The size of the egg released during ovulation is about 20mm and is usually mixed in with the leukorrhea and cannot be recognized at all with the naked eye. The ovulated egg is oval in shape and is about 20mm in size. After the egg is released from the ovary, it slowly swims to the juxtaposition of the fallopian tube and waits for the sperm to combine with it. The life span of an egg is only 1 to 2 days and if it combines with a sperm during this time, then the egg is discharged and is usually mixed in the leukorrhea, which is impossible to recognize with the naked eye. Therefore, we cannot see the egg. Only 300-400 eggs are released from a woman’s body in her lifetime, one egg is released each month, and most of them alternate between the right and left ovaries. Women usually have only one ovulation at a time, rarely two or more. During ovulation, vaginal discharge increases and is thin. The main reason for this is that it facilitates sperm penetration, thus increasing the likelihood of conception. In addition, when a woman ovulates, she may feel pain in one side of the lower abdomen, as well as a mild falling sensation in the anus, egg-white leukorrhea, and in a small number of women, vaginal bleeding.
