內陰動脈
（重定向自阴蒂背动脉）
內陰動脈（Arteria pudenda interna）源自於內髂動脈，為三條陰部動脈的其中一條。內陰動脈負責供養外生殖器的血流。

內陰動脈為內髂動脈前分支的終末分支，在雌性個體身上較雄性細小。
解剖
內陰動脈源自於內髂動脈，並爬經骨盆側壁。並於坐骨大孔的梨形肌下方離開骨盆腔，進入臀部。之後沿著薦棘韌帶，穿過坐骨小孔進入會陰。後與內陰靜脈及陰部神經在會陰管中並行。
分支
內陰動脈擁有以下分支：
| 女性 | 男性 | 描述 |
| 下直腸動脈 | 下直腸動脈 | 供應肛管 |
| 會陰動脈 | 會陰動脈 | 供應會陰淺橫肌 |
| 陰唇後支 | 陰囊後動脈 | - |
| 前庭球動脈 | 陰莖球動脈 | 供應前庭球及陰莖球 |
| 陰蒂背動脈 | 陰莖背動脈 | - |
| 陰蒂深動脈 | 陰莖深動脈 | 至陰蒂海綿體及陰莖海綿體 |
