Testosterone Replacement Therapy
Low Testosterone (Low T)
Low energy, weaker sex drive, brain fog, weight gain, and flat mood often travel together. For many men, those changes trace back to low testosterone.
At Riverstone Urology Specialists in Cypress, Dr. Russell Libby evaluates and treats low testosterone as a full health issue, not only a hormone number. He looks at symptoms, lab results, underlying causes, and long term risks before talking about testosterone replacement or alternatives.
What Is Low Testosterone
Low testosterone, also called male hypogonadism, means the testicles are not producing enough testosterone for the body’s needs. Problems can start in the testicles themselves, called primary hypogonadism, or in the brain centers that control them, the hypothalamus and pituitary, called secondary hypogonadism.
Guidelines Define Testosterone Deficiency As:
- Symptoms and signs that fit testosterone deficiency
- Repeated morning blood tests that show testosterone below a clear cutoff, often around 300 ng/dL for total testosterone, using accurate lab methods
Dr. Libby treats the lab number and the symptoms together, not the number alone.
Common Symptoms Of Low Testosterone
Symptoms Vary From Man To Man, But Common Patterns Include:
- Lower sex drive
- Erectile dysfunction or weaker erections
- Fewer morning or spontaneous erections
- Fatigue and low energy
- Depressed mood or irritability
- Less motivation and focus
- Loss of muscle strength and mass
- Increased body fat, especially around the waist
- Reduced shaving frequency or body hair
- Lower bone density and higher fracture risk in long term cases
These symptoms can come from other problems too, which is why a structured evaluation matters.
Why Testosterone Drops
Testosterone levels naturally drift down with age, often about 1 to 2 percent per year after midlife. At the same time, several factors speed that decline or change how the body responds to testosterone.
Common Contributors:
- Obesity and insulin resistance
- Type 2 diabetes
- Obstructive sleep apnea
- Long term opioid or steroid use
- Testicular injury, infection, or surgery
- Pituitary or hypothalamic disorders
- Prior chemotherapy or radiation
- Chronic illnesses such as kidney or liver disease
- Genetic conditions, for example Klinefelter syndrome
Sorting out which of these apply to you shapes treatment choices later.
Why Low T Matters For Overall Health
Low Testosterone Links To More Than Sex Drive And Gym Performance. Studies Show Connections With:
- Higher body fat and lower muscle mass
- Lower bone density and fracture risk
- Higher rates of type 2 diabetes and metabolic syndrome
- Mood changes and lower quality of life
Low T also overlaps with erectile dysfunction and cardiovascular risk. ED can be an early signal of artery disease, and low testosterone often sits in the same cluster of risk factors.
Dr. Libby uses a low T visit as a chance to look at the bigger picture of your health, not only your hormone panel.
When To See Dr. Libby
A Visit Makes Sense If You Notice Several Of These:
- Ongoing low sex drive
- Erection problems, even when relationships are stable
- Fatigue that persists despite decent sleep
- Unexplained weight gain around the middle
- Lower strength in the gym or daily life
- Persistent low mood or brain fog
You should also get checked if a prior doctor mentioned low testosterone on a lab result and no one fully explained what it means.
How Dr. Libby Evaluates Low Testosterone
Evaluation At Riverstone Urology Follows Guideline Based Steps.
History And Physical Exam
- Symptom review: libido, erections, energy, mood, sleep, weight, exercise
- Past medical problems such as diabetes, heart disease, sleep apnea, or infertility
- Medication and supplement list, including opioids, steroids, and antidepressants
- Prior testicular injury, infections, or surgery
- Family history of hormone or pituitary problems
Exam Focuses On
- Weight, waist size, and blood pressure
- Testicular size and consistency
- Breast tissue, body hair pattern, and signs of endocrine disease
Targeted Lab Testing
- Morning total testosterone, drawn on at least two different days
- Free or bioavailable testosterone when needed
- LH and FSH to separate primary from secondary hypogonadism
- Prolactin and other pituitary tests when indicated
- Thyroid labs, fasting glucose or A1c, and lipids to check metabolic health
In selected cases, Dr. Libby orders pituitary imaging or refers to endocrinology if a central hormone problem is likely.
Lifestyle And Medical Foundation Before Hormones
Guidelines and large studies agree on one thing. Lifestyle and underlying medical issues matter as much as the hormone prescription.
Key Targets:
- Weight loss when you carry extra weight around the waist
- Regular exercise, including resistance training and walking or other cardio
- Sleep apnea evaluation and treatment
- Smoking cessation
- Better control of diabetes, blood pressure, and cholesterol
These steps often raise testosterone on their own and improve how you feel even if you still need hormone therapy later. At Riverstone Urology, this foundation ties into the practice’s weight loss, semaglutide and tirzepatide, and TRT alternatives programs when appropriate.
Treatment Options For Low Testosterone
Once symptoms, labs, and causes are clear, you can talk through hormone and non hormone options. Treatment usually falls into three broad paths.
Testosterone Replacement Therapy (TRT)
TRT raises testosterone by adding hormone from outside the body. Common delivery methods include:
- Injections
- Gels or patches
- Long acting pellets such as Biote, described in detail on a separate Riverstone Urology page
TRT can improve libido, erections, energy, mood, and muscle mass in many men with confirmed deficiency.
Important Points Dr. Libby Covers Before Starting TRT:
- The need for regular monitoring of blood counts, PSA, and hormone levels
- Possible side effects such as higher red blood cell counts, swelling, acne, or breast tenderness
- Uncertain long term cardiovascular risk signals in some studies, which he discusses openly
- TRT is not a fertility treatment and often lowers sperm counts
Men who choose TRT enter a structured monitoring plan, not a one time prescription.
TRT Alternatives And Fertility Friendly Options
For men who want to preserve fertility or avoid direct testosterone replacement, Dr. Libby may discuss:
- Medicines that stimulate the body’s own hormone production, for example clomiphene or hCG in selected cases
- Focused weight loss and metabolic programs
- Treatment of sleep apnea and other drivers that suppress testosterone
These options often raise testosterone more gently and protect sperm production better than standard TRT, although effects can be smaller and slower. TRT alternatives at Riverstone Urology have their own dedicated page with more detail.
Treating The Root Cause
Sometimes the best “testosterone treatment” is fixing the underlying problem. Examples:
- Adjusting or changing a medicine that suppresses testosterone when safe
- Treating pituitary disease in partnership with endocrinology
- Addressing uncontrolled diabetes or chronic illness with your primary care team
Dr. Libby works with your other doctors so hormone care fits inside your overall medical plan.
Low Testosterone, Erections, And Sexual Health
Low testosterone and erectile dysfunction overlap but are not identical. Some men with low T have normal erections. Others with ED have normal testosterone. Often there is a mix.
At Riverstone Urology:
- Testosterone is checked as part of a full ED workup
- TRT or Biote pellets are considered when low testosterone is clear and symptoms match
- PDE5 inhibitors, injection therapy, wave therapy, or implants are used when blood flow or structural issues drive the ED
You and Dr. Libby decide how to combine hormone and ED treatments in a way that fits your goals for sex, energy, and long term health.
Monitoring And Long Term Follow Up
Low T Care Does Not End When You Feel Better. Ongoing Follow Up Protects You. Typical Monitoring Includes:
- Regular symptom reviews
- Repeat testosterone testing to avoid under or over treatment
- Blood counts to watch for high red cell levels
- PSA and prostate checks for age appropriate cancer screening
- Periodic review of heart, metabolic, and sleep risk
If your life situation changes, for example a new plan for children or new medical diagnosis, Dr. Libby adjusts the hormone plan to match.
