From: Bren on 5 Aug 2007 07:39 I will quote a brief compilation from another group, with permission. If anyone wishes to join in the 'nandrolone debate' I'd be most obliged if they would read the compliation FIRST - before they dive in ;-) Bren. " First line treatment of prostate cancer is often with the LHRH- agonist (or, gonadotropin super agonist: lupron, zoladex, trelstar.) or estrogens, to block the production of male androgen. Many doctors recommend a life time of treatment (or at least many years) with these drugs. However their primary effect of castration, with the main symptoms hypogonadism and feminisation being extremely problematic for many men: The experience of mental and physical decline under androgen deficiency is quite consistent with reports in the learned literature[1] describing the condition of hypogonadal men: sequelae include bone demineralisation[2], muscle wasting[3], penile shrinkage[4], early onset Alzheimer's disease[5], metabolic syndrome[6] and myocardial infarction[7] to name but a few. For anyone hooked into a chemical castration loop (or indeed anyone permanently castrated by chemical or physical procedures) , nandrolone looks particularly promising since it is as effective as costly alternatives for treatment of extreme debility[8]; yet it has virilising effects that may offset the distressing feminisation[8*] of LHRH-a and estrogens. Nandrolone is only mildy androgenic and is not associated with a worsening of prostate cancer markers[9]. Nandrolone induces suppression of the HPG axis[10] with testicular[11] and prostatic atrophy[12] that is consistent with the purpose of androgen suppression for the control of prostatic tumour. Most importantly, nandrolone does not cause mental or physical debility and other significant QoL issues mentioned above. The question also arises "Is nandrolone (Deca Durabolin) an untapped chemotherapy preventive for prostate cancer ?" 1: Int J Impot Res. 2006 May-Jun;18(3):223-8. Male hypogonadism. Part II: etiology, pathophysiology, and diagnosis. Seftel A. Department of Urology, Case Western Reserve University, Cleveland, OH 44106, USA. adsef...(a)aol.com Male hypogonadism has a multifactorial etiology that includes genetic conditions, anatomic abnormalities, infection, tumor, and injury. Defects in the hypothalamic-pituitary-gonadal axis may also result from type II diabetes mellitus and treatment with a range of medications. Circulating testosterone levels have been associated with sexual function, cognitive function, and body composition. Apart from reduced levels of testosterone, clinical hallmarks of hypogonadism include absence or regression of secondary sex characteristics, reduced fertility (oligospermia, azoospermia), anemia, muscle wasting, reduced bone mass (and bone mineral density), and/or abdominal adiposity. Some patients, particularly those with partial androgen deficiency of the aging male, also experience sexual dysfunction, reduced sense of vitality, depressedmood,increased irritability, difficulty concentrating, and/or hot flushesin certaincases of acute onset. As many patients with male hypogonadism - likepatients with erectile dysfunction - do not seek medical attention, it is important for clinicians to be acquainted with the signs and symptoms of hypogonadism, and to conduct appropriate laboratory testing and other assessments to determine the causes and inform the treatment of this condition.

Department of Medical Physiopathology, La Sapienza University, Rome, Italy. andrea.isid...(a)uniroma1.it Epidemiological studies correlated the age-related decline of serum testosterone levels to the concomitant increase of cardiovascular diseases, osteoporosis and bone fractures. For this reason, testosterone replacement therapy (TRT) in older men with late-onset hypogonadism has been advocated. Testosterone has an anti-resorptive effect that may increase bone density at lumbar spine. Androgens may also have cardio-protective effects by improving endothelial function and reducing the risk factors for atherosclerosis. It has been proposed thatatherosclerosis and osteoporosis share common pathophysiologicalmechanisms. Therole of inflammatory cells, citokynes and calcium deposition into thevascular walls has been reviewed to explore the causal nexus betweenthese frequently associated diseases. Experimental studies indicatethat a deregulation in the commitment of pluripotent mesenchimal stemcells toward specialized phenotypes might participate in thedevelopment of these conditions. The crossed-over beneficial effect ofbisphosphonate on the cardiovascular system and statins on bonemetabolism supports the research for a unitary pharmacologicalapproach to both conditions. The findings that androgens regulatemesenchimal celldifferentiation, as well as body composition, lipid profile and bonemetabolism, have claimed a role for TRT in aging men with late onset-hypogonadism.

