What Is a Semen Analysis?
A semen analysis measures the health and quality of your sperm. It is typically the primary diagnostic test recommended when assessing male reproductive health.
This comprehensive evaluation determines how effectively your sperm can:
- Navigate and move through the reproductive tract
- Survive the journey toward the egg
- Successfully achieve fertilisation
What Does a Semen Analysis Test?
Sperm Count
The total number of sperm present in your clinical sample.
Motility
Evaluates sperm movement, which is essential for reaching and fertilising an egg.
Morphology
Assesses the shape of the sperm; abnormal structures can impact fertility potential.
Volume & Vitality
Measures the amount of semen produced and the percentage of living sperm cells.
Normal Ranges Explained
| Parameter | Normal Range | What It Means |
|---|---|---|
| Semen Volume | ≥ 1.4 ml | The total amount of semen produced. Low volume may indicate issues with ejaculation or gland function. |
| Sperm Count (Concentration) | ≥ 16 million/ml | commonly referred to as “sperm count.” Lower levels may reduce fertility potential. |
| Total Sperm Number | ≥ 39 million per sample | The total number of sperm in the entire ejaculate, providing a more complete assessment than concentration alone. |
| Total Motility | ≥ 42% | The percentage of sperm that are moving. Adequate movement is essential for sperm to reach the egg. |
| Progressive Motility | ≥ 30% | The proportion of sperm moving actively forward — the most important type for natural conception. |
| Morphology (Normal Forms) | ≥ 4% | The percentage of normally shaped sperm. Abnormal forms may affect the ability to fertilise an egg. |

Who Should Consider a Sperm Test?
A semen analysis provides vital clinical data. Understanding your baseline fertility allows for more informed decision-making in your reproductive journey.
You may benefit from an assessment if:
- You have been trying to conceive for 6–12 months without success
- You are seeking a baseline fertility check before beginning your journey
- You are currently preparing for assisted conception such as IVF or ICSI
- You have clinical concerns regarding hormone levels or lifestyle factors
- You simply require professional peace of mind and clinical clarity
Semen Analysis vs DNA Fragmentation
Standard Semen Analysis
Assesses the primary external health and physical quality of the sperm.
- Checks Sperm Count
- Evaluates Motility (Movement)
- Assesses Morphology (Shape)
- Identifies Volume and Vitality
DNA Fragmentation Testing
Assesses the internal genetic integrity of the sperm, which a standard test cannot detect.
Why this matters:
You can have normal semen results but still face high DNA damage, which can impact:
- Embryo development and IVF success
- The overall risk of miscarriage
What Affects Sperm Quality?
Several lifestyle and environmental factors can impact your clinical results. Improving these areas can significantly enhance reproductive outcomes:
- Smoking & Alcohol
- High Stress Levels
- Poor Sleep Hygiene
- Diet & Nutrition
- Heat Exposure
- Hormonal Balance
Note: Avoid saunas and direct laptop heat on the lap prior to testing.
