Paragard is a WONDERFUL BC method, one that I have used for 5 years.

I cannot use hormones, so an IUD was something I used.

it is shaped like a T.

It is placed WAY up HIGH into your uterus, at the very top.

Copper in the IUD kills sperm. In lab tests, sperms' head exploded when near copper IONS.

The Copper in the IUD kills sperm. The IUD can also prevent implantation, simply because it is a foreign object inside the uterus.

It's MAIN action is to kill sperm, it also increases cervical discharge.
