Testosterone is an important factor in a man’s sex drive and performance, but it is not the only fuel that rules that domain. Erectile dysfunction and lack of sex drive are sexual issues that may be a result of low testosterone. It is normal for a man’s sex drive to decline with age, but libido varies widely between men. Low Testosterone is not known to cause these conditions but rather the association between other medical conditions is significant.

Testosterone deficiency syndrome (TDS) is a clinical and biochemical syndrome frequently associated with age and co-morbidities and is characterized by deficiency in testosterone and relevant androgen-deficiency symptoms. Significant progress has been made in the field of medicine for erectile dysfunction (ED) since 1970s. Testosterone is vital for normal functioning throughout a mana€™s life and a reduced testosterone level could compromise the mana€™s general well-being and his sexual function.
Apart from penile erection, testosterone also regulates other aspects of male sexual desire. There is strong evidence that ED is an independent marker for subsequent cardiovascular disease and that the incidence of ED is more common in older patients with higher cardiovascular risks. The clinical presentation of TDS, defined as both low testosterone level and clinically significant symptoms, can be at times nonspecific and often overlooked or under-diagnosed. Patients with ED, together with other symptoms such as reduced libido, decreased muscle mass and strength, presence of type 2 diabetes mellitus and metabolic syndrome should be screened for TDS (Figure 1). Physical examination should focus on cognition, neurological, cardiovascular and urological findings. Laboratory diagnosis of testosterone deficiency: The exact pathogenesis of low testosterone remains contentious and several proposed mechanisms include decreased Leydig cell function, age-related increased in sex hormone binding globulin (which binds testosterone and lowers free bioavailable testosterone level), blunted circadian steady state of testosterone and decreased luteinizing hormone (LH) pulse by the hypothalamus [12]. The biochemical diagnosis of TDS is based on the measurement of serum total testosterone (TT), preferably before 11 am, though the diurnal rhythm of testosterone is less marked in men aged over 40 years.
While theoretically serum FT is more representative of the biological activity of testosterone, these assays may be more difficult to carry out (especially equilibrium dialysis, the reference method for FT), inaccurate (FT assay by testosterone analogue and a€?Free Androgen Indexa€™), or can only be performed by some laboratories. In the case of low or borderline testosterone value, the assay should be repeated, because of the frequent intra-individual fluctuations of serum testosterone, unless physical evidence of hypogonadism (i.e.
When choosing which TRT to prescribe, primary care physician must exercises good clinical judgment together with adequate knowledge of the advantages and drawbacks of TRT and considers the bioavailability, safety, tolerability, efficacy and preference of each TRT product (Table 1). The effects of TRT may be perceived within 2-4 weeks, but sexual effects may sometimes take 3-6 months to become apparent and even up to 1 year for the nocturnal erections to reach normal range in previously untreated hypogonadal patients [16]. Since the occurrence of any adverse events during therapy (such as an elevated hematocrit or PSA) requires rapid discontinuation of TRT, short-acting preparation is preferred over long-acting depot preparation in the initial treatment of hypogonadal men, but there is no contraindication to start with longer acting preparations. Testosterone & PDE5 Inhibitors in ED: As previously mentioned, testosterone modulates the expression of isoforms of nitric oxide synthase and PDE5 enzyme [19]. At present controversies exist whether men with hypoandrogenism and ED should be treated initially with PDE5 inhibitors, TRT or in combination [16]. Having never suffered erectile dysfunction, I can only imagine how devastating it must be to sufferers. Low free testosterone, erectile dysfunction and the rigidity of the erection in 1706 men. Erectile issues are sometimes caused by other medical issues such as atherosclerosis, the hardening of the arteries.
The main physiological action of testosterone in male sexual function is in sexual desire by regulating the timing of the penile erectile with sex. In the past, male sexual dysfunction was thought to be purely psychogenic but increased understanding in the erectile physiology at molecular level has shown that testosterone deficiency plays a major role in sexual dysfunction. Published literature showed that testosterone controls, directly or indirectly, several mechanisms pertinent to penile erectile function such as the promotion and differentiation of penile stem cells to penile smooth muscle cell phenotype, activity of cavernosal nitric oxide synthase and that of RhoA-kinase pathway [1]. While erections are possible in hypogonadal conditions, studies showed that patients with decreasing levels of sexual desire have progressively lower concentrations of testosterone than men who maintain their sexual desire. The clinical symptoms associated with TDS can be divided into 3 main groups, namely psychosomatic, metabolic and sexual related problems. The initial assessment of subjects with clinical suspicion of TDS should include a comprehensive evaluation of medical and psychosocial, associated co-morbidities as well as identification of any reversible factors and conditions that could impact on the prescription of testosterone replacement therapy (TRT) such as in subjects with undiagnosed prostate cancer, obstructive sleep apnea and congestive heart failure (Figure 1).

In men over the age of 40 years, prior to TRT, the risk of prostate cancer must be assessed and if the digital rectal examination of the prostate gland or prostate specific antigen (PSA) reading is abnormal, further urological assessment should be arranged [10]. Transient decrease in serum testosterone level such as in acute physical illness should be excluded by careful evaluation and repeat testosterone measurement. Furthermore there are no accepted lower limits of free testosterone for the diagnosis of TDS [10]. Hypogonadal men restored to eugonadal state with TRT will experience improvement in sexual functions, particularly erectile, ejaculation, orgasm and penile sensations; and restored or enhanced responsiveness to PDE5 inhibitors [10].
At present the use of gonadotophic hormones such as human chorionic gonadotropin and selective estrogen receptor modulator (such as clomifene citrate) is not recommended except in selected cases of male infertility [18]. Several studies have demonstrated that TDS is associated with a reduced PDE5 inhibitors efficacy [19].

