Sperm Morphology
The assessment of sperm shape and structure as part of semen analysis to evaluate male fertility potential.
Full Definition
Sperm morphology evaluation involves microscopic examination of sperm structure, including head, midpiece, and tail characteristics. Normal morphology typically requires properly shaped oval heads, intact midpieces, and straight tails. According to WHO criteria, normal morphology should be ≥4% using strict criteria. Poor morphology (teratospermia) may indicate DNA damage, oxidative stress, or other factors affecting fertility. Morphology assessment helps determine appropriate treatment strategies and success predictions for assisted reproduction.
Usage
Usage note: Often reported as percentage of normally shaped sperm.
