- DPrevents ovulation by regulating hormone levels
Correct answer
C. Releases copper ions to prevent sperm from fertilizing the egg
Step-by-step solution
These Intra Uterine Devices are presently available as the non-medicated IUDs (e.g., Lippes loop), copper releasing IUDs (CuT, Cu7, Multiload 375) and the hormone releasing IUDs (Progestasert, LNG-20) (Figure 3.2). IUDs increase phagocytosis of sperms within the uterus and the Cu ions released suppress sperm motility and the fertilising capacity of sperms. The hormone releasing IUDs, in addition,make the uterus unsuitable for implantation and the cervix hostile to the sperms.
