Q. Cu ions released from copper- releasing Intra Uterine Devices (IUDs)

A) Prevent ovulation
B) Make uterus unsuitable for implantation
C) Increase phagocytosis of sperms
D) Suppress sperm motility
Explanation

[Solution from source] Copper ions released by copper IUDs (CuT, Cu7, Multiload 375) suppress sperm motility and fertilising capacity. Making the uterus unsuitable for implantation is attributed to hormone-releasing IUDs, and increased phagocytosis of sperm is a general effect of IUDs, not of Cu ions specifically. Answer (4).
