[Copper in the menstrual and physiological cycle cervical mucus of copper IUD users (author's transl)]. / Le cuivre dans le mucus cervical du cycle menstruel physiologique et chez les porteuses de DIU au cuivre.

PIP: The article studies the concentration of copper in the cervical mucus of users and nonusers of copper IUDs. Of the 170 samples taken 90 were basal, i.e. taken from nonusers, and 80 were taken from users of No-Gravid, Dalkon Shield, Gravigard, Copper T, and Progestasert. Concentration of copper was much higher in IUD wearers than in nonwearers, even after 2 years from insertion, except in wearers of Dalkon Shield and of Progestasert. Copper concentration in wearers of Gravigard and Copper T were lower than concentrations found in wearers of No-Gravid.^ieng

[Motility of spermatozoa in the cervical mucus of copper wire I.U.D. users]. / La motilite des spermatozoides dans le mucus cervical chez les proteuses de D.I.U. au cuivre.

PIP: 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.^ieng
