Pre-ovulation egg

Eggs are produced by the ovaries and usually begin forming on the first day of each month in women and peak on the second day. The lifespan of an egg is only one to two days. When a woman enters the ovulation period, the egg begins to enter the uterus through the fallopian tube, preparing to implant and give birth to a new life.

The female menstrual cycle is controlled by the cyclic secretions of the ovaries. The ovaries produce eggs on the first day of each month and release them on the second day. A woman's menstrual cycle is usually divided into two phases: a safe period and a dangerous period. The safe period refers to the one to two weeks after the egg is released, during which women will not be affected by sperm, but the dangerous period starts on the 13th day of the menstrual cycle and lasts until the 19th day of the menstrual cycle. During this time, a woman is susceptible to the influence of sperm and therefore more likely to become pregnant.

Egg quality is crucial to women's fertility. A healthy egg usually goes through a series of tests and evaluations to ensure its quality meets requirements. For example, the doctor may check the egg's viability, maturity, and chromosome number and structure.

In addition to fertility, egg health is related to many other factors. For example, long-term smoking and drinking may affect egg quality and viability. Having certain medical conditions, such as cardiovascular disease, diabetes, and obesity, may also increase a woman's risk of developing egg quality problems.

Understanding the life cycle and role of the egg is critical to women's health and fertility. Women should pay attention to maintaining a healthy lifestyle in their daily lives to ensure that they have healthy, mature eggs and successfully welcome the arrival of new life.
