Has your semen analysis report shown low sperm motility? Are you concerned about how poor sperm movement may affect your chances of becoming a father?
Asthenozoospermia is a condition in which sperm movement is lower than expected. It may make natural conception more difficult, but poor sperm motility does not automatically mean pregnancy is impossible.
At NeoWomans, Pune, Dr. Chaitanya Ganapule can help couples understand their fertility concerns and discuss appropriate evaluation and treatment options based on their individual needs.
Sperm count is measured through a semen analysis.
Asthenozoospermia refers to reduced sperm motility, which means sperm do not move as effectively as expected.
Sperm need to move through the female reproductive tract to reach an egg. Reduced movement may affect their ability to reach and fertilise the egg naturally.
Sperm motility is one part of male fertility. Sperm count, morphology, sperm vitality and the female partner's reproductive health also influence the chances of pregnancy.
According to the World Health Organization’s sixth-edition semen analysis reference values, the lower fifth-percentile reference values are approximately:
These values are reference points, not strict boundaries between fertile and infertile men. A result below these levels does not automatically mean that natural conception is impossible. <Cite refs={[“turn616971search0″,”turn616971search1”]}/>
Your doctor will interpret your semen analysis alongside sperm count, morphology, vitality, medical history and other fertility factors.
Sperm movement is assessed during semen analysis. The report may describe different patterns of motility.
Progressive motility refers to sperm that move forward effectively. When progressive motility is reduced, fewer sperm may be able to travel efficiently towards the egg.
Total motility includes sperm that move progressively and those that move without effective forward progression. A lower total motility result may indicate that a smaller proportion of sperm are moving.
In some cases, most or nearly all sperm may appear immotile. Further evaluation may be needed to determine whether the sperm are alive but not moving or are non-viable. This distinction can affect treatment decisions.
Poor sperm motility may develop due to several medical, lifestyle or environmental factors.
Possible causes include:
Excess oxidative stress may damage sperm cells and affect their movement.
Enlarged veins around the testicles may affect sperm quality in some men.
Certain reproductive tract infections may affect sperm function.
Hormonal problems may interfere with normal reproductive function.
High temperatures around the testicles may affect sperm development.
These may negatively affect reproductive health.
Chemotherapy, radiation and certain medicines may affect sperm production.
Certain medicines, chemotherapy or radiation may affect sperm quality.
Some genetic disorders can affect sperm structure or movement.
Sometimes, the exact cause cannot be identified.
Certain factors may increase the likelihood of reduced sperm motility.
These include:
Having one or more risk factors does not necessarily mean that a man will develop asthenozoospermia. A medical evaluation can help identify relevant concerns.
Asthenozoospermia usually does not cause noticeable symptoms. Many men discover the condition only after undergoing fertility testing.
Possible reasons to seek an evaluation include:
Poor sperm motility cannot be confirmed by looking at semen. Laboratory testing is required to assess sperm movement.
Treatment depends on the underlying cause, the severity of reduced motility, other semen parameters and the pregnancy goals of both partners. There is no single treatment that works for every man with asthenozoospermia. The aim is to identify treatable conditions where possible and determine whether natural conception or assisted reproductive treatment may be suitable.
If an infection or another treatable condition is identified, your doctor may recommend appropriate treatment. The treatment depends on the diagnosis. Antibiotics should only be used when clinically indicated.
If a clinically significant varicocele is identified alongside infertility and abnormal semen parameters, a specialist may discuss whether treatment is appropriate. The decision depends on the examination, reproductive goals and other clinical findings. Improvement in sperm motility or pregnancy outcomes is not guaranteed.
Medicines may be recommended when a specific underlying condition requires treatment. Certain antioxidant supplements are sometimes considered for male fertility, but evidence of their effectiveness varies. Avoid taking fertility medicines, supplements or hormonal products without medical advice. Testosterone therapy can suppress sperm production in men trying to conceive.
IUI may be considered when the overall fertility assessment suggests that it is suitable. The decision depends on factors such as the number of motile sperm available after laboratory processing and the female partner's fertility findings. IUI may not be appropriate in every case of severe asthenozoospermia.
IVF may be considered when natural conception is unlikely or other fertility factors make assisted reproduction appropriate. Eggs and sperm are combined in a laboratory to allow fertilisation. The treatment plan depends on sperm quality, the female partner's age, reproductive health and the couple's fertility goals.
ICSI is a specialised IVF technique in which a single sperm is injected directly into an egg. It may be considered in selected cases of significant male-factor infertility, including severe sperm motility problems. If sperm are immotile, additional assessment may be needed to determine whether viable sperm are available for treatment. ICSI does not guarantee fertilisation, pregnancy or live birth.
Your doctor may recommend lifestyle changes to support general and reproductive health.
These may include:
These measures support general health but cannot guarantee improved sperm motility.
A fertility evaluation may be helpful if:
Your semen analysis shows reduced sperm motility.
You and your partner have been trying to conceive without success.
You have received an abnormal semen analysis result more than once.
You have a history of testicular injury, surgery or infection.
You have a known hormonal or reproductive health condition.
You have experienced unsuccessful fertility treatment.
You want to understand your fertility options before planning a pregnancy.
Both partners should be evaluated when appropriate, as fertility difficulties may involve male factors, female factors or a combination of both.
Diagnosis begins with a semen analysis and a review of your medical and reproductive history.
Your doctor may recommend further investigations depending on the results, symptoms and suspected cause.

