Low sperm count, medically known as oligozoospermia, means that the semen contains fewer sperm than the accepted reference level. It is one of the factors that can affect a man’s ability to conceive naturally. However, a low sperm count does not automatically mean infertility. Pregnancy may still be possible depending on sperm motility, morphology, the female partner’s fertility, the couple’s age and other reproductive factors.
If you and your partner have been trying to conceive and a semen report shows a low sperm count, the next step is usually to understand why the count is low and whether treatment can improve the chances of conception.
What Is Considered a Low Sperm Count?
Sperm count is evaluated through a semen analysis, which measures sperm concentration and other important semen parameters.
The WHO-based reference value commonly used in clinical practice is around 15 million sperm per millilitre of semen, with a total sperm number of around 39 million per ejaculate in the 2010 reference framework. More recent WHO guidance emphasizes that semen parameters should be interpreted together rather than using a single number to label someone fertile or infertile.
A semen report may assess:
- Sperm concentration
- Total sperm number
- Sperm motility
- Progressive motility
- Sperm morphology
- Semen volume
- Sperm vitality
This is important because sperm count is only one part of male fertility. For example, a man may have a relatively low sperm concentration but still have enough progressively motile sperm to achieve pregnancy. Similarly, a normal sperm count does not always guarantee fertility if motility, morphology or other reproductive factors are affected.
What Causes Low Sperm Count?
There is no single cause of low sperm count. It can result from problems affecting sperm production, sperm transport, hormones, lifestyle or the reproductive system.
Common causes include:
1. Hormonal Problems
The brain, pituitary gland and testes work together to regulate sperm production. Problems involving hormones such as FSH, LH and testosterone can interfere with this process.
Hormonal evaluation may be recommended when semen results are significantly abnormal or when symptoms suggest an endocrine problem.
2. Varicocele
A varicocele is an enlargement of veins around the testicle. In some men, it can affect testicular temperature and sperm production.
If a varicocele is suspected, a physical examination and further assessment may be recommended.
3. Infections
Certain infections affecting the reproductive system may interfere with sperm production or sperm transport.
4. Previous Testicular Problems or Surgery
A history of undescended testicles, testicular injury, torsion or certain surgeries can sometimes affect sperm production.
5. Genetic Factors
Some genetic conditions can interfere with sperm production and may be considered when sperm counts are extremely low or sperm are absent.
6. Certain Medications or Treatments
Some medications and treatments, including chemotherapy, can affect sperm production. Men should discuss regular medications and previous treatments with their doctor rather than stopping medicines on their own.
7. Lifestyle Factors
- Smoking, excessive alcohol consumption, obesity, poor sleep, prolonged heat exposure and lack of physical activity may negatively affect reproductive health in some men.
- Improving overall health can be an important part of fertility care, although lifestyle changes cannot correct every medical cause of low sperm production.
Are There Symptoms of Low Sperm Count?
In many cases, low sperm count does not cause noticeable symptoms.
- A man may have normal sexual desire, erections and ejaculation but still have a low sperm count.
- The problem may only become apparent when a couple has difficulty conceiving.
Some men may have symptoms related to an underlying cause, such as:
- Reduced sexual desire
- Erectile difficulties
- Testicular pain or swelling
- A lump or enlarged veins around the testicle
- Hormonal symptoms
- Reduced facial or body hair in certain hormonal conditions
Because low sperm count is often silent, semen analysis is an important part of evaluating male fertility.
How Is Low Sperm Count Diagnosed?
- The primary test is a semen analysis.
- The sample is examined in a laboratory to assess sperm concentration, total sperm number, movement and shape, along with other semen characteristics.
- One abnormal report does not necessarily provide the complete picture. Semen parameters can vary between samples, which is why your fertility specialist may recommend repeating the test when appropriate.
A complete evaluation may include:
Medical and Fertility History
Your doctor may ask about:
- How long you have been trying to conceive
- Previous pregnancies
- Previous fertility treatments
- Medical conditions
- Previous surgeries
- Medications
- Lifestyle factors
- Sexual and reproductive history
Physical Examination
A physical examination can help identify conditions such as varicocele or other abnormalities of the reproductive system.
