Gonadal Dysgenesis: 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.Gonadal Dysgenesis, 46,XY: 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.Gonadal Dysgenesis, Mixed: A type of defective gonadal development in patients with a wide spectrum of chromosomal mosaic variants. Their karyotypes are of partial sex chromosome monosomy resulting from an absence or an abnormal second sex chromosome (X or Y). Karyotypes include 45,X/46,XX; 45,X/46,XX/47,XXX; 46,XXp-; 45,X/46,XY; 45,X/47,XYY; 46,XYpi; etc. The spectrum of phenotypes may range from phenotypic female to phenotypic male including variations in gonads and internal and external genitalia, depending on the ratio in each gonad of 45,X primordial germ cells to those with normal 46,XX or 46,XY constitution.Gonadoblastoma: A complex neoplasm composed of a mixture of gonadal elements, such as large primordial GERM CELLS, immature SERTOLI CELLS or GRANULOSA CELLS of the sex cord, and gonadal stromal cells. Gonadoblastomas are most often associated with gonadal dysgenesis, 46, XY.Turner Syndrome: A syndrome of defective gonadal development in phenotypic females associated with the karyotype 45,X (or 45,XO). Patients generally are of short stature with undifferentiated GONADS (streak gonads), SEXUAL INFANTILISM, HYPOGONADISM, webbing of the neck, cubitus valgus, elevated GONADOTROPINS, decreased ESTRADIOL level in blood, and CONGENITAL HEART DEFECTS. NOONAN SYNDROME (also called Pseudo-Turner Syndrome and Male Turner Syndrome) resembles this disorder; however, it occurs in males and females with a normal karyotype and is inherited as an autosomal dominant.Sex-Determining Region Y Protein: A transcription factor that plays an essential role in the development of the TESTES. It is encoded by a gene on the Y chromosome and contains a specific HMG-BOX DOMAIN that is found within members of the SOX family of transcription factors.Gonadal Dysgenesis, 46,XX: The 46,XX gonadal dysgenesis may be sporadic or familial. Familial XX gonadal dysgenesis is transmitted as an autosomal recessive trait and its locus was mapped to chromosome 2. Mutation in the gene for the FSH receptor (RECEPTORS, FSH) was detected. Sporadic XX gonadal dysgenesis is heterogeneous and has been associated with trisomy-13 and trisomy-18. These phenotypic females are characterized by a normal stature, sexual infantilism, bilateral streak gonads, amenorrhea, elevated plasma LUTEINIZING HORMONE and FSH concentration.Dermatoglyphics: The study of the patterns of ridges of the skin of the fingers, palms, toes, and soles.Disorders of Sex Development: 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.Thyroid Dysgenesis: Defective development of the THYROID GLAND. This concept includes thyroid agenesis (aplasia), hypoplasia, or an ectopic gland. Clinical signs usually are those of CONGENITAL HYPOTHYROIDISM.Sex Chromosome Aberrations: Abnormal number or structure of the SEX CHROMOSOMES. Some sex chromosome aberrations are associated with SEX CHROMOSOME DISORDERS and SEX CHROMOSOME DISORDERS OF SEX DEVELOPMENT.46, XY Disorders of Sex Development: Congenital conditions in individuals with a male karyotype, in which the development of the gonadal or anatomical sex is atypical.Karyotyping: Mapping of the KARYOTYPE of a cell.Mosaicism: The occurrence in an individual of two or more cell populations of different chromosomal constitutions, derived from a single ZYGOTE, as opposed to CHIMERISM in which the different cell populations are derived from more than one zygote.Sex Determination Analysis: Validation of the SEX of an individual by inspection of the GONADS and/or by genetic tests.Frasier Syndrome: A syndrome characterized by CHRONIC KIDNEY FAILURE and GONADAL DYSGENESIS in phenotypic females with karyotype of 46,XY or female individual with a normal 46,XX karyotype. It is caused by donor splice-site mutations of Wilms tumor suppressor gene (GENES, WILMS TUMOR) on chromosome 11.Dysgerminoma: A malignant ovarian neoplasm, thought to be derived from primordial germ cells of the sexually undifferentiated embryonic gonad. It is the counterpart of the classical seminoma of the testis, to which it is both grossly and histologically identical. Dysgerminomas comprise 16% of all germ cell tumors but are rare before the age of 10, although nearly 50% occur before the age of 20. They are generally considered of low-grade malignancy but may spread if the tumor extends through its capsule and involves lymph nodes or blood vessels. (Dorland, 27th ed; DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1646)Sexual Development: The processes of anatomical and physiological changes related to sexual or reproductive functions during the life span of a human or an animal, from FERTILIZATION to DEATH. These include SEX DETERMINATION PROCESSES; SEX DIFFERENTIATION; SEXUAL MATURATION; and changes during AGING.Neoplasms, Gonadal Tissue: Neoplasms composed of tissues of the OVARY or the TESTIS, not neoplasms located in the ovaries or testes. Gonadal tissues include GERM CELLS, cells from the sex cord, and gonadal stromal cells.X Chromosome: The female sex chromosome, being the differential sex