Sperm PR is an indicator in the routine semen test, pointing to the premotile spermatozoa, which contains A-grade and B-grade spermatozoa.
Routine semen examination is one of the common examination methods for men, which can understand male sperm traits, density, total number, and vitality. Among them, PR refers to forward-moving sperm, which are categorized into Grade A sperm and Grade B sperm, with Grade A sperm being sperm that move forward in a fast straight line and Grade B sperm being sperm that move forward in a curved fast line.
If the sum of class A sperm and class B sperm is greater than 50%, it suggests that the sperm are moving normally and can combine with the egg to form a fertilized egg. If the total number of PR is less than 50%, it suggests that the male sperm is not moving at a sufficient rate, thus increasing the chances of infertility in the couple.
If the result of routine semen test is normal, there is no need to be too nervous and you can choose the right time to prepare for pregnancy. If the semen routine test is abnormal and the total number of PR is found to be less than 50%, the patient needs to consult a doctor in time and cooperate with the doctor to carry out standardized treatment to avoid delaying the condition, which is not conducive to diagnosis and treatment.
