A disorder of sexual development transmitted as an X-linked recessive trait. These patients have a karyotype of 46,XY with end-organ resistance to androgen due to mutations in the androgen receptor (RECEPTORS, ANDROGEN) gene. Severity of the defect in receptor quantity or quality correlates with their phenotypes. In these genetic males, the phenotypic spectrum ranges from those with normal female external genitalia, through those with genital ambiguity as in Reifenstein Syndrome, to that of a normal male with INFERTILITY.
Proteins, generally found in the CYTOPLASM, that specifically bind ANDROGENS and mediate their cellular actions. The complex of the androgen and receptor migrates to the CELL NUCLEUS where it induces transcription of specific segments of DNA.
A number of syndromes with defective gonadal developments such as streak GONADS and dysgenetic testes or ovaries. The spectrum of gonadal and sexual abnormalities is reflected in their varied sex chromosome (SEX CHROMOSOMES) constitution as shown by the karyotypes of 45,X monosomy (TURNER SYNDROME); 46,XX (GONADAL DYSGENESIS, 46XX); 46,XY (GONADAL DYSGENESIS, 46,XY); and sex chromosome MOSAICISM; (GONADAL DYSGENESIS, MIXED). Their phenotypes range from female, through ambiguous, to male. This concept includes gonadal agenesis.
Compounds that interact with ANDROGEN RECEPTORS in target tissues to bring about the effects similar to those of TESTOSTERONE. Depending on the target tissues, androgenic effects can be on SEX DIFFERENTIATION; male reproductive organs, SPERMATOGENESIS; secondary male SEX CHARACTERISTICS; LIBIDO; development of muscle mass, strength, and power.
A birth defect due to malformation of the URETHRA in which the urethral opening is below its normal location. In the male, the malformed urethra generally opens on the ventral surface of the PENIS or on the PERINEUM. In the female, the malformed urethral opening is in the VAGINA.
Congenital conditions in individuals with a male karyotype, in which the development of the gonadal or anatomical sex is atypical.
Organs or parts of organs surgically formed from nearby tissue to function as substitutes for diseased or surgically removed tissue.
A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL.
The record of descent or ancestry, particularly of a particular condition or trait, indicating individual family members, their relationships, and their status with respect to the trait or condition.
Development of female secondary SEX CHARACTERISTICS in the MALE. It is due to the effects of estrogenic metabolites of precursors from endogenous or exogenous sources, such as ADRENAL GLANDS or therapeutic drugs.
A mutation caused by the substitution of one nucleotide for another. This results in the DNA molecule having a change in a single base pair.
Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.
In gonochoristic organisms, congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical. Effects from exposure to abnormal levels of GONADAL HORMONES in the maternal environment, or disruption of the function of those hormones by ENDOCRINE DISRUPTORS are included.
A characteristic symptom complex.
The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment.
A syndrome characterized by indifference to PAIN despite the ability to distinguish noxious from non-noxious stimuli. Absent corneal reflexes and INTELLECTUAL DISABILITY may be associated. Familial forms with autosomal recessive and autosomal dominant patterns of inheritance have been described. (Adams et al., Principles of Neurology, 6th ed, p1343)
A potent androgenic metabolite of TESTOSTERONE. It is produced by the action of the enzyme 3-OXO-5-ALPHA-STEROID 4-DEHYDROGENASE.
Defects in the SEX DETERMINATION PROCESS in 46, XY individuals that result in abnormal gonadal development and deficiencies in TESTOSTERONE and subsequently ANTIMULLERIAN HORMONE or other factors required for normal male sex development. This leads to the development of female phenotypes (male to female sex reversal), normal to tall stature, and bilateral streak or dysgenic gonads which are susceptible to GONADAL TISSUE NEOPLASMS. An XY gonadal dysgenesis is associated with structural abnormalities on the Y CHROMOSOME, a mutation in the GENE, SRY, or a mutation in other autosomal genes that are involved in sex determination.
Steroidal compounds related to TESTOSTERONE, the major mammalian male sex hormone. Testosterone congeners include important testosterone precursors in the biosynthetic pathways, metabolites, derivatives, and synthetic steroids with androgenic activities.

