegenerative disorders [ 79 ]. Nano-Se dietary supplementation improved the Se deposition in the testis and ovary of Japanese quail and their reproductive performance, thus prolonging their youth [ 137 ]. Se nanoparticles effectively prevented the progression of diabetic nephropathy [ 138 ].…”

Aging is characterized by an imbalance between damage inflicted by reactive oxygen species (ROS) and the antioxidative defenses of the organism. As a significant nutritional factor, the trace element selenium (Se) may remodel gradual and spontaneous physiological changes caused by oxidative stress, potentially leading to disease prevention and healthy aging. Se is involved in improving antioxidant defense, immune functions, and metabolic homeostasis. An inadequate Se status may reduce human life expectancy by accelerating the aging process or increasing vulnerability to various disorders, including immunity dysfunction, and cancer risk. This review highlights the available studies on the effective role of Se in aging mechanisms and shows the potential clinical implications related to its consumption. The main sources of organic Se and the advantages of its nanoformulations were also discussed.
