测定了５３例男性暴力性性犯罪罪犯血清垂体促性腺激素ＬＨ、ＦＳＨ、血浆甾体类性激素睾酮（Ｔ）、雌二醇（Ｅ＿２）、孕酮（Ｐ）、双氢睾酮（ＤＨＴ）、脱氢表雄酮（ＤＨＡ）、雄烯二酮（Ａ）、１７－羟孕酮（１７－ＯＨＰ）、唾液睾酮（ｓＴ）１０项激素指标和睾丸容积，并以同狱４２例４非性犯罪男性罪犯为对照，发现性犯罪组ＳＴ值比对照组明显增高（Ｐ＜０．００１），Ｅ＿２明显降低（Ｐ＜０．００１），两组间睾丸容积比较无显著性差异。表明男性暴力性性犯罪罪犯体内游离睾酮（ＦＴ）水平升高，Ｅ＿２降低为其性犯罪行为的内分泌学基础。由于两组间ＬＨ、ＦＳＨ无差异，提示男性暴力性性犯罪罪犯可能与垂体一ＴＬＦ睾丸轴的负反馈调节机制异常有关。
The serum levels of pituitary gonadotropic hormone LH, FSH, plasma steroid hormones testosterone (T), estradiol (E2), progesterone (P) and dihydrotestosterone (DHT) were measured in 53 male criminals. 10 Hormone Indices and Testicular Volume of Hyperoxvrenosamine (DHA), Androstenedione (A), 17-OHP and Salivary Testosterone (sT), and 42 Non-sexual Crimes Male criminals as controls, found that ST values of sexual crimes group was significantly higher than that of the control group (P <0.001), E 2 was significantly lower (P <0.001), there was no significant difference in testicular volume between the two groups. It indicates that elevated levels of free testosterone (FT) and decreased E_2 are the endocrinological basis of sexual crimes committed by male violent sexual offenders. Because there was no difference of LH and FSH between the two groups, it is suggested that the male violent sexual offender may be related to the abnormal negative feedback regulation mechanism of the pituitary-TLF testicular axis.
