What is low sperm count?
Low sperm count or Oligospermia means that the number of sperm in a man’s ejaculate or semen is below normal. A total lack of sperm in the ejaculate is known as Azoospermia. Often semen with a decreased sperm concentration may also show significant abnormalities in sperm morphology and motility.
A sperm count in the ejaculate can vary throughout a man’s life. A healthy sperm count is necessary for fertility. The World Health Organisation (W.H.O) in its latest statement of semen quality (2010), considers a sperm count at 15 million/mL or above as normal sperm count. And anything below that is considered as sperm count low and diagnosed as oligospermia or oligozoospermia.
Low Sperm Count Symptoms
The primary symptom is the inability to have a baby. There can be no other noticeable signs and symptoms. In some cases, a fundamental issue, for example, a hereditary chromosomal abnormality, a hormonal imbalance, dilated testicular veins or a disorder that obstructs the passing of sperm could potentially cause warning signs. The low sperm count signs or oligospermia symptoms include:
- Problems with sexual function, for example, low sex drive or difficulty maintaining an erection (erectile dysfunction).
- Pain swelling or a lump in the testicle area.
- Decreased facial or body hair or other signs of a chromosomal or hormonal imbalance is also one of the low sperm count symptoms.
Low Sperm Count Diagnosis
Most of the cases of oligospermia are detected once the man tries to become a father, and when pregnancy is not achieved in a natural way, even after a year of regular unprotected intercourse, then both the male and female partner must undergo tests to check their fertility conditions.
A gynaecologist or an infertility consultant may order a semen analysis test. The diagnosis of low sperm count or oligospermia is based on low sperm count found in a semen analysis test. However, two tests should be performed to confirm the results. A semen analysis test usually checks at along with pH, etc.:
Main Parameters that are Seen in a Semen Analysis Test
|Ejaculate Volume||( > 1.5 mL)|
|Sperm Concentration||( > 15 million/mL)|
|Total Motility||( > 40%)|
|Progressive Motility||(>= 32%)|
It is more than just a sperm count that matters for a pregnancy to occur, in normal methods of conception as well as assisted methods such as artificial/intrauterine insemination or In vitro fertilisation.
Low sperm count in the ejaculate may at times be accompanied by an abnormality in sperm motility and morphology, and if the motility is poor, the sperm will not be able to reach the oocyte. If the morphology is poor, the sperm would not be able to penetrate the egg. Hence fertilisation is affected.
Types of Low Sperm Count or Oligospermia
When a man has less than 15 million sperm per mL, depending on how low his count is, we distinguish between different levels of severity. The levels are used to diagnose how severe the problem is on a case to case basis, and the treatment would be totally dependent on the level of oligospermia. It is classified in the following groups.
Types of Low Sperm Count
|Types||Sperm concentration in Ejaculate|
|Normozoospermia||>15 million sperm/mL|
|Mild Oligospermia||10 million to 20 million sperm/mL|
|Moderate Oligospermia||5 million to 10 sperm/mL|
|Severe Oligospermia||1 to 5 million sperm/mL|
|Cryptozoospermia||0 to rare sperm, hidden sperms found after centrifugation|
When the number of sperm found in the semen ranges from 10 million to 20 million sperm per millilitre.
When the number of sperm found in the semen ranges from 5 million to 10 million sperm per millilitre. Improvement can be achieved in these cases following proper treatment and a healthy lifestyle for a few months. Semen analysis should be repeated after a few months.
When the number of sperm found in the semen ranges from 1 to 5 million sperm per millilitre. Pregnancy, in this case, can only be achieved by ART (Assisted reproductive technology).
When the number of sperm found in the semen sample after centrifugation is 0 to rare. Pregnancy, in this case, also can only be achieved by ART (Assisted reproductive technology).
When there is no sperm found in the ejaculate, the condition is called azoospermia. Pregnancy, in this case, can only be achieved by ART (Assisted reproductive technology).
Even though pregnancy with oligospermia is possible, still it should be kept in mind that depending on the severity of the case, infertility treatments are available, which allow couples to overcome these obstacles and allow fertilisation to occur successfully.
Low Sperm Count Causes
Most men are completely unaware of their fertility status unless they can make a female pregnant till then they are in the dark. Many reproductive and non-reproductive causes have been reported, but in most cases, the cause remains unexplained because a low sperm count can occur as a temporary alteration. Low sperm count can be caused by a number of medical issues, environmental factors and lifestyle choices. Treatment will be totally dependent on the cause of the problem.
Causes of Low Sperm Count
|Medical Causes||Environmental Causes||Lifestyle Choices|
|Varicocele||Industrial Chemicals||Drug Use|
|Infection||Heavy Metal Exposure||Smoking and Alcohol Consumption|
|Ejaculation Problems||Radiation or X-rays||Stress|
|Tumours||Overheating of Testicles||Weight|
Medical Causes – A low sperm count can be caused by a number of health issues and medical treatment.
- Varicocele – It results in reduced quality of sperm. Enlarged veins in a man’s scrotum disrupt blood flow to the testicle, this causes the temperature in the testicles to increase, and an increase in the temperature can impact sperm production.
