Solution

The correct option is A Act as spermicidal gel
Intrauterine devices increase phagocytosis of spermatozoa within the uterus and the Cu ions released by some IUDs suppress motility of sperms as well as their fertilizing capacity. The hormone releasing IUDs, in addition, turns the cervix hostile to spermatozoa and bring changes in the uterus making it unsuitable for implantation. So, the correct answer is 'Act as spermicidal gel'.
