When a couple faces challenges getting pregnant, often after trying for 8 to 12 months, doctors frequently recommend a sperm analysis for the male partner.
This essential test, also known as a semen analysis, is crucial for assessing male fertility and identifying potential issues with sperm health. It helps infertility specialists determine if a man is infertile or if there are specific factors affecting conception.
What is Sperm Analysis?
A sperm analysis is a laboratory test conducted on a male’s gametes (sperm) to evaluate their health and viability. The test thoroughly examines several key semen parameters, including:
- The number of sperm discharged (sperm count or sperm concentration).
- The shape of the sperm (morphology).
- The movement of the sperm (motility).
- Other important factors like semen volume, pH levels, and the presence of white blood cells.
This test is commonly performed to assess fertility, but it can also confirm the success of a vasectomy by checking for the absence of sperm.
The Easiest Way to Read Your Sperm Analysis Report
Once your sperm analysis is complete, you usually receive the report within 24 hours to one week. To understand it easily, focus on the following main factors, which are critical indicators of sperm health:
Key Parameters and Normal Results:
Here’s a table summarizing the normal ranges for various parameters you’ll find in your semen analysis report, based on recommendations from sources like the World Health Organization (WHO):
| Parameter | Normal Range | Description & Significance |
| Semen Volume | 1.5 mL or more (typically up to 7.6 mL) | This is the total amount of fluid collected in your sample. Low semen volume (less than 2 mL or 1.5 mL) could mean there aren’t enough sperm to fertilize an egg, or it could be due to issues like incomplete collection, frequent sexual intercourse, or a blockage in the ejaculatory ducts. Very high volume can mean sperm are diluted. |
| pH Level | 7.2 to 8.0 | This indicates the acidity or alkalinity of the semen. A pH higher than 8.0 often suggests an infection. A pH less than 7.0 can point to a blockage in the male’s ejaculatory ducts or a contaminated sample. An abnormal pH level can negatively affect how sperm function. |
| Sperm Count / Concentration | 15 million per mL or more (up to 259 million/mL) | This is the total number of sperm present in each milliliter of your semen. A count less than 15 million per mL is considered low and is called oligospermia. If no sperm are present, it’s called azoospermia. A lower count can make conception more difficult, potentially indicating that the testicles aren’t producing enough sperm or that sperm are blocked. |
| Sperm Motility | 40% or more total moving sperm, with at least 32% progressive motility | Motility measures how well sperm move. Progressive motility refers to sperm moving quickly and forward, which is crucial for reaching and fertilizing an egg. More than 50% of sperm should typically show normal movement one hour after ejaculation for a good chance of pregnancy. Low motility (called asthenozoospermia) means sperm struggle to move effectively, reducing the chances of conception. |
| Sperm Morphology | 4% or more normal shape (up to 48%) | This refers to the size and shape of sperm. Healthy sperm typically have an oval head and an extended tail. Sperm with abnormal shapes (like a bent tail or extra head) have less fertility potential and may struggle to fertilize an egg. A high percentage of abnormally shaped sperm is called teratozoospermia. |
| Liquefaction Time | Within 15-60 minutes | Semen is initially thick and gel-like, needing to become watery (liquefy) for sperm to move freely. If it takes more than 30 minutes to liquefy, it can negatively affect fertility. |
| Vitality | 58% or more live sperm | This measures the percentage of live sperm in the sample. It’s important to differentiate between live but non-motile sperm and dead sperm. |
| White Blood Cells (Leukocytes) | Less than 1 million per mL | A small number is normal, but more than 1 million leukocytes per milliliter is considered abnormal. A high count (called pyospermia) can indicate inflammation or infection, potentially damaging sperm cells and affecting their quality and motility. |
What Abnormal Sperm Results Indicate:
If your semen analysis report shows abnormal results, it means there are factors that might make it harder to achieve pregnancy. Abnormal results don’t always mean complete infertility, but they can reduce the chances of natural conception.
Such results might suggest:
- Infertility.
- An infection.
- Hormonal imbalances.
- Genetic defects.
- Underlying medical conditions, such as diabetes.
- Exposure to radiation.
Your doctor might recommend a second semen analysis after four to six weeks to confirm the findings, as sperm count can fluctuate daily. If abnormalities persist, further tests might be conducted to identify underlying issues.
Normal Sperm Count to Get Pregnant:
For a good chance of achieving pregnancy naturally, a normal sperm count is considered 15 million per mL or more.
The total sperm count per ejaculate should ideally be 39 million or higher. Alongside this, sperm motility should be at least 40% (total motility), and 4% or more of sperm should have a normal shape.
While a lower count may reduce your chances, it doesn’t automatically mean infertility, as other factors and treatments can help.