- Infections – This interferes with sperm production or sperm health and can cause permanent testicular damage as well. Infections like epididymitis (inflammation of the epididymis), orchitis (inflammation of the testicles) can reduce sperm count in semen. Even sexually transmitted disease can cause low sperm count.
- Ejaculation – Such problems due to some health issues like diabetes, spinal injuries, surgery of the bladder, prostate or urethra can cause retrograde ejaculation that is semen enters the bladder instead of flowing out from the tip of the penis.
- Tumours – Surgery, radiation or chemotherapy to treat tumours can lower sperm count.
- Hormonal Imbalance – the brain and the testicles produce several hormones that are responsible for ejaculation and sperm production, and a hormonal imbalance may lower sperm count.
- Medications – Some medicines like beta-blockers, antibiotics and blood pressure medications can cause ejaculation problems and reduce sperm count.
- Genetic Defects – Men with a severely low sperm count that is when the count is less than 5 million sperm per millilitre of semen have a higher risk of genetic abnormalities. These may result in structural or functional testicular abnormalities. Only 20-30% of men with severe oligospermia and azoospermia are finally diagnosed to have a specific disorder. Identified genetic causes of low sperm count can be Klinefelter’s syndrome, Y chromosome deletion, cystic fibrosis.
Environmental Causes – Exposure to environmental toxins and chemicals can affect sperm production and function.
- Industrial Chemicals – Extended exposure to benzene, toluene, xylene, herbicides, pesticides, organic solvents, painting materials might lead to low sperm count.
- Heavy Metal Exposure – Exposure to lead or other heavy metals can cause low sperm count.
- Radiation or X-rays – Exposure to radiation can reduce sperm production and function. With high doses of radiation, sperm production can be permanently reduced.
- Overheating of Testicles – An increase in the temperature reduces sperm production and function. Use of hot water tubs, saunas, sitting for long hours, wearing tight clothing increases the temperature in the scrotum, which results in reduced sperm production.
Lifestyle Choices – Other causes of low sperm count, includes one’s lifestyle choices.
- Drug Use – Anabolic steroids that are taken to stimulate muscle strength and growth can cause the testicles to shrink and hence, sperm production decreases. Use of illegal drugs too reduce the number and quality of sperm.
- Smoking and Alcohol Consumption – Men who smoke more than 20 cigarettes in a day tend to have a low sperm count. And excess consumption of alcohol can lower testosterone levels and hence cause decreased sperm production.
- Stress – Severe or prolonged psychological stress might cause hormonal imbalance, which might cause a low sperm count.
- Weight – Obese people can have a low sperm count. Adipose tissues (fat) converts testosterone to oestrogen, and extra oestrogen in a man’s body can negatively impact sperm count and sperm quality. Excessive body fat and low muscle mass keep testosterone levels below normal leading to poor quality of sperm.
Depending on the origin where the alteration in sperm production has occurred, the causes can be categorised under three types.
Causes according to the origin of alteration – sperm production
PRE-TESTICULAR OLIGOZOOSPERMIC CAUSES
(Refers to hormonal imbalance that interferes with sperm production and external factors that have an impact on the body)
TESTICULAR OLIGOZOOSPERMIC CAUSES
(Caused by testicular diseases)
POST-TESTICULAR OLIGOZOOSPERMIC CAUSES
(Refers to ejaculation problems, sperm production function works properly, but problem appears during the time of ejaculation)
|Medical treatment which affects sperm production||Varicocele||Obstruction of the vas-deferens|
|Cannabis and alcohol||Age||Infection such as prostatitis|
|Junk food||Injury to the testicle||Retrograde ejaculation|
|Hypogonadism||Genetic abnormalities||Erectile dysfunction|
Tips to Increase Sperm Count Naturally
When a low sperm count is reported after a complete evaluation of all reports like semen analysis, along with blood work to check hormonal levels, an ultrasound, a physical examination, and a detailed family history, then if the condition is treatable, then it should be corrected before opting for assisted reproductive technology. A doctor might recommend some dietary changes, may suggest some vitamins or medicines, may tell to make some lifestyle changes to improve sperm quality and number. Some of the necessary tips include:
- Taking vitamin supplements regularly and food rich in zinc and folic acid (green leafy vegetables) and antioxidants (berries, other brightly coloured fruits and vegetables)
- Avoiding unhealthy habits like smoking, drinking alcohol and taking illegal drugs because it causes low sperm count and problem in sperm motility. Smoking inhibits sperm production.
- The scrotum should be avoided from exposure to intense temperatures. Few degrees increase in scrotal temperatures can severely affect sperm production. So, wearing tight-fitting underwear should be avoided, and hot tubs and saunas should also be avoided.
- Minimising stress as much as possible. Exercising regularly, relaxing and avoiding stressful situations as much as possible. Studies have linked stress to hormonal imbalance.
- Maintaining a healthy weight. Being overweight or underweight can affect sperm count. Oestrogen and testosterone levels are affected by body mass, and the amount of body fat one has.
- Avoiding steroids as they can cause testicular reduction and infertility.
