If you notice a small, firm object or raised area underneath the skin of someone’s upper arm, it can look unusual at first.
One possible explanation is a contraceptive implant, a small flexible rod placed just beneath the skin of the upper arm to prevent pregnancy.
These implants are designed to be discreet, so once they have healed, they may simply feel like a small rod underneath the skin rather than being clearly visible.
What Is a Contraceptive Implant?
A contraceptive implant is a small, flexible plastic rod that is inserted under the skin of the upper arm by a trained healthcare professional.
It releases a hormone called progestogen, which helps prevent pregnancy primarily by stopping ovulation. It also thickens cervical mucus, making it more difficult for sperm to reach an egg.
Because the implant works continuously, there is no need to remember to take a contraceptive pill every day.
Why Can You Feel It Under the Skin?
The implant is deliberately placed close enough to the surface of the skin that a healthcare professional can locate it.
Depending on the person’s body, the implant may be:
- Easy to feel but barely visible
- Slightly noticeable as a small ridge
- More visible when the arm is positioned in certain ways
- Difficult to see but easy to feel with the fingers
The image may therefore look surprising to someone who has never seen or felt a contraceptive implant before.