Assessment of the gonadotrophin-gonadal axis in androgen insensitivity syndrome. (1/139)

OBJECTIVE: To study the value of measuring serum luteinising hormone (LH), follicle stimulating hormone (FSH), testosterone, and dihydrotestosterone (DHT) in androgen insensitivity syndrome (AIS). DESIGN: Retrospective study of patients on a nationwide register of AIS. PATIENTS: Sixty one cases of AIS with androgen receptor (AR) dysfunction (abnormalities of the AR gene and/or abnormal AR binding) were divided into three age groups: infants, < 1 year old; children, 1-13 years old; and postpubertal, > 13 years old. MEASUREMENTS: Age, dose of human chorionic gonadotrophin (hCG) stimulation, pre-hCG and post-hCG serum testosterone values, serum DHT values, and serum LH and FSH values before and after LH releasing hormone (LHRH) stimulation. RESULTS: In 23 of 30 infants testosterone was within age related reference ranges; six were above this range. The median testosterone rise following variable dosage of hCG was 9.5 times the basal value. The increment was not related to the hCG dose, age, or basal concentration of testosterone. The median basal and stimulated testosterone:DHT ratios were 2.5 and 6.1, respectively. The median increment in DHT was 2.2-fold. Seventeen of 18 FSH and 11 of 19 LH measurements were within age related ranges in infants; in seven patients LH values were above the range. LHRH stimulation performed in 39 patients showed an exaggerated LH in all age groups. The FSH response was not exaggerated in children. CONCLUSION: Although a positive hCG test excludes biosynthetic defects of testosterone, an inadequate response does not exclude AIS. Basal LH and testosterone may not be raised during early infancy. An LHRH stimulation test might be useful for evaluating cases of suspected AIS presenting in mid-childhood.  (+info)

Direct androgenic regulation of calcitonin gene-related peptide expression in motoneurons of rats with mosaic androgen insensitivity. (2/139)

The spinal nucleus of the bulbocavernosus (SNB) and its target muscles, bulbocavernosus and levator ani (BC/LA), form a sexually dimorphic neuromuscular circuit whose development and maintenance are androgen-dependent. The mechanisms whereby androgen regulates gene expression in the SNB of adult rats are largely unknown, although a retrograde influence from the BC/LA muscles has been suggested to underlie the suppression of calcitonin gene-related peptide (CGRP) expression observed in SNB motoneurons after systemic androgen treatment. A mosaic paradigm was used to determine the site of action of androgen in the regulation of CGRP expression in SNB motoneurons. As a consequence of random X chromosome inactivation, androgenized female rats heterozygous for the tfm androgen receptor (AR) mutation (XwtXtfm-mosaics) express a mosaic of androgen-sensitive and androgen-insensitive motoneurons in the SNB, whereas the BC/LA target musculature appears to be uniformly sensitive to androgens. In adult mosaics, testosterone administration resulted in a reduction in the proportion of androgen-sensitive cells expressing CGRP, whereas no such reduction was observed in the androgen-insensitive population, indicating that neuronal AR plays an essential role in the neuromuscular regulation of CGRP expression in these motoneurons. This provides the first in vivo demonstration of AR regulation of gene expression unambiguously localized to a neuronal population.  (+info)

Point mutations in the steroid-binding domain of the androgen receptor gene of five Japanese patients with androgen insensitivity syndrome. (3/139)

We analyzed the androgen receptor (AR) gene in five Japanese patients diagnosed with androgen insensitivity syndrome (AIS). All AR genes from the five patients had single-nucleotide substitutions, which introduced a premature termination codon in three patients (Gln640, Arg752, and Gln640 and Trp751), and a single amino acid substitution in two patients (Arg831 to Gln, and Leu812 to Phe). All the mutations occurred in the steroid-binding domain, comprising exons D through G. The three patients with the premature termination codon(s) and the one patient with Arg831Gln were clinically diagnosed as having complete AIS, while the patient with Leu812Phe had a partial form of AIS. Pubic skin fibroblasts from four of the five patients did not show detectable androgen binding. These data on mutations that have not been reported previously, provide valuable information for the further characterization of structural and functional relationships in the steroid-binding domain of the AR protein.  (+info)

Coregulator small nuclear RING finger protein (SNURF) enhances Sp1- and steroid receptor-mediated transcription by different mechanisms. (4/139)

