All of the following are Barrier methods, except -

Correct option is D

Ans. (d) Lippes loop
Explanation:
Barrier methods of contraception work by physically preventing sperm from entering the uterus, thus stopping fertilization. Lippes loop is NOT a barrier method; it is an intrauterine contraceptive device (IUCD).
Barrier Methods of Contraception (Prevent Sperm Entry):
✅ (a) Diaphragm → Barrier method
· A dome-shaped rubber or silicone cup inserted into the vagina before intercourse.
· Covers the cervix, preventing sperm from entering the uterus.
· Used with spermicidal cream or gel for higher effectiveness.
✅ (b) Foam Tablet → Barrier method
· A vaginal spermicide that dissolves into foam when placed in the vagina before intercourse.
· Kills sperm, preventing fertilization.
✅ (c) Vaginal Sponge → Barrier method
· A soft, spermicide-impregnated sponge placed over the cervix.
· Blocks sperm entry and releases spermicide to kill sperm before they reach the uterus.
Why is (d) Lippes Loop NOT a Barrier Method?
❌ (d) Lippes Loop → NOT a barrier method (It is an IUCD)
· Lippes Loop is a type of intrauterine contraceptive device (IUCD), not a physical barrier.
· It prevents pregnancy by altering the uterine environment to make implantation difficult.
· Unlike barrier methods, it does not physically block sperm from entering the uterus but works inside the uterus to prevent fertilization and implantation.
