The role of sperm is to unite with the egg to form a fertilized egg and to perform the function of reproducing life. Sperm is the substance that reproduces the offspring and without it, the offspring cannot reproduce properly. When a male sperm combines with a female egg, it forms a fertilized egg and gradually develops into an embryo in the female uterus. Nowadays, many men have infertility problems, many of which are caused by poor sperm quality or too little sperm. Couples who have been married for a year and have a normal sex life need to go to the hospital for a medical checkup if they are not pregnant and are not using any contraception. Women need to have their eggs and fallopian tubes checked, while men need to have their sperm quality checked. When patients have abnormal sperm quality problems, they should consult a doctor in time and be treated according to the actual condition under the guidance of professional doctors.