If sperm count doesn’t increase after this, it is recommended to visit an infertility specialist, he or she might treat you depending on the cause of the underlying condition. Might suggest some medication or suggest assisted reproductive technology for conception.
Low Sperm Count Treatment
Low sperm count is a treatable area in the field of infertility, and thus the oligospermia treatment or low sperm count treatment depends on the cause of the condition. A man who is suffering from varicocele, surgery for oligospermia sperm count is the most common treatment. For low sperm counts due to infections of the urinary or reproductive tract, antibiotics are prescribed to clear the infection. Medication and hormone replacement treatment is used when the cause of low sperm count is related to a hormonal imbalance. If a couple still finds it difficult to get pregnant, then it would be advisable for them to visit an infertility specialist and assisted reproductive technology might be recommended to facilitate conception either by IUI (Intrauterine insemination), IVF (In vitro fertilisation), ICSI (Intracytoplasmic sperm injection) and in cases where no sperm are found in the ejaculate or very low sperm count testicular sperm aspiration procedures are recommended which allow sperm to be suctioned and extracted from the testicles and then to be used in conjunction with IVF.
Even though it takes only one sperm to fertilise an egg, but it takes millions of sperm to increase the chances of that one sperm to find its way to the egg and fertilise it, and thus create an embryo. In a normal sperm count, of the 40-200 million sperm present per mL of the ejaculate, only a few hundred sperm make it to the fallopian tubes. And then one healthy sperm will release an enzyme that will help to penetrate the eggshell.
Men who have low sperm count that is less than 15 million per mL are not considered infertile, but it means it will take a longer time, more finesse and planning for the couple to conceive a healthy child. If natural ways of conception or sperm enhancement fails, there is assisted reproductive technology to achieve pregnancy in such cases.
Low Sperm Count Success Story
Rishi (41) and Ankita (39) were trying to conceive for over a year but without any luck.
We already have a boy who is 7 years old but wanted to extend our family. After a year of trying naturally when Ankita didn’t conceive, we couldn’t get the reason behind it as we already have our own biological son. That there could be issues related to fertility, never crossed our mind. After much thoughts, and a suggestion from a dear friend to visit Medicover Fertility, who had his second issue after 10 years, after his wife was treated for some fertility issues in Medicover, I decided to visit Medicover.
There we met Dr Sweta Gupta (Clinical Director), who listened to our concern patiently. Thereby she suggested some preliminary tests for both of us. Ankita’s test report were all normal, but my semen analysis test showed a low sperm count of 2 million sperm per millilitre. I was devastated. Dr Sweta said not to worry but let’s get to the reason behind my low sperm count. After more tests, ultrasounds, it was found that I had a varicocele which needed to be operated to enhance my sperm count.
As I was detected with severe oligospermia and Ankita’s age was also advancing, the team of doctors present there suggested that during my varicocele surgery a testicular sperm aspiration would be done, and the sperm extracted would be used for ICSI in conjunction with IVF. They also suggested sperm cryopreservation for future use.
And yes, everything went as planned, Ankita conceived in the first cycle itself. The varicocele surgery, the testicular sperm aspiration, the ICSI-IVF, all these nerve-wracking moments are worth when I see the face of my daughter. We are a complete family now. Thank you, Medicover Fertility.

Q – Can a man with low sperm count have a baby?
A – Yes, a man with low sperm count can have a baby, but it might take a longer time to impregnate the female, provided the female does not have any reproductive issues. If natural conception does not happen, then depending on his level of low sperm count, he can opt for assisted reproductive technology.
Q – What is the main cause of low sperm count?
A – A single cause of low sperm count is not identified. Causes of low sperm count can be due to hormonal disorders, illness, injury, an obstruction that prevents the release of sperm in the semen, sexual dysfunction, chronic health problems, genetic causes, lifestyle choices and environmental factors.
Q – Can a low sperm count be treated?
A – Yes, treatment is available, either with medications for hormonal imbalance or infections. And for men with oligospermia who are still unable to have children, assisted reproductive technology might help. In the case of mild oligospermia, they can either conceive naturally or by means of IUI. In severe cases, pregnancy can be achieved by IVF or ICSI-IVF.
Q – Can low sperm count lead to miscarriage?
A – Low sperm count does not cause miscarriage, but a recurrent miscarriage can depend on low sperm quality as well as DNA damage.
Q – How can you tell if a man is infertile?
A – In most cases, there are no signs of infertility. Ejaculation usually happens in these cases without difficulty. The quantity and appearance of the ejaculated semen generally appear normal to the naked eye. Medical tests like a semen analysis test, blood tests to find out hormonal disorder, an ultrasound, a physical examination with a detailed family history is needed to find out if a man is infertile.
Q – What does low sperm count look like?
A – A man suffering from low sperm count may have symptoms like problems with sexual function, erectile dysfunction, swelling or lump in the testicles, decreased facial or body hair growth etc.
Q – What cause low sperm count?
A – Unhealthy lifestyle choices can lead to decreased sperm count like smoking and drinking alcohol. Other causes include prolonged sickness, childhood infections, hormonal problems etc.
