AB  - BACKGROUND During the last decades, the abuse of anabolic androgenic steroids (AASs) has become popular among professional and recreational athletes. The abuse of AASs leads to decreased levels of sex hormones, but the available literature a gives very small pool of data regarding the effects of swimming alone or combined with AASs on testicle tissue. The aim of this study was to investigate the effects of four-week administration of nandrolone decanoate and swimming training alone or in combination on morphometric parameters, androgen receptor (AR) and redox state in testicle tissue. The study included Wistar albino male rats, 10 weeks old, classified into 4 groups: control (T-N-), nandrolone (T-N+), swimming training (T+N-) and swimming training with nandrolone (T+N+). The rats from nandrolone (N+) groups received nandrolone decanoate 20 mg/kg b.w.once per week. The rats from training (T+) groups, swam 1 h/day 5 days/week. The isolated testicles were measured, left testicles were routinely processed for histological analysis, while right testicles were homogenized and prepared for the analysis of the following oxidative stress biomarkers: index of lipid peroxidation (TBARS), nitrites, catalase, superoxide dismutase (SOD), and reduced glutathione (GSH). RESULTS Diameter, as well as cross-section area of seminiferous tubules were decreased by 10 % and 21 % (respectively) in the T-N+ group and by 15% and 41 % (respectively) in the T+N+ group compared to control. Interstitium of the testicles was decreased in all experimental groups. Reduction of immunoreactivity of AR in T-N+ group was 22 %, in T+N+ group was 9 % compared to control. TBARS levels were increased in T+N- and T+N+ groups. Nitrites were decreased in T+N+ group. Catalase activity was increased in all experimental groups. Swimming alone or combined with nandrolone decreased the level of GSH compared to control. SOD activity was decreased in T-N+ and T+N+ groups compared to control. CONCLUSIONS Nandrolone alone or combined with swimming decreased morphometric parameters and amount of AR in testicle tissue. Changes in the redox state indicate reproductive dysfunction. RéSUMé: CONTEXTE: Au cours des dernières décennies, l’abus de stéroïdes androgéniques anabolisants (SAA) est devenu populaire parmi les athlètes professionnels et récréatifs. L’abus des SAA conduit à une diminution des niveaux d’hormones sexuelles, mais la littérature sur les effets de la natation seule ou combinée avec des SAA sur les tissus testiculaires est encore très limité. Le but de cette étude était d’étudier les effets de l’administration de quatre semaines de décanoate de nandrolone et de l’entraînement à la natation seuls ou en combinaison sur les paramètres morphométriques, le récepteur aux androgènes (RA) et l’état redox dans le tissu testiculaire. L’étude a inclus des rats mâles Wistar albinos, âgés de 10 semaines, classés en 4 groupes: contrôle (T-N-), nandrolone (T-N+), entraînement à la natation (T+N-) et entraînement à la natation avec nandrolone (T+N+). Les rats des groupes nandrolone (N+) ont reçu du décanoate de nandrolone 20 mg/kg p.c. une fois par semaine. Les rats des groupes entraînement (T+) nageaient 1 h/jour 5 jours/semaine. Les testicules isolés ont été mesurés, les testicules gauches ont été systématiquement traités pour l’analyse histologique tandis que les testicules droits ont été homogénéisés et préparés pour l’analyse des biomarqueurs de stress oxydatif suivants: indice de peroxydation lipidique (TBARS), nitrites, catalase, superoxyde dismutase (SOD) et glutathion réduit (GSH). RéSULTATS: Le diamètre, ainsi que la section transversale des tubules séminifères ont été réduits de 10 % et 21 % (respectivement) dans le groupe T-N+ et de 15 % et 41 % (respectivement) dans le groupe T+N+ par rapport au groupe témoin. L’interstitium des testicules était diminué dans tous les groupes expérimentaux. La réduction de l’immunoréactivité de RA dans le groupe T-N+ était de 22 %, dans le groupe T+N+ était de 9 % par rapport au groupe témoin. Les niveaux de TBARS ont augmenté dans les groupes T+N- et T+N+. Les nitrites ont diminué dans le groupe T+N+. L’activité de la catalase a été augmentée dans tous les groupes expérimentaux. La natation seule ou combinée à la nandrolone a réduit le niveau de GSH par rapport au contrôle. L’activité de la SOD était diminuée dans les groupes T-N+ et T+N+ par rapport au contrôle. CONCLUSIONS: La nandrolone seule ou combinée à la natation a diminué les paramètres morphométriques et la quantité de RA dans le tissu testiculaire. Les changements de l’état redox indiquent un dysfonctionnement de la reproduction.

AB  - Estrogen signaling plays an important role in pituitary development and function. In sensitive rat or mice strains of both sexes, estrogen treatments promote lactotropic cell proliferation and induce the formation of pituitary adenomas (dominantly prolactin or growth-hormone-secreting ones). In male patients receiving estrogen, treatment does not necessarily result in pituitary hyperplasia, hyperprolactinemia or adenoma development. In this review, we comprehensively analyze the mechanisms of estrogen action upon their application in male animal models comparing it with available data in human subjects. Sex-specific molecular targets of estrogen action in lactotropic (PRL) cells are highlighted in the context of their proliferative and secretory activity. In addition, putative effects of estradiol on the cellular/tumor microenvironment and the contribution of postnatal pituitary progenitor/stem cells and transdifferentiation processes to prolactinoma development have been analyzed. Finally, estrogen-induced morphological and hormone-secreting changes in pituitary thyrotropic (TSH) and adrenocorticotropic (ACTH) cells are discussed, as well as the putative role of the thyroid and/or glucocorticoid hormones in prolactinoma development, based on the current scarce literature.

AB  - The aim of the study was to investigate the effects of chronic nandrolone decanoate treatment and/or swimming training on immunohistomorphometric parameters on rat pituitary gonadotropic cells. Male Wistar albino rats, 10 weeks old, were classified into four groups: control (T−N−), nandrolone (T−N+), swimming training (T+N−), and swimming training with nandrolone (T+N+). The T+ groups swam for 4 weeks, 1 h/day, 5 days/week. The N+ groups received nandrolone decanoate (20 mg/kg) once per week for 4 weeks. Pituitary tissue sections were processed and stained for immunohistochemical analysis and immunofluorescence. The volume density of luteinizing hormone (LH) cells was decreased by 48% in T−N+ and for 35% in the T+N+ group. The volume density of follicle-stimulating hormone (FSH) cells was decreased by 39% in T−N+ and for 30% in T+N+ compared to the control. Nandrolone alone, or combined with swimming training, decreased the number of LH/FSH cells compared to the control. The levels of the immunofluorescent signal of LH/FSH cells were increased in all experimental groups. Nandrolone alone decreased the serum level of LH by 17%, whereas swimming training alone increased FSH levels by 11% compared to the control. Serum levels of testosterone were increased in all experimental groups. Nandrolone alone, or combined with swimming training, decreased immunohistomorphometric parameters of gonadotropic cells, whereas the levels of immunofluorescent signal were increased.
