How does GyneFix work

GyneFix is a copper based IUD. These IUD's do not terminate a pregnancy. The primary contraceptive effect of intrauterine contraception is the prevention of fertilisation and implantation by interfering with sperm mobility and survival. The reaction of the intrauterine foreign body with the endometrium activates the release of leukocytes and prostaglandins which act not only in the uterus but also in the oviduct and cervix to impede sperm and egg development.
