Answer:

Hi,

The contraceptive implant is a small, flexible rod inserted under a person’s skin that releases hormones to prevent fertilization.

The contraceptive patch is worn on a person’s outer body and releases hormones to prevent the ovaries from releasing eggs.

The contraceptive diaphragm  is a dome-shaped piece of rubber placed inside the vagina before sexual intercourse.

The condom is worn on the penis to block sperms from entering the vagina.

;)
