健康的年輕男性其陰莖長度與食指長度相關


  2002年10月3日─男性通常在意其外生殖器的大小是否適當。為確定一項依據以便給病人建議,研究人員測量健康年輕男性的陰莖長度和睾丸大小,並與身體其他器官測量進行比較,其結果發表在9月份的《Urology》。
  
  希臘雅典海軍榮民醫院的Evangelos Spyropoulos 醫師及其同事指出,此對於外生殖器的姿勢缺乏標準公制數據,且缺少廣泛可接受的適當大小的尺度,是在年輕男性擔心其性能力不足下,提出忠告及/或治療的主要困難之處。
  
  對年齡小於40歲,身體正常的男性進行的人體測量參數,包括在非勃起狀態下陰莖尺寸的帶尺測量(總長度,陰莖體長度和陰莖頭長度),陰莖體體積的計算及超音波檢查後睾丸體積的估計。將這些數值和年齡、身高、體重、身體質量指數、腰/臀比及食指長度進行相關分析。
  
  平均睾丸體積為16.9 ± 4.7 cm3;平均總陰莖長度為12.18 ± 1.7 cm;平均陰莖體長度為7.76 ± 1.3 cm;平均陰莖頭長度為4.4 ± 0.4 cm;平均陰莖體體積為46.5 ± 17.2 cm3。儘管總陰莖長度、陰莖體長度和陰莖頭長度與食指長度相關呈顯著性(P<0.05),與陰莖體體積也顯著相關(P<0.001),但是作者們建議要確認這種趨勢還需要進行更多受試者的大規模研究。
  
  在勃起功能障礙的臨床評定這一領域,被建議的數學公式大概會是一個很有用的工具。除食指長度與鬆軟的陰莖,最大伸長的陰莖尺寸有顯著相關之外,年齡和人體測量參數與生殖器的大小並無關係。
  
  

Length of Penis, Index Finger<

By Laurie Barclay, MD

Oct. 3, 2002 — Men are often concerned about the adequacy of their external genitalia. To determine a basis on which to advise patients, investigators measured penile length and testicular volume in healthy young males and compared them with other body measures, as reported in the September issue of Urology.

"The lack of standardized metric data and the absence of widely acceptable criteria on the proper size of the external genitalia poses major difficulties in the counseling and/or treatment of young adult men with worries of sexual inadequacy," write Evangelos Spyropoulos, MD, PhD, and colleagues from the Naval and Veterans Hospital of Athens, Greece.

Somatometric parameters measured in physically normal men younger than age 40 years included tape measurements of penile dimensions in the flaccid-stretched state (total, shaft, glanular lengths), penile shaft volume calculation, and ultrasonographic testicular volume estimation. These values were tested for correlation with age, height, weight, body mass index, waist/hip ratio, and index finger length.

Mean testicular volume was 16.9 ± 4.7 cm3; total penile length, 12.18 ± 1.7 cm; penile shaft length, 7.76 ± 1.3 cm; glanular length, 4.4 ± 0.4 cm; and penile shaft volume, 46.5 ± 17.2 cm3. Although total, shaft, and glanular penile length were significantly correlated to index finger length (P<.05) and to penile shaft volume (P<.001), the authors recommend larger-scale studies involving more subjects to confirm this trend.

"The proposed mathematical formula...presumably could become a useful tool in the field of clinical evaluation of erectile dysfunction," the authors write. "Age and somatometric parameters were not associated with the size of the genitalia, excluding the index finger length, which correlated significantly with the dimensions of the flaccid, maximally stretched, penis."
