Teratozoospermia: When Sperm Shape Really Matters – Cesar Fertility
Cesar Fertility shared a post on LinkedIn:
“Teratozoospermia: when sperm shape really matters.
The morphology of spermatozoa is a parameter that is often misunderstood… until the arrival of the semen analysis.
And when a result of teratozoospermia appears, concern is frequent, both in men and within the couple. However, its meaning is often more nuanced than we think.
In our new article Cesar Fertility, we explain in a simple and documented way what teratozoospermia is, how it is evaluated and what it really means for fertility.
- Less than 4% of spermatozoa of typical shape (according to Kruger): this is the threshold that defines teratozoospermia.
- This parameter is the result of a careful analysis under a microscope, the spermocytogram, which makes it possible to identify abnormalities of the head, the intermediate piece or the flagellum.
- The causes are varied: lifestyle, varicocele, infections, exposure to heat… but also, more rarely, specific genetic abnormalities (globozoospermia, flagella abnormalities, macrocephaly, etc.).
Important message: teratozoospermia is not inevitable.
Its real impact depends on the overall context: concentration, mobility, migration-survival test, but also on the partner’s assessment.
Appropriate care, sometimes combined with lifestyle changes, can really improve the situation.
This article aims to reassure, inform and provide reliable benchmarks, based on international recommendations (WHO).

And to better understand your results:
Cesar Lab, our WHO-compliant tool, helps you interpret your spermiogram, without ever keeping your medical data.”
Lucile Ferreux, Medical Director at Cesar Fertility, shared Cesar Fertility’s post, adding:
“I am sharing this article on teratozoospermia, frequent and often worrying abnormalities in sperm morphology.
Every year in France, hundreds of thousands of spermiograms are performed. And many men discover a rate of ‘abnormal shapes’, without really knowing what it means.
This article, and the Cesar Fertility website, offer reliable and accessible explanations, to avoid wandering online and better understand your results, between two medical appointments.”
