The ovum is oval in shape, about 20mm in size, and is the largest cell in a woman’s body. It is discharged by the dominant follicle. Only 300-400 eggs are discharged during a woman’s lifetime, one egg is discharged each month, mostly alternating between the left and right ovaries, and a woman has only one, rarely two or more, in a single pregnancy. The egg is received by the fallopian tube and if a sperm passes through it, a fertilized egg is formed in the abdomen of the fallopian tube and then implantation occurs. During ovulation, there is an increase in vaginal discharge and it is thinner. The main reason for this is to facilitate sperm penetration and thus the possibility of conception. In order to ensure the quality of eggs, you need to avoid smoking and drinking, and enhance the intake of nutrients and balanced nutrition.
