Release of copper and its effect on functional integrity of human sperms in vitro were assessed following co-incubation of semen with CuT 380A. After 30 min of incubation with semen, release of copper ions from CuT 380A was found to be 9.2 to 40 times higher compared to control incubations with PBS. Sperm function tests, when simultaneously performed following loss of motility in sperms (> 95%)...

The intrauterine device (IUD), primarily in the form of the copper IUD, is used by more than 150 million women around the world, making it the most widely used reversible method of contraception. With a remarkably low failure rate of less than 1 per 100 women in the first year of use, the Copper T-380A is in the top tier of contraceptives in terms of efficacy. Risks of utilization include perfo...

BACKGROUND The appropriate choice of a contraceptive method has been a major issue in reproductive health research. Cu T intrauterine device (Cu T IUD) has been introduced as one of the most effective contraceptive methods in the world, however, the relationship between prior use of Cu T IUD and secondary infertility has not been evaluated in Iran. To examine the association of Cu T-380A IUD an...

En este trabajo se usaron métodos electroquímicos estudiar corrosión acelerada T Cu 380A mucosa uterina una celda película delgada, analizó ataque corrosivo con microscopía electrónica barrido, los productos por EDS, calculó vida media Cu-380A mate...

Three intrauterine devices (IUDs) are available in the United States: the copper T 380A and two levonorgestrel-releasing IUDs, one that releases 20 mcg of levonorgestrel per 24 hours, and one that releases 14 mcg per 24 hours. All are safe and effective methods of contraception that work predominantly by prefertilization mechanisms. The copper T 380A IUD may be placed in nonpregnant women at an...
