Not a barrier contraceptive among the following is
**Core Concept**
Barrier contraceptives are methods that physically prevent sperm from reaching the egg, thereby preventing fertilization. Examples include condoms, diaphragms, cervical caps, and spermicides. These methods are often used in combination with other forms of contraception to provide added protection.
**Why the Correct Answer is Right**
The correct answer is a method that does not physically prevent sperm from reaching the egg, but rather works by altering the hormonal balance in the body to prevent ovulation. This method is an example of a hormonal contraceptive. Hormonal contraceptives, such as the pill, ring, patch, and IUD, work by releasing hormones that prevent the release of an egg from the ovary (ovulation) and thicken the cervical mucus, making it difficult for sperm to pass through.
