Which of the following is INCORRECT statement?
A. In IUD’s, released Cu ions increases sperm motility and fertilising capacity of sperms
B. Multiload 375 is medicated IUD
C. Lippes loop is non-medicated IUD
D. LNG-20 is hormones releasing IUD
E. Vault is an IUD.
Choose the correct answer from the options given below
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A & E only
Intra Uterine Devices (IUDs) are contraceptive devices placed in the uterus by a doctor or an expert nurse. They are of three kinds: non-medicated, copper releasing and hormone releasing.
A. In IUD’s, released Cu ions increases sperm motility and fertilising capacity of sperms — An incorrect statement. The copper ions do the opposite: they suppress sperm motility and the fertilising capacity of sperms. That is how a copper IUD prevents conception.
B. Multiload 375 is medicated IUD — A correct statement. Multiload 375 is a copper releasing IUD, like CuT and Cu7. A device that releases a substance is called medicated.
C. Lippes loop is non-medicated IUD — A correct statement. Lippes loop releases nothing. It works only as a device in the uterus.
D. LNG-20 is hormones releasing IUD — A correct statement. LNG-20 and Progestasert release a hormone. They make the uterus unsuitable for implantation and the cervix hostile to sperms.
E. Vault is an IUD. — An incorrect statement. The vault is a barrier method. Like the diaphragm and the cervical cap, it is a rubber cover put over the cervix to stop sperms from entering. It is not placed inside the uterus.
NCERT Extract:
Population Stabilisation and Birth Control – “… Another effective and popular method is the use of Intra Uterine Devices (IUDs). These devices are inserted by doctors or expert nurses in the uterus through vagina. These Intra Uterine Devices are presently available as the non-medicated IUDs (e.g., Lippes loop), copper releasing IUDs (CuT, Cu7, Multiload 375) and the hormone releasing IUDs (Progestasert, LNG-20) (Figure 3.2). IUDs increase phagocytosis of sperms within the uterus and the Cu ions released suppress sperm motility and the fertilising capacity of sperms.”