Signs That Might Indicate a Low Sperm Count:
Signs of a low sperm count are not always obvious, but some symptoms can hint at a problem with fertility. These include:
- Difficulty Conceiving: If you’ve been trying to get pregnant for about a year without success.
- Thin or Watery Semen: Your semen may appear less thick than usual.
- Low Sex Drive: A reduced interest in sexual activity.
- Erectile Dysfunction: Trouble getting or maintaining an erection.
- Pain or Swelling: Discomfort in the testicles or groin area.
- Hormonal Issues: Signs like reduced body hair or weight gain, which could be due to low testosterone levels.
Research also indicates that men with a low sperm count might have a higher percentage of body fat, higher blood pressure, and an increased risk of metabolic syndrome (which can lead to conditions like diabetes and heart disease). If you experience these symptoms, a sperm analysis is a good first step to evaluate your sperm health.

How to Improve Sperm Health and Count Naturally:
Making healthy lifestyle changes can often help improve sperm count and overall sperm health:
- Eat a Healthy Diet: Include foods rich in zinc, vitamin C, vitamin D, and antioxidants, such as nuts, fish, eggs, and fruits.
- Exercise Regularly: Moderate exercise can boost testosterone levels and improve sperm production.
- Stay Hydrated: Drink plenty of water to maintain adequate semen volume.
- Manage Stress: High stress levels can lower sperm count. Try relaxation techniques like meditation or yoga.
- Avoid Smoking & Excessive Alcohol: These substances can reduce sperm quality and motility.
- Maintain a Healthy Weight: Being overweight or obese can lead to lower testosterone levels, affecting sperm count.
- Get Enough Sleep: Poor sleep can disrupt hormone balance, which is vital for sperm production.
- Avoid Heat Exposure: Stay away from hot baths, saunas, and tight underwear, as heat can negatively affect sperm production.
Treatments for Abnormal Sperm Analysis Results:
If lifestyle changes aren’t enough, or if the abnormalities are significant, a fertility specialist or andrologist can recommend various treatments:
- Surgery: May be recommended for issues like varicocele (enlarged veins in the scrotum) or an obstructed vas deferens (tubes that carry sperm).
- Antibiotics: Prescribed if a bacterial infection is affecting sperm count or fertility.
- Medication or Counseling: Used to address sexual intercourse problems, such as early ejaculation or erectile dysfunction.
- Hormone Treatments: If hormonal imbalances (high or low hormone levels) are contributing to infertility, hormone treatments may help.
- Assisted Reproductive Technologies (ART):
- Intrauterine Insemination (IUI): Specially prepared sperm are directly placed into the uterus to increase the chances of fertilization.
- In Vitro Fertilization (IVF): Eggs and sperm are combined in a lab, and the resulting embryos are placed into the uterus. This often involves selecting the strongest and most motile sperm.
- IVF with Intracytoplasmic Sperm Injection (ICSI): A single sperm is injected directly into an egg, often used when there are severe male factor infertility issues.
Final Words:
Understanding your semen analysis report is an important step in your fertility journey. While the terms and numbers can seem overwhelming, focusing on the key parameters will help you grasp your fertility health. If you have concerns about your report, remember that a fertility specialist can provide expert guidance and recommend the best treatment options to help you achieve your dream of parenthood.
Frequently Asked Questions (FAQs):
Sperm morphology refers to the assessment of the sperm’s shape and structure. A normal result typically means that 4% or more of the sperm have a healthy, standard shape.
Semen volume is the total amount of semen produced during ejaculation. A volume of 1.5 milliliters or more is considered normal and is essential for efficiently transporting sperm towards the egg.
Abnormal results do not automatically mean infertility but indicate that further evaluation is needed. It’s crucial to consult a healthcare provider or fertility specialist to understand the implications and discuss potential next steps or treatment options.
To ensure the most accurate assessment of your sperm count and other parameters, you should abstain from ejaculation for 2 to 5 days before the test.
Yes, certain medications can impact sperm production and quality. It is important to inform your doctor about all medications you are currently taking before undergoing the test.
Yes, a sperm motility of 70% is considered good. For optimal fertility, it is crucial that over 50% of sperm demonstrate normal movement one hour after ejaculation. A 70% motility rate indicates a significant proportion of sperm are moving effectively, which is essential for reaching and fertilizing the egg.
To improve the chances of pregnancy, it is ideal for over 50% of sperm to be motile (moving effectively). This ensures that a substantial proportion of the millions of sperm in a sample can swim through the female reproductive tract to reach and fertilize the egg.
Grade 3 sperm motility refers to sperm that move in a linear and more purposeful manner, though with less speed compared to Grade 4, which represents the fastest forward progression. Grade 3 indicates good motility, suggesting the sperm have a strong capability to swim towards the egg for successful fertilization.
