![]() ![]() ![]() The endocervical epithelium is the main source of mucus secreted in the WGT ( Figure 1). It moisturizes the genital tract mucosa, lubricates the lower genital tract during sexual intercourse, and allows or stops sperm cells from ascending toward the ovule depending on the phase of the menstrual cycle. Mucus of the woman’s genital tract (WGT) plays an essential role in many biological functions. Mucus is a complex viscoelastic gel that forms on the surface of the secretory epithelium and acts as the first line of defense against harmful agents from the outside environment. We also review the current state of knowledge of gel-forming mucins contained in mouse cervicovaginal mucus and the mouse models used to study bacterial vaginosis. This review addresses the current understanding of the cervicovaginal mucus and the cervical mucus plug and their interactions with the microbial communities in both the physiological state and bacterial vaginosis, with a focus on gel-forming mucins. Abnormalities of the cervical mucus plug and bacterial vaginosis are associated with a higher risk of preterm delivery. During pregnancy, the cervical canal is sealed with a cervical mucus plug that prevents the vaginal flora from ascending toward the uterine compartment, which protects the fetus from pathogens. The vaginal epithelium is covered by the cervicovaginal mucus, which is essential to health because of its direct involvement in reproduction and functions as a selective barrier by sheltering the beneficial lactobacilli while helping to clear pathogens. There are no effective prognostic and therapeutic strategies relating to preterm delivery, but uterine infections appear to be a major cause. However, if you pass bright red blood or clots, this could be a sign of a serious problem and you should contact your doctor or go to the hospital immediately.Preterm births are a global health priority that affects 15 million babies every year worldwide. Regardless, if you experience brown, pinkish-brown, or pink discharge during pregnancy in the third-trimester discharge, it is typically not a cause for alarm, but you should still make sure your doctor is aware of these symptoms. Pink or brownish discharge in the third trimester could also be indicative of cervical irritation due to sexual intercourse, a routine pelvic exam by your doctor, cervical polyps, or an infection. It will look like pink or blood-tinged stringy mucus. The mucus plug, which has sealed the cervix throughout the pregnancy, dislodges. Women may notice this pink or brown discharge at 38 weeks of pregnancy or beyond. Small capillaries burst, which becomes a pink or brownish vaginal discharge. ![]() Some women notice a light, bloody mucus that usually indicates that the cervix, the lower section of the uterus, is opening and thinning out. You may notice an increase in vaginal discharge, which is related to the shifting of hormones that help prepare your body for labor. ![]()
