[1] The motivation for investigating and collecting data on genital injuries has primarily been within the context of the legal system, such as proving or disproving sexual assault, rather than for medical purposes.
[1] Methods of studying and documenting genital injury has greatly improved through the use of tissue staining dyes and colposcopy.
These studies used several different methods to identify and document injuries, such as direct visualization, colposcopy, and/or tissue staining dyes.
These things include: first sexual experience, pregnancy, vigorous penetration, vaginal atrophy and spasm, previous operation or radiation therapy, disproportionate genitalia, penile ornamentation, and congenital anomalies.
[3] An inability to produce adequate vaginal lubrication and dilatation is thought to be an underlying cause of severe tears in the upper area of the vagina.
It is common for women to have a uterus that lies slightly to the right, this exposes the right fornix and makes it easier for some type of tearing or trauma to occur.
[2] Lacerations to the posterior peri-cervical vagina tend to occur in the missionary position, hips and legs hyperflexed.
[2] Diagnosing and treating vaginal trauma can often be difficult and delayed due to the sensitive and personal nature of these types of injuries; this also may be enhanced if the patient is young in age.
[3] The bleeding that results from extreme vaginal tears can be copious, leading to hemorrhagic shock, and the patient may need a blood transfusion.
[2] Vulvar trauma is more common in prepubertal children due to small labial fat pads and more physical activity.
Some of the reasons this may occur are self-mutilation with psychiatric disturbances, sexual need, accidents, iatrogenic injuries, or revenge and marriage breakdown.
This makes it easier for the testes to be struck, hit, kicked or crushed, which occurs most often during contact sports.
It can also turn in its space, causing a blockage of the vascular supply, this condition requires immediate medical attention (testicular torsion).
