Sarcopenia is a physical condition that primarily affects older men, but it can also present at earlier stages due to factors such as a sedentary lifestyle, poor diet, and chronic illness. This progressive loss of muscle mass and strength not only impacts mobility and independence but can also affect quality of life and overall health.
In this article you will find an updated guide for this year, in which we will explore what sarcopenia is, what its causes are, how to diagnose it, its impact on male sexuality and the best treatment and prevention strategies based on scientific evidence.

What is sarcopenia?
Sarcopenia is a syndrome characterized by the progressive loss of muscle mass, strength, and function, primarily associated with aging. However, it can also occur in younger people due to factors such as a sedentary lifestyle, chronic illness, or malnutrition.
It is classified as a loss of muscle mass, which is measured by densitometry or bioimpedance, a decrease in muscle strength, and a reduction in obvious physical performance.
This condition increases the risk of falls, fractures, dependency, and mortality, so early diagnosis and treatment are essential.
Types or degrees
Primary (age-related) sarcopenia
This type of sarcopenia occurs as part of the natural aging process. Starting at age 30, men begin to lose approximately 1 to 2% of their muscle mass per year, a process that accelerates significantly after age 60. The main mechanisms include reduced muscle protein synthesis, decreased anabolic hormone production, and the accumulation of oxidative damage in muscle fibers.
Secondary sarcopenia
In this case, muscle loss is not only due to aging, but also to external factors such as chronic diseases, such as diabetes, cancer, chronic obstructive pulmonary disease (COPD), heart failure, or rheumatoid arthritis. It can also be caused by malnutrition or poor nutrient absorption, or by prolonged inactivity.
Severe or advanced sarcopenia
This is diagnosed when there is extreme loss of muscle mass (confirmed by DEXA or MRI), when muscle strength is severely reduced, with a grip dynamometry test showing less than 20 kg, or when there is severe functional impairment, such as the inability to rise from a chair without assistance or walk without support.
This degree significantly increases the risk of dependency, fractures and mortality.
Why do men lose muscle mass?
Main causes
This is mainly due to hormonal decline; anabolic resistance, in which muscles become less sensitive to amino acids, hindering protein synthesis; chronic inflammation due to increased inflammatory cytokines (such as IL-6 and TNF-α), which accelerates muscle breakdown; mitochondrial dysfunction, which reduces muscle endurance and recovery; and a sedentary lifestyle, since lack of exercise accelerates disuse atrophy, especially in type II muscle fibers, which are responsible for explosive strength.
Factors riesgo
In addition to age, other factors that predispose to sarcopenia include sarcopenic obesity, which is the combination of excess fat and muscle loss, common in men with a slow metabolism; endocrine diseases such as hypothyroidism or poorly controlled diabetes; alcohol and tobacco use, which reduce protein synthesis and damage muscle fibers; sleep problems; and the use of medications such as corticosteroids, chemotherapy, and some antidepressants that promote muscle breakdown.
How do you know if a person has sarcopenia?
Symptoms may be subtle at first, but include difficulty performing everyday activities such as climbing stairs, carrying grocery bags, or getting up from the floor without support; loss of strength, evident in problems opening jars, turning keys, or holding heavy objects; a decrease in muscle mass, visible with thinner arms and legs but no overall weight loss (sometimes masked by increased fat); and rapid muscle fatigue when walking short distances or after light exercise.
Some simple home tests to detect suspected sarcopenia include the chair test, which indicates muscle loss if it is difficult to stand up 5 times in a row without using your arms, and measuring walking speed, which sets off an alarm if it is less than 0.8 meters per second (for example, taking more than 6 seconds to walk 4 meters).
Medical evaluation and diagnosis
Medical diagnosis includes strength testing (dynamometry), body composition analysis such as DEXA or bioimpedance, a physical performance evaluation with walking speed tests, and blood tests to measure testosterone levels and inflammatory proteins.
How does sarcopenia affect male sexuality?
Muscle loss impacts men's sex lives in several ways:
- Firstly, there is a decrease in the testosterone, low levels of which reduce libido and can cause erectile dysfunction.
- Fatigue and physical endurance may also occur, with muscle weakness limiting stamina during sexual intercourse; self-image issues, as loss of muscle tone can affect confidence and self-esteem; and poor blood circulation, with weak muscles contributing to poor vascularization, which is essential for achieving an erection.

Consequences and risks
If left untreated, sarcopenia can lead to an increased risk of falls and fractures, as weakness in the legs and hips increases the likelihood of hip fractures. It can also lead to the development of frailty syndrome, which is the loss of autonomy in bathing, dressing, or cooking, and metabolic complications, as muscle mass is key to regulating glucose, and its loss worsens insulin resistance.
All of this can lead to frequent hospitalizations. Sarcopenic patients have a worse postoperative recovery and an increased risk of mortality. Men with severe sarcopenia are estimated to have a 50% increased risk of premature death.
How to treat muscle loss?
Nutrition and recommended diet
High-quality proteins such as eggs, lean meat, fish, and dairy products should be consumed. Vitamin D and omega-3 supplements, which improve muscle synthesis, are also helpful. It's also important to incorporate essential amino acids such as leucine, found in whey.

What exercise is good for sarcopenia?
Resistance training with weights or elastic bands, functional exercises such as squats and step-ups, and moderate aerobic activity (brisk walking, swimming) are recommended.
Care and prevention methods
Advanced Nutrition
You should consume 1.6 to 2.2 grams of protein per kg of body weight per day, spread over 4 to 5 meals, and you can take key supplements such as creatine (5 g/day), which improves strength and recovery, vitamin D (2000 IU/day if deficient), and omega-3 (2 g/day), which reduces muscle inflammation.
specific training
Progressive resistance exercises are recommended, such as lifting weights three times a week, focusing on the legs (squats) and core (bench press); eccentric exercises with movements that emphasize the muscle elongation phase (for example, slowly lowering into a squat); and vibration training, which uses vibrating platforms to improve strength in older adults.
Medical and hormonal control
One option to consider is testosterone replacement therapy if there is a confirmed deficiency. Inflammatory markers (CRP, IL-6) should be assessed, and annual muscle densitometry is recommended for men over 60 years of age.
Complementary habits
It is necessary to have 7 to 8 hours of sleep to optimize GH production, reduce stress, since high cortisol accelerates muscle breakdown, and it is recommended to have 15 to 20 minutes of sun exposure a day to promote vitamin D synthesis.