The small nuclear RING finger protein SNURF is not only a coactivator in steroid receptor-dependent transcription but also activates transcription from steroid-independent promoters. In this work, we show that SNURF, via the RING finger domain, enhances protein binding to Sp1 elements/GC boxes and interacts and cooperates with Sp1 in transcriptional activation. The activation of androgen receptor (AR) function requires regions other than the RING finger of SNURF, and SNURF does not influence binding of AR to cognate DNA elements. The zinc finger region (ZFR) together with the hinge region of AR are sufficient for contacting SNURF. The nuclear localization signal in the boundary between ZFR and the hinge region participates in the association of AR with SNURF, and a receptor mutant lacking the C-terminal part of the bipartite nuclear localization signal shows attenuated response to coexpressed SNURF. Some AR ZFR point mutations observed in patients with partial androgen insensitivity syndrome or male breast cancer impair the interaction of AR with SNURF and also render AR refractory to the transcription-activating effect of SNURF. Collectively, SNURF modulates the transcriptional activities of androgen receptor and Sp1 via different domains, and it may act as a functional link between steroid- and Sp1-regulated transcription.  (+info)

Pituitary-gonadal axis in male undermasculinisation. (5/139)

AIMS: To study the value of assessing serum concentrations of luteinising hormone (LH), follicle stimulating hormone (FSH), testosterone, and dihydrotestosterone (DHT) in patients with male undermasculinisation not caused by androgen insensitivity. METHODS: A retrospective study of a register of cases of male undermasculinisation (20 with abnormal testes, eight with 5alpha-reductase deficiency, three with testosterone biosynthetic defects, seven with Drash syndrome, and 210 undiagnosed). RESULTS: A human chorionic gonadotropin (hCG) stimulation test was performed in 66 of 185 children with male undermasculinisation. In 41 of 66 patients the dose of hCG was either 1000 U or 1500 U on three consecutive days. The rise in testosterone was related to basal serum testosterone and was not significantly different between the two groups. Testosterone:DHT ratio in patients with 5alpha-reductase deficiency was 12.5-72.8. During early infancy, baseline concentrations of LH and FSH were often within normal reference ranges. In patients with abnormal testes, median pre-LHRH (luteinising hormone releasing hormone) concentrations of LH and FSH were 2 and 6.4 U/l, respectively, and post-LHRH concentrations were 21 and 28 U/l. An exaggerated response to LHRH stimulation was observed during mid-childhood in children where the diagnosis was not clear and in all children with abnormal testes. CONCLUSIONS: The testosterone:DHT ratio following hCG stimulation is more reliable than the basal testosterone:DHT ratio in identifying 5alpha-reductase deficiency. During infancy, the LHRH stimulation test may be more reliable in identifying cases of male undermasculinisation due to abnormal testes than basal gonadotrophin concentrations.  (+info)

Tissue interaction in androgen response of embryonic mammary rudiment of mouse: identification of target tissue for testosterone. (6/139)

In the androgen response of the embryonic mammary rudiment of the mouse, both gland epithelium and surrounding mesenchyme are visibly involved. The question whether this is due to a direct action of testosterone on both tissues was investigated in experimental combination of mammary epithelium and mammary mesenchyme, derived either from normal or from androgen-insensitive (XTfm/Y) embryos. A typical androgen response occurred in combinations of androgen-insensitive epithelium with normal mesenchyme, whereas all combinations of normal epithelium with androgen-insensitive mesenchyme failed to respond. It is therefore concluded that only the mesenchyme of the mammary rudiment is the target tissue for testosterone, and that all changes in the gland epithelium, including its necrosis, are secondarily caused by testosterone-activated mesenchymal cells.  (+info)

Desert hedgehog (Dhh) gene is required in the mouse testis for formation of adult-type Leydig cells and normal development of peritubular cells and seminiferous tubules. (7/139)

Testes from adult and prepubertal mice lacking the Desert hedgehog (DHH:) gene were examined in order to describe further the role of Dhh in spermatogenesis because, in a previous report, DHH:-null male mice were shown to be sterile. Dhh is a signaling molecule expressed by Sertoli cells. Its receptor, patched (Ptc), has been previously localized to Leydig cells and is herein described as being localized also to peritubular cells. Two phenotypes of the mice were observed: masculinized (7.5% of DHH:-null males) and feminized (92.5%), both of which displayed abnormal peritubular tissue and severely restricted spermatogenesis. Testes from adult feminized animals lacked adult-type Leydig cells and displayed numerous undifferentiated fibroblastic cells in the interstitium that produced abundant collagen. The basal lamina, normally present between the myoid cells and Sertoli cells, was focally absent. We speculate that the abnormal basal lamina contributed to other characteristics, such as extracordal gonocytes, apolar Sertoli cells, and anastomotic seminiferous tubules. The two DHH:-null phenotypes described have common peritubular cell defects that may be indicative of the essential role of peritubular cells in development of tubular morphology, the differentiation of Leydig cells, and the ultimate support of spermatogenesis.  (+info)

