Low sperm count (oligospermia) : Causes, symptoms and treatment at Biruni Hospital, Turkey
What is low sperm count (oligospermia)?
Low sperm count, also known medically as oligospermia, refers to a condition in which the number of sperm present in a man’s ejaculate is lower than the normal threshold. According to international fertility guidelines, a healthy sperm count is 15 million sperm per milliliter (mL) or more. When the concentration falls below this level, it may reduce the chances of natural conception.
While many men with low sperm count can still father a child, reduced sperm numbers make it more difficult for sperm to reach and fertilize an egg. This is why oligospermia is one of the most common causes of male infertility worldwide.
Low sperm count can occur on its own or be associated with other sperm abnormalities, such as poor motility (movement),reduced semen volume, or abnormal sperm shape. The condition ranges in severity:
Mild oligospermia: 10–15 million sperm/mL
Moderate oligospermia: 5–10 million sperm/mL
Severe oligospermia: below 5 million sperm/mL
It is important to differentiate low sperm count from azoospermia, a condition in which no sperm at all are found in the semen. Unlike azoospermia, oligospermia often still allows for natural conception or success through fertility treatments.
Early evaluation and proper diagnosis are key steps in identifying the underlying cause and determining the most effective treatment approach.
Symptoms of low sperm count
Low sperm count does not always cause noticeable symptoms, which is why many men only discover the issue during fertility testing. However, in some cases, low sperm count may be associated with certain signs that indicate an underlying reproductive or hormonal problem.
Below are the most common symptoms linked to low sperm count:
Difficulty conceiving
The most common sign of low sperm count is trouble achieving pregnancy after 12 months of regular, unprotected intercourse. A reduced number of sperm lowers the chances of reaching and fertilizing an egg.
Sexual or hormonal symptoms
Some men experience symptoms related to hormonal imbalance or reproductive health issues, such as:
Reduced sexual desire or libido
Erectile difficulties
Ejaculation problems
Decreased facial or body hair
Low energy or chronic fatigue
These symptoms may indicate low testosterone or other hormonal disruptions that affect sperm production.
Pain, swelling, or discomfort in the testicles
Conditions such as varicocele, infection, or inflammation may cause:
Testicular pain
A feeling of heaviness
Noticeable swelling or enlarged veins
These issues can negatively affect sperm quality and count.
Signs of underlying medical conditions
Certain diseases and health issues may indirectly lead to low sperm count, including:
Chronic infections
Thyroid or pituitary disorders
Genetic abnormalities
Previous surgeries or trauma affecting the reproductive organs
This is why a full medical evaluation is often recommended when low sperm count is suspected.
Causes of low sperm count
Low sperm count can result from a combination of medical, lifestyle, and environmental factors. Identifying the underlying cause is crucial for choosing the most effective treatment.
Medical and biological causes
Varicocele: Swollen veins in the scrotum can raise testicular temperature and reduce sperm production.
Infections: Sexually transmitted infections (STIs),epididymitis, or other reproductive infections can affect sperm quality.
Hormonal imbalances: Low testosterone or problems with the pituitary gland can interfere with sperm production.
Genetic conditions: Disorders such as Klinefelter syndrome or chromosomal abnormalities may impair fertility.
Previous surgeries or medical treatments: Operations, radiation, or chemotherapy can temporarily or permanently reduce sperm count.
Lifestyle and environmental factors
Smoking and alcohol consumption: Both are linked to lower sperm quality and quantity.
Drug use: Anabolic steroids and certain recreational drugs can reduce sperm production.
Obesity: Excess body fat can disrupt hormone levels and reduce fertility.
Exposure to heat: Frequent use of hot tubs, saunas, or tight clothing can negatively impact sperm count.
Environmental toxins: Chemicals, heavy metals, and radiation in the workplace or environment may affect reproductive health.
Other contributing factors
Age: Sperm quality can decline gradually with age.
Stress: Chronic stress can affect hormone levels and sperm production.
Nutritional deficiencies: Lack of essential vitamins and minerals, such as zinc and vitamin D, may impair sperm health.
How is low sperm count diagnosed
Diagnosing low sperm count involves a combination of clinical evaluation, laboratory tests, and sometimes imaging studies. Early diagnosis is key to identifying underlying causes and selecting the most effective treatment plan.
Initial evaluation
A fertility specialist typically begins with a detailed medical history and physical examination. The doctor may ask about:
Previous illnesses, surgeries, or injuries affecting the reproductive system
Sexual health and libido
Lifestyle factors, including smoking, alcohol, drug use, and occupation
Family history of infertility or genetic conditions
A thorough evaluation helps determine which tests are needed next.
Semen analysis
The most important test for diagnosing low sperm count is the semen analysis, which evaluates:
Sperm concentration: Number of sperm per milliliter of semen
Motility: How well sperm move
Morphology: Shape and structure of sperm
Volume and consistency of semen
A single abnormal result may not confirm low sperm count, so doctors often recommend multiple tests over several weeks.
Hormonal testing
Blood tests can check hormone levels that influence sperm production, such as:
Testosterone
Follicle-stimulating hormone (FSH)
Luteinizing hormone (LH)
Prolactin
Abnormal hormone levels may indicate a problem with the testes, pituitary gland, or hypothalamus.
Imaging and additional tests
Scrotal ultrasound: Detects varicocele, blockages, or structural abnormalities
Transrectal ultrasound: Checks for ejaculatory duct obstruction
Genetic testing: Recommended when sperm count is extremely low or azoospermia is suspected
Urinalysis: Used in cases of retrograde ejaculation
These tests allow specialists to pinpoint the underlying cause and choose the most appropriate treatment strategy.
