Answer 2

IUD's increases phagocytosis of sperms within the uterus:

Intra Uterine devices or IUD's are devices that are inserted in the uterus of the female through the vagina. The medicated IUD's such as copper releasing IUD's such as CuT, Cu7, Multiload 375 and hormone releasing IUD's such as Progestasert and LNG-20 upon insertion causes phagocytosis and makes the sperm immotile.

Phagocytosis of the sperm :

The hormone released by the IUDs is highly made up of proteins. When the sperm comes in contact with these hormones it engulfs the protein molecule present in the hormone. As these are very hard to get digest it causes damages to the sperms acrosome and in turn leads to death of the sperm. This is called phagocytosis of the sperm.
