What Is Hypogonadism? Signs, Causes, and How It's Treated

Feeling constantly tired, low on motivation, or noticing a drop in sexual desire?
Many people blame stress or ageing, but sometimes the real cause is a hormonal imbalance.
Hypogonadism is a condition where the body produces low levels of sex hormones, especially testosterone in men and estrogen in women.
Because sex hormones control energy, mood, muscle mass, fertility, and sexual function, low levels can affect both physical and emotional well-being.
The good news is that hypogonadism is treatable once properly diagnosed.
In our guide, you will learn what hypogonadism is, its types, causes, symptoms, diagnosis, and available treatment options.
What Is Hypogonadism?
Hypogonadism occurs when the sex glands, testes in males and ovaries in females, do not produce enough sex hormones.
In males, this mainly means low testosterone levels and in females, it involves low estrogen production.
These hormones are responsible for:
- Sexual development during puberty
- Sperm or egg production
- Libido (sex drive)
- Bone density
- Muscle mass
- Mood regulation
In men, hypogonadism is sometimes referred to as low testosterone or androgen deficiency.
It can occur at any age, from infancy to adulthood.
Types of Hypogonadism
Hypogonadism is classified based on where the problem originates.
Primary Hypogonadism
Primary hypogonadism happens when the problem lies in the testes or ovaries themselves.
The brain sends proper hormonal signals, but the gonads fail to respond adequately.
This type is also called hypergonadotropic hypogonadism.
Secondary Hypogonadism
Secondary hypogonadism begins in the brain, specifically in the hypothalamus or pituitary gland.
These parts of the brain fail to send proper signals (LH and FSH hormones) to the gonads.
It is also known as central hypogonadism or hypogonadotropic hypogonadism.
Eugonadotropic Hypogonadism
This type is more common in females.
Hormone signals from the pituitary appear normal, but ovarian hormone production remains low.
It is often associated with conditions like Polycystic Ovary Syndrome (PCOS).
What Causes Hypogonadism?
The causes depend on whether the condition is primary or secondary.
Causes of Primary Hypogonadism
Primary hypogonadism may result from:
- Genetic disorders like Klinefelter syndrome or Turner syndrome
- Autoimmune diseases such as Addison’s disease
- Undescended testes
- Testicular infections like mumps
- Radiation exposure
- Injury or surgery involving reproductive organs
- Liver or kidney disease
Causes of Secondary Hypogonadism
Secondary hypogonadism may develop due to:
- Pituitary tumors
- Kallmann syndrome
- Brain injury
- HIV infection
- Obesity
- Severe weight loss
- Chronic opioid or steroid use
- Iron overload (Hemochromatosis)
- Inflammatory conditions like tuberculosis
Symptoms of Hypogonadism
Symptoms vary depending on age, gender, and severity.
Symptoms in Males (AMAB)
Men with low testosterone may experience:
- Reduced libido
- Erectile dysfunction
- Fatigue
- Decreased muscle mass
- Loss of body hair
- Abnormal breast enlargement
- Infertility
- Hot flashes
- Difficulty concentrating
In adolescents, delayed puberty may occur.
Symptoms in Females (AFAB)
Women may experience:
- Irregular or absent menstrual periods
- Hot flashes
- Reduced breast development
- Low sex drive
- Infertility
- Osteoporosis
- Vaginal dryness
Symptoms often develop gradually and may be mistaken for stress or ageing.
At What Age Does Hypogonadism Occur?
Hypogonadism can occur at any age.
In men, testosterone levels naturally begin to decline after age 40.
This age-related form is called late-onset hypogonadism.
However, younger men may develop it due to genetic conditions, obesity, injuries, infections, or medication use.
How Is Hypogonadism Diagnosed?
Diagnosis begins with a physical examination and a review of medical history.
Doctors assess sexual development, muscle mass, and body hair patterns.
Blood tests are essential for confirmation.
Common Diagnostic Tests
- Morning testosterone levels (in men)
- LH and FSH hormone levels
- Estrogen levels (in women)
- Prolactin test
- Thyroid function test
- Iron levels
- Genetic testing
- Semen analysis (if fertility is a concern)
- MRI or CT scan (to check for pituitary tumours)
Morning testosterone testing is especially important because levels are highest at that time.
How Is Hypogonadism Treated?
Treatment depends on the cause and whether fertility is desired.
Treatment in Males
If fertility is not a concern, doctors may recommend Testosterone Replacement Therapy (TRT) or hcg injections in men.
TRT is available in:
- Injections
- Gels
- Skin patches
- Pellets
- Lozenges
If fertility is desired, treatments like GnRH or gonadotropins may stimulate sperm production instead.
Treatment in Females
Treatment focuses on restoring estrogen levels.
Options include:
- Estrogen therapy
- Combination estrogen and progesterone therapy
- FSH or hCG injections to induce ovulation
If caused by a pituitary tumour, surgery or radiation may be required.
Long-Term Outlook
Hypogonadism is often a lifelong condition.
With proper hormone replacement therapy and medical supervision, most people lead healthy and active lives.
Stopping hormone therapy may cause symptoms to return, so long-term management is important.
Emotional support, counselling, and lifestyle improvements can enhance treatment success.
Conclusion: All About Hypogonadism
Hypogonadism is more than just low hormone levels, as it affects energy, mood, fertility, and overall quality of life.
The condition may result from genetic issues, ageing, obesity, pituitary disorders, or underlying medical problems.
The key is early diagnosis and personalised treatment.
With proper medical guidance and hormone therapy when needed, hormone balance can be restored, and symptoms significantly improved.
If you suspect low testosterone or a hormonal imbalance, consult a healthcare professional for proper evaluation and treatment.
Faq
The common causes include genetic Klinefelter syndrome in men and Turner syndrome in women. However, Autoimmune diseases can also increase the risk by damaging the gonads.
Testosterone replacement therapy is the most effective treatment for Hypogonadism. The TRT can help restore sex drive, energy, muscle mass, bone density, and body hair in men.
Hypogonadism is usually chronic unless caused by a treatable condition. Hormone therapy can help manage symptoms, but stopping the treatment often leads to decreased hormone levels again.
Yes, Hypogonadism can affect male physical traits and reproductive function. Early signs include low sex drive, reduced energy, and changes in body composition. If you suspect any of these symptoms, you must consult a doctor.
Chronic stress can disrupt hormone levels and lead to hypogonadotropic Hypogonadism. The condition is more likely to appear if the body is already vulnerable to hormonal imbalance.
Hypogonadism is often permanent and linked to low reproductive hormone levels. It's rarely used to describe infertility without hormone deficiency.