Neuronal size in the spinal nucleus of the bulbocavernosus: direct modulation by androgen in rats with mosaic androgen insensitivity. (8/139)

The motoneurons of the spinal nucleus of the bulbocavernosus (SNB) and its target muscles, the bulbocavernosus and levator ani, form a sexually dimorphic circuit that is developmentally dependent on androgen exposure and exhibits numerous structural and functional changes in response to androgen exposure in adulthood. Castration of male adult rats causes shrinkage of SNB somata, and testosterone replacement reverses this effect, but the site at which androgen is acting to cause this change is undetermined. We exploited the X-chromosome residency of the androgen receptor (AR) gene to generate androgenized female rats that were heterozygous for the testicular feminization mutant (tfm) AR mutation and that, as a consequence of ontogenetic random X-inactivation, expressed a blend of androgen-sensitive wild-type cells and tfm-affected androgen-insensitive cells in the SNB. Chronic testosterone treatment of adult mosaics increased soma sizes only in androgen-competent wild-type SNB cells. The size of tfm-affected SNB somata in the same animals did not differ from the size of either the wild-type or tfm-affected SNB neurons in control mosaics that did not receive androgen treatment in adulthood. Because the muscle targets of the SNB are known to be uniformly androgen-sensitive in tfm mosaics, this mosaic analysis provides unambiguous evidence that androgenic effects on motoneuron soma size are mediated locally in the SNB. It is possible that the neuronal AR plays a permissive role in coordinating the actions of androgen.  (+info)

Androgen insensitivity syndrome is the most frequent cause of the male pseudohermaphrotidism and the third most frequent cause of primary amenorrhea (approximately 10% of the primary amenorrhea). [2,7] Three different types of AIS have been reported. [2,7] The three AIS phenotype classifications are: complete androgen insensitivity syndrome (CAIS), also called as testicular feminization syndrome, partial androgen insensitivity syndrome (PAIS), and mild androgen insensitivity syndrome (MAIS) also called as under-virilized male syndrome.[8] CAIS, the typical mode of presentation is in an adolescent female who has well developed breasts with a pubertal growth spurt but has no menarche and no or scanty growth of axillary and pubic hair. CAIS may also present in early infancy with the appearance of bilateral labial or inguinal swellings. Bilateral inguinal hernias are rare in girls and it has been estimated that 1-2% of such cases actually have CAIS. On the other hand if a female child shows inguinal ...
Androgen insensitivity syndrome is a condition that affects sexual development before birth and during puberty. People with this condition are genetically male, with one X chromosome and one Y chromosome in each cell. Because their bodies are unable to respond to certain male sex hormones (called androgens), they may have mostly female sex characteristics or signs of both male and female sexual development. There are three types of androgen insensitivity syndrome which vary in severity. There are different management options, so talk to your doctor about the best care plan if you or your child has been diagnosed with androgen insensitivity syndrome. For more information about the different types, please visit: mild androgen insensitivity syndrome; partial androgen insensitivity syndrome; or complete androgen insensitivity syndrome.. Androgen insensitivity syndrome is caused by mutations in the AR gene on the X chromosome. It is inherited (runs in families) as an X-linked recessive trait. ...
Partial androgen insensitivity syndrome (PAIS) is a condition that results in the partial inability of the cell to respond to androgens. The partial unresponsiveness of the cell to the presence of androgenic hormones impairs the masculinization of male genitalia in the developing fetus, as well as the development of male secondary sexual characteristics at puberty, but does not significantly impair female genital or sexual development. As such, the insensitivity to androgens is clinically significant only when it occurs in genetic males (i.e. individuals with a Y chromosome, or more specifically, an SRY gene). PAIS is one of three types of androgen insensitivity syndrome, which is divided into three categories that are differentiated by the degree of genital masculinization: complete androgen insensitivity syndrome (CAIS) is indicated when the external genitalia is that of a normal female, mild androgen insensitivity syndrome (MAIS) is indicated when the external genitalia is that of a normal ...
Mild androgen insensitivity syndrome (MAIS) is a condition that results in a mild impairment of the cells ability to respond to androgens. The degree of impairment is sufficient to impair spermatogenesis and / or the development of secondary sexual characteristics at puberty in males, but does not affect genital differentiation or development. Female genital and sexual development is not significantly affected by the insensitivity to androgens; as such, MAIS is only diagnosed in males. The clinical phenotype associated with MAIS is a normal male habitus with mild spermatogenic defect and / or reduced secondary terminal hair. MAIS is one of three types of androgen insensitivity syndrome, which is divided into three categories that are differentiated by the degree of genital masculinization: complete androgen insensitivity syndrome (CAIS) is indicated when the external genitalia is that of a normal female, mild androgen insensitivity syndrome (MAIS) is indicated when the external genitalia is ...

