Testosterone Replacement Therapy – What Is It?

Testosterone replacement therapy (TRT) is a kind of treatment that can safely restore hormone levels to a optimal range.

By age 30, the human body starts decreasing its production of testosterone. TRT utilizes bio-identical hormones to keep the body healthy and strong.

Testosterone is produced by the testicles in men and by the ovaries in women. Some is also produced in the adrenal glands.

When these organs and glands decline in their function, so does the production of testosterone.


A depletion of testosterone in the body can lead to problems, but TRT can decrease negative issues and help to allow the individual to feel energetic, vibrant, happy and emotionally sound. It can also help with sexual libido, muscle retention, keeping bones strong and the immune system resilient.

When the testicles slow in production of testosterone, this is called hypogonadism. In women, this Is called Andropause.

Experts say that over 200,000 men and women per year are affected by this condition. The International Journal of Clinical Practice gives these alternative names for hypogonadism:

  • Testosterone deficiency syndrome
  • Low testosterone
  • Low T
  • Androgen deficiency syndrome
  • Androgen deficiency in the ageing male (ADAM)
  • Andropause
  • Late onset hypogonadism
  • Male menopause 
  • Partial androgen decline in the ageing male (PADAM)

Each name means the same thing. A man will have negative symptoms due to the absence of the vital hormone testosterone. This condition cannot be cured, but it can be treated safely, legally and effectively with hormone replacement therapy.

Why Does Your Body Need Testosterone?

Both male and female bodies need testosterone. The hormone acts as a chemical messenger signaling the body to create new blood cells to protect bones, muscles, sex drive, emotional health, weight management and so much more.

Testosterone is responsible for regulating the secretion of both follicle stimulating hormone and luteinizing hormone.

Most people who are experiencing a depletion in testosterone may have noticeably uncomfortable symptoms. This can create a decrease in their overall quality of life.

The body needs testosterone from birth to continue growing and to remain healthy and strong. Approximately at age 30 is when testosterone levels start to deplete in most people.

Below is a chart to show testosterone depletion by age:

Ages 0 to 13 – Rare
Ages 14 to 30 – Not common
Ages 30 to 60 – Common
Ages over 60 – Very common

Males are considered to be more commonly affected by low testosterone in their lifetimes than women. However, both genders may experience the issue.

Low T can be the cause of weakness and lethargy in otherwise healthy older men and women. It can also affect sex drive, sexual performance, bone density, emotional health and more.

The Purpose Of Testosterone Replacement Therapy

The purpose of testosterone replacement therapy is to help a person with low testosterone levels to live a fuller, happier life by keeping hormones leveled and balanced. This will keep the person’s body working at optimal performance.

Keeping hormone levels balanced is the way to help both men and women stay full of energy, stamina, endurance, have a good sex life and an appetite for an exciting life well into their golden years.

Signs, Symptoms And Causes Of Low T Levels

One of the most common causes of low T levels is age. Growing older leads to decrease in function of the glands, (the testes, the ovaries and the adrenal glands), and organs that produce the vital hormone, testosterone.

The signs and symptoms of low T levels are:

  • Lowered sexual desire
  • Erectile dysfunction
  • Vaginal dryness
  • Weakness
  • Fatigue
  • Lethargy
  • Mild to moderate depression
  • Anxiety
  • Irritability
  • Mood swings
  • Agitation
  • Anger outbursts
  • Low bone mineral density
  • Easy fracturing or breaking of bones
  • Higher LDL cholesterol levels
  • Higher triglyceride levels
Sexual Problem
  • Higher risk for disease such as osteoporosis, heart attack and stroke
  • Weak skin elasticity
  • More noticeable wrinkles and sagging skin
  • Difficulty with concentration and focus
  • A mental foggy feeling
  • Sleeplessness

Not all people with low testosterone levels will feel all these signs and symptoms. In addition, age, body composition, and body chemistry will determine which symptoms will occur, at what age they will happen and their severity.

