|Erect penis: LENGTH 4.23 inches GIRTH 4.85 inches|
A study conducted by LifeStyles Condoms during 2001 Spring Break in Cancún found an average of
The majority of penises are of sufficient length to satisfy their partners.While results vary across studies, the consensus is that the average human penis is approximately 12.7 - 15 cm (5 - 5.9 in) in length with a 95% confidence interval of (10.7 cm, 19.1 cm) (or, equivalently,(4.23 in, 7.53 in)). The typical girth or circumference is approximately 12.3 cm (4.85 in) when fully erect. The average penis size is slightly larger than the median size (or, put another way, most penises are below average in size).
PENIS SIZE and VAGINA SIZEDuring arousal, the vagina lengthens rapidly to an average of about 4 in.(8.5 cm). As the woman becomes fully aroused, the vagina tents (last ²⁄₃ expands in length and width) while the cervix retracts. The walls of the vagina are composed of soft elastic folds of mucous membrane skin which stretch or contract (with support from pelvic muscles) to the size of the penis. Thus vagina is able to contract and grip over the penis, whether it be smaller or bigger in size.
|This means (with proper arousal) the vagina stretches/contracts to accommodate virtually any size penis, from small to large.|
The most sensitive area of the female genitals includes the vulva, clitoris, and the section of vagina closest to the outside of a woman's body, which is roughly 10 centimeters (4 in) in length. Research has found that portions of the clitoris extend into the vulva and vagina . Given that the average penis size is above this length, the majority of penises are of sufficient length to satisfy their partners.
A study published in the September 1996 Journal of Urology
concluded that average erect length was 12.9 cm (5.08 in).
It was concluded: “Neither patient age nor size of the flaccid penis accurately predicted erectile length.”
Erection was pharmacologically induced (not natural, but medicine induced erect size was measured)in 80 physically normal American men in the above study.
A study published in the December 2000 International Journal of Impotence Research found that average erect penis length was 13.6 cm (5.35 in)
A study conducted by LifeStyles Condoms found an average of 14.9 cm (5.9 in) with a standard deviation of 2.1 cm (0.8 in). 401 college students volunteered to be measured during 2001 Spring Break in Cancún, Mexico, of which 300 gained an erection to be clinically measured (without pharmacological aid). The 300 effective measurements makes this study double the size of any prior study that uses medical staff to measure penis size.
Length of the flaccid penis does not necessarily correspond to length of the erect penis; some smaller flaccid penises can grow much larger, and some larger flaccid penises cannot grow much larger.
The penis and scrotum can contract involuntarily in reaction to cold temperatures or nervousness, referred to by the slang term "shrinkage", due to action by the cremaster muscle.
To get the most accurate measurements for an individual's penis size, it has been recommended that several measurements be taken at different times, preferably with different erections on different days. Then average these figures together. This is to account for what may be natural variability in size due to factors such as arousal level, time of day, room temperature, frequency of sexual activity, and unreliability of the measurement methods.
When to measure the penis
How to measure the
The length can be measured with the subject standing and the penis held parallel to the floor. The penis is measured along the top, from the base to the tip. Results are inaccurate if the measurement is taken along the underside of the penis, or if the subject is seated or prone.
length of penis
How to measure the
Penis circumference or girth is measured by using a tape measure or a piece of string and a ruler while the penis is completely erect. It is variously quoted as an average of three measurements: just below the glans penis, in the middle of the shaft, and at the base.

Why people don't get correct measurement?
What are the
A penis must be completely erect in order to obtain an accurate measurement. This may be difficult to achieve in a clinical setting.
At least one Brazilian doctor resorted to injecting penises with drugs to induce erection, which gave more consistent results. Some clinicians measure the penis by stretching the flaccid penis as far as comfortably possible. Self-reported measurements tend to be unreliable because men often want to report a larger penis size.
