The reproductive tract consists of the organs and structures responsible for sex and reproduction.

In females, it consists of the ovaries, fallopian tubes, uterus, cervix and vagina.

In males, it consists of the testicles, vas deferens, uethra and penis.

Because the reproductive tract contains cells that would otherwise be attacked by the immune system, it is partially protected from the immune system. STDs take advantage of this weakness by going through long periods of latency in the reproductive organs.
