Which organs of the male and female reproductive systems secrete fluids that act on the vagina?

In the female reproductive system, the Bartholin's glands (also known as vestibular glands) secrete fluids that lubricate the vaginal opening. Additionally, the cervix produces mucus that helps maintain a healthy vaginal environment. In the male reproductive system, the prostate gland secretes a fluid that forms part of the semen, which can influence the vaginal environment during intercourse. The seminal vesicles also contribute fluids that nourish and protect sperm.
