Cervical Mucus
Updated:Cervical mucus is a fluid secreted by glands in the cervix, the lower part of the uterus. This mucus changes in consistency and quantity throughout a person's menstrual cycle, playing a crucial role in reproductive health and fertility. The characteristics of cervical mucus can provide valuable information about a person's fertile window and overall reproductive health.
Additional Information
The consistency and appearance of cervical mucus change due to hormonal fluctuations during the menstrual cycle. Around ovulation, it becomes clear, slippery, and stretchy (often compared to egg whites) to facilitate sperm movement and survival. At other times, it may be thicker, cloudier, or less abundant. Many people use cervical mucus observations as part of fertility awareness methods for either achieving or avoiding pregnancy.
Cervical mucus also serves as a natural barrier against infections, helping to protect the uterus from harmful bacteria. However, changes in its normal characteristics can sometimes indicate infections or other health issues.
