Ovulation and non-ovulation days

Ovulation refers to the day in a woman’s menstrual cycle when she releases her eggs. After the egg is released from the ovary, it can only survive for about 1-2 days before being fertilized to form an embryo. Therefore, women are more likely to become pregnant during the ovulation period.

Anovulatory periods, on the other hand, refer to the other days in a woman’s menstrual cycle. The non-ovulatory period usually includes the safety period and the in vitro fertilization period. The safe period refers to the day in a woman's menstrual cycle when the egg will not survive too long after being released, and therefore pregnancy will not occur. In vitro fertilization refers to the combination of sperm and eggs outside a woman's body to achieve pregnancy.

Although non-ovulatory periods are relatively safe, pregnancy can still occur. Therefore, women should understand the characteristics of non-ovulatory periods and take safety measures when possible.

In the female menstrual cycle, in addition to the ovulation period and the non-ovulation period, there are other periods, such as the intermediate period and the stable period in the menstrual cycle. Every woman's cycle is different, so each woman's non-ovulatory period will also be different.

To sum up, understanding the characteristics of the non-ovulatory period and taking appropriate safety measures can help women better protect themselves and avoid the risk of pregnancy.
