if any foreign particles comes in our body then antibodies are produced. sperm is also a foreign particle..when sperm enter to female part then why the antibodies are not producing at that time
Answers
This is correct that antibodies are produced in our bodies when a particle enters into our body which body cells can't identify and consider as a foreign particle thus antibodies are produced to destroy that particle.
But the case of entry of sperms is a bit different. As we know that whole of the menstrual cycle in a female's body is regulated by hormones estrogen and progesterone,estrogen hormone helps in rupturing of mature graffian follicle to release ova so that after coitus (sexual intercourse) SPERMS CAN COME AND FERTILISE THE OVA and progesterone maintains endometrium as well as mucus is secreted to make way for sperms upto to oviduct or to the ova to fertilise the ova that means whole of the menstrual cycle takes place in a female for the sperms to enter into female's body after coitus and fertilise the ova to form zygote and eventually form the embryo.
So if a process in our body is taking place for a particular substance or particle to come from outside and proceed that forward in that case that particular particle or substance won't be regarded as a harmful foreign particle and there will be no need pf production of antibodies to destroy that particle.
