According to Wardell B. Pomeroy, in his careful and detailed survey, published in 1970, the largest penis was found to be 9½ inch (24,1 cm) in erection.

In an earlier inter-racial survey, Dr. Jacobus’s 1935 publication – “L’Ethnologie du Sens Genitale”, larger dimensions were recorded. In this survey, organs nearly 12 inch (30,5 cm) in length are reported.
Of all penis sizes quoted in the literature the largest is unquestionably the 14 inch (35,6 cm) erect organ mentioned by Dr. David Reuben in “Everything You Always Wanted to Know About Sex”. But as no source is quoted.

About penis

The penis is an external sexual organ of certain biologically male organisms, in both vertebrates and invertebrates. The penis is a reproductive organ and for placental mammals, additionally serves as the external organ of urination. The penis is generally found on mammals and reptiles.

Structure

The human penis is made up of three columns of tissue: two corpora cavernous lie next to each other on the dorsal side and one corpus spongiosum lies between them on the ventral side. The enlarged and bulbous-shaped end of the corpus spongiosum forms the glans penis, which supports the foreskin or prepuce, a loose fold of skin that in adults can retract to expose the glans. The area on the underside of the penis, where the foreskin is attached, is called the frenum.

Ejaculation

Ejaculation is the ejecting of semen from the penis, and is usually accompanied by orgasm. A series of muscular contractions delivers semen, containing male gametes known as sperm cells or spermatozoa, from the penis (and into the vagina, if for reproductive intention via sexual intercourse). It is usually the result of sexual stimulation, which may include prostate stimulation. Rarely, it is due to prostatic disease. Ejaculation may occur spontaneously during sleep (a nocturnal emission or wet dream). Anejaculation is the condition of being unable to ejaculate. Ejaculation has two phases: emission and ejaculation proper. The emission phase of the ejaculatory reflex is under control of the sympathetic nervous system, while the ejaculatory phase is under control of a spinal reflex at the level of the spinal nerves via the pudendal nerve. A refractory period succeeds the ejaculation, and sexual stimulation precedes it.

Erection angle

Although many erect penises point upwards (see illustration), it is common and normal for the erect penis to point nearly vertically upwards or nearly vertically downwards or even horizontally straight forward, all depending on the tension of the suspensory ligament that holds it in position. The following table shows how common various erection angles are for a standing male. In the table, zero degrees is pointing straight up against the abdomen, 90 degrees is horizontal and pointing straight forward, while 180 degrees would be pointing straight down to the feet. An upward pointing angle is most common.[5] Occurrence of Erection AnglesAngle (degrees)    Percent
