The luteal phase and ovulation are two very important periods in the fertility process. They refer to a time when a woman's body undergoes dramatic changes in hormone levels that are critical to pregnancy and childbirth. This article will introduce the basic concepts and importance of these two periods.

The luteal phase refers to the period starting on the 13th day and ending on the 29th day of a woman’s menstrual cycle. During this time, a woman's hormone levels suddenly change and enter the progesterone phase, which is one of the main hormones in the female body. Progesterone promotes uterine contractions and helps the embryo implant. The length of this period determines whether a woman can successfully conceive. Generally speaking, the shorter the luteal phase, the greater the chance of successful pregnancy.

2. Ovulation period

The ovulation period refers to the period starting from the 14th day of a woman’s menstrual cycle and ending on the 21st day. During this time, a woman's eggs are released from the ovaries and travel into the fallopian tubes to await fertilization. The survival time of eggs is usually 1-2 days, so if a woman is fertilized during ovulation, she can give birth within 1-2 days.

3. Importance

1. Help with pregnancy

The luteal phase and ovulation are two very important periods in pregnancy. If a woman is able to fertilize within the ovulation period, she can give birth within 1-2 days, which is a very important advantage for women who want to become pregnant.

2. Help fetal development

A woman's egg waits for fertilization in the fallopian tube. During this time, the woman's uterus and embryo undergo a series of developments. If a woman fertilizes during her ovulation period, it can provide the nutrients the fetus needs and help the fetus develop.

3. Help with childbirth

If a woman is fertilized during ovulation, she can give birth within 1-2 days. this
