Patient's question:
What is the reference value for normal-shaped sperm? Hello expert, could you please ask the expert what the reference value for normal-shaped sperm is?Doctor's answer:
The 3rd edition of the World Health Organization manual requires normal morphology to account for more than 30%; the 4th edition of the World Health Organization manual only requires normal morphology to account for more than 15%; and in the 5th edition of the World Health Organization manual, normal morphology can be as low as 4% or more. It can be seen that the standard for morphology is becoming increasingly strict, and now many people have poor morphology; moreover, only about 200 sperm are usually examined, so you don't need to worry.
