What is Late-Onset Hypogonadism?

Late-onset hypogonadism (LOH) is a decrease in serum testosterone to clinically symptomatic levels in men due to age-related decline in Leydig cell function and disruption of the hypothalamic-pituitary-gonadal axis. It is also called 'andropause' or 'male menopause.'

Testosterone declines with age in every man, but the clinical picture varies widely between individuals. Obesity, type 2 diabetes, metabolic syndrome, and chronic illnesses increase the risk and severity of LOH.

Morning total testosterone measurement (at least two separate measurements) and symptom assessment (AMS or ADAM questionnaire) are required for diagnosis. Before deciding on testosterone replacement, prostate cancer, polycythemia, and obstructive sleep apnea must be assessed.

Symptoms

Decreased libido and sexual interest
Erectile dysfunction
Fatigue, low energy, and apathy
Decrease in muscle mass and strength
Abdominal fat accumulation
Depression, irritability, and difficulty concentrating
Decreased bone density

Risk Factors

Older age (>50 years)
Obesity and metabolic syndrome
Type 2 diabetes
Chronic illnesses (COPD, renal failure, liver disease)
Use of opioids or corticosteroids
Sleep apnea

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Loss of libido, fatigue, and muscle weakness coexisting in a middle-aged or older man
  • Erectile dysfunction warranting hormone evaluation
  • When low testosterone level is detected
  • When low testosterone contribution to osteoporosis is being investigated

Treatment Methods

01
Lifestyle: weight loss, exercise, and improved sleep quality (contribute to testosterone increase)
02
Testosterone replacement therapy (TRT): gel, injection, or transdermal forms
03
Before starting TRT, baseline PSA and hematocrit are measured
04
Hematocrit, PSA, and clinical response are evaluated every 3-6 months during TRT
05
Active prostate cancer, hematocrit >54%, high cardiovascular risk: contraindication or careful evaluation for TRT
06
Clomiphene citrate or gonadotropins may be options when fertility preservation is desired

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
