penis (n.)

1670s, perhaps from French pénis or directly from Latin penis "penis," earlier "tail," from PIE *pes- "penis" (cognates: Sanskrit pasas-, Greek peos, posthe "penis," probably also Old English f?sl "progeny, offspring," Old Norse f?sull, German Fasel "young of animals, brood"). The proper plural is penes. The adjective is penial. In psychological writing, penis envy is attested from 1924.

1. The penis is usually in a flaccid state.

**は常に萎縮した状態にある。

2.For the uncircumcised boy，retract the foreskin of the penis and cleanse.

包皮環切断術をしていない男の子には、**前の包皮を取り除いて洗浄する。

3.Thus in the bull the capacity for erection of the penis precedes the appearance of spermatozoa.
