One of the biggest problems I see today is the increasing number of men being diagnosed with teratozoospermia, which simply means that a high proportion of their sperm are reported to have an abnormal shape.
On paper, this sounds alarming.
In reality, many of these diagnoses are based on poorly performed semen analyses.
Unfortunately, this often leads to unnecessary anxiety, incorrect treatment, and expensive IVF procedures that may never have been needed.
What Is Teratozoospermia?
Sperm morphology refers to the shape and structure of sperm.
When a semen report states that a man has teratozoospermia, it means that a large percentage of his sperm have been classified as abnormal in appearance.
Many patients immediately panic.
They assume this means they will be unable to father a child or that they are at risk of having an abnormal baby.
Neither assumption is necessarily true.
Measuring Sperm Morphology Is Much Harder Than It Looks
Many people believe semen analysis is a simple laboratory test.
It isn’t.
Assessing sperm morphology correctly is one of the most technically demanding parts of semen analysis.
The WHO Laboratory Manual for the Examination and Processing of Human Semen provides detailed instructions on how this should be done.
The sperm sample must first be specially stained.
The laboratory technician must then examine the shape of at least 100 individual sperm under high magnification using strict, standardized criteria.
Every sperm has to be evaluated carefully before the final morphology percentage is calculated.
This process is slow.
It requires experience.
It demands attention to detail.
Unfortunately, many laboratories simply don’t do it properly.
The Shortcut That Creates a Misdiagnosis
Instead of following international guidelines, some laboratories take shortcuts.
They examine only a few sperm.
They don’t stain the sample correctly.
They rely on subjective impressions instead of standardized criteria.
Then they issue a report stating that 97%, 98%, or even 99% of the sperm are abnormal.
The patient is labelled as having teratozoospermia.
The laboratory report looks scientific.
The diagnosis often isn’t.
The Domino Effect
Once that report reaches the doctor, a chain of unnecessary events may begin.
The doctor concludes that male-factor infertility is the cause of the couple’s infertility.
The patient is prescribed vitamins, antioxidants, hormones, or other medications that have little evidence of improving sperm morphology.
Or, if the clinic has an IVF laboratory, the couple may be advised to undergo ICSI instead of conventional IVF.
Sometimes they are even pushed directly towards IVF without first questioning whether the laboratory diagnosis itself was correct.
A poor-quality laboratory report can therefore lead to months of unnecessary treatment and considerable emotional and financial expense.
Don’t Accept a Single Number
One of the biggest warning signs is a report that simply states:
“97% abnormal forms.”
That number alone is meaningless.
A good laboratory should be able to explain:
- How the morphology assessment was performed.
- Which staining method was used.
- Which strict criteria were applied.
- What types of abnormalities were observed.
- How many sperm were actually examined.
If the laboratory cannot answer these questions, the quality of the report should be questioned.
Transparency is an important marker of quality.
Always Repeat an Abnormal Result
If your semen analysis reports severe teratozoospermia, don’t panic.
Before making any treatment decisions, repeat the test in a laboratory that has expertise in andrology and follows internationally accepted protocols.
One poorly performed semen analysis should never determine the course of your fertility treatment.
A second opinion may completely change the diagnosis.
Information Therapy Before IVF
Patients often assume that laboratory reports are always correct.
Unfortunately, they are only as reliable as the people and processes behind them.
The smartest question you can ask is not:
“How abnormal is my sperm?”
Instead ask:
“How was this test performed?”
The answer may be far more important than the number on the report.
The Bottom Line
Teratozoospermia is a genuine medical diagnosis—but only when it has been made correctly.
Poor laboratory technique can result in false diagnoses that frighten patients, mislead doctors, and lead to unnecessary medications or IVF procedures.
If your report shows severe abnormalities in sperm morphology, insist on understanding exactly how the diagnosis was made.
And before committing yourself to expensive fertility treatment, repeat the semen analysis in a high-quality laboratory with expertise in sperm morphology assessment.
Remember, the most expensive test is not the one that costs the most.
It is the one that gives the wrong answer.
