Question
Copper ions released from copper-releasing intrauterine devices (IUD's)
Copper ions released from copper-releasing intrauterine devices (IUD's)
Open in App
Solution
The correct options are
B Make uterus unsuitable for implantation
C Increase phagocytosis of sperms
D Suppress sperm motility
The copper IUDs release copper ions into the cervical mucus and makes it toxic to sperms. They also cause the uterus and fallopian tubes to produce a fluid that contains white blood cells, copper ions, enzymes, and prostaglandins, a combination that is also toxic to sperm. And the presence of the device in the uterus makes it unfavourable for implantation. IUD will not interfere with ovulation.
