The cervix, the lower part of the uterus that opens into the vagina, undergoes changes throughout the menstrual cycle that can indicate fertility. Checking the cervix for fertility involves assessing its position, firmness, and mucus. A high, soft cervix with clear, stretchy mucus is generally associated with fertility, while a low, firm cervix with thick, sticky mucus may indicate lower fertility.
Checking cervical position and mucus can be a helpful method for identifying fertile periods, particularly for women trying to conceive. It can also provide insights into overall reproductive health and potential underlying issues. Historically, cervical mucus observation has been used as a natural family planning method to avoid or achieve pregnancy.
