Sperm Morphology

For couples experiencing challenges with conception, a semen analysis is one of the first diagnostic tests performed. While sperm count and motility are widely discussed, the structural shape of the sperm is equally critical for successful fertilization. If you are reviewing your semen test results, understanding sperm morphology is essential to evaluating your fertility.

This comprehensive guide explains how sperm shape is analyzed under Kruger strict criteria, how abnormal shapes affect fertilization, and the treatment pathways available to support pregnancy.

Kruger Strict Criteria and Semen Health

Sperm morphology refers to the shape and size of sperm. Under Kruger strict criteria, if 4% or more of sperm have a normal oval head and straight tail, the sample is normal. Head, midpiece, or tail abnormalities can hinder natural fertilization. Learn more in our semen analysis report guide.

Analyze Your Sperm Parameters
A comprehensive semen analysis is the foundation of male fertility evaluations. If you want to check your sperm count, motility, or morphology, you can schedule a diagnostic semen analysis at Pravi Global IVF.

Treatment and ICSI

Antioxidant supplements (CoQ10, Zinc) help protect sperm shape. For severe morphology issues, Intracytoplasmic Sperm Injection (ICSI) is the gold standard, bypassing structural barriers by injecting selected healthy sperm directly into the egg. Read more in our ICSI treatment guide.

Conclusion

A low sperm morphology score indicates structural variations, but natural conception is still possible. Our team provides advanced diagnostics. Contact Pravi Global IVF today to schedule your evaluation.
