Slightly higher echogenicity during ovulation is a common physiological phenomenon that usually occurs between the 14th and 21st days of the menstrual cycle. This phenomenon typically causes a woman's ovaries to produce hyperechoic eggs that sit in the fallopian tubes waiting to be fertilized. However, sometimes these hyperechoic egg cells also accumulate in the ovary for some reasons, forming some slightly hyperechoic echo clusters.

Although slightly hyperechoic echogenic masses may have some impact on fertility, this does not mean that they cannot be treated. Therefore, for women with slightly higher echogenicity, doctors usually take some measures to improve their fertility, including monitoring the size and location of the echogenicity, giving drugs or surgical treatment, etc.

In short, slightly higher echogenicity during ovulation is a relatively common physiological phenomenon and usually does not have a serious impact on women's fertility. However, for those women with slightly higher echogenicity, doctors will often take steps to improve their fertility to ensure they can successfully deliver healthy babies.
