The IUD affects sperm movement and survival in the uterus (womb) so that they cannot reach the egg to fertilise it. The IUD also changes the lining of the womb (endometrium) so that it is not suitable for pregnancy and prevents an egg – if it does become fertilised – from developing.
Intra Uterine Devices are presently available as (a) Non-medicated lUDs (e.g., Lippes loop). (b) Copper releasing lUDs (e.g., Cu-T, Cu-7, Multiload 375). (c) Hormone releasing IUDs (e.g. progestasert, LNG-20). Mode of Action of Hormonal Contraceptives The hormones releasing IUDs, make the uterus unsuitable for implantation and the cervix hostile to the sperms. Progesterone can also be used as injections and implants (slow release of hormones) to inhibit ovulation.
