PPSH usually consists of:

- a phallus midway in size between penis and clitoris,

- a chordee tethering it to the perineum,

- a urethral opening usually on the perineum (the hypospadias),

- and an incompletely closed urogenital opening, which resembles a small and shallow vagina.

Testes are often palpable in the scrotum or inguinal canals, and the karyotype is XY. In most cases there are no internal female structures such as a uterus or other Müllerian duct derivatives.

Pseudovaginal perineoscrotal hypospadias (PPSH) refers to a configuration of the external genitalia of an infant. In a sense, this configuration is roughly midway between normal male genitalia and normal female genitalia in structure and appearance. It is a relatively common form of genital ambiguity caused by undervirilization of genetic males due to several different intersex conditions.

A chordee may be caused by an underlying condition, such as a disorder of sex development or an intersex condition, or from a complication of circumcision, though some medical professionals do not consider it to be true chordee because the corporal bodies are normally formed. However, not all congenital chordee includes abnormal corpora, and case reports of damage to the corpus cavernosum from circumcision are noted in the literature; particularly as a complication of local anesthetic.

It is usually considered a congenital malformation of unknown cause. Since at an early stage of fetal development the penis is curved downward, it has been proposed that chordee results from an arrest of penile development at that stage.

The curvature of a chordee can involve

1. tethering of the skin with urethra and corpora of normal size;

2. curvature induced by fibrosis and contracture of the fascial tissue (Buck's fascia or dartos) surrounding the urethra;

3. disproportionately large corpora in relation to the urethral length without other demonstrable abnormality of either; or

4. a short, fibrotic urethra that tethers the penis downward (the least common type).

Severe degrees of chordee are usually associated with hypospadias, but mild degrees of curvature may occur in many otherwise normal males. When the curved penis is small and accompanied by hypospadias, deficiency of prenatal androgen effect can be inferred.

Hypospadias is usually diagnosed in the newborn nursery by the characteristic appearance of the penis. The urinary opening (“meatus”) is lower than normal, and most children have only partial development of the foreskin, lacking the normal covering for the glans on the underside. The abnormal “hooded” foreskin calls attention to the condition. However, not all newborns with partial foreskin development have hypospadias, as some have a normal urinary opening with a hooded foreskin, which is called “chordee without hypospadias”.

Megameatus with intact prepuce variant of hypospadias occurs when the foreskin is normal and the hypospadias is concealed. The condition is discovered during newborn circumcision or later in childhood when the foreskin begins to retract. A newborn with normal-appearing foreskin and a straight penis who is discovered to have hypospadias after a circumcision was started can have circumcision completed without worry for jeopardizing future hypospadias repair. Hypospadias is almost never discovered after a circumcision.

Hypospadias is a congenital disorder of the urethra where the urinary opening is not at the usual location on the head of the penis. It is the second-most common birth abnormality of the male reproductive system, affecting about one of every 250 males at birth. In roughly 90% of cases, the opening (meatus) is on or near the head of the penis (glans), referred to as distal hypospadias, while the remainder have proximal hypospadias with a meatus near or within the scrotum. Shiny tissue seen extending from the meatus to the tip of the glans, which would have made the urinary channel, is referred to as the urethral plate.

In most cases, the foreskin is also underdeveloped and does not wrap completely around the penis, leaving the underside of the glans penis uncovered. Also, a downward bending of the penis, commonly referred to as chordee, may occur. This is found in 10% of distal hypospadias and 50% of proximal hypospadias at the time of surgery. The scrotum may be higher than usual to either side of the penis, called penoscrotal transposition, adding to the abnormal overall appearance.

Hypospadias is thought to result from failure of the urinary channel to completely tubularize to the end of the penis; the cause is not known. Most often, it is the only abnormal finding, although in about 10% of cases, hypospadias may be part of a syndrome with multiple abnormalities.

The most common associated defect is an undescended testicle, which has been reported in around 3% of infants with distal hypospadias and 10% of those having proximal hypospadias. The combination of hypospadias and an undescended testicle sometimes indicates a disorder of sexual differentiation, and so additional testing may be recommended. Otherwise no blood tests or X-rays are routinely needed in newborns with hypospadias.

Hypospadias can be a symptom or indication of an intersex condition but the presence of hypospadias alone is not enough to classify as intersex. In most cases, hypospadias is not associated with any condition.

All forms of androgen insensitivity are associated with infertility, though exceptions have been reported for both the mild and partial forms.