chromosome carried by half the male gametes and all female gametes in human and other male-heterogametic species.Clitoris: An erectile structure homologous with the penis, situated beneath the anterior labial commissure, partially hidden between the anterior ends of the labia minora.Genes, sry: The primary testis-determining gene in mammalians, located on the Y CHROMOSOME. It codes for a high mobility group box transcription factor (TRANSCRIPTION FACTORS) which initiates the development of the TESTES from the embryonic GONADS.Y Chromosome: The male sex chromosome, being the differential sex chromosome carried by half the male gametes and none of the female gametes in humans and in some other male-heterogametic species in which the homologue of the X chromosome has been retained.Gonads: The gamete-producing glands, OVARY or TESTIS.Genitalia: The external and internal organs related to reproduction.Sex Determination Processes: The mechanisms by which the SEX of an individual's GONADS are fixed.Steroidogenic Factor 1: A transcription factor and member of the nuclear receptor family NR5 that is expressed throughout the adrenal and reproductive axes during development. It plays an important role in sexual differentiation, formation of primary steroidogenic tissues, and their functions in post-natal and adult life. It regulates the expression of key steroidogenic enzymes.Sex Chromosomes: The homologous chromosomes that are dissimilar in the heterogametic sex. There are the X CHROMOSOME, the Y CHROMOSOME, and the W, Z chromosomes (in animals in which the female is the heterogametic sex (the silkworm moth Bombyx mori, for example)). In such cases the W chromosome is the female-determining and the male is ZZ. (From King & Stansfield, A Dictionary of Genetics, 4th ed)DAX-1 Orphan Nuclear Receptor: An orphan nuclear receptor that is implicated in regulation of steroidogenic pathways. It is unlike most orphan nuclear receptors in that it appears to lack an essential DNA-binding domain and instead acts as a transcriptional co-repressor. Mutations in the gene Dax-1 cause congenital adrenal hypoplasia.Chromosome Banding: Staining of bands, or chromosome segments, allowing the precise identification of individual chromosomes or parts of chromosomes. Applications include the determination of chromosome rearrangements in malformation syndromes and cancer, the chemistry of chromosome segments, chromosome changes during evolution, and, in conjunction with cell hybridization studies, chromosome mapping.Amenorrhea: Absence of menstruation.Testis: The male gonad containing two functional parts: the SEMINIFEROUS TUBULES for the production and transport of male germ cells (SPERMATOGENESIS) and the interstitial compartment containing LEYDIG CELLS that produce ANDROGENS.Eye Abnormalities: Congenital absence of or defects in structures of the eye; may also be hereditary.Phenotype: The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment.Anterior Eye Segment: The front third of the eyeball that includes the structures between the front surface of the cornea and the front of the VITREOUS BODY.SOX9 Transcription Factor: A SOXE transcription factor that plays a critical role in regulating CHONDROGENESIS; OSTEOGENESIS; and male sex determination. Loss of function of the SOX9 transcription factor due to genetic mutations is a cause of CAMPOMELIC DYSPLASIA.Agenesis of Corpus Callosum: Birth defect that results in a partial or complete absence of the CORPUS CALLOSUM. It may be isolated or a part of a syndrome (e.g., AICARDI'S SYNDROME; ACROCALLOSAL SYNDROME; ANDERMANN SYNDROME; and HOLOPROSENCEPHALY). Clinical manifestations include neuromotor skill impairment and INTELLECTUAL DISABILITY of variable severity.Mutation: 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.Transcription Factors: Endogenous substances, usually proteins, which are effective in the initiation, stimulation, or termination of the genetic transcription process.Pedigree: 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.Dibutyl Phthalate: A plasticizer used in most plastics and found in water, air, soil, plants and animals. It may have some adverse effects with long-term exposure.Hybridization, Genetic: The genetic process of crossbreeding between genetically dissimilar parents to produce a hybrid.Congenital Hypothyroidism: A condition in infancy or early childhood due to an in-utero deficiency of THYROID HORMONES that can be caused by genetic or environmental factors, such as thyroid dysgenesis or HYPOTHYROIDISM in infants of mothers treated with THIOURACIL during pregnancy. Endemic cretinism is the result of iodine deficiency. Clinical symptoms include severe MENTAL RETARDATION, impaired skeletal development, short stature, and MYXEDEMA.Testicular Diseases: Pathological processes of the TESTIS.DNA-Binding Proteins: Proteins which bind to DNA. The family includes proteins which bind to both double- and single-stranded DNA and also includes specific DNA binding proteins in serum which can be used as markers for malignant diseases.Oophoritis: Inflammation of the OVARY, generally caused by an ascending infection of organisms from the endocervix.

