Sperm is indeed considered a foreign structure when in the female reproductive system. However, it is not considered an antigen because it does not come into contact with the blood, therefore the antibody process does not happen.
It is because the reproductive tract of female body is covered by a sac where immune cells are very less i.e in negligible quantity so sperm is not recognise as a foreign antigen.
There are far more female wild horses and burros than there are male. Many studies have taken place to find out why.
i wouldn't recomend it. female rabbits can be unpredictable, they can kick their own babies to death for no reason.
Nothing will happen. The female cat, because she is not nor never will be on heat, will often not welcome the male's advances and might even fight him off. There is no chance she will get pregnant. To stop this behaviour it would be advisable to neuter the young male cat.
Female rabbits normally do, if you're putting two female rabbits together it's best if you get two sisters. It's hard to tell until you put them together really, but it's best to put them together while they're still young.
Raccoons destroy many nests of sea turtles and consume the eggs. They may do the same to crocodile and alligator nests if the female leaves them unguarded. Snake eggs may also be taken.

An antigen can be anything from virus to bacteria to a soluble protein from outside or inside a cell. This includes both foreign and self peptides. An antibody that finds an appropriate antigen will bind to it and your B and T cells determine if it's self or not. A processed antigen came from cytosol. A protein will be taken by ubiquitin to a proteosome where it is broken up into small peptides. These peptides will make their way into the endoplasmic reticulum (through TAP) where they are exposed to MHC's.
A pap smear is normally used to check for cervical cancer or precancerous changes on the cervix. A sample of cells is taken from the uterine cervix, the end of the uterus, that protrudes into the vagina.
Some can. Most don't (if taken as prescribed).
No, there is no guarantee that if sperms from Pele taken,fertiled will produce future Pele. Though there is human ignorance over the matter and issue less couples queue before Invitro Fertilization Centres' sperm banks to obtain sperms of famous persons at an astronomical price. However, it may occur l in 100,000 !
Yes you can but, it will take a will for it to come down. it would be best to neuter when its still a puppy
Yes, you can. The procedure to have your appendix taken out does not affect the reproductive organs.
Yes, but in very small amounts. When semen enters the female reproductive tract from the male, the fluid called semen is made from the fluids inside the male's body. So, if he has taken antibiotics, they would show up in the semen. The thing is that it would be such a small amount that it would be undetectable in the female's blood.
Some plants have both male and female reproductive organs. If the plants pollen is used to pollinate itself, it is known as self pollination. If the pollen is taken by a bee for example to another plant, it is known as a cross pollination.
nope she is taken or will be taken by Giuliano Rizzo