Low Testosterone Diagnosis

Low T Diagnosis

It is necessary to get a low testosterone diagnosis from a licensed doctor before you can begin TRT.

This will usually involve a blood test to check testosterone levels and a physical examination to look for signs of low T.

In addition, a prospective patient must fill out a medical history form. All this information is imperative to get.

This is how a doctor can write an accurate diagnosis, the right prescription and individualized treatment plan.

This will help to produce the best results from therapy.

What is involved in getting tested for low testosterone levels?

Blood Test To Check Free and Total Testosterone LevelsPhysical Examination To Check For Signs Of Low TestosteroneMedical History Form To Get A Good Overall Picture Of Health

**Hormone testing for men and women differ due to differences in body function and active hormones**

Doctors look for ranges of free and total testosterone to be approximately:

Total Testosterone: 250 – 1,200 ng/dL (men); 5-48ng/dl (women)

Free Testosterone: 5 – 31 ng/dL (1-4% of total serum, both men and women)

Since testosterone levels usually fluctuate during the day, testing should take place in the morning (between 7 am and 10 am) when testosterone levels are at their peak

Doctors examine for:

  • Size of breasts, penis, scrotum and testes
  • Amount of body hair
  • Lumps in the testes or scrotum
  • Peripheral vision

Doctors find out about:

  • Patient medical history
  • Family medical history
  • Patient lifestyle
For optimal therapy results other tests are needed to determine the overall function of the body’s hormonal system.

Active Estrogen levels: 7-45pg/ml (men); 0.2-390pg/ml (women)

IGF-1: 42-400ng/ml (For pituitary function, both)

Thyroid: 0.45-4.50uIU/ml (both)

Progesterone: 0.1-75.8ng/ml (women)

DHEA: 20.4-386 (both)

Doctors may inquire as to:

  • Familial genetic conditions
  • Patient lifestyle
  • Sexual drive
  • Past or current medical conditions
  • Any past or present sexual dysfunction
  • Any previous diagnoses of low T

All this information together will tell the doctor why a patient is experiencing their symptoms.

If a patient has low testosterone levels according his or her medical testing, a doctor can give him or her a diagnosis and prescribe the correct medications and treatment plan.

A plethora of research has proven that TRT can be very successful when done correctly with the right diagnosis and with a doctor’s medical supervision.

Testosterone Replacement Therapy For Men And Women


Testosterone deficiencies can be treated in both men and women safely and effectively. Although most people wrongly believe that testosterone is a hormone that is only important for men.

Women need this hormone (in a lesser amount) as well in order to reach optimal health. Properly prescribed TRT can produce remarkable results for men and women with a testosterone deficiency.

There are two different ways that testosterone can be delivered to men and women:

  • Most males will use intramuscular injections. Injections will be self-administered about every week and will be delivered into the buttocks, thighs or deltoids.
  • Females will use a cream or gel. The cream or gel will applied to the skin on a daily basis. It gets absorbed quickly and reaches the blood stream this way.

Testosterone therapy for men and women has been successful for years now. Experts share that treatment of this kind is not for everyone. This is the reason that getting tested is imperative.

There are so many benefits to raising and balancing testosterone levels and they all can lead to a much better overall quality of life.

How Do I Know If Testosterone Replacement Therapy Is Right For Me?

Before you can begin to get tested for a hormone deficiency, you will have a complimentary telephone consultation with an expert advisor.

After you ask all your questions about TRT and understand this kind of treatment better, you will be able to make your decision as to whether or not testosterone replacement therapy is right for you.

After you decide that you would like to proceed with TRT, testing will take place to see if your issues are being caused by low testosterone levels. If they are, you will hopefully be more confident that TRT is right for you.

What Results Can I Expect From Testosterone Replacement Therapy?

Every person is different, with varying body types, body composition and body chemistry. Therefore, what results to expect from testosterone replacement therapy can be diverse.

In general, here is a list of the benefits of therapy and what most people who partake in TRT can expect:
