Methods of contraception are natural methods, chemical methods, barrier methods, intrauterine methods, oral pills, implants and surgical methods. Intrauterine devices are inserted in the uterus with the help of medical professionals. These prevent sperms from reaching the oviduct. If in case fertilization takes place these also prevent implantation in the womb. These can be non-hormonal or hormonal. Lippes loop, copper T is non-hormonal types. Multiload 375 is also a type of CuT. LNG-20 is hormonal IUD. This is levonorgestrel-releasing IUD that releases progesterone (around 20 micrograms per day) hormone. This makes the endometrial lining thicker and thus makes the sperms non-hostile by inhibiting their motility and function.
