Low Sperm Count: Causes, Testing & Next Steps
Low sperm count, also called oligospermia, affects about 15% of men trying to conceive. Testing your sperm count at home or through a lab can provide crucial insights into your fertility health and guide next steps with your doctor.
Quick Facts
- What it is: Fewer than 15 million sperm per milliliter of semen
- Key tests: Semen analysis, sperm concentration, motility assessment
- Who should test: Men trying to conceive for 6+ months, those with risk factors
- Cost: $29-$99 depending on testing method
Understanding Low Sperm Count
Low sperm count means your semen contains fewer sperm than normal during ejaculation. According to the World Health Organization, normal sperm concentration is 15 million per milliliter or higher.
The condition affects approximately one in six couples trying to conceive. Male fertility factors contribute to about half of all infertility cases, making sperm testing an important first step.
Several factors can contribute to low sperm count. Heat exposure, certain medications, infections, hormonal imbalances, and lifestyle factors like smoking or excessive alcohol use may reduce sperm production. Varicoceles (enlarged veins in the scrotum) are another common cause.
Age also plays a role. While men produce sperm throughout their lives, sperm quality and quantity can decline with age, particularly after 40.

Symptoms to Watch For
- Difficulty conceiving after 6-12 months of trying
- Problems with sexual function or low sex drive
- Pain, swelling, or lumps in the testicles
- Decreased facial or body hair
- Signs of hormonal imbalance
- History of prostate, sexual, or scrotal problems
- Previous groin surgery or injury
- Recurrent respiratory infections
Recommended Tests
A comprehensive semen analysis remains the gold standard for evaluating sperm count. This test measures sperm concentration, total count, motility (movement), and morphology (shape). Most fertility specialists recommend collecting samples after 2-7 days of abstinence for accurate results.
At-home sperm count tests offer a convenient screening option. These tests typically measure sperm concentration and can indicate whether your levels fall within normal ranges. However, they don’t provide the complete picture that a full laboratory analysis offers.
Best Testing Services
Several testing services offer reliable sperm count testing with different approaches to meet your needs.
Understanding Your Results
Normal sperm count ranges from 15 million to over 200 million sperm per milliliter. Mild oligospermia means 10-15 million per milliliter, while severe cases involve fewer than 5 million per milliliter.
Your results will also include other important parameters. Progressive motility should be at least 32%, and normal morphology should be 4% or higher using strict criteria.
Remember that sperm count can vary between samples. If your first test shows low numbers, your doctor may recommend repeating the test in 2-3 months, as sperm production takes about 74 days to complete.
Frequently Asked Questions
Can lifestyle changes improve sperm count?
Yes, several lifestyle modifications may help. Maintaining a healthy weight, exercising regularly, avoiding excessive heat, limiting alcohol, and not smoking can all support healthy sperm production. Some studies suggest that antioxidant supplements may also help, though you should discuss this with your doctor first.
How long does it take to see improvements?
Since sperm production takes about 74 days, any changes you make today won’t show up in test results for roughly 2-3 months. This is why doctors often recommend retesting after this timeframe when implementing lifestyle changes or treatments.
Are at-home tests as accurate as lab tests?
At-home tests can provide a useful screening for sperm concentration, but they’re not as comprehensive as laboratory analysis. They typically measure only sperm count, not motility, morphology, or other important factors that affect fertility.
What happens if my sperm count is low?
Low sperm count doesn’t automatically mean infertility. Many men with lower counts can still conceive naturally, though it may take longer. Your doctor can discuss treatment options, which might include lifestyle changes, medications, or assisted reproductive techniques depending on your specific situation.
