Question

IUDs prevent pregnancy by

• A. Inhibiting physiological and morphological uterine changes required for implantation
• B. Increasing phagocytosis of spermatozoa within Uterus
• C. Suppressing motility of sperms as well as their fertilising capacity
• D. All of the above

Answer 1

Answer: (D)

All of the above

Copper-releasing lUDs (CuT, multiload 375) 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 (progestasert, LNG-20), make the uterus unsuitable for implantation and the cervix hostile to the sperms. IUDs are inserted by trained doctors and they are ideal contraceptives for the females.

So, the correct answer is 'All of the above'.
