Definition and types of hypogonadism
Hypogonadism is an endocrine disorder that involves an inadequate production of sex hormones. There are different types of hypogonadism, which are mainly classified into primary and secondary hypogonadism, each with different characteristics and causes.
Primary hypogonadism
This type of hypogonadism It originates in the testicles, where an insufficient amount of testosterone is produced. It is often associated with congenital conditions or damage to testicular function. In this type, the production of gonadotropic hormones (LH hormone y FSH hormone) is typically elevated as the pituitary gland attempts to stimulate the testicles to produce sex hormones.
Secondary hypogonadism
El secondary hypogonadism It is caused by problems in the pituitary gland or hypothalamus, which affects the hormonal signaling necessary for the production of testosterone in the testicles. In this case, LH and FSH levels are usually low or normal. This type can result from factors that affect the central nervous system, such as certain diseases or trauma.
Differences between male and female hypogonadism
While male hypogonadism focuses on testosterone deficiency and its associated effects, female hypogonadism affects the production of estrogen and progesterone. Clinical manifestations also vary between genders, considering the different hormonal physiology.
Male hypogonadism
In men, symptoms may include decreased sexual desire, erectile dysfunction, and emotional and physical changes. These characteristics are mainly due to a lack of testosterone, which is crucial for male development and maintenance.
Female hypogonadism
In women, insufficient production of sex hormones can lead to menstrual irregularities, fertility problems and decreased bone mass. Lack of estrogen can have a significant impact on a woman's overall health.
Causes of primary hypogonadism
The causes of primary hypogonadism can be classified into two main groups: genetic and acquired. Understanding these factors is essential for proper diagnosis and treatment of the condition.
Genetic causes
Genetic causes of primary hypogonadism usually involve chromosomal abnormalities or inherited disorders that affect the development and function of the testes.
Klinefelter syndrome
Klinefelter syndrome is the most common genetic cause of primary hypogonadism. It occurs when a man has an extra X chromosome, resulting in a chromosome pattern of 47,XXY. This disorder prevents normal development of the testicles, leading to insufficient testosterone production and, in many cases, problems with fertility due to a low testicular count. sperm.
Other genetic disorders
There are other genetic disorders that can also lead to primary hypogonadism. Some of these include:
- Enzymatic defects in testosterone synthesis, which may affect the metabolic pathways necessary for adequate production of sex hormones.
- Testicular development disorders, which are present from birth and can prevent proper maturation of the testicles.
Acquired causes
Acquired causes include factors that can affect testicular function temporarily or permanently throughout the individual's life.
autoimmune diseases
Autoimmune diseases are conditions in which the immune system attacks the body's own cells. In the case of primary hypogonadism, this can manifest itself through attack on testicular tissue, which decreases testosterone production and can cause permanent damage.
infections and injuries
Infections, especially viral infections such as mumps, can inflame the testicles and result in decreased hormone production. In addition, physical injuries to the testicular area, whether caused by accidents or trauma, can compromise testicular function, leading to primary hypogonadism.
Radiation exposure and surgery
Radiation exposure, such as radiation therapy to treat cancers, can have devastating effects on testicular tissue. Also, certain surgical procedures, such as orchiectomy or surgeries involving the groin area, can result in loss of testicular function and, consequently, low testosterone levels.
Symptoms of primary hypogonadism
Symptoms of primary hypogonadism can vary considerably between men and women, as well as depending on the age at which the condition occurs. The main symptoms associated with this disorder are detailed below.
In males
Decreased sex drive
One of the most common symptoms in men with primary hypogonadism is decreased sexual desire or low libidoThis reduction in interest in sexual activity can be noticeable and affect daily life, creating frustration and problems in interpersonal relationships. A lack of testosterone fundamentally impacts sexual drive, generating significant demotivation.
Erectile dysfunction
Erectile dysfunction is also a common occurrence in these patients. Men may experience difficulty achieving or maintaining an erection, which can lead to anxiety and affect their emotional and psychological health. This problem is due, in part, to low testosterone production, which influences the vascular and nerve function necessary to achieve an erection.

Physical and emotional changes
Changes in the body are a significant consequence of primary hypogonadism. Men may experience:
- Reduction in muscle mass and physical performance, which can make everyday tasks difficult.
- Increase in body fat, often seen in the abdominal area.
- Gynecomastia, which is the development of breast tissue in men.
- Emotional problems such as depression, irritability and lack of concentration, which result from hormonal imbalance.
In women
Changes in the menstrual cycle
Women may experience irregularities in their menstrual cycle. They may experience lighter or absent menstrual periods or even breakthrough bleeding. These changes are the result of hormonal changes affecting ovarian function and estrogen production.
Fertility problems
Primary hypogonadism can also negatively affect female fertility. The lack of adequate hormones can lead to difficulties in conceiving, as ovulation may be compromised. These complications can cause personal and emotional concerns.
Bone loss
Finally, a deficiency in sex hormones increases the risk of osteoporosis in women. Decreased estrogen contributes to decreased bone density, which increases the likelihood of fractures and bone injuries as a woman ages.

Diagnosis of primary hypogonadism
Diagnosing primary hypogonadism involves a comprehensive approach that combines clinical evaluation, hormonal testing, and imaging tests. This process is essential to determine the underlying cause and guide appropriate treatment.
clinical evaluation
Clinical evaluation is the first step in diagnosis. A doctor will perform a complete physical examination, paying special attention to secondary sexual characteristics and other clinical manifestations. Signs such as:
- Testicular atrophy.
- Body hair reduction.
- Changes in muscle mass.
