Does the Copper T Intrauterine Device (IUD) Interfere With Ovulation?
There is no evidence that The Copper T IUD interferes with the ovulatory process. The primary effect of the IUD is to induce a local inflammatory reaction of the endometrium that’s cellular and humoral components are released into the uterine cavity. Copper IUDs are able to enhance the inflammatory response and reach concentrations in the luminal fluids of the genital tract that are toxic for sperm (spermicidal) and ova (ovaricidal). The viability of eggs are decreased along with affecting their function such that they are not able to be fertilized. This appears to be the major function of the IUD. It is unlikely that if spermatozoa are able to reach the distal segment of the fallopian tube, those that encounter an egg may be in poor condition. Thus the few eggs that are fertilized have little chance for development and the possibility for survival in the altered tubal milieu become worse as they approach the uterine cavity. Chemical pregnancies appear to only occur in .9 percent of pa
