Low Sperm count (oligospermia) - causes, treatment, risk and more

When you are trying to conceive and are having trouble, you might not be aware that you have low sperm count, also known as oligospermia. Test results might indicate that your sperm count is below average. There are treatments for many causes of low sperm count.

What is oligospermia (low sperm count)?

Oligospermia is a term that means you have a low sperm count. One medical definition is that you have fewer than 15 million sperm in 1 milliliter of semen. More than 15 million sperm are typically found in one milliliter of semen.

Besides being known as low sperm count, oligospermia is also called oligozoospermia. A severely low sperm count (fewer than 5 million sperm in 1 milliliter of semen) is also known as severe oligospermia.

What is the difference between oligospermia and azoospermia?

Oligospermia means that you do have a measurable amount of sperm in your semen, but the numbers are lower than the typical numbers. If you have azoospermia, it means there no sperm seen in your semen.

Having a low sperm count is a significant factor in infertility. If, after a year of trying, you have not succeeded in getting pregnant or in getting someone else pregnant, you may be infertile. This means that for at least a year you’ve been having regular sex without using birth control methods.

What are the signs and symptoms of oligospermia?

The main sign or symptom of a low sperm count is the inability to conceive a baby with a partner after one year of unprotected sexual intercourse.

What causes a low sperm count?

There are a variety of things that could cause you to experience oligospermia or other sperm disorders. The list of causes include:

Diseases, including those related to genetics, infection, hormones and obstructions (blockages).
Environmental toxins.
Heat.
Drugs.

Some of the diseases that can cause a low sperm count include:

Genetic disorders like cystic fibrosis and Klinefelter syndrome.
Infections like the mumps and other viral diseases, urinary tract infections, and sexually transmitted infections.
Issues like low testosterone and other hormonal abnormalities. A disorder known as hypogonadism occurs when the sex glands fail to produce enough sex hormones.
Blockages that stop sperm from leaving your body.

Medications and drugs

Both prescribed medications and non-prescription substances can make your sperm count low. There are numerous medication categories that may be relevant. Some of these medications include:

Testosterone.
Methadone.
Nitrofurantoin.
Lamotrigine.
Clomipramine.
Paroxetine.
Prednisone.
Methotrexate.
Finasteride.
Sirolimus

There are many other medications that may affect sperm counts. Check with your healthcare provider or pharmacist if you think your medication may be causing problems. Don’t stop taking prescribed medications on your own without discussing with your healthcare provider.

How is oligospermia diagnosed?

Your healthcare provider will take a medical history and do a physical examination. They may order other tests, including:

Semen analysis and sperm function tests.
Urinalysis to test for retrograde ejaculation (sperm moving backward inside you).
Imaging tests of your reproductive organs, including transrectal and scrotal ultrasounds.
Tests of your endocrine system to measure hormone levels.
Testing for genetic disorders.

How is oligospermia treated?

The cause of the oligospermia will determine the recommended course of treatment from your physician. You may increase your sperm count by stopping medications or behaviors that are contributing to low sperm levels.

Other causes may need other treatments. For instance:

You may need surgery to treat a varicocele or blocked sperm ducts.
Your provider may prescribe hormone supplements.
Your provider may prescribe antibiotics for infections.
Your provider may suggest counseling to deal with issues like erectile dysfunction or premature ejaculation.

There are cases when you won’t be able to increase your sperm count. If you’re trying to conceive, your provider might suggest other ways to assist in reproduction.

How should I take care of myself to make sure my sperm count is the best it can be?

If you have a low sperm count, there are certain things your healthcare provider may suggest that you do. These may include lifestyle changes, such as:

Reach and maintain a weight that's healthy for you by exercising and eating a healthy diet.
Stop smoking and using tobacco products.
Reduce the consumption of beverages that contain alcohol.
Stop the use of marijuana and/or other substances.

You may have heard about vitamin or mineral or herbal supplements that may help. Consult your healthcare provider before trying any of these remedies.

How can I reduce my risk of having a low sperm count?

Adopting a healthy lifestyle with respect to sleep, exercise, diet, and alcohol consumption will benefit you in every aspect, including your sperm count.

How long does oligospermia last?

How long a low sperm count lasts depends on the cause. You may be able to reverse the condition if the cause is something you can stop, like taking certain medications or keeping your testicles too warm.

You may not be able to change some causes of low sperm count, such as one that happens as a result of genetic issues.

Oligospermia isn’t a fatal condition and isn’t likely to interfere with work or school.

When should I see my healthcare provider about a low sperm count?

You probably won’t automatically know that you have a low sperm count. It’s not something that you can feel. The first sign is mostly when you can’t conceive when you’re trying. You’ll probably go to a healthcare provider at that time to see why you and your partner aren’t able to conceive. You’ll find out you have oligospermia because you’re tested.

Ask your provider:

What’s causing the low sperm count?
Are there things I can do to make my sperm count higher?
Is the low sperm count related to a serious condition?
Should I see another type of healthcare provider for additional help?

Our Points In Summary

When you and your partner are attempting to conceive, this could be the first indication that your sperm count is low. If you have been purposefully having unprotected sex for a year or more, you should speak with your healthcare professional. You may still be able to become a parent despite having a low sperm count, which may indicate other medical conditions. Talk with your healthcare provider and answer all their questions honestly. Make sure you are able to obtain the information you require and that you are able to ask the questions you wish to ask.
