The spine is particularly vulnerable to these changes, as the vertebrae must support the weight of the body and endure the stresses of movement and posture. Osteopenia can lead to osteoporosis, a more severe condition in which bones become brittle and porous, dramatically increasing the risk of fractures. The hormone also helps regulate the absorption and retention of calcium, a key mineral for bone strength. This balance is critical for maintaining bone density and ensuring that bones, including those in the spine, remain strong and resistant to fractures. Testosterone stimulates osteoblast activity, which helps build new bone, and inhibits excessive osteoclast activity, preventing the rapid breakdown of bone.
Notably, prior research indicates that the preservation and/or restoration of KE strength is a key predictor of walking function in persons with motor-incomplete SCI (72), providing a rationale to assess gait parameters in future TRT studies conducted in the incomplete SCI population. Intramuscular TRT dose-dependently increases circulating testosterone and its bioactive metabolites—dihydrotestosterone and estradiol (63)—via localized tissue-specific actions of the 5α-reductase and aromatase enzymes (64), respectively. However, our RCT did not specifically enroll older men, as suggested in the IOM report (62), because low testosterone develops at earlier ages in response to SCI (12). In comparison, Gorgey et al. (35) provided low-dose transdermal TRT (2–6 mg/day; 14–42 mg/week) for 16 weeks to men whose baseline testosterone was within the eugonadal range on average (431 ± 215 ng/dL) and did not detect any change in circulating testosterone.
4 was devised using data from studies with TRT dosages ≤7.5 mg/day as shorter studies tended to use higher doses, which would have confounded the analyses. 2 was devised using data from studies with TRT dosages ≤7.5 mg/day as shorter studies tended to user higher doses, which would have confounded the analyses. 4 Value presented are % body fat not FM (kg), without the provision of body weight pre-post it is not possible to work out Δ in FM. This is because higher doses (10 mg/day) were primarily administered for a shorter period of time (3–6 months) and predominantly in the gel format (Table 1), which would have impacted the analysis. The duration of treatment and dosage ranged from 3–36 months and 2.5–10 mg/day, respectively. This scoping review identified 14 and 13 studies that reported the effect of TRT on LBM and FM, respectively. The second and third authors extracted descriptive and outcome data from the included studies, which were then fact-checked by the primary author.
The review authors appear to have presumed that blinding was used in several studies but the justification for this was not clear. Two reviewers independently selected studies, assessed validity and extracted the data, thereby reducing the potential for reviewer bias and errors. However, the search terms were not reported and only published studies were eligible; this raised the possibility of publication bias, as the authors acknowledged. The review addressed a clear question that was defined in terms of the participants, intervention, outcomes and study design. Subgroup analyses showed no significant interaction between treatment and use of glucocorticoids, testosterone level at baseline, age, duration of follow-up and losses to follow-up. Testosterone and transdermal testosterone for femoral neck BMD. The review authors stated that this explained the heterogeneity among studies evaluating lumbar spine BMD (no data were presented).
This leads to more stress on muscles, ligaments, and other spinal structures, which may increase ongoing back pain. But when testosterone levels drop, the bone-building process becomes less active. When testosterone levels are normal, bone remodeling stays well balanced. When testosterone levels drop, the bones can slowly weaken. Many people know that testosterone helps build muscle, but fewer realize how closely it is linked to bone strength. Testing hormone levels is usually done when a person has several other symptoms, such as fatigue, low libido, reduced muscle mass, or mood changes. In addition, low testosterone is sometimes linked with higher levels of inflammatory markers in the body.
Working with several healthcare professionals ensures that every part of the problem is examined and treated. But when TRT is combined with targeted spine care, exercise, and healthy habits, the results can be far better. For example, if someone has both low testosterone and a disc problem, treating only the hormone issue will not fully relieve symptoms.
In conclusion, testosterone therapy shows promise as a treatment for back pain, but it's important to understand both its benefits and risks. It is important to find a healthcare provider who is experienced with testosterone therapy. Starting testosterone therapy for back pain can be a detailed process.
