the female immune system does recognize semen as a foreign body that's one of the reasons males produce so many sperm.
Immune system of female does recognizes semen but non selectively (First line of immune defence). That's why male discharge 100 million sperms per ml of semen (Generally, 3-4 ml semen per ejaculate). Only few hundreds of them could successfully go through hostile conditions of female reproductive tract, especially vagina. But as sperms approaches near ovum, they are recognized by fertilizing and antifertilizing mechanism to effect fertilization.
This is because the female's immune system is excluded from the uterus and oviducts - there are no receptors there to determine the spermatozoa are foreign. However, if there is an infection or other insult to the uterus, immune cells may show up and start causing problems.
sperm is not a foreign particle because it is present in their body and contains lot of cells
Sperms are not a disease. Without them we would not exist. In a perfect world women would not get their period and ovulate until they were ready to have a child but it is not a perfect world.
The immune system certainly does recognize germs and other foreign bodies. The immune system will then try to fight them off.
An individuals genetic makeup
Normally, immune cells work to recognize and help destroy foreign invaders like bacteria, viruses, and fungi. In autoimmune disorders, these cells mistakenly recognize various tissues of the body as foreign invaders
Microbes evade the immune system through inhibition of phagocytosis by affecting the receptors that phagocytes use to engulf bacteria or by mimicking host cells so that the immune system does not recognize them as foreign.
There are many parts to the immune system. The thymus are what helps the immune system recognize germs and reject them.
Immune system protects the body from any type of foreign antigen or pathogen which can cause disease. It also protect from particles to cause disease in human body.
1. Your immune system can recognize cells based on the proteins present on the surface of cells. Viruses, bacteria, and other foreign cells are recognized as being different from your own cells and are attacked by your immune system.
Immune cells can detect intracellular pathogens through pattern recognition receptors (PRRs) that recognize specific pathogen-associated molecular patterns (PAMPs). When PRRs on immune cells bind to PAMPs, it triggers a signaling cascade that activates the immune response against the intracellular pathogen. This process helps immune cells detect and respond to the presence of intracellular pathogens.
Nonspecific immune response is the first and second line of defense when a foreign object tries to enter or enter the body. This response will attack anything (specific immune response will only attack certain infections) that it comes in contact with.Parts of nonspecific immune response are: Skin, Mucous membranes, Phagocytic (cells that eat foreign particles) cells, Antimicrobial proteins, and the inflammatory response.Inflammation-APEX
The Immune System is the defense network of the body. The immune system works with specific receptors on specialized cells - detecting foreign bodies and signaling for the immune system to destroy them.
Immunization allows your immune system recognize (enemy) foreign life forms that cause disease, thus allowing your body to defend itself.
The body's immune system is able to distinguish between self and non-self cells through various mechanisms. One such mechanism is the presence of major histocompatibility complex (MHC) molecules on the surface of cells, which helps the immune system recognize self-cells. Non-self cells, such as infected or cancerous cells, may display abnormal proteins or antigens that are recognized as foreign by the immune system, prompting an immune response to attack and eliminate them.
