How to Treat Low Testosterone in Men Over 45

Many men over 45 notice changes in energy, sex drive, and body composition. These signs can point to low testosterone, a common but treatable condition. Understanding diagnosis, treatment options, and safety helps men make informed choices with their provider.

This guide explains how clinicians evaluate low testosterone, the most used TRT protocols, how HCG preserves fertility, monitoring plans, and natural steps you can take now. It includes specific examples, dose ranges, lab targets, and California-focused guidance to help you find appropriate care.

Why testosterone drops after 45

Testosterone naturally declines about 1 to 2 percent per year starting in the 30s. By the mid-40s and beyond, cumulative decline plus lifestyle factors often produce symptoms. Common contributors include excess weight, sleep apnea, chronic stress, certain medications, and testicular or pituitary disease.

Key symptoms to watch for

Not every man with low testosterone has the same pattern of symptoms. Look for a cluster of issues rather than a single complaint.

• Sexual dysfunction – lower libido and difficulty achieving or maintaining erections.
• Fatigue and low motivation – persistent tiredness despite normal sleep routines.
• Body composition changes – increased belly fat and reduced muscle mass despite strength training.
• Mood changes – irritability, mild depression, or loss of confidence.
• Physical complaints – reduced bone density, hair loss, and poor recovery from workouts.

How providers diagnose low testosterone

Diagnosis combines symptoms with specific lab tests. A reliable approach minimizes false positives while identifying underlying causes.

• Obtain at least two morning total testosterone measurements done before 10 a.m. on separate days.
• Consider free testosterone if total is borderline or if SHBG abnormalities exist.
• Order LH and FSH to differentiate primary testicular failure from secondary (pituitary) causes.
• Check prolactin if secondary hypogonadism is suspected, and measure estradiol when gynecomastia or high estrogen symptoms are present.
• Baseline safety labs: hematocrit, PSA, lipid panel, liver function, and fasting glucose or HbA1c.

General thresholds vary, but many clinics use total testosterone under 300 ng/dL on repeated morning tests plus consistent symptoms as the treatment trigger. Clinical context matters, so discuss borderline numbers with your clinician.

TRT protocols: options and example dosing

Testosterone replacement comes in several formulations. Choice depends on goals, convenience, fertility plans, cost, and side-effect profile.

Intramuscular injections

Injections are common and cost-effective. Typical regimens include:

• Testosterone cypionate or enanthate: 50 to 100 mg twice weekly, or 100 to 200 mg every 7 to 10 days. More frequent, lower doses reduce mood swings and peaks.
• Monitor trough levels 48 to 72 hours after injection to aim for mid-normal serum testosterone.

Topical gels and creams

Gels (1% or 1.62%) are applied daily to shoulders, upper arms, or abdomen. Typical total dose is 50 to 100 mg of gel depending on preparation. Skin transfer risk requires careful application and hygienic measures.

Subcutaneous pellets

Pellets implanted every 3 to 6 months provide steady levels. Common doses range from 75 to 150 mg per pellet, with total dose based on body composition. Discuss procedure risks and removal options with your provider.

Oral and alternative agents

Oral testosterone undecanoate is available in some countries, but bioavailability varies. Clomiphene citrate or enclomiphene can stimulate endogenous testosterone in men with secondary hypogonadism and are an option when fertility preservation is a priority.

Fertility and HCG therapy

Standard TRT suppresses spermatogenesis in many men and can reduce fertility. If you want to preserve or restore fertility, discuss these options:

• Human chorionic gonadotropin (HCG) – commonly 250 to 500 IU subcutaneously two to three times per week. HCG mimics LH and stimulates testicular testosterone production and sperm production.
• Clomiphene citrate – 25 to 50 mg daily can raise endogenous testosterone while preserving sperm output in some men.
• In couples actively trying to conceive, work with a urologist or reproductive specialist for tailored regimens and semen analysis monitoring.

