<br>👉 Many men successfully stay on testosterone therapy without noticeable hair loss—especially when proactive strategies are used. If you stop TRT, you’ll return to your normal level of testosterone. If you stop taking testosterone, your levels will return to baseline.

One may suggest contraceptive measures or fertility augmenting treatment as deemed appropriate. Though fertility is rarely an issue in this age group, the health-care professional should enquire about the person's needs and wishes. The man in andropause, who is usually in mid-life, will require more confidence building and support from the health-care professional. Transmen will require just 50%–75% of normal dosage to achieve masculinization and are more susceptible to side effects such as acne. This consideration is especially important while using testosterone undecanoate, which is injected as a 4 ml oily suspension.

The key hormone involved isn’t actually testosterone—it’s Dihydrotestosterone (DHT). Our Find a Provider tool makes it easy to search Cleveland Clinic’s trusted network. Your provider is there to support you in all aspects of your health. Testosterone replacement therapy may be an option for you. For all these reasons, your healthcare provider will carefully consider if TRT is safe for you based on your unique characteristics.

Laboratories that perform testosterone assays that have a CV that falls within ±6.4 % of samples tested by the CDC (with testosterone values ranging from 2.5-1,000 ng/dL) are certified. Part of this effort includes the availability of serum-based reference material from pooled sera available from the National Institute for Standards and Technology for testosterone and a hormone standardization program using liquid chromatography/mass spectrometry (LCMS) offered by CDC. The differences in testosterone methodologies have led to considerable effort by a variety of parties including the Centers for Disease Control (CDC) and the College of American Pathologists towards harmonization of assays. These parameters are calculated by analyzing normal and abnormal control specimens that have known values of the substance being measured. It is bound to albumin (50%, loosely-bound), sex hormone-binding globulin (SHBG, 44%, tightly-bound), corticotropin-binding globulin (4%, loosely-bound), and approximately 2% circulates as free testosterone.9 The free and loosely-bound testosterone fractions combined are known as bioavailable testosterone.Testosterone assays are plagued by variability in results. Early morning samples from each subject's most recent and previous 3 visits as well as those from 10, 15, 20, 25, and 30 years prior [www.thehispanicamerican.com](http://www.thehispanicamerican.com/companies/testosterone-levels-by-age-in-men-chart-how-to-test/) were analyzed (3,565 samples total with a mean of 4 samples per patient).

In addition to issues relating to the reliability of compounded products themselves, appropriate clinical studies on pharmacokinetics are lacking. Taylor et al. reported that clomiphene citrate has outstanding biochemical and clinical efficacy, with increases in serum [buy testosterone online](http://8.155.160.224:3000/jeraldandrews) similar to those for testosterone gel.400 Additionally, these investigators found that clomiphene has a favorable side effect profile and is less expensive than [buy testosterone gel online](https://tubex.su/@octavian35111?page=about) gel. Finally, hCG therapy alone or in combination with SERMs has been shown to facilitate recovery of testosterone production and spermatogenesis in men with a prior history of exogenous testosterone use333 or anabolic steroid abuse.334 Return of sperm to the ejaculate in these men can be highly variable, taking up to two years after cessation of exogenous testosterone in some cases, with some men never experiencing return of sperm.334 These agents share the common overall treatment effect of increasing intrinsic production of testosterone, but there are substantial differences in pharmacologic characteristics and mechanisms of action between them. More recently, a study evaluating the amount of residual testosterone identified on laundered clothing from men using an axilla-applied testosterone liquid reported the presence of 13% of a single axilla dose on 10x10 cm clothing samples.393 After laundering the clothing with various other materials, as much as 5.8% of a standard dose of one axilla was transferred to other garments. Normal sperm production depends on a functionally intact hypothalamic-pituitary-gonadal axis with normal secretion of pituitary LH and FSH to support intratesticular testosterone production and spermatogenesis.

Liquids and gels should be applied to clean, dry skin, and the treatment site should not be washed until the time of next application to optimize delivery. In analyzing the literature, it is imperative to determine whether or not statistically significant results are clinically meaningful. Beyond statistical significance, clinical relevance is another key factor.

If insufficient testosterone levels are achieved with one topical agent, including with dose adjustments, substitution with another topical agent is a viable treatment strategy.420 For example, a particular study might show that testosterone therapy is correlated with a statistically significant improvement in the IIEF scores in a given population; however, the clinician may not feel that this has any clinical meaning for the patient in terms of his QoL or sexual function. Differences in age, geography, date of initial testing (testosterone immunoassay testing was more commonly used before 2005), comorbid conditions, and baseline and therapeutic [buy testosterone injections](http://43.139.2.237:3000/walterl5448449) levels across studies introduce heterogeneity in the pooled population. As mentioned above, combination therapy with low dose hCG has been described as a means to maintain intratesticular testosterone levels394 and preserve spermatogenesis336 for men on exogenous testosterone. One study of 60 patients undergoing long-term therapy of 50 mg methyltestosterone three times a day found that nearly one-third of patients, none of whom had a history of liver disease, returned abnormal liver function tests and/or liver scans.387 Testosterone undecanoate is an oral testosterone analogue that is absorbed via the intestinal lymphatics allowing it to avoid the first pass liver effect.

Let’s break it down clearly so you (and your patients) can feel confident about treatment decisions. Together, you and your healthcare provider will weigh the risks and benefits of TRT to see if it could help. If symptoms of low testosterone are interfering with your quality of life, know that you don’t have to just grin and bear it.

Given these pharmacologic and mechanistic differences, combinations of these alternative therapies might, in some instances, be clinically appropriate. While SERMs, hCG, and AIs are all categorized as "alternative therapies" to testosterone, they are actually a diverse group of agents. For this reason, alternative therapies, including SERMs, AIs, and hCG, are commonly used to promote the endogenous production of testosterone. It is unclear if the transferred [buy testosterone online no prescription](http://218.201.98.56:18106/roxannesandber) remained biologically active. Populations at increased risk of adverse effects from transference include women and children, however very limited data are available on the true risks of transference with topical agents. Topical testosterone preparations (e.g., gels, creams, liquids) have the potential to result in transference to others. Given the availability of other approved [purchase testosterone](https://svideo.ge/@jessiejaques3?page=about) therapies, the use of 17-alpha-akylated androgens is not appropriate.
