From this, it can be concluded that penile growth is typically complete not later than age 17, and possibly earlier.

This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
The external genitalia of both males and females have similar origins. They arise from the genital tubercle that forms anterior to the cloacal folds proliferating mesenchymal cells around the cloacal membrane. The caudal aspect of the cloacal folds further subdivides into the posterior anal folds and the anterior urethral folds.
Bilateral to the urethral fold, genital swellings tubercles become prominent. These structures are the future scrotal swellings and labia majora in males and females, respectively. The genital tubercles of an eight week old embryo of either sex are identical. They both have a glans area, which will go on to form the glans clitoridis females or glans penis males , a urogenital fold and groove, and an anal tubercle.
At around ten weeks, the external genitalia are still similar. At the base of the glans, there is a groove known as the coronal sulcus or corona glandis. It is the site of attachment of the future prepuce.
Just anterior to the anal tubercle, the caudal end of the left and right urethral folds fuse to form the urethral raphe. The lateral part of the genital tubercle called the lateral tubercle grows longitudinally and is about the same length in either sex. The male external genitalia include the penis , the male urethra , and the scrotum. The female external genitalia include the clitoris , the labia majora , and the labia minora , which are collectively called the vulva.
External genitalia vary widely in external appearance among different people. The difference is that the glans clitoridis packs them into a volume only about one-tenth the size of the glans penis.

Metrics details. Does the size of the male penis, in terms of length or width, make a difference in female sexual satisfaction? To study the effect of penis width vs. None reported they did not know, or that width and length were equally satisfying. Implications are discussed, including the fact that the data seem to contradict Masters and Johnson about penis size having no physiological effect on female sexual satisfaction. When people speak of penis size, they typically refer to length. Thus, a man with a short but wide penis would probably think of himself as having a small penis, and would be so thought of by others, too.
However, width is part of size, although usually not acknowledged. Does width contribute to female sexual satisfaction?
Or, perhaps size is unrelated to female sexual enjoyment. The famous sex researchers Masters and Johnson [ 1 , 2 ] have concluded that size of the male penis can have no true physiological effect on female sexual satisfaction. They base this conclusion on their physiological studies that show that the vagina adapts to fit the size of the penis. Because of this vaginal adaptation, they refer to the vagina as a potential space rather than an actual space.
Thus, despite the worries of many males about the size of their penis, Masters and Johnson concluded that any size penis will fit and provide adequate sexual stimulation to the female. The present study was conducted to see if female college students would report their sexual satisfaction related to penis length, width, or neither.
To test the notion of the possible importance of length vs. The female students ranged in age from 18 to 25 years old. In person or via telephone, the females were asked "In having sex, which feels better, length of penis or width of penis?
There were also no effects for telephone vs. All female participants answered the question, perhaps because they knew the student asking the question. No females reported that they could not tell any difference. Some did report that sex in a relationship was better than sex without commitment.
Masters and Johnson [ 1 , 2 ] have said that penis size should have no physiological effect on female sexual enjoyment, since the vagina adapts to fit the size of the penis. However, Masters and Johnson could be correct if the present subjects are only reporting their psychological preference, and not showing a true physiological preference. In other words, the present study solely assessed females' perceived level of sexual satisfaction, which might differ from actual physiological arousal and satisfaction.
It is not obvious why a wide penis would be preferred to a long penis, but speculation would suggest the following. Penis width may be important due to a penis thick at the base providing greater clitoral stimulation as the male thrusts into the female during sexual intercourse. If this is correct, then Masters and Johnson are wrong about penis size being unrelated, physiologically, to female sexual satisfaction. Masters, Johnson, and Kolodny [ 3 ] do not totally rule out penis size being relevant, but they suggest that it is likely of minor importance for female sexual satisfaction see especially pages in Masters, Johnson, and Kolodny [ 3 ].
Another possibility is that a wider penis provides the woman with a greater feeling of fullness, which is psychologically, and perhaps physiologically, satisfying. Further research on sex is necessary to understand the various influences on sexual attitudes and behavior, including how attitudes influence behavior, if, in fact, they do [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. Different samples could be studied, as well as using different methods of investigation. One might have women rank order different aspects of sexual satisfaction, including such things as physical attractiveness of the partner, romantic feelings, love, and other things, as well as penis size.
This would give an understanding of where the different attributes rank in women's stated preferences. But, width vs. Also, it may be that Masters and Johnson [ 1 , 2 , 3 ] were wrong about penis size having little or no physiological effect on women's sexual satisfaction. However, the current data cannot provide a final answer, since they are based on self reports of women surveyed about penis length vs. Boston, Little, Brown. New York, Harper Collins.
