The primary function of Bartholin's glands is to secrete a viscous fluid that lubricates the vaginal canal, particularly during sexual arousal. This lubrication reduces friction and enhances comfort during intercourse, thus playing a crucial role in sexual function. Additionally, the fluid produced by these glands may assist in maintaining the pH balance within the vagina, further contributing to the overall health of the reproductive system. In a state of arousal, the glands become engorged with blood and secrete their mucous into the vaginal canal through their ducts. In essence, without the functional capacity of Bartholin's glands, sexual intercourse could become uncomfortable or even painful due to insufficient natural lubrication.
