Ovulation refers to the time when a woman's eggs are released from the ovaries into the fallopian tubes. It usually begins on the 14th day of a woman's menstrual cycle and lasts about 4-5 days. During this time, a woman's immune system begins to release a chemical called interleukin-1, which promotes the union of eggs and sperm.

However, not all couples need to fertilize during ovulation. If the couple does not want children, fertilization in this case will have no effect. In addition, for couples who want to have children, don’t be afraid if you forget your ovulation date. Because fertilization at other times is also possible to form a fetus.

In short, ovulation is very important for couples who want to have children. However, not all couples need to be fertilized during this period. Don’t be afraid if you forget your ovulation date.
