Virilization capacity can be assessed by measuring the response to a trial of exogenous androgens; some studies have measured the growth of the phallus in response to exogenous testosterone or dihydrotestosterone, while others have measured the change in sex hormone binding globulin (SHBG) in response to the artificial androgen stanozolol to assess androgen sensitivity. Some experts have cautioned that it remains to be proved that a good response to exogenous androgens in neonates is a good predictor of androgen response at puberty. If a mutation in the AR gene is found, it is important to determine whether the mutation is inherited or de novo (i.e. a somatic mutation); a certain amount of the wild-type androgen receptor will be present in cases of somatic mutation, which can induce virilization at puberty. A genital skin fibroblast study  and a human chorionic gonadotropin (hCG) stimulation test  may also provide information helpful in the assessment of virilization capacity. Psychosexual development is influenced by many factors, including the timing, amount, and type of androgen exposure, receptor functionality, and environment, and is thus difficult to predict. Gender identity begins to develop before 3 years of age, although the earliest age at which it can be reliably assessed has yet to be determined. Approximately 25% of individuals with PAIS are dissatisfied with their assigned gender, regardless of being raised as male or female. One study reports that 46,XY individuals born with micropenis and no hypospadias are better off being raised male, despite the success of some being raised female.
He wrote that they usually were the subject of desire when a weak person "makes use of such substitutes" or when an uncontrollable instinct which will not allow delay seeks immediate gratification and cannot find a more appropriate object.In 1908, Swiss neuroanatomist and psychiatrist Auguste Forel wrote of the phenomenon, proposing that it be referred to it as "Pederosis", the "Sexual Appetite for Children". Similar to Krafft-Ebings work, Forel made the distinction between incidental sexual abuse by persons with dementia and other organic brain conditions, and the truly preferential and sometimes exclusive sexual desire for children. However, he disagreed with Krafft-Ebing in that he felt the condition of the latter was largely ingrained and unchangeable.The term pedophilia became the generally accepted term for the condition and saw widespread adoption in the early 20th century, appearing in many popular medical dictionaries such as the 5th Edition of Stedmans in 1918. In 1952, it was included in the first edition of the Diagnostic and Statistical Manual of Mental Disorders. This edition and the subsequent DSM-II listed the disorder as one subtype of the classification "Sexual Deviation", but no diagnostic criteria were provided. The DSM-III, published in 1980, contained a full description of the disorder and provided a set of guidelines for diagnosis. The revision in 1987, the DSM-III-R, kept the description largely the same, but updated and expanded the diagnostic criteria. Law and forensic psychology

Pedophilia is not a legal term, and having a sexual attraction to children is not illegal.
