[20] [31] [43] When phimosis is simply equated with nonretractility of the foreskin after age 3 years, considerably higher incidence rates have been reported. [27] [44] Others have described incidences in adolescents and adults as high as 50%, though it is likely that many cases of physiological phimosis or partial nonretractility were included ...
In male human anatomy, the glans penis or penile glans, [1] commonly referred to as the glans, (/ ɡ l æ n z /; from Latin glans meaning "acorn") [2] is the bulbous structure at the distal end of the human penis that is the human male's most sensitive erogenous zone and primary anatomical source of sexual pleasure.
For example, a study shows that undescended testicles affects approximately 4.8 percent of all Malaysian male newborns. [28] During normal development, testes form in the retroperitoneum, the back part of the abdomen, and subsequently descend through the inguinal canal into the scrotum. Diagnosing undescended testicles involves a physical ...
Penile plethysmography (PPG) or phallometry is a measurement of blood flow to the penis, typically used as a proxy for measurement of sexual arousal.The most commonly reported methods of conducting penile plethysmography involves the measurement of the circumference of the penis with a mercury-in-rubber or electromechanical strain gauge, or the volume of the penis with an airtight cylinder and ...
Balanitis "is a common condition affecting 11% of adult men seen in urology clinics and 3% of children" in the United States; globally, balanitis "may occur in up to 3% of uncircumcised males". [ 14 ]
The diagnosis of severe frenulum breve is almost always confused with that of phimosis and a generally tight foreskin, since the symptom is difficulty retracting the foreskin. Most men with phimosis also have frenulum breve to a certain extent. [5] A milder frenulum breve may go unrecognized, since foreskin may retract over the glans variably.
Cryptorchidism occurs at a much higher rate in a large number of congenital malformation syndromes. Among the more common are Down syndrome , [ 8 ] Prader–Willi syndrome , and Noonan syndrome . In vitro fertilization, use of cosmetics by the mother, and pre-eclampsia have also been recognized as risk factors for development of cryptorchidism.
Paraphimosis is usually caused by medical professionals or parents who handle the foreskin improperly.[4] [6] The foreskin may be retracted during penile examination, penile cleaning, urethral catheterization, or cystoscopy; if the foreskin is left retracted for a long period, some of the foreskin tissue may become oedematous (swollen with fluid), which makes subsequent reduction of the ...
