. It is widely believed that the contraceptive effect of the copper IUD is due to its inhibition of the penetration and motility of the spermatozoa in cervical mucus containing copper. This is based on in vitro studies on midcycle cervical mucus incubated with a copper wire. This could not be corroborated by the present investigation of cervical mucus from women using a copper IUD. Cervical mucus collected from these women at the time of ovulation showed no reduction in motility or penetration of the spermatozoa.
