Anogenital distance (AGD) is the distance from the midpoint of the anus to the genitalia, the underside of the vagina, the clitoris or the scrotum. It is considered medically significant for a number of reasons, in both humans and other animals, including sex determination and as a marker of endocrine disruptor exposure. [1]
In males, it is found between the bulb of the penis and the anus; in females, it is found between the vagina and anus, and about 1.25 cm (0.49 in) in front of the latter. The perineal body is essential for the integrity of the pelvic floor, particularly in females.
The perineal raphe is a visible line or ridge of tissue on the body that extends from the anus through the perineum to the scrotum (male) or the vulva (female). It is found in both males and females, arises from the fusion of the urogenital folds, and is visible running medial through anteroposterior, to the anus where it resolves in a small knot of skin of varying size.
The labia minora is skin folds that surround your urethra and vagina. If you have excess skin, ... Perineoplasty to strengthen the perineum, the area between the vagina and anus.
The perineum attaches across the gap between the inferior pubic rami bilaterally and the perineal body. This grouping of muscles constricts to close the urogenital openings. The perineum supports and functions as a sphincter at the opening of the vagina. Other structures exist below the perineum that support the anus. [3] [6]
In addition to nerve endings, pleasure from anal intercourse may be aided by the close proximity between the anus and the prostate for males, and vagina, clitoral legs and anal area for females. This is because of indirect stimulation of the prostate and vagina or clitoral legs.
In women, an anatomical area known as the perineum separates the opening of the vagina from that of the anus. Each opening is surrounded by a wall, and the anal wall is separated from the vaginal wall by a mass of soft tissue including: The muscles of the anus (corrugator cutis ani, the internal anal sphincter and the external anal sphincter)
The two types of episiotomies performed are the medial incision and the medio-lateral incision. The median incision is a perpendicular cut between the vagina and the anus and is the most common. [44] [175] The medio-lateral incision is made between the vagina at an angle and is not as likely to tear through to the anus. The medio-lateral cut ...