SUMMARY. Androgen insensitivity syndrome (Morris syndrome) occurs when target tissues are resistant to the effect of androgens resulting in phenotype with varying degrees of feminization ranging from male infertility to completely normal female external genitalia in patients with male karyotype. Androgen receptor (AR) following activation by androgenic hormones binds to DNA in cells of target tissues and induces biological changes leading to differentiation and development of male urogenital structures. To date, more than 800 mutations in AR gene have been described in patients with AIS with the majority being located in the ligand-binding domain. Here a detailed description of a family with two affected 46,XY females with complete androgen insensitivity is provided. Whole exome sequencing revealed a novel mutation in exon ...
Androgen insensitivity syndrome in children - What does androgen insensitivity syndrome mean? XY baby is a girl. Without testosterone (t), all babies develop as girls. So a child with 1 x & 1 y chromosome, who would normally be a boy, would develop as a girl if no t was present. In androgen insensitivity syndrome, the t is there, but the cells are insensitive to it, and dont respond, so its as if the t was not there at all. So an xy genetic boy baby is born looking like a normal healthy baby girl.
The partial androgen insensitivity syndrome occurs in 46,XY subjects with phenotypes ranging from perineoscrotal hypospadias with cryptorchidism and micropenis (mild undervirilisation) to clitoromegaly and partial labial fusion (marked undervirilisation). Within an affected family, wide variation in the degree of genital ambiguity between individuals can be seen. Two cousins of a previously reported subject who had severe genital ambiguity and partial androgen insensitivity were investigated. Neither of the cousins had genital abnormalities as marked as the index case, who also had qualitatively abnormal androgen binding and two mutations of the androgen receptor gene. Despite marked phenotypic differences between the index case and his cousins, similar androgen binding and the same androgen receptor mutations were shown in the cousins. Furthermore, one of the androgen receptor gene mutations has been shown in the mother and sister of one of the boys indicating that they are carriers. Thus ...

Androgen Insensitivity Syndrome (AIS) is the under-masculinization of individuals with XY sex chromosome karyotypes. A broad clinical spectrum of AIS exists, from mild to partial to complete AIS. Mouse models of complete AIS have been used to study aspects of sexual development, physiology, and behavioural outcomes in the absence of androgenic signaling. There is currently no animal model of partial AIS (PAIS), and the novel mouse strain described in this research satisfies the clinical description of human PAIS patients, appearing outwardly male with additional feminine characteristics. My research on the PAIS mouse model focuses on the anatomical features and endocrinology of this unique strain, and the role of partial androgen signaling as a cause of behavioural anxiety. -- Anatomically, PAIS male mice have similar body size and weight to wild-type (WT) males, but they have an intermediate anal-genital distance that is shorter than WT males, but longer than WT female mice. The PAIS males do ...

Partial androgen insensitivity syndrome (PAIS) is usually spotted soon after birth because the genitals have an unusual appearance.. Complete androgen insensitivity syndrome (CAIS) isnt usually diagnosed at birth because the genitals look normal for a girl, although the condition may be picked up if the child develops a hernia.. Hernias are where an internal part of the body pushes through a weakness in the surrounding tissue. They can occur in babies with CAIS as a result of the testicles failing to move from the tummy into the scrotum.. When the baby has an operation to repair the hernia, the surgeon may find the testicles inside the hernia or in the tummy, and tests may be arranged to check for CAIS.. If a baby with CAIS doesnt develop a hernia, the condition may go undiagnosed until puberty, when she doesnt start having periods and doesnt develop pubic and underarm hair.. Read more about the symptoms of AIS and types of AIS.. ...
Androgen insensitivity syndrome (AIS), also referred to as androgen resistance syndrome, is a set of disorders of sex development caused by mutations of the gene encoding the androgen receptor. The set of resulting disorders varies according to the structure and sensitivity of the abnormal receptor. Most forms of AIS involve a variable degree of undervirilization and/or infertility in people genetically XY.
In the domestic horse; failure of normal masculinization and virilization due to deficiency of androgenic action leads to a specific disorder of sexual development known as equine androgen insensitivity syndrome (AIS). Affected individuals appear to demonstrate an incoherency between their genetic sex and sexual phenotype; i.e., XY-sex chromosome constitution and female phenotypic appearance. AIS is well documented in humans. Here we report the finding of two novel genetic variants for the AR-gene identified in a Tennessee Walking Horse and a Thoroughbred horse mare; each in individual clinical cases of horse AIS syndrome.

