“…The increase in testicular AMH expression can cause an elevation of apoptosis and a reduction in cell proliferation [30]. Regarding the seasonal breeders, a high expression level of AMH genes during the non-breeding season and a low expression level during the breeding season has been shown in male animals [34]. Similarly, a study on the quail testis demonstrated an upregulation of AMH when the testis was seasonally regressed [35].…”

The hipposideros larvatus (intermediate roundleaf bat) is one of the insectivorous bats which has an agro-ecological role as a controller of the insect population. The reproductive patterns of H. larvatus are intricately linked to its ecological role and survival. An understanding of the testicular morphology can contribute to conservation for this species particularly in areas where its populations might be declining or under threat. However, these bats may also be associated with zoonotic diseases which can have significant public health implications. The aims of the study were to examine the morphological data as well as the expression of the androgen receptor (AR) and anti-Müllerian hormone (AMH) in the male reproductive organs of H. larvatus from different areas of Thailand and at different sampling periods. Their testes were processed for histological investigation and immunohistochemistry for AR and AMH. The results showed differences among the various sampling areas and different sampling periods, which suggested seasonal breeding characteristics. The higher testicular morphometric data were observed in H. larvatus from the Dong Phayayen (DY) and Chiang Dao (CD) areas during June, while the size of seminiferous tubules decreased thereafter. High AR immunostaining was noticed when the testicular morphometric data were higher in DY bats during June. On the other hand, low AR was observed in bats during August and September, which was concomitant with the decreases in seminiferous tubule size and germinal epithelial height. The results suggest a potential correlation between AR immunostaining and the active phase of testicular functions in H. larvatus during June which may imply the involvement of AR with the enhancement of testicular activity. Conversely, the low expression of AR may contribute to the upregulation of AMH in the testes and may indicate lower testicular activity in H. larvatus in Thailand.

Reindeer husbandry is the leading branch of agriculture for the regions of the Far North. Reindeer (Rangifer tarandus) remains poorly studied from the point of view of genetics and reproduction, which hinders the intensification of development of the industry. Research is being actively conduct in the field of genetics of the productive qualities of reindeer, but the formation and functioning of its reproductive system has been little study. Hormonal regulation of the reproductive process and the formation of hormonal status at key stages of the reproductive cycle is a significant aspect of animal reproduction. Reindeer are characterized by a pronounced seasonality of reproduction, and the study of hormonal regulation of the reproductive cycle is the main aspect of the further use of assisted reproductive technologies. The work is devoted to the analysis of the level of anti-Mullerian hormone in females during the breeding season. The studies were carried out on reindeer farms of the MAU “Directorate of the Territory of Traditional Natural Resources Management of Soyots”, Buryatia, (female, n=29). The dependence of the concentration of anti-Müllerian hormone (AMH), which is a generally accepted indicator of the female ovarian reserve, on the concentration of sex hormones (progesterone, estradiol, testosterone and luteinizing hormone) in the blood serum of females was study. Hormone levels were determined by enzyme immunoassay. A higher content of sex hormones - testosterone, estradiol, progesterone and luteinizing hormone was revealed in the group of women with an AMH concentration of >1 ng/ml than in the group of women with an AMH concentration of <1 ng/ml. The significance of the differences in progesterone was p<0.05, and in estradiol – p<0.001. A low concentration of AMH (<1 ng/ml), characterizing a reduced ovarian reserve of female reindeer, corresponds to a reduced concentration of sex hormones that support reproductive function, and, conversely, a high concentration of AMH (>1 ng/ml), and, accordingly, a high ovarian reserve the reserve corresponds to an increased concentration of sex hormones - testosterone, estradiol, progesterone and luteinizing hormone.
