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.
There are far more female wild horses and burros than there are male. Many studies have taken place to find out why.
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.
Bees don't make pollen, they collect it from the flowers they visit.Bees have concave areas on the tibias of their back legs, surrounded by hairs. These are called pollen baskets or corbiculae, and as the bee forages for nectar, it brushes any pollen from its head and body back to the pollen baskets and packs it in.The pollen is taken back to the hive, where it is stored and used for food. It is a rich protein source.
It is generally not recommended to house a baby female rabbit with her mother after her siblings have been weaned. Rabbits can become territorial and may fight for dominance, which can lead to injury. It's best to provide separate living spaces for the mother and her daughter to prevent any potential conflicts.
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.

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.
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.
Some can. Most don't (if taken as prescribed).
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
A nun is a female member of a religious community who has taken vows of poverty, chastity, and obedience.
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.
nope she is taken or will be taken by Giuliano Rizzo
Yes, you can. The procedure to have your appendix taken out does not affect the reproductive organs.
The sperm and egg meet in the fallopian tube, where fertilization typically occurs. The egg is released from the ovary and travels down the fallopian tube, where it may encounter sperm if intercourse has taken place.