An older friend did suffer from it, and it was a direct result of prostate cancer surgery, but in the process of dealing with that over a twelve month period, he taught me a lot about the subject and that most men who suffer from it do so because of low testosterone levels. The only natural and effective cure for erectile dysfunction is to increase the blood flow into the penis to induce an erection that stays erect long enough for satisfying sexual intercourse. In addition, many patients with low testosterone levels may complain only of loss of libido. Sex drive is also affected by stress, lack of sleep, depression and the opportunities for sexual engagement. Low testosterone symptoms do not always include a low sex drive. When damaged, the blood vessels that supply the penis cannot dilate and create a strong enough flow needed for a firm erection. However sexual dysfunction associated with TDS also includes erectile dysfunction (ED) and delayed ejaculation.
Men with low testosterone levels may often be overlooked as the association between testosterone deficiency syndrome (TDS) and its related co-morbidities such as cardiovascular disease and metabolic syndrome is not appreciated and at times, the symptoms and signs of TDS may not be obvious. More importantly, testosterone also regulates the expression of phosphodiesterase type 5 (PDE5), and in so doing maintains a homeostatic ratio between isoforms of nitric oxide synthase and PDE5 enzyme that is responsible for penile erection [2]. The association between ED, low testosterone level and cardiovascular disease are well recognized and these disorders are associated with the presence of metabolic syndrome [9]. Unfortunately none of the symptoms is specific to the low androgen state but each symptom may raise the suspicion of TDS.
While standardized questionnaires such as the Androgen Deficiency in Aging Male (ADAM) checklist is designed to identify symptoms and signs of TDS [10], they are not very specific but may play a role in encouraging men to discuss their symptoms and for monitoring changes in symptoms. The recommended tests for men with ED are fasting glucose, cholesterol, lipids and testosterone level.

The FT assays are generally set aside for the repeat assay and to certify the significance of a borderline TT level, or when SHBG concentration may be altered.
The magnitude of the effect on erectile function is inversely related to baseline concentration of testosterone. This underlies the important concept that TDS must be ruled out, or if present, should be adequately treated, before PDE5 inhbitors are prescribed in men with ED. Furthermore, some studies have suggested that erectile response may actually decreased when higher levels of testosterone were reached in men who were not hypogonadal [21].
Although hypoandrogenism can be the main cause of ED in younger patients, ED is often multi-factorial in pathophysiology and therefore it is unlikely that TDS is the sole contributor for the development and progression of ED. Is there an ideal diet for men concerned about preventing, improving or even reversing erectile dysfunction. Herbal sex capsules naturally improve blood flow into the penis resulting in a firmer, fuller, and longer erection that stays erect. High blood pressure, high cholesterol and diabetes are the three main causes of atherosclerosis and erectile dysfunction. The link between ED, testosterone deficiency and cardiovascular disorders is well documented.
This review article aims to provide primary care practitioners a practical approach to the diagnosis and management of testosterone deficiency in patients with ED. It appears that testosterone is responsible in the regulation of the timing of the erectile process as a function of sexual desire, thereby coordinating erection with sex [4]. In fact a clear negative relationship exists between the presence of the risk factors for metabolic syndrome and levels of circulating testosterone in patients with ED [9]. Previously, a brief (12 items) structured interview called the ANDROTEST has been designed specifically to screen for hypogonadism in patients with sexual dysfunction [11]. As a general rule of thumb, the mean serum total testosterone decreases by 1% per year after the age of 40 years [13]. The indication to start TRT must be based on complete clinical assessment with an evidence of hypoandrogenism. Men with severe lower urinary tract symptoms, polycythaemia (hematocrit >50%), untreated obstructive sleep apnoea, severe congestive cardiac failure, breast or prostate cancer should not be started on TRT without appropriate assessment and treatment by the respective specialists. Patients should be monitored at 3 months initially, and later at 3 to 6 monthly follow-up for adjustment of TRT and surveillance for any complication. Published literature showed the combination of TRT and PDE5 inhibitors enhances the overall efficacy in men with were previously PDE5 inhibitors unresponsive [19].
Hence, further studies are needed to evaluate the benefits of combination TRT and PDE5 inhibitors.
For this reason, combination therapy using TRT and PDE5 inhibitors should be considered as first line in the majority of cases as it might improve the clinical outcome better than TRT only.
The recommended tests for men with ED include fasting glucose, cholesterol, lipids and testosterone level. Some studies showed that higher androgen level potentially play a dominant role in increased frequency of autoeroticism behaviors [5] and propensity for extramarital affairs [6].
The use of TRT in clinically symptomatic hypoandrogenism men treated previously for localized prostate cancer remains controversial [15]. Longer duration of combination TRT and PDE5 inhibitors use appeares to increase the patient response rate to PDE5 inhibitors [20]. In studies, one in every three males that mentioned ED to their doctor ended up having low testosterone. Recent studies have also highlighted the role of testosterone in ejaculatory dysfunction via the effect of testosterone on nitric oxide metabolism in the central and peripheral control of ejaculation that could be accountable in condition such as premature ejaculation [7]. The selection of the TRT preparation should be a joint decision between an informed patient and his physician. A range of testosterone preparations are available for supplementation, and the combination of testosterone replacement therapy and phosphodiesterase type 5 inhibitors might improve outcomes in some cases. It is important to counsel younger men who wish to father children that exogenous TRT paradoxically results in infertility and this could potentially be irreversible.
The selection of the testosterone replacement therapy should be a joint decision between an informed patient and his primary care physician, and regular follow-up should be conducted to assess treatment efficacy and surveillance for adverse events.