PAIS is associated with a 50% risk of germ cell malignancy when the testes are undescended. If the testes are located intrascrotally, there may still be significant risk of germ cell malignancy; studies have not yet been published to assess this risk. Some men with PAIS may experience sexual dysfunction including impotence and anejaculation. A few AR mutations that cause PAIS are also associated with prostate and breast cancers.

Vaginal hypoplasia, a relatively frequent finding in CAIS and some forms of PAIS, is associated with sexual difficulties including vaginal penetration difficulties and dyspareunia.

At least one study indicates that individuals with an intersex condition may be more prone to psychological difficulties, due at least in part to parental attitudes and behaviors, and concludes that preventative long-term psychological counseling for parents as well as for affected individuals should be initiated at the time of diagnosis.

Lifespan is not thought to be affected by AIS.

A supplemental system of phenotypic grading that uses seven classes instead of the traditional three was proposed by pediatric endocrinologist Charmian A. Quigley et al. in 1995. The first six grades of the scale, grades 1 through 6, are differentiated by the degree of genital masculinization; grade 1 is indicated when the external genitalia is fully masculinized, grade 6 is indicated when the external genitalia is fully feminized, and grades 2 through 5 quantify four degrees of increasingly feminized genitalia that lie in the interim. Grade 7 is indistinguishable from grade 6 until puberty, and is thereafter differentiated by the presence of secondary terminal hair; grade 6 is indicated when secondary terminal hair is present, whereas grade 7 is indicated when it is absent. The Quigley scale can be used in conjunction with the traditional three classes of AIS to provide additional information regarding the degree of genital masculinization, and is particularly useful when the diagnosis is PAIS.

Partial androgen insensitivity syndrome is diagnosed when the degree of androgen insensitivity in an individual with a 46,XY karyotype is great enough to partially prevent the masculinization of the genitalia, but is not great enough to completely prevent genital masculinization. This includes any phenotype resulting from androgen insensitivity where the genitalia is partially, but not completely masculinized. Genital ambiguities are frequently detected during clinical examination at birth, and consequently, a PAIS diagnosis can be made during infancy as part of a differential diagnostic workup.

Pubertal undervirilization is common, including gynecomastia, decreased secondary terminal hair, and / or a high pitched voice. The phallic structure ranges from a penis with varying degrees of diminished size and hypospadias to a slightly enlarged clitoris. Wolffian structures (the epididymides, vasa deferentia, and seminal vesicles) are typically partially or fully developed. The prostate is typically small or impalpable. Müllerian remnants are rare, but have been reported.

The gonads in individuals with PAIS are testes, regardless of phenotype; during the embryonic stage of development, testes form in an androgen-independent process that occurs due to the influence of the SRY gene on the Y chromosome. Cryptorchidism is common, and carries with it a 50% risk of germ cell malignancy. If the testes are located intrascrotally, there may still be significant risk of germ cell malignancy; studies have not yet been published to assess this risk.

Predominantly male phenotypes vary in the degree of genital undermasculinization to include micropenis, chordee, scrotum, and / or pseudovaginal perineoscrotal hypospadias. Impotence may be fairly common, depending on phenotypic features; in one study of 15 males with PAIS, 80% of those interviewed indicated that they had some degree of impotence. Anejaculation appears to occur somewhat independently of impotence; some men are still able to ejaculate despite impotence, and others without erectile difficulties cannot. Predominantly female phenotypes include a variable degree of labial fusion and clitoromegaly. Ambiguous phenotypic states include a phallic structure that is intermediate between a clitoris and a penis, and a single perineal orifice that connects to both the urethra and the vagina (i.e. urogenital sinus). At birth, it may not be possible to immediately differentiate the external genitalia of individuals with PAIS as being either male or female, although the majority of individuals with PAIS are raised male.

Given the wide diversity of phenotypes associated with PAIS, the diagnosis is often further specified by assessing genital masculinization. Grades 2 through 5 of the Quigley scale quantify four degrees of increasingly feminized genitalia that correspond to PAIS.

Grade 2, the mildest form of PAIS, presents with a predominantly male phenotype that presents with minor signs of undermasculinized genitalia, such as isolated hypospadias, which can be severe. Hypospadias may manifest with a partially formed channel from the urethral opening to the glans. Until recently, it was thought that isolated micropenis was not a manifestation of PAIS. However, in 2010, two cases of PAIS manifesting with isolated micropenis were documented.

Grade 3, the most common phenotypic form of PAIS, features a predominantly male phenotype that is more severely undermasculinized, and typically presents with micropenis and pseudovaginal perineoscrotal hypospadias with scrotum.