Hormonal Tests
Depending on the semen results and clinical findings, tests such as FSH and testosterone may be recommended. Additional hormonal testing may be considered when clinically appropriate.
Further Male-Fertility Evaluation
Men with significantly abnormal semen parameters may require evaluation by a fertility specialist, urologist or andrologist, depending on the suspected cause.
Can Low Sperm Count Be Treated?
Yes, in many cases the underlying cause can be treated or managed.
Treatment depends on why the sperm count is low.
Possible approaches include:
- Treating an underlying infection
- Correcting certain hormonal problems
- Addressing a varicocele when clinically indicated
- Reviewing medications that may affect fertility
- Improving lifestyle and metabolic health
- Treating specific reproductive conditions
- Using assisted reproductive techniques when necessary
There is no single medicine or supplement that works for every man with low sperm count.
The treatment should therefore be based on the cause and the complete fertility evaluation, rather than the sperm count alone.
Can You Get Pregnant With Low Sperm Count?
Yes, pregnancy can still be possible with a low sperm count.
The chances depend on several factors, including:
- Sperm concentration
- Progressive motility
- Sperm morphology
- Total motile sperm count
- Female partner’s age and fertility
- Duration of infertility
- Whether there are additional fertility problems
For some couples, natural conception may still be possible. In other situations, fertility treatments such as IUI, IVF or ICSI may be considered.
ICSI, or intracytoplasmic sperm injection, involves injecting a single sperm directly into an egg during an IVF cycle. It may be considered in selected cases of significant male-factor infertility.
The appropriate treatment should be decided after evaluating both partners, rather than focusing only on the man’s semen report.
When Should You See a Fertility Specialist?
Consider a fertility consultation if:
- You have been trying to conceive without success.
- A semen analysis shows an abnormal sperm count.
- The sperm count is very low or sperm are absent.
- There is a history of testicular surgery or injury.
- You have symptoms suggesting hormonal or reproductive problems.
- You have previously undergone fertility treatment without success.
- You are concerned about male fertility before trying to conceive.
Early evaluation can help identify potentially treatable causes and avoid unnecessary delays.
Low Sperm Count Does Not Always Mean Infertility
One of the most important things to understand is that a semen analysis is not a simple pass-or-fail fertility test.
Sperm count, motility, morphology and other parameters need to be considered together. Male fertility evaluation also needs to be considered alongside the female partner’s reproductive health.
Therefore, if your report shows a low sperm count, try not to panic. A fertility specialist can help determine what the result means in your individual situation and whether further testing or treatment is needed.

Frequently Asked Questions
1. What is a low sperm count?
Low sperm count means that the concentration or total number of sperm in an ejaculate is below the relevant reference range. It is also called oligozoospermia.
2. Is low sperm count the same as infertility?
No. Low sperm count can reduce the chances of conception, but it does not automatically mean that natural pregnancy is impossible.
3. Can low sperm count improve?
It can improve in some cases, particularly when an underlying cause can be identified and treated. However, improvement depends on the reason for the low count.
4. Which test confirms low sperm count?
A semen analysis is the main laboratory test used to assess sperm concentration and other semen parameters.
5. Can IVF help with low sperm count?
IVF may be an option for selected couples. When male-factor infertility is significant, ICSI may be considered during IVF to help fertilize the egg using an individual sperm.
6. Should both partners be evaluated?
Yes. Fertility is a couple-based issue, and evaluating both partners helps the specialist identify the most appropriate treatment pathway.
7. Can lifestyle changes increase sperm count?
Healthy lifestyle habits may support reproductive health, but they cannot correct every medical cause of low sperm production. Medical evaluation is important when semen parameters are abnormal.
8. When should I consult a fertility specialist?
If you have an abnormal semen analysis or have been trying to conceive without success, a fertility consultation can help identify the possible cause and appropriate next steps.
