Endocrine Society testosterone therapy hypogonadism diagnosis morning repeat testosterone guideline

Reading File

If you mean raising testosterone naturally in men, focus on factors that affect overall hormone health rather than supplements:

Sleep 7-9 hours nightly. Regular poor sleep and untreated sleep apnea can lower testosterone and worsen libido and energy.
Lose excess body fat if applicable. Obesity can lower measured total testosterone by reducing SHBG, and addressing obesity may reverse some cases without testosterone medication. Harrison’s Principles of Internal Medicine, 22e, hypogonadotropic hypogonadism section.
Strength train regularly. Resistance training supports muscle mass and produces short-term testosterone increases. Aim for 2-4 sessions weekly, progressing gradually.
Eat enough, especially protein and healthy fats. Avoid crash diets and prolonged severe calorie restriction. Correct a real deficiency such as vitamin D, zinc, or iron, but do not take high-dose supplements blindly.
Limit heavy alcohol use and avoid anabolic steroids. Anabolic steroids can shut down the body’s own testosterone and impair fertility. Recent evidence also links chronic alcohol intake with disruption of the male gonadal axis, as summarized in this 2024 meta-analysis.
Manage stress and chronic illness. Diabetes, certain medicines such as opioids or glucocorticoids, pituitary/testicular disorders, and systemic illness can contribute to low testosterone.

Do not rely on “testosterone boosters.” Most have weak evidence, variable quality, and some can harm the liver or interact with medications.

If you have low libido, fewer morning erections, erectile dysfunction, infertility, loss of muscle, breast enlargement, anemia, or unexplained fatigue, get evaluated rather than self-treating. Proper diagnosis requires symptoms plus at least two low early-morning testosterone blood tests, typically collected around 7-10 AM, according to the Endocrine Society patient guidance. Clinicians may then check LH, FSH, prolactin, thyroid status, and related causes.

Testosterone replacement therapy is not a general energy or gym supplement. It can suppress sperm production, so it is usually inappropriate if you are trying to conceive, and it needs medical monitoring. The Endocrine Society guideline advises against it in several situations, including near-term fertility plans, untreated severe sleep apnea, elevated hematocrit, and certain prostate or breast cancer concerns.

Endocrine Society hypogonadism two morning testosterone tests symptoms free testosterone SHBG

Reading File

You cannot tell reliably from symptoms alone. Low testosterone, or hypogonadism, is diagnosed only when you have both:

Symptoms or signs that fit low testosterone, and
Consistently low blood testosterone on repeat early-morning testing.

Symptoms that make testing reasonable

Common symptoms include:

Reduced sexual desire
Fewer or absent morning erections
Erectile difficulties, though these often have other causes
Infertility or low sperm count
Reduced energy, depressed mood, or poor concentration
Loss of muscle mass/strength or increased body fat
Reduced shaving/body-hair growth
Breast enlargement or tenderness
Low-trauma fractures, reduced bone density, or unexplained anemia

Fatigue alone is not specific. Poor sleep, depression, stress, obesity, alcohol, thyroid disease, anemia, diabetes, some medications, and sleep apnea can cause very similar symptoms.

How testing should be done

Ask a clinician for:

Total testosterone on two separate mornings, ideally fasting and collected about 7-10 AM or at least before 10 AM.
Do not test when you are acutely ill, severely sleep-deprived, or immediately after extreme training, since results can be temporarily low.
If total testosterone is borderline or conditions may alter SHBG, such as obesity, aging, thyroid/liver conditions, or some medications, ask about SHBG and calculated free testosterone.
Goldman-Cecil Medicine notes that morning testing is important because testosterone has a daily rhythm and that free or calculated free testosterone can help when SHBG is abnormal, p. 2539.

If the values are repeatedly low, the next tests commonly include:

LH and FSH to distinguish testicular from pituitary/hypothalamic causes
Prolactin, especially if LH is low or normal
Sometimes thyroid tests, iron studies, blood count, glucose/A1c, and fertility testing depending on symptoms

The Endocrine Society’s diagnostic guidance similarly recommends diagnosis only when symptoms are accompanied by unequivocally and consistently low total and/or free testosterone.

Important cautions

Do not start testosterone from an online clinic or supplement result based on one low value.
Tell the clinician if you use opioids, corticosteroids, anabolic steroids, finasteride, psychiatric medicines, or recreational drugs. These can affect sexual function or testosterone.
If you want children soon, say so before treatment. Prescribed testosterone can markedly reduce sperm production.

Seek medical care promptly if low sexual function accompanies headache, loss of peripheral vision, nipple discharge, very small testes, or a testicular lump, because these can point to a pituitary or testicular condition.

male infertility AND semen analysis

ASRM male fertility semen analysis pregnancy infertility evaluation 12 months 6 months age 35

You cannot reliably know that someone can father a child without a test or trying to conceive.

Normal erections, libido, ejaculation, semen volume, or body hair do not prove fertility.
A person can have normal sexual function and still have very low sperm count, poor sperm movement, blocked ducts, or genetic/hormonal issues.
The only real-life evidence without testing is having caused a pregnancy before, but even that does not guarantee current fertility. Fertility can change with age, illness, surgery, medications, testosterone/anabolic steroid use, infections, and other factors.

Things that make reduced fertility more likely include:

Previous undescended testicles, testicular injury/torsion, mumps affecting the testes, varicocele, or genital surgery
Chemotherapy or radiation
Use of testosterone injections/gels or anabolic steroids
Problems with erections or ejaculation
Very small testes, absent puberty changes, or prior infertility

But none of these can confirm infertility by themselves.

If a couple has regular unprotected sex and pregnancy has not occurred after 12 months when the female partner is under 35, or after 6 months when she is 35 or older, both partners should be assessed. The usual first male assessment is a semen analysis, although even a normal result does not guarantee pregnancy. The AUA/ASRM male-infertility guideline explains these timelines and why male and female evaluation should occur together.