Semen analysis is the main test used to assess sperm motility. It measures the proportion of sperm that move and evaluates other parameters, including sperm concentration, morphology and semen volume. If the first result is abnormal, your doctor may recommend a repeat test to confirm the findings.

Your doctor may ask about previous illnesses, medications, lifestyle habits, testicular injuries, surgeries and fertility treatment. This information helps identify possible factors affecting sperm movement.

A physical examination may help identify varicocele, testicular abnormalities or other conditions affecting reproductive health.

Hormone tests may be recommended if a hormonal problem is suspected. Depending on your clinical findings, tests may include FSH, LH and testosterone.

If a large proportion of sperm appear immotile, a vitality test may help determine whether they are alive. This information may be important when discussing suitable fertility treatment options.

In selected cases, your doctor may recommend a scrotal ultrasound, infection-related tests or other investigations. Not every patient needs every test. The investigation plan depends on individual findings.
The treatment process depends on the cause of reduced sperm motility and the option recommended for the couple.
Sperm motility may improve in some men when contributing factors are addressed.
Helpful measures may include:
These measures support general health but cannot guarantee improved sperm motility. If your semen analysis is abnormal, discuss the findings with a qualified healthcare professional instead of relying only on supplements or home remedies.
Not all cases of asthenozoospermia can be prevented, particularly when genetic or medical conditions are involved.
However, certain measures may support reproductive health:
These steps support general health but cannot prevent every cause of poor sperm motility.
The timeline depends on the cause of poor sperm movement and the treatment used.
Sperm development takes approximately three months. Changes following certain treatments or lifestyle adjustments may therefore take several months to appear in a semen analysis.
However, improvement is not guaranteed, and the timeline varies between individuals.
Your doctor can advise when repeat testing is appropriate.
Yes, natural pregnancy may still be possible when sperm motility is reduced.
The chances depend on the degree of reduced motility, sperm count, sperm morphology, sperm vitality and the female partner’s fertility.
Some couples may conceive naturally, while others may benefit from IUI, IVF or ICSI.
A complete assessment of both partners can help determine the most appropriate next steps.
Poor sperm motility may make it more difficult for sperm to reach and fertilise an egg naturally.
However, asthenozoospermia alone cannot determine whether IVF will succeed.
The outcome also depends on sperm vitality, egg quality, age, embryo development and other reproductive factors.
ICSI may be considered in selected cases to help fertilisation. Your fertility specialist can explain the possible benefits, limitations and expected outcomes based on your individual reports.
At NeoWomans, fertility care focuses on understanding the factors that may affect a couple’s ability to conceive.
Your semen analysis is considered alongside your medical history, other semen parameters and relevant fertility findings.
Dr. Chaitanya Ganapule can discuss fertility evaluation and appropriate next steps based on the clinical findings.
You can discuss available treatment options, their limitations and the investigations that may be required before making a decision.
Fertility concerns may involve one or both partners. Evaluating both partners when appropriate supports informed decisions about conception and treatment.