Sublingual testosterone replacement improves muscle mass and strength, decreases bone resorption, and increases bone formation markers in hypogonadal men-a clinical research center study.

Department of Medicine, Harbor-University of California-Los Angeles Medical Center, Torrance 90509-2910, USA. W...(a)HARBOR6.HUMC.EDU To study the effects of androgen replacement therapy on muscle mass and strength and bone turnover markers in hypogonadal men, we administered sublingual testosterone (T) cyclodextrin (SLT; 5 mg, three times daily) to 67 hypogonadal men (baseline serum T, < 8.4 mol/ L) recruited from 4 centers in the U.S.: Torrance (n = 34), Durham (n = 12), New York (n = 9), and Salem (n = 12). Subjects who had received prior T therapy were withdrawn from injections for at least 6 weeks and from oral therapy for 4 weeks. Body composition, muscle strength, and serum and urinary bone turnover markers were measured before and after 6 months of SLT. We have shown previously that this regimen for 60 days will maintain adequate serum T levels and restore sexual function. Total body (P = 0.0104) and lean body mass (P = 0.007) increased with SLT treatment in the 34 subjects in whom body composition was assessed. There was no significant change in total body fat or percent fat. The increase in lean body mass was mainly in the legs; the right leg lean mass increased from 8.9 +/- 0.3 kg at 0 months to 9.2 +/- 0.3 kg at 6 months (P = 0.0008). This increase in leg lean mass wasassociated with increased leg muscle strength, assessed by leg press(0 months, 139.0 +/- 4.0 kg; 6 months, 147.7 +/- 4.2 kg; P = 0.0038).SLT replacement in hypogonadal men led to small, but significant,decreases in serum Ca (P = 0.0029) and the urinary calcium/creatinineratio (P = 0.0066), which were associated with increases in serum PTH(P = 0.0001). At baseline, the urinary type I collagen-cross linked N-telopeptides/creatinine ratio [75.6 +/- 7.9 nmol bone collagenequivalents (BCE/mmol] was twice the normal adult male mean (41.0 +/-3.6 nmol BCE/mmol) and was significantly decreased in response to SLTtreatment at 6 months (68.2 +/- 7.7 nmol BCE/mmol; P = 0.0304) withoutsignificant changes in urinary creatinine. Serum skeletal alkalinephosphatase did not change. In addition, SLT replacement causedsignificant increases in serum osteocalcin (P = 0.0001) and type Iprocollagen (P = 0.0012). Bone mineral density did not change during the 6 months of SLT treatment. We conclude that SLT replacement therapy resulted in increases in lean muscle mass and muscle strength. Like estrogen replacement in hypogonadal postmenopausal females, androgen replacement therapy led to decreased bone resorption and urinary calcium excretion. Moreover, androgen replacement therapy may have the additional benefit of increasing bone formation. A longer term study for several years duration would be necessary to demonstrate whether these changes in bone turnover marker levels will result in increased bone mineral density decreasedfracture risks, and reduced frailty in hypogonadal men.

Yassin AA, Saad F.Clinic of Urology/Andrology, Segeberger Kliniken, Norderstedt-Hamburg, Germany. yas...(a)t-online.de Recently, testosterone undecanoate (TU), a new parenteral testosterone (T) preparation has been introduced. Two of its distinctive features are (a) its prolonged action: after two initial loading injections 6 weeks apart, usually only one injection every 12 weeks is needed (b) over the full interval between two injections, plasma T levels are in the physiological range. New research presents convincing evidence that T has profound effects on tissues of the penisinvolved in the mechanism of erection and that testosterone deficiencyimpairs the anatomical and physiological substrate of erectilecapacity, which is, at least, in part reversible upon androgentherapy. Our studies with TU demonstrated that venous leakage could becorrected with T treatment in a number of patients. We further couldshow that sexual functions, in a substantial number of elderly men,can be restored with treatment with T only. So, these results arguefor determination of T levels in elderly men with sexual problems. Ifthe levels are subnormal, T treatment is warranted.

