Barrier method is: JIPMER 13
**Core Concept**
The barrier method in contraception refers to the use of physical barriers to prevent sperm from meeting the egg. This involves the placement of a physical barrier between the male and female reproductive organs to prevent fertilization.
**Why the Correct Answer is Right**
The barrier method is a widely used, non-hormonal form of contraception that relies on the principle of preventing sperm from reaching the egg. This is achieved through the use of devices such as condoms, diaphragms, and cervical caps, which create a physical barrier between the male reproductive system and the female reproductive tract.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because barrier methods are distinct from hormonal contraceptives, which work by altering the hormonal balance in the body to prevent ovulation or fertilization.
**Option B:** This option is incorrect because the ring method, also known as the vaginal ring, is a form of hormonal contraception that releases hormones into the bloodstream to prevent ovulation.
**Option C:** This option is incorrect because the injectable method, such as Depo-Provera, is a form of hormonal contraception that works by releasing hormones into the bloodstream to prevent ovulation.
**Option D:** This option is incorrect because the implantable method, such as Implanon, is a form of hormonal contraception that works by releasing hormones into the bloodstream to prevent ovulation.
**Clinical Pearl / High-Yield Fact**
One key point to remember is that barrier methods are a non-hormonal form of contraception, which makes them a good option for individuals who cannot use hormonal contraceptives due to medical reasons or personal preference.
**Correct Answer: B. The ring method**
