stomach and female reproductive tract
The lower female reproductive tract consists of the vagina, cervix, and uterus. It is where sperm travel to reach the egg for fertilization, and where a fertilized egg implants and grows during pregnancy.
The penis is the organ than delivers semen to the female reproductive tract during sexual intercourse.
The lower end of female reproductive tract in pigs is not very different from humans. The reproductive system is conserved across all mammals.

Fertilization occurs internally, in the female's reproductive tract, specifically in the fallopian tubes, after mating between male and female mountain gorillas. The sperm from the male gorilla travels up the female's reproductive tract to reach the egg for fertilization.
Sperms are not typically considered as antigens in the female reproductive tract because they are recognized as "non-self" by the immune system. The female body has mechanisms in place to prevent an immune response against sperm, as they are necessary for fertilization and reproduction to occur. Additionally, the female reproductive tract has a unique immunological environment that is conducive to sperm survival.
Slightly acidic, all the time, I believe.
The statement is partially true. Pelvic inflammatory disease can cause scarring in the female reproductive tract that can block the passage of gametes or zygotes. It does not affect males.
Sperm cells are able to swim once they have been ejaculated into the female reproductive tract. The environment and chemical cues in the female reproductive tract trigger the sperm cells to become motile and begin swimming towards the egg.
Pelvic inflammatory disease can cause symptoms outside the reproductive tract for a number of reasons. First, because the female reproductive tract communicates freely with the pelvic cavity, symptoms can include inflammation of the peritoneum and other structures outside the uterus, ovaries and tubes. Second, the severe inflammation can cause systemic symptoms like fatigue, fever, and malaise. Lastly, a woman can get referred pain from the pelvis with PID, such as FitzHugh Curtis Syndrome, which consists of right upper quadrant pain with chlamydial PID.
The outmost part of the female reproductive system is the vulva, which includes the external genitalia such as the labia, clitoris, and vaginal opening.
