Micropenis can have a variety of causes. Since it is defined statistically, a large proportion of males with micropenis are simply normal but in the lowest percentile of normal size. As for many other conditions, the term "idiopathic" is often used when a cause cannot be determined. Of the abnormal conditions associated with micropenis, most are conditions of reduced prenatal androgen production or effect. Examples include abnormal testicular development (testicular dysgenesis, Klinefelter syndrome, Leydig cell hypoplasia), specific d ...

Main article: Micropenis A penis whose stretched flaccid length is more than approximately 2.5 standard deviations below average size for the age group but otherwise formed normally is referred to in a medical context as a micropenis. Some of the identifiable causes are deficiency of pituitary growth hormone and/or gonadotropins, mild degrees of androgen insensitivity, a variety of genetic syndromes, and HOX9 gene variations. Some types of micropenis can be improved with growth hormone or testosterone treatment in early childhood. Penis-enlargement self-t ...

Andrology (from the Greek andros, man) is the medical specialty that deals with male health, particularly relating to the problems of the male reproductive system and urological problems that are unique to men. Gynaecology deals with medical issues which are specific to women. Men are more susceptible to heart disease than women, and tend to have a slightly shorter natural average life span. However, men are more resistant to many conditions th ...

Cryptorchidism is a medical term referring to absence from the scrotum of one or both testes. This usually represents failure of the testis to move, to "descend," during fetal development from an abdominal position, through the inguinal canal, into the ipsilateral scrotum. About 3% of full-term infant boys are born with at least one undescended testis, making cryptorchidism the most common birth defect of male genitalia. A testis absent from the normal scrotal position can be: found anywhere along the "path ...

In a 2005 study by the University of California Los Angeles, 45% of men responded they would prefer their penis size increased.[1] 84% of respondents rated their penis size as average to above average. There is a similar perception gap in women's perceptions of their breasts. (See: Human Breast Size) 70% desired more ample or rounder breasts. Men may tend to misjudge the size of their penis relative to that of other men they have seen naked, simply because of the foreshortening effect obtained from always looking down at the penis fro ...

There are a variety of different ways to measure a penis; and there are a number of difficulties in doing so. First of all, a penis must be maximally erect to do so, and in a clinical setting this is difficult to achieve. At least one Brazilian doctor resorted to injecting penises, giving much more consistent results. Relying on self-reporting of penis size is problematic, since some patients exaggerate or a ...

One source of continued debate is the extent to which women actually prefer certain penis sizes. In the 2005 UCLA study, 85% of women said they were "very satisfied" with their partner's size.[2] [3] Recently, there has been greater media attention to the issue of penis size and women being more vocal about their preferences. Television shows such as Sex and the City and Ally McBeal popularized the penis size issue when characters in these TV shows stated their preference for well-endowed men and rejected men who had onl ...

While it is commonly accepted that physical differences between races do exist (such as eye color, hair texture, noses, height, and hip width), the subject of penis size variation between different races has been a taboo since it could imply one race is "superior" or "inferior" to another. The question of race and penis size is therefore very controversial, and has not been definitively established. Although the common perception is that Africans are larger on average compared to Caucasians, and East Asians are smaller—however whether or n ...

Regarding the length of the adult fully erect penis (measured along the top of the penis from the groin to the tip), several studies have been performed. Those studies that relied on self-measurement consistently reported a higher average than those that had staff take the measurements. An UCSF study by Wessells et.al. published in 1996 found an average of 5.1 inches (13.0 cm). (Measured by staff) A study by a Brazilian urologist found an average of 5.7 inches (14.5 cm).

In some cultures, mass hysteria involving the believed removal or shrinking of the penis has been observed. See penis panic for a detailed discussion. Many theories are held in popular culture, that it is possible to predict the size of someone's penis by observing other features. The features usually selected are Size of hands Size of feet, or shoe size Size of nose Many place great stock in these theories; however, no actual statistical evidence correlating penis size to any other part of the body exists. The shoe size theory does not hold up under statis ...

Kallmann syndrome is characterized by: Hypogonadotropic hypogonadism (a lack of the pituitary hormones LH and FSH) Congenital (present from birth) anosmia (complete inability to smell) or hyposmia (decreased ability to smell). It can also be associated with optic problems, such as color blindness or optic atrophy, nerve deafness, cleft palate, cryptorchidism, renal agenesis, and mirror movement disorder. However, it is not clear at this time how or if these other problems have the same cause as the hypogonadism and anosmia and these other problems are more oft ...

The report and subsequent book about Reimer influenced several medical practices and reputations, and even current understanding of the determinants of gender identity. The case accelerated the decline of sex reassignment and surgery for unambiguous XY male infants with micropenis, various other rare congenital malformations, and penile loss in infancy (described in more detail in intersex.) It supported the arguments of those who feel that prenatal and early-infantile hormones have a strong influence on brain differentiation, gender ...
