Question 1

What are barrier methods of contraception?

Accepted Answer

Barrier methods of contraception are techniques that physically block sperm from reaching an egg, thereby preventing pregnancy. These methods include items like condoms, sponges, and diaphragms.

Question 2

How do spermicides work?

Accepted Answer

Spermicides are chemical agents that kill sperm or immobilise them, preventing them from fertilising an egg. They are often used in conjunction with other barrier methods for enhanced effectiveness.

Question 3

What are the advantages of using sponges as a barrier method?

Accepted Answer

Sponges are convenient, easy to use, and can be inserted before sexual intercourse. They also provide additional spermicide for extra protection, but their effectiveness may vary depending on individual use.

Question 4

What is the difference between hormonal IUDs and copper IUDs?

Accepted Answer

Hormonal IUDs release hormones to prevent ovulation and thicken cervical mucus, while copper IUDs release copper ions that are toxic to sperm. Each type has different benefits and side effects based on individual health needs.

Question 5

Are barrier methods effective for preventing sexually transmitted infections (STIs)?

Accepted Answer

Some barrier methods, such as condoms, are effective in reducing the risk of STIs, while others, like diaphragms and sponges, primarily prevent pregnancy and do not offer significant protection against infections.
