Diagnosis and Management of Hypogonadism
Conditions associatedwith alterations in sex hormone binding globulin (SHBG) concentrations and lower/higher free testosterone
Conditions associated with decreased SHBG concentrations
Bone mineral density (by DEXA) is not usually included in monitoring schedule since it may be only an important variable only for men with ages 65 and over. TRT increases BMD and lowers the risk of fractures.
The following are the required blood tests and how to use them for clinical decision making. You can get them cheaply in most U.S. cities here
• Initial Blood Test – New Patient
– Testosterone, Free & Total
– PSA
– LH & FSH
– Lipids
– CBC
– CMP
-Free T3
-Sensitive Estradiol
If T <200 ng/dL and no current/past use of anabolics or opiates, test for prolactin.
If free T3 is low, perform a complete thyroid panel including antibodies and reverse T3.
• Initial Blood Test – Transferring Patient from one clinic to another (currently on testosterone or has been in last 3 months)
Fasted, morning and well hydrated conditions:
– Testosterone, Free & Total
– PSA
– LH & FSH
– Lipids
– CBC
– CMP
– Estradiol, sensitive
– Free T3
• 6wk Follow up – 6wks after initial Rx
Fasted, morning sample and well hydrated conditions:
– CBC
– CMP
– Testosterone, Free & Total
– Estradiol, sensitive
– Free T3
• 6 Month Follow up – 6 months after initial RX
– Testosterone, Free & Total
– PSA (optional based on week 6 results)
– Lipids
– CBC
– CMP
– Estradiol, sensitive
– Free T3 (if abnormal FT3 was found at baseline and thyroid treatment was provided)
• Annual Blood Test – Same as 6 months (plus PSA)

Diagnosis Of Hypogonadism
Symptoms and signs suggestive of testosterone deficiency in men:A. More specific symptoms and signs
• Incomplete or delayed sexual development, eunuchoidism • Reduced sexual desire (libido) and activity • Decreased spontaneous erections during sleep • Breast discomfort, gynecomastia • Loss of body (axillary and pubic) hair, reduced shaving • Very small (especially <5 ml) or shrinking testes • Inability to father children, low or zero sperm count • Height loss, low trauma fracture, low bone mineral density • Hot flashes, sweatsB. Other less specific symptoms and signs
• Decreased energy, motivation, initiative, and self-confidence • Feeling sad or blue, depressed mood, dysthymia • Poor concentration and memory · Decreased penile sensitivity • Sleep disturbance, increased sleepiness • Mild anemia (normochromic, normocytic, in the female range) • Reduced muscle bulk and strength • Increased body fat, body mass index • Diminished physical or work performanceADAM questionnaire about symptoms of low testosterone (Androgen Deficiency in the Aging Male)
This basic questionnaire can be very useful for men to describe the kind and severity of their low testosterone symptoms.- Do you have a decrease in libido (sex drive)? Yes No
- Do you have a lack of energy? Yes No
- Do you have a decrease in strength and/or endurance? Yes No
- Have you lost height? Yes No
- Have you noticed a decreased “enjoyment of life” Yes No
- Are you sad and/or grumpy? Yes No
- Are your erections less strong? Yes No
- Have you noticed a recent deterioration in your ability to play sports? Yes No
- Are you falling asleep after dinner? Yes No
- Has there been a recent deterioration in your work performance? Yes No
Blood Tests and Physical Exam
Total testosterone (TT) blood level of 400 ng/dL or below along with hypogonadism symptoms not caused by temporary factors (lack of sleep, recent excess weight gain, thyroid dysfunction, temporary illness, and anabolic steroid use). For men with TT > 400 ng/dL, lifestyle modification counseling to lower BMI (If BMI >26), improve sleep hygiene, and exercise is recommended. These are other interventions that may increase testosterone in men: How to Increase Testosterone Naturally Free Testosterone (FT) blood levels should be at least 2 percent of TT. Not much can be done to manipulate sex hormone binding globulin (SHBG) to increase FT levels since it may be determined by genetics, comorbidities, insulin or inflammation. People with diabetes and hyperglycemia may have lower levels of sex hormone binding globulin even in the presence of low TT. Men on anabolic steroids may also have low sex hormone binding globulin. Higher TRT dose (over 200 mg/week of T injections) may also decrease sex hormone binding globulin. There are several types of hypogonadism depending on the level of LH, FSH and testosterone:- Moderate obesity*
- Nephrotic syndrome*
- Hypothyroidism
- Use of glucocorticoids, progestins, and androgenic steroids*
- Acromegaly
- Diabetes mellitus*
- Aging*
- Hepatic cirrhosis and hepatitis*
- Hyperthyroidism
- Use of anticonvulsants*
- Use of estrogens
- HIV disease
