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… 

Coitus as revealed by ultrasound in one volunteer couple.

The clitoris and vagina must be seen as an anatomical and functional unit being activated by vaginal penetration during intercourse to explain the pleasurable sensitivity of this anterior vaginal area called the G-spot.

Traumatic rectovaginal fistula after sexual intercourse following a non-consensual anal penetration: a case report and a review of the literature

The case of a 36-year-old woman who presented to a gynecological emergency department with pelvic pain and feces coming from the vagina after non-consensual anal intercourse following consensual penile vaginal penetration is presented.

MRI of female genital and pelvic organs during sexual arousal

Using MRI, specific changes in the female genitalia and pelvic organs with sexual arousal are observed, in both pre- and post-menopausal women, using contrast enhanced magnetic resonance imaging.

Contemporary Review of MRI in Benign Genitourinary Pelvic Medicine: What Every Urologist Should Know

MRI has become an indispensable tool in benign Urology with its applicability in diagnosis, prediction, and prognosis of the disease at the organ level (bladder, prostate, urethra) and beyond (brain).

Anatomy of the clitoris and the female sexual response

The clitoris is the center for orgasmic response and is embryologically homologous to the male penis, and it is necessary to understand the intricate anatomy of the organ to assess the data in this regard.

Optimizing outcomes of vaginal prolapse surgery with and without mesh

Anatomic and functional outcomes of midline fascial plication under continuous digital transrectal control were good and risk factors for anatomic failure were initial size of posterior POP (stage ≥ III) and prior colposuspension.

Anatomic variation and orgasm: Could variations in anatomy explain differences in orgasmic success?

Orgasms are complex phenomena involving psychological, physiological, and anatomic variation, and while these variations predispose people to certain sexual function, future research should explore how to surgically or medically alter these.

Vaginal Laceration and Hemorrhagic Shock during Consensual Sexual Intercourse

It is found that the lacerated sites were located at right posterior fornices in all cases and it is postulate that these vulnerable sites of vaginal laceration may be due to the dextro-rotation characteristics of the uterus and the distensibility of the vagina in this area.



Magnetic Resonance Imaging of Sexual Intercourse: Initial Experience

A preferential contact of the penis in erection with the anterior vaginal wall and the anterior cul-de-sac in the face-to-face sexual position is observed in this initial experience of sexual intercourse under MRI.

Magnetic resonance imaging of male and female genitals during coitus and female sexual arousal

Taking magnetic resonance images of the male and female genitals during coitus is feasible and contributes to understanding of anatomy.

The newer techniques have often confirmed selected features of the original EPOR model but have also shown that the characterisation of the coital changes just by a unitary model is inappropriate and new observations suggest a plurality in the changes that can occur.

Innervation of the human vaginal mucosa as revealed by PGP 9.5 immunohistochemistry.

The more distal areas of the vaginal wall had more nerve fibers compared to the more proximal parts and biopsies from the anterior wall generally were more densely innervated than the posterior wall.

Vaginal erotic sensitivity.

Findings indicate that the vagina of most women has a zone (or zones) of erotic sensitivity whose appropriate stimulation can lead to orgasm; it does not support, however, the particular location and characteristics of the vaginal erogenous zone described by other authors.

Vaginal sensitivity to electric stimuli: Theoretical and practical implications

The study provides data underscoring previous anatomical and clinical research findings regarding the sensitivity of the anterior vaginal wall and the inefficiency of coitus for inducing female orgasm.
