End-stage renal disease is associated with disorders in hypothalamic-pituitary-gonadal function. Immunosuppressive therapies may influence the restoration of normal levels of gonadal hormones after renal transplantation. The aim of the present study was to evaluate the hormonal status of successful renal transplant recipients who were treated with different immunosuppressive agents. METHODS Testosterone, luteinizing hormone (LH), and follicle stimulating hormone (FSH) were measured in 59 male renal transplant recipients with stable graft function with serum creatinine <2.5 mg/dL. Patients were treated with three different immunosuppressive regimens: group I, calcineurin inhibitors (CI; n = 15), group II, sirolimus without calcineurin inhibitors (SRL; n = 15), group III, sirolimus in combination with calcineurin inhibitors (SRL * CI; n = 29). RESULTS Testosterone was significantly lower in group II versus group I (3.12 +/- 1.23 versus 4.39 +/- 1.53 ng/mL; P < .0197). Group III had higher testosterone values than group II, but lower than group I. FSH and LH were also higher in the SRL group, but the differences were not statistically significant, perhaps because of the small number of patients. No relationship was found between testosterone blood levels and age, posttransplant follow-up, renal function, time on dialysis, body mass index, steroid use, or posttransplant diabetes. CONCLUSIONS Sirolimus seems to impair the improvement of gonadal function after renal transplantation. Further prospective studies are needed to confirm these data before patients are advised of this potential side effect.

UI MeSH Term Description Entries
D007166 Immunosuppressive Agents Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.

D007986 Luteinizing Hormone A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.

D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

D005640 Follicle Stimulating Hormone A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Follicle-stimulating hormone stimulates GAMETOGENESIS and the supporting cells such as the ovarian GRANULOSA CELLS, the testicular SERTOLI CELLS, and LEYDIG CELLS. FSH consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.

D013739 Testosterone A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL. 17-beta-Hydroxy-4-Androsten-3-one,17-beta-Hydroxy-8 alpha-4-Androsten-3-one,8-Isotestosterone,AndroGel,Androderm,Andropatch,Androtop,Histerone,Sterotate,Sustanon,Testim,Testoderm,Testolin,Testopel,Testosterone Sulfate,17 beta Hydroxy 4 Androsten 3 one,17 beta Hydroxy 8 alpha 4 Androsten 3 one,8 Isotestosterone