In addition, the doctor will take a detailed medical history, including symptoms such as decreased libido, erectile dysfunction and mood swings. All of this will help establish an appropriate clinical context for follow-up diagnostic tests.
Hormone tests
Hormonal testing is essential to confirm the diagnosis. Blood tests are performed to quantify the levels of various hormones.
Testosterone and other hormone levels
The first step is to measure total testosterone levels, usually done in the morning when levels are usually highest. A testosterone level below 300 ng/dL may indicate primary hypogonadism.
Follicle-stimulating and luteinizing hormones
It is also essential to assess follicle-stimulating hormone (FSH) and luteinizing hormone (LH). In primary hypogonadism, FSH and LH levels are often elevated, while testosterone levels are low. This helps to differentiate between primary and secondary hypogonadism.
imaging tests
In some cases, imaging tests may be necessary to investigate structural abnormalities in the testicles.
Testicular ultrasounds
Testicular ultrasounds are used to assess testicular anatomy and detect possible masses or changes in structure that may be related to hormone production.
Magnetic resonance
MRI can be used in more complex situations, where problems related to adjacent structures or the endocrine system in general are suspected. These tests provide additional information that can be crucial to finalizing the diagnosis.
Treatment of primary hypogonadism
Treatment of primary hypogonadism is aimed at restoring normal levels of testosterone in the body and relieve associated symptoms. Strategies include testosterone replacement therapy and addressing any underlying causes contributing to the condition.
testosterone replacement therapy
Testosterone replacement therapy is the most common approach to treating primary hypogonadism. This treatment aims to increase testosterone levels to normal levels, which can significantly improve the quality of life of patients.
Forms of administration
- injections: They are usually administered every two to four weeks and allow for more direct control of hormone levels.
- Patches: They are placed on the skin and release testosterone constantly throughout the day.
- Topical gels: They are applied to the skin and absorbed, providing a practical and effective way to increase hormonal levels.
- Implants: They are inserted under the skin and release testosterone gradually over several months.
Risks and benefits
The benefits of the therapy include increased libido, improved erectile function, muscle development, and emotional well-being. However, there are also risks that need to be considered, such as:
- Increased risk of prostate cancer.
- Other cardiovascular conditions and related health problems.
- Injection site reactions or skin irritations with patches and gels.
Treatment of female hypogonadism
Treatment for hypogonadism in women may involve hormone therapy to balance sex hormone levels. Although less common, estrogen reduction may suggest appropriate therapy to address symptoms.
Treatments for underlying causes
If primary hypogonadism is due to treatable conditions, it is crucial to address these causes to improve testicular function. Some of these conditions may include:
- Infections requiring antimicrobial treatment.
- Hormonal imbalances that need additional adjustments.
- Autoimmune diseases that require specific medical intervention.
Identifying and treating these conditions can contribute to improved hormonal levels and improved patient quality of life.
Complications associated with primary hypogonadism
Complications of primary hypogonadism can have a significant impact on the physical and mental health of affected individuals. These complications range from reproductive problems to issues related to bone and cardiovascular health.
Infertility
One of the most worrying complications of primary hypogonadism is infertility. Deficiency in sperm production can lead to difficulties in conceiving. In many cases, men may experience a low sperm count or even a complete absence of sperm, further complicating the desire to start a family.
Osteoporosis
A lack of testosterone can also contribute to osteoporosis, a condition characterized by decreased bone density. This increases the risk of bone fractures and injuries. Testosterone plays a crucial role in maintaining bone mass, so a deficiency in it can result in a weakened bone structure. This is especially alarming as people age, as bone resilience naturally reduces.
Cardiovascular problems
Primary hypogonadism has been associated with an increased risk of cardiovascular disease. The relationship between low testosterone levels and heart problems has been demonstrated in several studies, suggesting that hormonal deficiency may influence cardiovascular risk factors. This includes conditions such as hypertension and dyslipidemia, which affect overall heart health.
Psychological impact
Psychological complications are common in men with primary hypogonadism. Symptoms may include depression, anxiety, and irritability. Decreased libido and erectile dysfunction may contribute to low self-esteem and frustration. These emotional problems can affect personal relationships and overall quality of life.
Prevention and management of hypogonadism
Prevention and proper management of hypogonadism are key aspects to improve the quality of life of those affected. Various strategies can be implemented, ranging from lifestyle changes to regular medical follow-up.
Lifestyle and preventive measures
Adopting a healthy lifestyle can significantly contribute to the prevention of hypogonadism. Some recommendations include:
- Balanced diet: Eat a nutrient-rich diet that includes essential vitamins and minerals. Adequate intake of zinc and vitamin D is particularly important for hormonal health.
- Regular exercise: Physical activity not only helps maintain an optimal weight, but also improves hormonal health and overall well-being. Strength and endurance exercises are recommended.
- Stress management: Relaxation techniques such as meditation, yoga or conscious breathing can help reduce stress, which can negatively affect hormone levels.
- Avoid harmful substances: Limiting alcohol consumption and avoiding recreational drug use is essential. Both practices can have an adverse impact on testicular function.
Medical care and regular monitoring
Regular medical follow-up is essential for early detection and proper treatment of hypogonadism. It is important to:
- Perform hormonal checks: Hormone level tests should be done periodically, especially if there is a family history of endocrine disorders.
- Consult with specialists: Endocrine physicians can provide more detailed evaluations and personalized recommendations based on the patient's situation.
- Monitor symptoms: Recording any changes in physical and emotional health is key. This can facilitate diagnosis and adjustment of treatment, if necessary.
Active collaboration between patients and healthcare professionals is essential to optimize the management of hypogonadism and improve the quality of life of those who suffer from it.
