This guide is for men who have received a semen analysis report and feel unsure what the results actually mean.
If you are seeing numbers marked in red, or words like low motility, borderline morphology, or immotile sperm, this article will help you understand what matters and what to do next.
At Marylebone Diagnostic Centre, we use research-led diagnostics and a data-driven health approach.
Our goal is not to alarm you, but to explain your results clearly and guide you with evidence-based fertility care.
A semen analysis is not a pass-or-fail test. It is a snapshot of sperm health, based on data. Numbers only become useful when they are interpreted correctly.
Clinically, we often see:
This is why MDC focuses on patterns, not isolated values.
Let’s break these down.
Key markers include:
If these are normal, it tells us the environment is suitable for sperm survival. This is a strong foundation.
Many patients are relieved when they see high numbers here. But fertility is not just about how many sperm you have.
It is about how well they move and function.
Motility measures how sperm move.
There are three main types:
What patients often see

This means sperm are present, but many are not moving effectively.
Clinically, this can affect:
But it does not mean fertility is impossible.
It means this is where data-driven health decisions matter most.
Normal reference:

What matters is not just the number, but:
This is why MDC often pairs morphology findings with DNA fragmentation testing.
Some MDC reports include computer-assisted sperm analysis (CASA).
These values include:
When these numbers are low, sperm often:
This explains why some men have high counts but reduced fertility success. This is exactly where research-led diagnostics adds value.
When we see a pattern of:
It often points to functional sperm issues, not production issues.
Common contributing factors include:
These are modifiable factors in many men.
Why One Semen Test Is Not the Final Answer
Sperm production follows a three-month cycle. Today’s result reflects your health from 10 – 12 weeks ago.
This is why MDC often recommends: Repeat semen analysis, DNA fragmentation testing, Hormone profiling, Lifestyle review This is evidence-based longevity for fertility, not guesswork.