Male Pseudohermaphroditism/ Androgen Insensitivity Syndrome. Children with complete androgen insensitivity syndrome or CAIS are the counterparts to XX CAH children. Their external genitalia take the typical female form, but internally they lack a uterus, and in the place where one would ordinarily find ovaries, they have internal testes. Because their bodies do not respond to testosterone, they grow up to develop very feminine secondary sexual characteristics at puberty, though they will never have menstrual periods. Despite their typically-female appearance, doctors call these individuals male pseudohermaphrodites because they have testes. However, in contrast to the treatment of children with CAH, doctors do not go on to say that they CAIS children have malformed penises that must be surgically altered to fit their true sex. Instead of urging genital reconstruction, they tell parents to raise their CAIS children as girls, warn parents that their internal testes could possibly present a ...

Boys with genetically confirmed PAIS are likely to have a poorer clinical outcome than those with XY DSD, with normal T synthesis, and without an identifiable AR mutation. Routine genetic analysis of AR to confirm PAIS informs long-term prognosis and management.
The table of Judy Knights alleged genetic markers is fairly useless without context. I agree that having male haplogroup markers makes no sense as presumably Judy Knight is female and should lack a Y chromosome. There is a condition called CAIS (complete androgen insensitivity syndrome) that results from a defect in the RH gene. A person with CAIS is morphologically female due to the bodys inability to respond to androgens (male hormones), yet that person is actually a male despite having a female form. The catch here is that people with CAIS are infertile and apparently Judy Knight has produced offspring. I am not an expert, but I am not aware of another way to possess a Y chromosome needed to carry the markers cited in the table above and not be morphologically male ...

Cryptorchidism is associated with a several-fold higher risk of GCT. Abdominal cryptorchid testes are at a higher risk than inguinal cryptorchid testes. Orchiopexy should be performed before puberty, if possible. Early orchiopexy reduces the risk of GCT and improves the ability to save the testis. An abdominal cryptorchid testis that cannot be brought into the scrotum should be removed. Approximately 2% of men with GCTs of one testis will develop a primary tumor in the other testis. Testicular feminization syndromes increase the risk of testicular GCT, and Klinefelters syndrome is associated with mediastinal GCT. ...
When a child is born with complete AIS or CAIS, the baby will probably outwardly appear as a completely normal female. She will typically be raised as a woman and may have internal gonads that produce testosterone, which the brain alters to estrogen for her. Since male hormones are responsible for sexual virilization or facial, pubic and underarm hair, a person with CAIS may have little, if any. Some of these women do not even find out about having AIS until in their late teens or after puberty when the diagnosis is established because of a lack of menses or a period. ...
AR gene, the only gene known to be associated with androgen insensitivity syndrome, detects mutations in more than 95% of probands with complete androgen insensitivity and is available clinically. Its yield in individuals with partial or mild forms of AIS is unknown.. Management. To prevent testicular malignancy, treatment of CAIS includes either removal of the testes after puberty when feminization is complete or prepubertal gonadectomy accompanied by estrogen replacement therapy. Additional treatment for CAIS may include vaginal dilatation to avoid dyspareunia. Treatment of PAIS in individuals with predominantly female genitalia is similar to treatment of CAIS but is more likely to include prepubertal gonadectomy to help avoid increasing clitoromegaly at the time of puberty. In individuals with PAIS and ambiguous or predominantly male genitalia, parents and healthcare professionals should assign sex of rearing as early as possible in infancy. Those individuals with PAIS who are raised as males ...

Background on Disease Markers The single nucleotide polymorphism (SNP), 137852571, that is being examined in this experiment is linked with Androgen Insensitivity Syndrome and Kennedy Spinal and Bulbar Muscular Atrophy. Androgen Insensitivity Syndrome occurs when a person who is genetically male (who has one X and one Y chromosome) is resistant to male hormones (called androgens). As a result, the person has some or all of the physical traits of a female, but the genetic makeup of a male. The mutation on the X chromosome makes the body unable to respond to the hormones that produce a male appearance. Kennedy Spinal and Bulbar Muscular Atrophy is a debilitating neurodegenerative disease resulting in muscle cramps and progressive weakness due to degeneration of motor neurons in the brain stem and spinal cord. The SNP is located on the X chromosome and affects the gene AR, the gene is inherited in an x-linked recessive manner therefore only males can be fully affected by the mutation and females ...

