A review published in 2007 issue of BJU International, have shown that average erect penis length is 14–16 cm (5.5-6.3 in) and its
girth is 12–13 cm (4.7-5.1 in).

This paper compares results of twelve studies conducted on different populations in several countries.

Flaccid length

One study found the mean flaccid penis length to be 3.5 inches (8.9 cm) (measured by staff). A review of several studies have shown average flaccid length to be 9–10 cm. 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.

Stretched length

Flaccid penis length is a poor estimate of erect length, a better estimate is stretched length, that is 12–13 cm, as shown in review by Wylie and Erdley.

    Hi doctor,

    I am Amar here, a 20 year old college going guy, having a normal and fine life. For additional info, I never exprienced SEX before in my life span. Now coming to my problem, from about 2-3 months I have expriences less erection and potential in my penis and according to me (as i thought or feared of) is due to vigourous masturbation that I done in my past 4-5 years. In the beginning I exprienced my penis as really hard and fully potential and erection time and ejectio eime are too good and it continues for all those years. But from last 2-3 months, I am expriencing a very short ejection time(around 1.5-2 minutes) and also I am feeling less erection and also for this erection, erection time is less. Now I am afraid that if I really vanished my sexual life or it is any natural phenomenon that can be faced by everyone in his life. I stop(or we can say reduce) my masturbation as I am feeling it is the only cause of my ill sexual health.
    I also wanna added that in my past masturbation exprience…on an average I masturbate 20 -22 day /month and in which some days are of 2-3 times of masturbation.
    Also you are the first doc that I am sharing my problem. Please guide me that what are the absolute reason for this problem and what steps I took forward to help me out of this situaion or I should start any medical treatment to took over the situation.
    Hope to hear from you soon. I shall be highly obiliged to you.
    Thanking you.