Monitoring and safety: a clear plan

Monitoring reduces risk and optimizes benefit. A typical schedule looks like this:

• Baseline labs before starting therapy: total and free testosterone, hematocrit, PSA, lipids, LFTs, and glucose.
• Recheck testosterone and hematocrit at 6 to 12 weeks after starting or changing dose. Adjust dose to keep testosterone in mid-normal range.
• Then monitor hematocrit and testosterone every 6 to 12 months. Check PSA annually or more often if baseline risk is elevated.
• If hematocrit exceeds 54 percent, pause or reduce therapy and evaluate for causes of polycythemia.

Report new chest pain, unexplained shortness of breath, or significant leg swelling promptly. Discuss cardiovascular risk factors and management with your clinician.

Evidence-based natural strategies to boost testosterone

Lifestyle changes can raise testosterone modestly and improve TRT outcomes. Use these strategies alongside medical care.

• Prioritize sleep: aim for 7 to 9 hours with consistent timing. Sleep restriction lowers morning testosterone significantly.
• Strength training and high-intensity interval training increase testosterone and muscle mass. Focus on compound lifts 2 to 4 times weekly.
• Lose excess weight: each 10 percent weight reduction can improve testosterone and insulin sensitivity.
• Check vitamin D and correct deficiency; consider 2,000 to 5,000 IU daily if low under provider guidance. Maintain adequate zinc and magnesium intake through diet or supplements if deficient.
• Limit alcohol and review medications with your clinician that may lower testosterone, like certain opioids and some antidepressants.

Choosing a TRT provider in California

California has many TRT clinics, from primary care to specialized men’s health centers. Seek providers who perform thorough evaluation, provide evidence-based options, and offer proper monitoring.

Look for these qualifications and services:

• Board-certified endocrinologists, urologists, or experienced men’s health physicians.
• On-site or affiliated laboratory testing and documented follow-up protocols.
• Telemedicine visits for convenience plus access to local labs in your city – San Diego, Los Angeles, San Francisco, and Sacramento clinics commonly support this hybrid model.
• Transparent pricing for consultations, labs, and medication. Expect wide variation – discuss insurance coverage and out-of-pocket costs up front.

Real-world example

John, 49, had low energy, weight gain, and low libido. Two morning labs showed total testosterone of 280 ng/dL. After discussing goals, he started testosterone cypionate 50 mg twice weekly with baseline HCG 500 IU twice weekly to protect fertility. At 3 months his testosterone rose to 520 ng/dL, hematocrit remained 46 percent, and his libido and energy improved. He will continue monitoring every 6 months.

Frequently Asked Questions

What is the normal testosterone level for men over 45?

Normal ranges vary by lab, but many clinicians consider total testosterone between 300 and 1,000 ng/dL as the typical adult male range. For symptomatic men over 45, persistent levels under 300 ng/dL on two morning tests often prompt further evaluation and consideration of treatment.

Will TRT cause prostate cancer?

Current evidence does not show that TRT causes prostate cancer. Providers still screen with baseline PSA and regular monitoring because TRT can stimulate PSA in men with untreated prostate disease. Discuss individual risk and screening frequency with your clinician.

Can I maintain fertility while on TRT?

Standard testosterone replacement can reduce sperm production. To preserve fertility, clinicians often add HCG 250 to 500 IU two to three times weekly or use clomiphene citrate. Work with a reproductive specialist if you are actively trying to conceive.

How soon will I notice improvement on TRT?

Some symptoms improve quickly: libido and energy may improve within 3 to 6 weeks. Muscle mass, strength, and fat loss typically take 3 to 6 months. Individual response varies, so keep expectations realistic and track progress with your provider.

What side effects should I expect?

Common side effects include acne, increased hematocrit, and mild fluid retention. Some men experience mood changes or sleep disturbances. Regular monitoring helps detect and manage side effects early.

How do I find a qualified TRT clinic in California?

Look for board-certified specialists, transparent monitoring protocols, and access to local labs. Read patient reviews and confirm the clinic performs baseline testing, documents follow-up, and discusses fertility and cardiovascular risks before starting therapy.