Dr. Chaitanya Ganapule is a gynaecology and fertility specialist at NeoWomans, Pune.
Consult Dr. Chaitanya Ganapule to discuss fertility concerns, understand the evaluation process and explore suitable next steps for couples experiencing difficulty conceiving.
Depending on the findings, a urologist or andrologist may also be needed for a detailed male reproductive health assessment.
Asthenozoospermia is a condition in which sperm movement is lower than expected. It may affect natural conception, but it does not automatically mean pregnancy is impossible.
Possible causes include oxidative stress, varicocele, certain infections, hormonal conditions, lifestyle factors, excessive heat exposure and some medical treatments. Sometimes, no clear cause is identified.
Commonly used WHO reference values place the lower fifth percentile at approximately 42% for total motility and 30% for progressive motility. These values should be interpreted alongside the complete semen analysis and clinical history.
Some underlying causes can be treated, and sperm motility may improve in selected cases. However, there is no single treatment that guarantees normal sperm movement.
Yes, fatherhood may still be possible through natural conception or fertility treatment. The options depend on sperm motility, sperm count, sperm vitality and the fertility assessment of both partners.
Sperm motility may improve in some men when contributing factors are addressed. Healthy lifestyle habits can support reproductive health, but they cannot guarantee an improvement.
Changes may take approximately three months to become apparent because sperm development takes time. The actual timeline depends on the cause and treatment.
Your doctor may recommend semen analysis, a physical examination and hormone tests. Genetic testing or other investigations may be appropriate in selected cases, particularly when sperm concentration is severely reduced.
No. IVF is not necessary for every man with low sperm motility. Depending on the complete fertility assessment, natural conception, IUI, IVF or ICSI may be discussed.
In conventional IVF, eggs and sperm are placed together in a laboratory to allow fertilisation. In ICSI, a single sperm is injected directly into an egg. ICSI may be considered in selected cases of male-factor infertility.
In selected cases, sperm that do not move may still be viable. Additional assessment is needed to determine whether viable sperm are available for ICSI.
No. Reduced sperm motility may lower the chances of natural conception, but it does not by itself establish infertility. Other semen parameters and both partners' reproductive health also matter.
The cost depends on the investigations and treatment required. Consultation, semen analysis, blood tests, medicines, IUI, IVF and ICSI have different costs. Contact NeoWomans for current fees and an individual estimate.
A fertility specialist can help coordinate the couple's fertility evaluation. A urologist or andrologist may also be needed for detailed male reproductive health assessment. At NeoWomans, Dr. Chaitanya Ganapule can discuss fertility concerns and appropriate next steps.
Consider an evaluation if your semen analysis shows low sperm motility or you have concerns about conception. Couples are generally advised to seek an infertility evaluation after 12 months of trying, or after six months when the female partner is aged 35 or older. Earlier assessment may be appropriate when known fertility problems or other risk factors exist.
A low sperm motility report can raise concerns, but it does not tell the whole story about your chances of becoming a parent. Understanding the possible cause and evaluating both partners can help you make informed decisions about your fertility journey. Consult Dr. Chaitanya Ganapule at NeoWomans to discuss fertility concerns, investigations and suitable next steps.