Grade 4 presents with a gender ambiguous phenotype, including a phallic structure that is intermediate between a clitoris and a penis. The urethra typically opens into a common channel with the vagina (i.e. urogenital sinus).

Grade 5, the form of PAIS with the greatest degree of androgen insensitivity, presents with a mostly female phenotype, including separate urethral and vaginal orifices, but also shows signs of slight masculinization including mild clitoromegaly and / or partial labial fusion.

Previously, it was erroneously thought that individuals with PAIS were always infertile; at least one case report has been published that describes fertile men that fit the criteria for grade 2 PAIS (micropenis, penile hypospadias, and gynecomastia).

Additional findings that may be present in HFGS according to the latest research are:

- Limited metacarpophalangeal flexion of the thumb or limited ability to oppose the thumb and fifth finger

- Hypoplastic thenar eminences

- Medial deviation of the great toe (hallux varus), a useful diagnostic sign when present

- Small great toenail

- Fifth-finger clinodactyly, secondary to a shortened middle phalanx

- Short feet

- Altered dermatoglyphics of the hands; when present, primarily involving distal placement of the axial triradius, lack of thenar or hypothenar patterning, low arches on the thumbs, thin ulnar loops (deficiency of radial loops and whorls), and a greatly reduced ridge count on the fingers

Radiographic findings

- Hypoplasia of the distal phalanx and first metacarpal of the thumbs and great toes

- Pointed distal phalanges of the thumb

- Lack of normal tufting of the distal phalanges of the great toes

- Fusions of the cuneiform to other tarsal bones or trapezium-scaphoid fusion of the carpals

- Short calcaneus

- Occasional bony fusions of the middle and distal phalanges of the second, third, fourth, or fifth toes

- Delayed carpal or tarsal maturation

- Metacarpophalangeal profile reflecting shortening of the first metacarpal, the first and second phalanges, and the second phalanx of the second and fifth digits

Urogenital Defects

Females may have the following:

- Vesicoureteral reflux secondary to ureteric incompetence

- Ectopic ureteral orifices

- Trigonal hypoplasia

- Hypospadiac urethra

- Subsymphyseal epispadias

- Patulous urethra

- Urinary incontinence (related to structural anomalies and weakness of the bladder sphincter muscle)

- Small hymenal opening

- Various degrees of incomplete Müllerian fusion with or without two cervices or a longitudinal vaginal septum

Males may have the following:

- Retrograde ejaculation (related to structural anomalies and weakness of the bladder sphincter muscle)

Hand-foot-genital syndrome (HFGS) is characterized by limb malformations and urogenital defects. Mild bilateral shortening of the thumbs and great toes, caused primarily by shortening of the distal phalanx and/or the first metacarpal or metatarsal, is the most common limb malformation and results in impaired dexterity or apposition of the thumbs. Urogenital abnormalities include abnormalities of the ureters and urethra and various degrees of incomplete Müllerian fusion in females and hypospadias of variable severity with or without chordee in males. Vesicoureteral reflux, recurrent urinary tract infections, and chronic pyelonephritis are common; fertility is normal.

Heart abnormalities are present in 25–35% of people with distal 18q-. The majority of these defects are septal. Congenital orthopedic anomalies are also relatively common, particularly rocker-bottom feet or clubfoot. Cleft lip and palate are relatively common in people with distal 18q-. Kidney abnormalities have also been reported and include horseshoe kidney, hydronephrosis, polycystic kidney, and absent kidney. Boys with distal 18q- may have genital anomalies, the most frequent being cryptorchidism and hypospadias.

Dysmyelination is a common finding in people with distal 18q-, present in about 95%. Hypoplasia of the corpus callosum is also a common finding.

Mutations that result in some residual 21-hydroxylase activity cause milder disease, traditionally termed simple virilizing CAH (SVCAH). In these children the mineralocorticoid deficiency is less significant and salt-wasting does not occur. However, genital ambiguities are possible.

Virilization of genetically female (XX) infants usually produces obvious genital ambiguity. Inside the pelvis, the ovaries are normal and since they have not been exposed to testicular antimullerian hormone (MIF), the uterus, fallopian tubes, upper vagina, and other mullerian structures are normally formed as well. However, the high levels of testosterone in the blood can enlarge the phallus, partially or completely close the vaginal opening, enclose the urethral groove so that it opens at the base of the phallus, on the shaft or even at the tip like a boy. Testosterone can cause the labial skin to become as thin and rugated as a scrotum, but cannot produce palpable gonads (i.e., testes) in the folds.

