Hypergonadotropic Hypogonadism Diagram
Low testosterone (male hypogonadism) is a condition in which your testicles don’t produce adequate testosterone. It has numerous feasible reasons, consisting of problems or injuries affecting your testicles, pituitary gland or hypothalamus. It’s treatable with testosterone replacement treatment.
What is low testosterone (male hypogonadism)?

Low testosterone causes different symptoms at different ages. Testosterone levels in grownups AMAB normally decrease as they age. This consists of cisgender males, non-binary individuals AMAB as well as transgender females who aren’t undergoing feminizing hormonal agent treatment.
Various other names for low testosterone as well as male hypogonadism consist of:
Testosterone deficiency syndrome.
What does testosterone do?
Testosterone is the primary androgen. It stimulates the advancement of male features and is crucial for sperm manufacturing (spermatogenesis). Degrees of testosterone are naturally a lot greater in people designated AMAB than in individuals assigned woman at birth (AFAB).
In people assigned AMAB, testosterone helps create and also keep :
Sex organs and genitalia.

Your hypothalamus launches gonadotropin-releasing hormone (GnRH), which triggers your pituitary gland to release luteinizing hormonal agent (LH). LH then travels to your gonads ( testicles or ovaries ) and promotes the production as well as release of testosterone. Your pituitary also launches follicle-stimulating hormonal agent (FSH) to create sperm production.
Any concern with your testicles, hypothalamus or pituitary gland can create low testosterone (male hypogonadism).
What is a low testosterone degree?
The American Urology Association (AUA) takes into consideration low blood testosterone to be less than 300 nanograms per deciliter (ng/dL) for adults.
Nonetheless, some scientists as well as healthcare providers disagree with this and also feel that degrees listed below 250 ng/dL are reduced. Companies also take signs and symptoms right into factor to consider when diagnosing low testosterone.
Who does low testosterone (male hypogonadism) impact?
Male hypogonadism is a medical problem that can influence people with testicles at any type of age from birth through the adult years.
Low testosterone is more probable to affect individuals that:
Have actually inadequately taken care of Type 2 diabetes mellitus.
Have obstructive sleep apnea.
Have chronic medical problems, such as kidney dysfunction or cirrhosis of the liver.
Exactly how usual is low testosterone? Hypergonadotropic Hypogonadism Diagram
It’s difficult for scientists to estimate exactly how common low testosterone is since various researches have various definitions for low testosterone.
Information recommend that about 2% of people AMAB may have low testosterone. And also other researches have estimated that greater than 8% of people AMAB aged 50 to 79 years have low testosterone.
What are the signs of low testosterone?
Signs of low testosterone can differ substantially, especially by age.
Signs that very suggest low testosterone in grownups assigned man at birth consist of:
Loss of underarm and pubic hair.
Low or absolutely no sperm matter (azoospermia), which triggers male inability to conceive.
Various other signs and symptoms of low testosterone in grownups AMAB include:
Clinically depressed mood.
Troubles with focus and memory.
Boosted body fat.
Bigger male bust cells (gynecomastia).
Decrease in muscular tissue stamina as well as mass.
Reduction in endurance.
Signs of low testosterone in kids
Low testosterone before or during adolescence for kids designated male at birth can lead to:
Slowed development in height, yet their limbs might continue to outgrow percentage with the rest of their body.
Decreased growth of pubic hair.
Decreased growth of their penis and also testicles.
Much less voice growing.
Lower-than-normal toughness and also endurance.
What triggers low testosterone?
There are several feasible sources of low testosterone. Both types of male hypogonadism are:
Primary hypogonadism (testicular condition).
Secondary hypogonadism (pituitary/hypothalamus disorder).
Causes of primary and secondary hypogonadism are also split into either hereditary (at birth) or acquired ( created later on in youth or the adult years).
Sources of primary male hypogonadism
When something is wrong with your testicles that doesn’t permit them to make typical degrees of testosterone, primary hypogonadism takes place.
In this kind, your pituitary gland produces more luteinizing hormonal agent (LH) and follicle-stimulating hormonal agent (FSH) (known as gonadotropins) in action to low testosterone levels. The high levels of these hormonal agents would generally inform your testicles to generate more testosterone and sperm.
Just how is low testosterone treated?
Healthcare providers deal with low testosterone (male hypogonadism) with testosterone substitute treatment. Testosterone replacement therapy has numerous different types, consisting of:
There’s no single solution for low testosterone. Nonetheless, consistent hormone replacement treatment assists boost sex drive, ease signs and symptoms of clinical depression and increase power degrees for many individuals designated man at birth (AMAB) experiencing low testosterone.