Hogervorst E, Combrinck M, Smith AD.Oxford Project To Investigate Memory and Ageing, Department of Pharmacology,University of Oxford, Oxford, UK. eva.hogervo...(a)pharm.ox.ac.uk OBJECTIVES: Sex steroids such as testosterone and estradiol might protect the brain against Alzheimer's disease (AD). We previously found lower levels of testosterone in men with AD compared with controls. We wanted to assess levels of pituitary gonadotropins that regulate sex steroid levels, to determine whether primary or secondary hypogonadism was responsible for low levels of testosterone in cases. METHOD: We included 45 men with AD (McKhann, 1987), 15 men with other types of dementia and 133 elderly controls from the Oxford Project to investigate Memory and Ageing. Gonadotropins (follicle stimulating hormone or FSH and luteinizing hormone or LH), sex hormone binding globulin (SHBG, which determines the amount of free testosterone) and testosterone were measured using enzyme immunoassays. RESULTS: We found no difference in average LH (8.7 +/- 9 UI/L), FSH (13 +/- 17 UI/ L) or SHBG (44 +/- 18 nmol/L) levels between AD cases and controls. Similar to our earlier findings, testosterone levels were significantly lower in men with AD (13 +/- 6 nmol/L) compared with controls (17 +/- 8, O.R. = 0.92, 95% C.I. = 0.87 to 0.97, p<0.005). Results were unchanged when controlled for age, SHBG and gonadotropin levels. CONCLUSION: Although normal, the levels of gonadotropins were inappropriately low for the levels of testosterone. Our results support a preliminary conclusion that secondary hypogonadism occurs in men with AD. This could be a consequence of brain degeneration. This is contrary to an earlier study (Bowen, 1999) that found raised levels of gonadotropins in cases with AD, suggesting primary hypogonadism. Our cohort was younger than theirs and gonadotropin levels increase with age. We are enlarging our data set to investigate whether primary hypogonadism occurs in older cases with AD or whether secondary hypogonadism precedes cognitive dysfunction in men at risk for AD. If this is true, testosterone replacement therapy for hypogonadal men at risk for dementia may be indicated. PMID: 14523358 6: Aging Male. 2007;10(2):53-56. Testosterone deficiency and the metabolic syndrome. Lunenfeld B Faculty Of Life Sciences. Faculty of Life Sciences, Bar-Ilan University. Ramat Gan. Israel. Evidence is presented to link components of the metabolic syndrome to testosterone deficiency and obesity. Testosterone deficiency in hypogonadism or testosterone deprivation in normo-gonadotropic men increases fat mass as well as fasting insulin levels. Testosterone supplementation (TS) in a dose dependent manner, increase lean body mass (LBM), reduces fat mass, body mass index (BMI) and waist hip ratio in both young and elderly hypogonadal men. A negative association between T and insulin resistance as well as impaired glucose intolerance has been demonstrated and in type 2 diabetic men TS improves metabolic parameters. TS improves most components of the metabolic syndrome and also reduces inflammatory cytokines. PMID: 17558968 7 : J Clin Oncol. 2007 Jun 10;25(17):2420-5. Influence of androgen suppression therapy for prostate cancer on the frequency and timing of fatal myocardial infarctions.

