Androgen receptor (AR) immunohistochemistry was performed in an archival collection of adult human cryptorchid testes to determine whether AR cellular distribution and intensity of immunostaining were functions of the severity of cellular dysgenesis. The seminiferous tubule histology of cryptorchid testes collected from adults is marked by three specific patterns. 1) Seminiferous tubules are characterized as maintaining focal areas of germinal cell differentiation (albeit incomplete) that are interspersed with 2) tubules composed of Sertoli cells only, these latter cells being principally of the adult type, although dysgenetic and immature Sertoli cells may also be detected. 3) In contrast, there is a class of tubule that is characterized as being composed exclusively of Sertoli cells that are extremely dysgenetic in appearance. The majority of adult-type Sertoli cells found in the first types of tubules exhibited either robust or moderate AR staining intensity. Peritubular cells of these tubules also expressed a similar AR staining intensity. In contrast, in the more dysgenetic and immature type Sertoli cells found in the second type of tubules, the intensity of AR staining was significantly less, if not missing altogether. Finally, in the most dysgenetic tubules, Sertoli cell AR staining was never detected. To our knowledge, this is the first report in the literature that addresses the intensity of AR immunostaining in Sertoli cells of cryptorchid testes. The results presented herein are consistent with the interpretation that the intensity of AR staining in Sertoli cells diminishes as a function of the severity to which the cells are afflicted within a cryptorchid testis and that focal absence of AR expression in Sertoli cells correlates with a lack of local spermatogenesis in the tubules.

Abstract Anti-Mullerian hormone (AMH) and androgenic steroids are key factors regulating the masculinisation of the internal and external genitalia during fetal development. AMH is produced in Sertoli cells and causes regression of the Mullerian ducts in the male. 3β-Hydroxysteroid dehydrogenase (3β-HSD) is one of the key steroidogenic enzymes regulating testosterone production in Leydig cells. The objective of this experiment was to elucidate the development of the ovine fetal testes by identifying the spatio-temporal expression of AMH, 3β-HSD and androgen receptor expression within them. Fetuses from days 30 and 40 of gestation were fixed intact, while the gonads were dissected from the fetuses on days 70, 100 and 130 of gestation. Tissue was fixed in Bouin's fixative for 6 h, processed into paraffin wax and sections immunostained using rabbit anti-human AMH, 3β-HSD or androgen receptor antibodies. While seminiferous cords were absent on day 30 of gestation, pre-cord organisation was apparent and the gonad could be clearly distinguished from surrounding tissue by the presence of AMH and 3β-HSD immunopositive cells. Androgen receptor expression was not apparent at this stage. By day 40 of gestation the testis was organised into distinct seminiferous cords and intense immunostaining for AMH and 3β-HSD was present in Sertoli cells within the cords and Leydig cells in the interstitium respectively. Androgen receptor immunopositive cells were present in the interstitium but cells destined to develop into rete testis were immunonegative. By day 70 of gestation, the rete testis was organised in the centre of the testis and was strongly androgen receptor immunopositive. AMH and 3β-HSD expression was present in Sertoli and Leydig cells respectively. The expression of AMH, 3β-HSD and androgen receptor in the 100 and 130 day gestation fetuses was similar to that identified in the 70 day fetuses. In conclusion, Sertoli and Leydig precursor cells are present in the gonad prior to seminiferous cord formation and contain AMH and 3β-HSD at all stages of gestation examined. While androgen receptor immunoexpression was present in nuclei of interstitial cells from day 40 of gestation and in the rete testis from day 70 of gestation, Sertoli cells were immunonegative for androgen receptor at all of the stages examined.

Background: Ethanol extract of young papaya seeds (Carica papaya L.) contains steroids that thought to has the antifertility property. This study aims to prove this hypothesis by measuring the low levels of testosterone hormone, spermatozoa count, and androgen receptor expression in sertoli cells. Material and Method:We use the randomized post-test only control group design on thirty-six male Balb/c strain adult male mice aged 12-14 weeks, weight 20-25 grams. They were randomly divided into a control and treatment group. The treatment group was given the same food as the control group plus ethanol extract of young papaya seeds 20 mg/20 gram body weight as much as 0.5 ml, orally every day for thirty-six days. Data were analyzed using the independent-sample T-test and Mann Whitney test. Result:The levels in the treatment group were significantly (p<0.05) lower than those in the control. Testosterone levels 31,64±1,91 vs 48,67±1,81 nmol/L, spermatozoa count 42,72±3,33 vs 75,89±4,71 cell/field of view, and androgen receptor expression 28,11±3.06% vs 55.07±2.49%. Conclusion:The ethanol extract of young papaya seeds 20 mg/20 g body weight has the antifertility property.
