Male penis (penis) length

Male penis size - is a characteristic feature of the length and width of the male penis.

Measuring penis length - by measuring the width of the penis by placing a ruler on top of the penis when the person is standing and the member is in a fully erect position, and by measuring the width - by measuring the circumference of the penis in several places. removal. According to several studies, the average length of the penis is about 13-15 cm. While the question of what women prefer is controversial, special attention has been paid to the question of penis length in any period.

Measuring the length of the male penis

To accurately measure penis length, the penis must be in a fully erect position. It will be difficult to achieve this in a medical facility. A Brazilian doctor has resorted to injecting drugs into the penis to induce a full erection, and this has yielded more lasting results.

Some clinicians have measured the penis by stretching it as long as possible without moving it to measure it. Measurements obtained in independent measurements of male genitals are considered unreliable because they often tend to give exaggerated information about the length of the penis.

To accurately measure penis length, it is recommended to take several measurements on different days and at different times, in different erection situations. After that, the average value of the results is calculated. Such an approach also takes into account changes in penis length due to sexual arousal, time of day, room temperature, number of sexual intercourses, and errors during measurement.

The length of the penis should be measured when the person is standing, with the penis parallel to the floor. The penis is measured from the base of the penis to the point where it ends. The length of the penis is uncertain when measured along the lower surface or when the person is sitting or bent.

Circular size of the penis - is a measure of the circumference of the penis in the case of a complete erection. With differences, it is the average value of the three dimensions: the lower part of the penis head, the middle of the penis, and the base.

Results of a study of male penis size

Although the results obtained during the studies differ significantly, most U.S. experts point out that the average length of the penis in men is about 13-15 cm. In the 95% confidence interval, this ranges from 10,7 to 19,1 cm. In the case of a full erection, the normal circumference of the penis is about 12,3 cm. The average length of a male penis is slightly longer than its median size. The results below are mainly based on measurements conducted in the United States.

In infants, the average length of the penis is 4 cm, and in 90% of newborn boys, the length of the penis is between 2,4 and 5,5 cm. Slight growth of the penis is noted until the child is 5 years old. A very small increase is observed between the ages of 5 and puberty. At the beginning of puberty, the average length of the penis is 6 cm.

The penis grows to an average of 17-18 years, after which it thickens slightly and loses its length (about 4-5 mm).

The length of the penis in an erect position

Results obtained in independent measurements. Several scientific studies have studied the length of the penis in an erect state. According to online surveys and independent measurements of penis length, the average of the results obtained significantly larger than the average of the results obtained using medical and scientific methods.

Lengths measured by medical personnel. The following studies were conducted by state staff, but the experiment involved a different group of men (i.e., male volunteers of a younger age and race) and may therefore have been subjected to an unbiased selection.

According to a study published in the September 1996 issue of the Journal of Urology, the average length of the penis is 12,9 cm (measured by state staff). The aim of this study was to “provide an average measure of penis length and thickness to help provide medical advice to men who wish to enlarge their penis”.

A study published in December 2000 by the International Journal of the Study of Impotence showed that the average penis length in 50 European Jews was 13,6 cm (a measurement taken by state officials). The quote states: "The purpose of this study is to obtain the clinical dimensions of the penis at rest to predict what the size of the penis will be when an erection occurs." Erection was induced using pharmacological agents in all 50 men.

A study by LifeStyles Condomz found that the average length of the penis was 2,1 cm (measured by state staff) with a standard deviation of 14,9 cm. The purpose of this study was to make sure that condoms of the required size were available for sale.

Comparison with primates

Compared to other primates, including large representatives such as their gorillas, the human penis is larger in size, both absolute and relative to body length and thickness.

The length of the male penis and the reaction of the female genitals

According to a number of sexologists and other researchers, there are now some misconceptions about heterosexual sex. Thus, many men believe that deep vaginal penetration is important to stimulate a woman to orgasm. The most sensitive parts of the female genitals include the external genitalia, the clitoris, and the part of the vagina (about 10 cm) that is closest to the outside of the body. Studies have shown that part of the clitoris spreads to the external genitalia and vagina. Given that the average length of the male penis is more than this figure, most penises are long enough to satisfy their partners.

While most women find cervical stimulation unpleasant or painful, others see it as the basis of orgasm. The cervix is ​​sometimes understood to be a misinterpretation of the vagina domes, the deepest points of the vagina. The cervix and vaginal domes are located close to each other, between which direct and / or simultaneous stimulation is possible. It is known that the vagina can be an area that causes orgasm. Tests have shown that applying pressure to this area causes the vagina to get wet very quickly. The area of ​​sexual response in the anterior domes is called the epicenter, T point, or G point in women, the posterior dome is also called the epicenter, the rectum, and can be indirectly stimulated by pressure on the posterior joint.

When sexual desire is aroused, the vagina lengthens to an average length of 8.5 cm, but may continue to lengthen again in response to pressure. As the woman begins to have full sexual arousal, the vagina lengthens by 2/3 of its length and width, and the cervix is ​​pulled back. The walls of the vagina activate the soft elastic layers and they expand or contract according to the size of the penis using the pelvic muscles. This means that when there is the desired movement, the vagina lengthens and narrows to fit a penis of any size.

The effect of environment on penis length

It has been suggested that the reason for the difference in penis size between individuals may be not only heredity but also factors such as chemical pollution of the environment or exposure to chemicals, culture, nutrition. Endocrine disorders after exposure to chemicals (among many other problems) cause genital disorders in people of both sexes. Synthetic (e.g., pesticides, antibacterial triclosan, plasticizers for plastics) and natural chemicals (chemicals found in lavender and tea tree oils) are associated with varying degrees of endocrine disorders.

The plasticizer used to produce PVC, diethylhexiftalate, is the cause of penis enlargement. Diethylhexyphthalate metabolism products detected in the blood of pregnant women are the result of animal experiments in newborns, such as a decrease in the width of the penis, the shortness of the distance between the anus and the penis, the complete absence of testicles in boys. significantly related to events.

Maximum and minimum dimensions. Micropenis

The largest officially confirmed penis is 33.5 cm long and 15 cm in circumference, which was described by Dr. Robert L. Dickinson in the early twentieth century. The largest penis owner today is John Falcon of the United States, whose penis is 34,5 centimeters long.

In the case of a full erection, a genital organ that is otherwise considered normal but shorter than 7 cm in length is diagnosed as micropenis. The reasons for this may be a lack of growth hormones or gonadotropic hormones in the pituitary gland, impaired sensitivity to moderate androgens, various hereditary syndromes, and gene variations in certain hemoboxes. At a young age, this problem can be solved with hormones.
