Correct answer: D

Option (d) is the correct answer as only statements (b) and (d) are correct because the Cu ions which are released suppress the sperm motility and the fertilising capacity of sperms.

Option (a) is incorrect as statement (b) is also a correct statement.

Option (b) is incorrect as IUDs increase the phagocytosis of sperms and IUD's insertion does not require surgical intervention.

Option (c) is incorrect as hormonal IUDs suppress endometrial changes and changes in cervical mucus, thereby making the cervix hostile to the sperms.
