Blog on : Understanding Sperm Morphology: What It Means for Fertility


When it comes to male fertility, sperm count and motility often steal the spotlight. However, Sperm Morphology—the size, shape, and structure of sperm—is just as crucial for successful conception. Sperm morphology refers to the size and shape of sperm cells, which play a crucial role in male fertility. It is one of the key parameters analysed in a semen analysis to determine sperm health and the chances of successful fertilisation. Isha Women’s Hospital specialises in diagnosing and treating male infertility under the expert guidance of Dr Chinmay Pataki, the best fertility specialist in the Thane district.

How is Sperm Morphology Measured?

A normal sperm has an oval head, a well-defined midpiece, and a long tail that helps in motility. Sperm with abnormal shapes—such as large or misshapen heads, short or crooked tails, struggle to swim effectively and penetrate the egg, reducing the chances of conception.

Sperm morphology is evaluated under a microscope by experts using strict criteria, such as Kruger’s strict morphology assessment. Typically, a morphology percentage above 4% (based on Kruger’s criteria) is considered within the normal range for fertility.

Causes of Abnormal Sperm Morphology:
Several factors can contribute to poor sperm morphology, including:

  • Genetic Factors – Some men have a hereditary predisposition to abnormal sperm shape.
  • Lifestyle Factors – Smoking, excessive alcohol consumption, drug use, and obesity can negatively impact sperm morphology.
  • Medical Conditions – Varicocele (swollen veins in the scrotum), infections, hormonal imbalances, and high oxidative stress can lead to sperm abnormalities.
  • Environmental Toxins – Exposure to pesticides, chemicals, and radiation can affect sperm development.
Can You Improve Sperm Morphology?
Yes! While some cases of poor sperm morphology are due to genetic factors, lifestyle modifications can significantly improve sperm health. Dr Chinmay Pataki one of the best male infertility experts in Mumbai recommends the following tips to enhance sperm morphology and overall fertility:

ü  Maintain a Healthy Diet – Consume antioxidant-rich foods like fruits, vegetables, nuts, and fish to combat oxidative stress.
ü  Exercise Regularly – Staying active helps regulate hormones and supports reproductive health.
ü  Avoid Smoking and Alcohol – These substances can damage sperm DNA and negatively impact morphology.
ü  Manage Stress – High stress levels can disrupt hormonal balance and reduce sperm quality.
ü  Minimize Heat Exposure – Avoid tight clothing, excessive sauna use, and prolonged laptop use on your lap, as heat can impair sperm production.
