Apadravya (Sanskrit: अपद्रव्य) is the generic name used in Kama Sutra for prostheses to increase the size of penis during intercourse, primarily to satisfy a woman classified as hastini (हस्तिनी, 'she-elephant').

"[1][2] Such definition is supposedly illustrative of palang (crossbar in Iban) and other penis inserts of proto-Malay origins.

Nevertheless, it was Doug Malloy in the 1970s who labelled the vertical glans piercing as "apadravya" and the horizontal one as "ampallang.

After initial healing the piercing can be gradually stretched and larger jewelry can be inserted, reaching sizes above 10 mm in diameter.

Because it passes through the most sensitive part of the penis, the procedure is among the most painful of male genital piercings.

It is generally thought of as the most pleasurable for female sexual partners because, compared to Prince Albert, it reportedly allows stimulation of both the G-spot and A-spot in vaginal intercourse.