Departments of Radiation Oncology and Medicine, Cardiovascular Division, Brigham and Women's Hospital and Lank Center for Genitourinary Oncology, Dana-Farber Cancer Institute, Boston, MA 02215, USA. adam...(a)lroc.harvard.edu PURPOSE: We evaluated whether the timing of fatal myocardial infarction (MI) was influenced by the administration of androgen suppression therapy (AST). PATIENTS AND METHODS: The study cohort comprised 1,372 men who were enrolled onto three randomized trials between February 1995 and June 2001. In the three trials, the men were randomly assigned to receive radiation therapy with 0 versus 3 versus 6, 3 versus 8, or 0 versus 6 months of AST. Fine and Gray's regression was used to determine the clinical factors associated with the time to fatal MI, and estimates of time to fatal MI were calculated using a cumulative incidence method. When comparing the cumulative incidence estimates using Gray's k-sample P values, increased weight was ascribed to the earlier data because recovery of testosterone is expected for most men within 2 years after short-course AST. RESULTS: Men age 65 years or older who received 6 months of AST experienced shorter times to fatal MIs compared with men in this age group who did not receive AST (P = .017) and men younger than 65 years (P = .016). No significant difference (P = .97) was observed in the time to fatal MIs in men age 65 years or older who received 6 to 8 months of AST compared with 3 months of AST. CONCLUSION: The use of AST is associated with earlier onset of fatal MIs in men age 65 years or older who are treated for 6 months compared with men who are not treated with AST.

Teruel JL, Aguilera A, Marcen R, Navarro Antolin J, Garcia Otero G, Ortuno J.Department of Nephrology, Hospital Ramon y Cajal, Madrid, Spain. The high cost of recombinant human erythropoietin has led us to consider the existing indications for androgen treatment of anaemia in patients with chronicrenal failure. In the present work, we have tried to identify those patients on haemodialysis for whom androgens could constitute a therapeutic alternative. The evolution of haemoglobin concentration was analysed in 84 patients (67 males and17 females) treated with a cycle of nandrolone decanoate (200 mg per week given intramuscularly, for six months). In the total group of patients, haemoglobin rose from 69 g/L to 87 g/L (p < 0.01). The increment in haemoglobin was notrelated to sex, basal haemoglobin, primary renal disease, or dose of nandrolone decanoate corrected by body weight. However, we observed a relationship between this increment in haemoglobin and patient age. Haemoglobin increased by 8 g/L inpatients younger than 46 years (n = 29), by 18 g/L in patients aged between 46and 55 years (n = 28), and by 27 g/L in patients older than 55 years (n = 27) (p< 0.01 between groups). In the last group, haemoglobin concentration at the endof androgen treatment was 101 +/- 16 g/L. The haemoglobin level reached duringandrogen treatment was maintained for over a year after androgen withdrawal in55% of the responder patients. A reversible rise in the serum concentration of triglycerides was the main side-effect observed. Nandrolone decanoate therapywas not associated with hepatotoxicity or an increase in blood pressure. Voicechange and mild hirsutism were observed in most of the women receivingnandrolone decanoate, and these secondary effects constitute a real disadvantageto its use in females. [8* But not in males undergoing androgen suppression therapy* ] In conclusion, our results showed that androgens are a useful alternative in the treatment of anaemia in male haemodialysis patients older than 55 years. Furthermore, the response obtained was similar to that observed with erythropoietin, but at a lower cost. PMID: 8936631 9: Scand J Urol Nephrol. 1996 Apr;30(2):129-31. Effects of androgen therapy on prostatic markers in hemodialyzed patients. Teruel JL, Aguilera A, Avila C, Ortuno J. Department of Nephrology, Hospital Ramon y Cajal, Madrid, Spain. We have prospectively studied the evolution of serum levels of the prostatic-specific antigen and prostatic acid phosphatase in 14 male hemodialyzed patients, receiving a cycle of nandrolone decanoate (200 mg intramuscularly, once a week, for six months) as treatment for anemia. Androgen administration did not produce significant increases in serum concentrations of both tumor markers (basal: 0.9 +/- 0.5 and 0.7 +/- 0.3 ng/ml; at six months: 1.3 +/- 1.1 and 0.8 +/- 0.7 ng/ml respectively). Only one patient had a value of prostatic-specific antigen over the normal range: 4.2 ng/mol at the sixth month period, with a rapid decrease after the withdrawal of androgens. All the remaining values of both markers were within the normal range. In another six patients undergoing a prolonged treatment with androgens (between 9 to 24 months), the serum levels of prostatic specific antigen and prostatic acid phosphatase were within the normal range in all of them. Nandrolone decanoate administration does not induce increases in prostate tumor markers when it is used as treatment for anemia in hemodialyzed patients.

