Question

Which of the following is a first-generation Intrauterine Device (IUD)?

• A. Lippes loop
• B. Diaphragms
• C. Vaults
• D. Femidoms

Answer 1

The correct option is A Lippes loop

Intrauterine devices (IUDs) are the contraceptive devices that are inserted inside the uterus. They prevent pregnancy by stopping the sperms from reaching the egg (ovum). There are different types of IUDs, like first-generation IUDs (non – medicated inserts), while the second generation are bioactive devices that liberate Copper ions. Third generation IUDs are hormone-based that release certain hormones like progesterone.
The first-generation (non-medicated) intrauterine devices are Lippes loops, rings etc. Lippes loop does not allow the fertilisation of sperm with egg in the female reproductive system. Lippes loop increases the process of sperm phagocytosis as it attracts macrophages in the uterine cavity.

Diaphragm and vaults are non-medicated barriers that fit in the cervix of the female vagina and prevent the passing of sperm through the cervix.
Femidom which is also known as the female condom or internal condom is a barrier device that is used during sexual intercourse to reduce the probability of pregnancy. During intercourse thin silicone sheath of femidom collects the ejaculated semen and thus chances of contact between sperm and egg reduces.
