Motility of spermatozoa in the cervical mucus of copper wire I.U.D. users

Penetration progression and survival tests of spermatozoa were studied in vitro in the cervical mucus of 18 wearers of copper IUD and in the cervical mucus of 10 control women. The penetration test in IUD wearers was inferior to that of the controls and the progression test and the density of penetration tests revealed greater mobility in the controls mucus than in that of IUD wearers. The test of toxicity of ion copper simply revealed in both groups a reduction in the mobility of spermatozoa. The cervical score was over all inferior in IUD wearers than in controls. (Summary in ENG)
