Very little has been elucidated about sexual interest in female-to-male (FtM) transsexual persons.
To investigate the sexual interest of FtM transsexual persons vs that of men using an eye-tracking system.
The study included 15 men and 13 FtM transsexual subjects who viewed three sexual videos (clip 1: sexy clothed young woman kissing the region of the male genitals covered by underwear; clip 2: naked actor and actress kissing and touching each other; and clip 3: heterosexual intercourse between a naked actor and actress) in which several regions were designated for eye-gaze analysis in each frame. The designation of each region was not visible to the participants.
Visual attention was measured across each designated region according to gaze duration.
For clip 1, there was a statistically significant sex difference in the viewing pattern between men and FtM transsexual subjects. Longest gaze time was for the eyes of the actress in men, whereas it was for non-human regions in FtM transsexual subjects. For clip 2, there also was a statistically significant sex difference. Longest gaze time was for the face of the actress in men, whereas it was for non-human regions in FtM transsexual subjects, and there was a significant difference between regions with longest gaze time. The most apparent difference was in the gaze time for the body of the actor: the percentage of time spent gazing at the body of the actor was 8.35% in FtM transsexual subjects, whereas it was only 0.03% in men. For clip 3, there were no statistically significant differences in viewing patterns between men and FtM transsexual subjects, although longest gaze time was for the face of the actress in men, whereas it was for non-human regions in FtM transsexual subjects.
We suggest that the characteristics of sexual interest of FtM transsexual persons are not the same as those of biological men. Tsujimura A, Kiuchi H, Soda T, et al.

关于女变男（FtM）变性者的性兴趣，目前了解甚少。
使用眼动追踪系统研究FtM变性者与男性的性兴趣。
该研究纳入了15名男性和13名FtM变性者，他们观看了三段性爱视频（视频1：穿着性感的年轻女子亲吻男性生殖器被内裤覆盖的部位；视频2：裸体男演员和女演员亲吻并互相抚摸；视频3：裸体男演员和女演员之间的异性性交），每个视频的每一帧中都指定了几个区域用于眼动注视分析。参与者看不到每个区域的指定情况。
根据注视持续时间测量每个指定区域的视觉注意力。
对于视频1，男性和FtM变性者在观看模式上存在统计学显著的性别差异。男性最长注视时间是女演员的眼睛，而FtM变性者最长注视时间是在非人体区域。对于视频2，同样存在统计学显著的性别差异。男性最长注视时间是女演员的脸，而FtM变性者最长注视时间是在非人体区域，且最长注视时间的区域之间存在显著差异。最明显的差异在于对男演员身体的注视时间：FtM变性者注视男演员身体的时间百分比为8.35%，而男性仅为0.03%。对于视频3，男性和FtM变性者在观看模式上没有统计学显著差异，尽管男性最长注视时间是女演员的脸，而FtM变性者最长注视时间是在非人体区域。
我们认为FtM变性者的性兴趣特征与生理男性不同。辻村A、木内H、曾田T等。性别认同障碍女变男变性者的性兴趣模式与生理男性不同：一项眼动追踪研究。性医学2017；5：e169 - e174。