N2 - We have investigated the basis of androgen resistance in seven unrelated individuals with complete testicular feminization or Reifenstein syndrome caused by single amino acid substitutions in the hormone-binding domain of the androgen receptor. Monolayer-binding assays of cultured genital skin fibroblasts demonstrated absent ligand binding, qualitative abnormalities of androgen binding, or a decreased amount of qualitatively normal receptor. The consequences of these mutations were examined by introducing the mutations by site-directed mutagenesis into the androgen receptor cDNA sequence and expressing the mutant cDNAs in mammalian cells. The effects of the amino acid substitutions on the binding ...
The November 2006 editorial about treatment of children born with ambiguous genitalia proceeds from a problematic premise, and goes on to imbue questions about elective genitoplasty with a rhetoric of optimism that could be misleading to distraught parents.. Dr. Rivkees argues that surgical gender reversal no longer occurs because 46,XX infants with CAH are typically assigned as female regardless of virilization, and 46,XY infants with testes and microphallus are typically assigned as male. However, gender identity development in children born with atypical genitalia is poorly understood1. It is certain that neither chromosomes nor gonads decisively determine gender. Patients with complete or partial androgen insensitivity syndrome (AIS), for example, commonly develop a female gender identity; but not always2. Parents who are considering irreversibly altering their childs genitals need to understand this uncertainty in order to make an informed decision. Whether or not gender assignment ...
After reading the Daily Telegraph of London, I read some of the 299 comments and per usual everybody has an opinion about something they know nothing about. All speculative! As a Urologist, who lectures on this very subject to medical doctors, let me tell you what I think I know from reading the AP from Pretoria, SA. Caster Semenya has a probable genetic Disorder of Sexual Development known as Partial Androgen Insensitivity Syndrome, probably Grade 5 or 6, where the external genitalia are female-like and the internal genitalia are vestigial testes, which produce Testosterone and Estrogen. I say probable because we cannot know if she has any ovarian tissue mixed with the testis tissue until these vestigial organs are examined under the microscope by a pathologist. This will probably never happen, unless it is presented to her as a condition for receiving female hormones. At this moment everyone is assuming she is an XY woman. Now somebody said she had three times the normal female Testosterone ...
As described recently (Nirdé et al., 2001), the region surrounding Gly708 in the hAR seems to be crucial for the stabilization of the active hAR conformation. The sequence alignment of the hAR revealed that this glycine residue is well conserved, as it is in human progesterone receptor and human glucocorticoid receptor. This suggests the key role of this amino acid in the functionality of nuclear receptors, although it should be noted that hMR and hER possess an alanine at the corresponding position. Furthermore, an AR gene mutation was detected by single-strand conformation polymorphism in codon 708, leading to an amino acid substitution Gly708A (Hiort et al., 1994; Albers et al., 1997). This point mutation causes a partial androgen insensitivity syndrome clinically characterized by undervirilization in 46XY male patients.. We previously showed (Auzou et al., 2000) that the Ala773Gly substitution in hMR was critical for generating agonist mineralocorticoid activity in the 11β-substituted ...
Hermaphrodite is used in older literature to describe any person whose physical characteristics do not neatly fit male or female classifications, but some people advocate to replace the term with intersex.[25][26] Intersex describes a wide variety of combinations of what are considered male and female biology. Intersex biology may include, for example, ambiguous-looking external genitalia, karyotypes that include mixed XX and XY chromosome pairs (46XX/46XY, 46XX/47XXY or 45X/XY mosaic). Clinically, medicine currently describes intersex people as having disorders of sex development, a term vigorously contested.[27][28] This is particularly because of a relationship between medical terminology and medical intervention.[29] Intersex civil society organizations, and many human rights institutions,[30][31] have criticized medical interventions designed to make intersex bodies more typically male or female. Some people who are intersex, such as some of those with androgen insensitivity syndrome, ...
Key points: Patients with disorders of sex development (DSDs) are at an increased risk of malignant germ cell tumors (GCTs). In adulthood, the partial form of androgen insensitivity syndrome confers the greatest risk of developing malignant GCTs. Gonadoblastoma is the most common gonadal GCT arising in patients with DSDs. Despite being a benign neoplasm, it can undergo malignant transformation in up to 60% of patients with a DSD. Oncologic treatment in patients with disorders of sex development and malignant GCTs does not differ from the standard treatment for testicular GCTs. Treatment of patients with DSDs requires a multidisciplinary team, including a psychiatric, genetic, and reproductive assessment as well as the involvement of an ethics committee. An early diagnosis of DSDs is crucial to avoid the development of potentially serious complications in adulthood. ...
If this is Androgen Insensitivity Syndrome (AIS), she is not a man because her body does not respond to testosterone she is producing, but there is no space, at the end of the day, for an XY female athlete.Now, take the plurality of genders (which by no means is an exhaustive list) and take the numbers of choromosomal patterns (which again is not an exhaustive list) and create all sorts of permutations and combinations and see the number you come up with. How can then you clearly say this is a man and this a woman? Should people with all of these syndromes not be allowed to play? Should they not be allowed to live? The violence of such archaic notions of sex, uninformed by science, and unethical in practice are clear. Santhi tried to kill herself because she was an athlete, a brilliant athlete, who had won for her country one of the few medals that it manages to win every four years, who had been shamed and stripped of her hard-earned and well-deserved medal because of some outdated and ...