Thus, depending on the severity of hyperandrogenism, a female infant can be mildly affected, obviously ambiguous, or so severely virilized as to appear to be a male. Andrea Prader devised the following Prader scale as a way of describing the degree of virilization.

- An infant at stage 1 has a mildly large clitoris and slightly reduced vaginal opening size. This degree may go unnoticed or may be simply assumed to be within normal variation.

- Stages 2 and 3 represent progressively more severe degrees of virilization. The genitalia are obviously abnormal to the eye, with a phallus intermediate in size and a small vaginal opening.

- Stage 4 looks more male than female, with an empty scrotum and a phallus the size of a normal penis, but not quite free enough of the perineum to be pulled onto the abdomen toward the umbilicus (i.e., what is termed a chordee in a male). The single small urethral/vaginal opening at the base or on the shaft of the phallus would be considered a hypospadias in a male. X-rays taken after dye injection into this opening reveal the internal connection with the upper vagina and uterus. This common opening can predispose to urinary obstruction and infection.

- Stage 5 denotes complete male virilization, with a normally formed penis with the urethral opening at or near the tip. The scrotum is normally formed but empty. The internal pelvic organs include normal ovaries and uterus, and the vagina connects internally with the urethra as in Stage 4. These infants are not visibly ambiguous, and are usually assumed to be ordinary boys with undescended testes. In most cases, the diagnosis of CAH is not suspected until signs of salt-wasting develop a week later.

When the genitalia are determined to be ambiguous at birth, CAH is one of the leading diagnostic possibilities. Evaluation reveals the presence of a uterus, extreme elevation of 17OHP, levels of testosterone approaching or exceeding the male range but low AMH levels. The karyotype is that of an ordinary female: 46,XX. With this information, the diagnosis of CAH is readily made and female sex confirmed.

Evaluation of ambiguous genitalia is described in detail elsewhere. In most cases it is possible to confirm and assign female sex within 12–36 hours of birth. The exception are the rare, completely virilized genetic females (Prader stage 5), who present the most challenging assignment and surgery dilemmas, discussed below.

When the degree of ambiguity is obvious, corrective surgery is usually offered and performed. As reconstructive surgery on infant genitalia has become a focus of controversy, the issues are described in more detail below.

The hallmark sign of urethral stricture is a weak urinary stream. Other symptoms include:

- Splaying of the urinary stream

- Urinary frequency

- Urinary urgency

- Straining to urinate

- Pain during urination

- Urinary tract infection

- Prostatitis

- Inability to completely empty the bladder.

Some patients with severe urethral strictures are completely unable to urinate. This is referred to as acute urinary retention, and is a medical emergency. Hydronephrosis and renal failure may also occur.

Urethral strictures most commonly result from injury, urethral instrumentation, infection, non-infectious inflammatory conditions of the urethra, and after prior hypospadias surgery. Less common causes include congenital urethral strictures and those resulting from malignancy.

Urethral strictures after blunt trauma can generally be divided into two sub-types;

- Pelvic fracture-associated urethral disruption occurs in as many as 15% of severe pelvic fractures. These injuries are typically managed with suprapubic tube placement and delayed urethroplasty 3 months later. Early endoscopic realignment may be used in select cases instead of a suprapubic tube, but these patients should be monitored closely as vast majority of them will require urethroplasty.

- Blunt trauma to the perineum compresses the bulbar urethra against the pubic symphysis, causing a "crush" injury. These patients are typically treated with suprapubic tube and delayed urethroplasty.

Other specific causes of urethral stricture include:

- Instrumentation (e.g., after transurethral resection of prostate, transurethral resection of bladder tumor, or endoscopic kidney surgery)

- Infection (typically with Gonorrhea)

- Lichen sclerosus

- Surgery to address hypospadias can result in a delayed urethral stricture, even decades after the original surgery.

Clinically, McKusick–Kaufman syndrome is characterized by a combination of three features: postaxial polydactyly, heart defects, and genital abnormalities:

- Vaginal atresia with hydrometrocolpos

- Double vagina and/or uterus.

- Hypospadias, chordee (a downward-curving penis), and undescended testes (cryptorchidism).

- ureter stenosis or ureteric atresia

McKusick–Kaufman syndrome is a genetic condition associated with MKKS.

The condition is named for Dr. Robert L. Kaufman and Victor McKusick. It is sometimes known by the abbreviation MKS. In infancy it can be difficult to distinguish between MKS and the related Bardet–Biedl syndrome, as the more severe symptoms of the latter condition rarely materialise before adulthood.
