Question

What is correct about the contraceptive method shown in the diagram below?

• A. It releases Ca ions that suppress sperm motility.
• B. It releases Cu ions that suppress sperm motility.
• C. It is a hormone-releasing IUDs, that make the uterus unsuitable for implantation.
• D. It prevents the entry of sperm in the uterus.

Answer 1

Answer: (B)

IUDs increase phagocytosis of sperms within the uterus and the Cu ions released suppress sperm motility and the fertilizing capacity of sperms. The hormone-releasing IUDs, in addition, make the uterus unsuitable for implantation and the cervix hostile to the sperms ex: Cu T (copper T), Multiload 375 etc.
