Its main function is protect pregnancyBy forming a barrier between the uterine cavity and the vagina, it prevents the ascent of potentially harmful bacteria, fungi, and virusesThe vagina is home to many microorganisms, most of them beneficial, but it is also an entry point for germs that could cause [unclear - possibly "infections" or "problems"]. infections and complications if they reach the uterus.
In addition to being a physical barrier, the mucus plug is a defense physical-chemical and immunologicalIt contains approximately 90% water and 10% of glycoproteins (mucopolysaccharides) that give it that dense texture, in addition to immunoglobulins and other substances that help neutralize microorganisms. Therefore, it is essential that it be kept in good condition throughout the entire pregnancy.
How is the mucus plug formed?
The mucus plug forms in the first weeks of pregnancyapproximately between the fourth and seventh week. At that time, the glands of the cervix begin to produce a thicker and more abundant mucus which accumulates until it blocks the cervical canal.
During a menstrual cycle without pregnancy, the cervical mucus Its appearance changes depending on the phase: it becomes more watery and elastic around ovulation to facilitate the passage of sperm, and more thick and acidic During infertile days, cervical mucus is used to slow its rise and prevent infections. When fertilization occurs and the embryo implants, this mucus gradually transforms into a stable cap that seals the cervix.
