There is lot of secretions in our body from mucous membranes and glands, which have their own function, depending upon the place. Normally, the secretions protect our body by forming a slimy lining over the skin or mucous membrane. It also helps to keep the mucous membrane or skin moist and flexible, for example, sebum secretions in the face, saliva in the mouth, etc. If this secretion becomes very low, everyone will feel dryness and cracked skin which paves way for infection. Likewise, vaginal glands also secrete some secretions to keep the organ moist, flexible and to prevent it from infection by its acidic nature. At ovulation time, the acidic nature of the secretion gets altered to alkali nature by hormones to allow the sperm to survive for fertilization. If not, the sperms will find it difficult to thrive and reach the ovum. Also, secretions of the vagina help in lubrication during the sexual act.
