Spermatozoa has sialic acid coat wich hides the antiden,,, plus the uterine endometrium is immunosuppresive
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.
yours logic is right but here the sperms are not at all considered as antigens see friend whats the meaning for antigen? a foreign paticle which able to generate antibodies is nothing but antigen. here sperm doesn,t involves in antigen-antibody complex because of the lack of antibodys.
They do. As soon as sperm enter the female's body, they are under attack. That's why only a few out of several million sperm actually make it to the egg.
Sal is a female or male name but they consider it a female name but Sally is a female name

Every cell in an individual's body has specific markers so the individual's immune system will recognize it as "self". Anything that doesn't have the proper "self" markers, will be recognized as foreign and trigger an immune response (this is one of the major reason why after organ transplant, people have to be put on immuno-suppressant therapy). Sperm also have these markers, so upon insemination, it's possible for the sperm to be recognized as foreign and killed off. That usually doesn't happen because there are other components in semen that help to suppress the female's immune response (otherwise, conception would be quite rare). If you collect sperm from semen and wash away them other components, they will trigger an immune response because, again, the sperm will have certain markers that label it as foreign. Hope this helps.
No.there is no problem.Because both male and female are unable to produce rhesus antigen and there is no prouction of antibody inside the baby blood.

There are a number of people who consider female ninjas to be hot. This is because they are generally in good shape and take care of their bodies.
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.
