  15. 尿道下裂 尿道下裂為陰莖最常見的異常,每300個男性中就有一人尿道外部開口位於龜頭副側面 (陰莖尿道下裂)尿道下裂是因為胎兒睪丸睪固酮產量或此激素受體不適當所致!這些缺陷導致龜頭的外索體不能進行管道化,及泌尿生殖摺不能癒合而造成尿道海綿體不完全!

  21. 小陰莖畸形 陰莖非常小而且幾乎都被陰阜上脂肪垂所隱藏,此症狀是因為胎兒睪丸有問題及伴隨發生的腦下腺機能不足

  22. 想 要 成 功 必 先 自 宮

  23. 具 二 根 者 切 一 即 可

  24. 雙陰莖 這些病症是相當異常的,發生時通常會伴隨膀胱外翻,也有可能會伴隨著尿道異常及無肛門的症狀,兩個陰莖的同時發育會造成陰莖雙裂的問題
