Introduction: Women describe at least two types of orgasms: clitoral and vaginal. However, the differences, if any, are a matter of controversy. In order to clarify the functional anatomy of this sexual pleasure, most frequently achieved through clitoral stimulation, we used sonography with the aim of visualizing the movements of the clitorourethr...

There is general agreement that it is possible to have an orgasm thru the direct simulation of the external clitoris. In contrast, the possibility of achieving climax during penetration has been controversial. Six scientists with different experimental evidence debate the existence of the vaginally activated orgasm (VAO). To give reader of The Jour...

The anatomy and function of the G-spot remain highly controversial. Ultrasound studies of the clitoral complex during intercourse have been conducted to gain insight into the role of the clitoris and its relation to vagina and urethra during arousal and penetration. Our task was to visualize the anterior vaginal wall and its relationship to the cli...

No controversy can be more controversial than that regarding the existence of the G-spot, an anatomical and physiological entity for women and many scientists, yet a gynecological UFO for others. The pros and cons data have been carefully reviewed by six scientists with different opinions on the G-spot. This controversy roughly follows the Journal...

The existence of the G-spot remains controversial partly because no appropriate structure and innervation have been clearly demonstrated in this pleasurable vaginal area. Using sonography, we wanted to visualize the movements of the clitoris and its anatomical relationship with the anterior wall of the vagina during voluntary perineal contraction a...

The prevalence of invasive procedures in diagnosing female sexual dysfunctions and pathologies is high. There is a need for a less invasive evaluation tool and medical imaging of the clitoris may be a solution. The clitoris has already been studied with nuclear magnetic resonance but there are very few sonographic 2D and 3D studies despite the fact...

Ultrasonography is a good means for studying the clitoris and its relationship with the G spot. We used it to demonstrate that clitoral bodies have a descending movement and come close to the distal anterior vaginal wall during a voluntary or reflex contraction of levator ani muscles. This fact could explain the particular sensitivity of the G spot...

A case of osteogenesis imperfecta type II diagnosed in the first trimester of pregnancy. Lethal osteogenesis imperfecta is a disorder characterized by collagen abnormalities resulting in dwarfism, bone fragility and deformity leading to death in utero or in the perinatal period. Molecular and biochemical studies demonstrate that OI type II results...

Retrospective examination of ultrasound images obtained at 12 weeks of gestation in two fetuses with spina bifida demonstrated retraction of the frontal bones, resulting in an acorn-shaped head, the cerebral peduncles appearing parallel to each other. These craniocerebral signs may improve the accuracy of first-trimester diagnosis of spina bifida b...

Background The diagnosis of spina bifida before 14 weeks' remains difficult to achieve.We believe that the cephalic markers are accessible to an oriented sonogram at 12 weeks' if these signs are specially looked for. Improvements are necessary since prenatal diagnosis is moving towards the first trimester.Method Retrospective analysis of ultrasound...
