我们的目的是证实在性交过程中拍摄男性和女性生殖器的图像是可行的，并将这项研究与以前的理论和最近的性交过程中的解剖学放射学研究进行比较。磁共振成像被用来研究性交过程中男性和女性生殖器的解剖。一对夫妇在两个姿势和男性射精后进行了三次实验。所获得的图像证实，在传教式的性交中，阴茎到达前穹隆，优先接触阴道前壁。膀胱后壁向前和向上推，子宫向上和向后推。从后入位获得的图像首次显示，阴茎似乎到达后穹隆，优先接触阴道后壁。在这个姿势下，膀胱和子宫被向前推。在每个位置，阴茎与女性生殖器的优先接触是不同的。这些图像有助于更好地理解性交的解剖结构。
Our objective was to confirm that it is feasible to take images of the male and female genitals during coitus and to compare this present study with previous theories and recent radiological studies of the anatomy during sexual intercourse. Magnetic resonance imaging was used to study the anatomy of the male and female genitals during coitus. Three experiments were performed with one couple in two positions and after male ejaculation. The images obtained confirmed that during intercourse in the missionary position, the penis reaches the anterior fornix with preferential contact of the anterior vaginal wall. The posterior bladder wall was pushed forward and upward and the uterus was pushed upward and backward. The images obtained from the rear-entry position showed for the first time that the penis seems to reach the posterior fornix with preferential contact of the posterior vaginal wall. In this position, the bladder and uterus were pushed forward. A different preferential contact of the penis with the female genitals was observed with each position. These images could contribute to a better understanding of the anatomy of sexual intercourse.
