The fluid in the cervix is called cervical mucus.
Cervical mucus plays a crucial role in female fertility. It is a fluid produced by the cervix, and its characteristics change throughout the menstrual cycle. These changes are directly related to hormone levels, primarily estrogen and progesterone. Understanding these changes can help women track their fertility.
Changes in Cervical Mucus During the Menstrual Cycle
| Phase of Cycle | Cervical Mucus Characteristics | Fertility Indication |
|---|---|---|
| After Period | Little to no mucus, feeling dry. | Least Fertile |
| Pre-Ovulation | Sticky or pasty mucus, white or cloudy. | Low Fertility |
| Ovulation | Wet, slippery, and clear, like egg white. | Most Fertile |
| Post-Ovulation | Less mucus, thicker, or absent. | Decreasing Fertility |

Fertile Cervical Mucus: The most fertile type of cervical mucus is often described as "egg white cervical mucus" (EWCM). This type of discharge is wet and slippery, facilitating sperm transport to the egg during ovulation. The reference mentions, "Wet and slippery cervical mucus indicates fertility. This type of discharge makes it easy for sperm to swim to an egg at ovulation."
-
Non-Fertile Cervical Mucus: In contrast, cervical mucus that is sticky, pasty, or absent is less conducive to sperm movement. After menstruation and after ovulation, the cervix produces little to no mucus.
Importance of Cervical Mucus
Cervical mucus plays several key roles:
- Sperm Transport: Facilitates the movement of sperm through the cervix and into the uterus.
- Sperm Nourishment: Provides nutrients that help keep sperm alive.
- Sperm Protection: Protects sperm from the acidic environment of the vagina.
- Barrier: Acts as a barrier to prevent bacteria and other pathogens from entering the uterus.