Different anabolic steroids can exercise different effects on the pituitary-gonadal axis in males. During a pilot study regarding the possible beneficial effect of the anabolic steroid nandrolone decanoate (ND) on bone metabolism in patients with rheumatoid arthritis additional endocrinological parameters were studies. A significant decrease was found in the serum levels of testosterone, androstenedione and FSH and the ratio of testosterone/oestradiol. There was a significant increase in the serum levels of oestrone. The levels of oestradiol, SHBG, LH and cortisol remained unchanged. An inhibitory effect of ND on testicular testosterone secretion is assumed. The decrease in androstenedione levels is explained by the diminished testosterone secretion. The rise in oestrone levels is explained by peripheral aromatizing of ND to oestrogens. The presented findings are in accordance with the hypothesis that sex steroids can act directly on the pituitary resulting in selective FSH and LH secretion. The possible role of the ratio testosterone /oestradiol in controlling gonadotrophin output is discussed. PMID: 6812344 [PubMed - indexed for MEDLINE] 11: APMIS. 2005 Feb;113(2):122-5. High doses of nandrolone decanoate reduce volume of testis and length of seminiferous tubules in rats. Noorafshan A, Karbalay-Doust S, Ardekani FM. Shiraz University of Medical Sciences, Shiraz, Iran. no...(a)sums.ac.ir Anabolic-androgenic steroid (AAS) compounds rank among the drugs most widely abused with the goal of improving athletic ability, appearance, or muscle mass. It has been shown that these compounds have adverse effects on human and animal physiology and sperm quality, but quantitative structural changes of the testis have received less attention. The present study was conducted to evaluate the effects of nandrolone decanoate, which is one of the AAS compounds, on testis weight and volume, diameter and length of seminiferous tubules in rats by unbiased stereological methods. Adult rats were divided into three groups. The first comprised control rats; the second and third groups received low and high doss of nandrolone decanoate for 14 weeks. The rats were then left untreated for 14 weeks. After removal of the testis, stereological study of these tissues showed that the mean volume of testis and length of the seminiferous tubules in the animals that received high doses of nandrolone decanoate were reduced approximately 32% (p<0.01) and approximately 31% (p<0.04), respectively, in comparison with the control group. It can be concluded that the high doses of nandrolone decanoate produce structural changes in the rat testis that remain 14 weeks after stopping injection of the drug.

Anatomy Department, School of Medicine, Shiraz University of Medical Sciences, Zand Avenue, Shiraz, Fars 71348-45794, Iran. rba...(a)sums.ac.ir It has been shown that nandrolone decanoate which is one of the anabolic-androgenic steroid compounds changes the testis structure and sperm quality but quantitative studies of the prostate have received less attention. Control rats received the peanut oil and experimental group received nandrolone decanoate for 14 weeks. Then the rats were left untreated for 14 weeks. After 14 weeks of withdrawal, the prostate was studied using stereological methods. The mean prostate weight decreased approximately 39% (p<0.009) in nandrolone decanoate treated rats. The mean total prostate volume, glands, epithelia, fluids and collagen bundles reduced approximately 30% (p<0.03), approximately 31% (p<0.03), approximately 41% (p<0.02), approximately 31% (p<0.05) and approximately 59.5% (p<0.02) in the experimental group. The mean total luminal surface of the glands and total length of the vessels decreased approximately 40% (p<0.02) and approximately 46% (p<0.009), respectively, in the nandrolone decanoate treated rats. The height of epithelium did show no difference. It can be concluded that nandrolone decanoate causes atrophic changes in the components of rat prostate. PMID: 16597504 Bren.