Despite the low prevalence of primary amenorrhea, a prompt, comprehensive assessment by a specialist in reproductive medicine is warranted, as amenorrhea is often the presenting sign of an underlying reproductive disorder. A delay in diagnosis and treatment may adversely impact the long-term future of such patients. For example, an adolescent with androgen insensitivity syndrome requires counseling for eventual removal of gonads because these patients carry up to about a 30% risk of gonadal neoplasms. In polycystic ovary syndrome and hyperinsulinemia, behavioral and dietary modifications may prevent subsequent cardiovascular disease. [4] Verp MS, Simpson JL.

Androgens are central to sexual differentiation and the maintenance of male secondary sexual characteristics and functions. Individuals with inactivating mutations of their androgen receptor (AR) (androgen insensitivity syndromes (AIS)) are phenotypically female in appearance and behavior and lack male sex accessory organs (prostate, seminal vesicles and Cowpers glands) despite the presence of testes, high levels of testosterone and a Y chromosome [1]. The effects of androgens are cell-specific and developmental stage-specific. For instance, castration of an adult male does not change the external genitalia or voice pitch, but causes a profound involution of the prostate, particularly in the epithelial compartment [2,3]. The exquisite sensitivity of prostatic epithelial cells to androgens has been exploited therapeutically in the management of prostate cancer [4].. The mechanisms underlying the temporal and tissue-specific effects of androgens are not understood. Like all steroid hormones, ...
AIS is inherited as an X-linked recessive disorder, the result of a defect in the androgen-receptor gene. Chromosome analysis is 46,XY. 23 The androgen-receptor gene was cloned by several groups in 1988, and is located on the X chromosome at Xq11-12.37 The gene is 90 kb in length and consists of eight exons that encode the three domains of the receptor (see Fig. 3).11,12,13,14,38 Exon 1 encodes the transcription regulation domain. This region includes polymorphic CAG repeats, which aid in restriction fragment length polymorphism (RFLP) diagnosis. Exons 2 and 3 encode the DNA-binding domains; exons 4 to 8 encode the androgen-binding domains. Many mutations involving the androgen-receptor gene have been identified.39,40,41,42,43 Like most genes, molecular heterogeneity exists among affected persons. Surprisingly, however, both receptor-positive and receptor-negative persons with complete AIS seem indistinguishable clinically.. Approximately 70% of cases studied have shown a mutation in the ...

I once was explaining this to a class, and after seeing this textbook photo, a student asked Couldnt that lead to homosexuality? I initially thought she meant that, being XY, theyd want to have sex with women, and that would make them lesbians. It took a few minutes of rather confusing discussion before I realized that she meant that theyd probably have sex with guys, and being XY, that would make them gay. I think the class found it fairly disturbing that their terminology wasnt working in this instance.. Androgen insensitivity and hypospadias are examples of the range of conditions known as intersex. The term itself reflects the general discomfort of people toward any admission that gender is not an absolute dichotomy. And of course, that discomfort exists in part because a large majority of individuals do cluster close to the ends of the continuum, at least when it comes to genital morphology.. When you consider, as discussed in the recent New York Times essay on this issue, that ...
