The volume of the egg is 180 times larger than the volume of the sperm and the length of the egg is nearly three times larger than the length of the sperm. The total length of the sperm is 55-60 micrometers, whereas a normal egg is spherical in shape with a diameter of about 150 micrometers, which leads to the conclusion that the volume of the egg is 180 times larger than the volume of the sperm and the length of the egg is nearly 3 times larger than the length of the sperm. Sperm refers to the mature reproductive cells of the human male, which are produced in the testes, stored and matured in the epididymis, and expelled through the vas deferens and the urethra, in a cycle that takes about 3 months. Under normal circumstances, one follicle grows and matures each month and is discharged from one ovary in turn. The egg cell material in the follicle is discharged along with the follicle, and the cellular components that carry the female reproductive genes are combined with the sperm to form a fertilized egg, which is then fertilized in the uterine cavity. It is recommended that couples who are thinking of getting pregnant should regulate their bodies well before pregnancy, and both of them should take nutrient supplements to improve their physical condition, and pay attention to good living and eating habits, such as not staying up too late, quitting smoking and drinking, and so on. If you have any other questions, it is recommended to consult a professional doctor for guidance.
