Slag during ovulation means that during ovulation, the female reproductive tract may discharge some transparent fluid, also called eggs. Although eggs are a very important component of the female reproductive tract, sometimes eggs may have some quality problems.

Long-term smoking and drinking may affect the structure and function of eggs, causing them to fail to mature and fertilize normally. In addition, obesity and lack of exercise can also increase a woman's risk of developing egg quality problems, such as insufficient number or poor quality eggs.

In addition to lifestyle factors, genetic factors may also have an impact on egg quality. Women also have an increased risk of developing similar problems if their father or other family members have had egg quality problems.

Although egg quality problems may have an impact on a woman's reproductive health, with appropriate lifestyle and dietary habits, as well as reasonable treatment and health care, women still have a chance of having a healthy child.