(1/18) Cytogenetic and molecular study of a premature male infant with 46,XX derived from ICSI: case report.

We investigated the aetiology of the male phenotype in a premature infant derived from ICSI with a 46,XX karyotype. A karyotypically normal couple underwent ICSI because of obstructive azoospermia in the male partner. Sperm were retrieved by testicular sperm extraction (TESE), cryopreserved, and later used for ICSI. The pregnancy after ICSI ended at 20 weeks. A normal-appearing male was delivered but he did not survive. Umbilical cord blood and placenta were sampled and used for molecular and cytogenetic investigation. The 46,XX karyotype from G-banding in this male infant correlated to a balanced female comparative genomic hybridization (CGH) profile in placental tissue. No PCR amplification of SRY on the p arm of the Y chromosome was observed while fluorescence in-situ hybridization (FISH) with the SRY probe also could not detect the gene in cord blood or placental tissues. CGH and FISH, with X and Y centromeric probes, failed to detect mosaicism in the trophoblast, stroma and amnion. Skewed X-chromosome inactivation (81%) was found in the chorionic villi. The molecular and cytogenetic studies indicated a 46,XX male infant without the SRY gene or 46,XX/XY mosaicism. The possible mechanism in this SRY-negative XX male by ICSI is discussed.  (+info)

(2/18) Chromosomal instability in two siblings with gonad deficiency: case report.

Non-random de novo autosomal chromosomal rearrangements have not been shown to cause exocrine or gonadal dysfunction. We report on two siblings, a brother and a sister, both with de novo chromosomal rearrangements and gonadal deficiency including premature ovarian failure. They had normal phenotypes without additional manifestations of known chromosomal breakage syndromes (except for the gonadal dysfunction) and normal alpha-fetoprotein dosage level. The association of sperm abnormalities in the brother and ovarian dysfunction in the sister suggested an increased spontaneous chromosomal instability. Since the co-occurrence of chromosomal anomalies and reproductive failures may not be coincidental, we performed repeated chromosomal analysis of peripheral blood lymphocytes prior to proposing ICSI for IVF (for the brother). In both sibs, infertility was associated with random and non-random de novo autosomal chromosomal abnormalities. We discuss the possible relationship between these unusual clinical and cytogenetic features and their potential links to ataxia-telangiectasia.  (+info)

(3/18) SRY-negative 46,XX male with normal genitals, complete masculinization and infertility.

XX maleness is a rare syndrome with a frequency of 1 in 20,000-25,000 males. XX males exist in different clinical categories with ambiguous genitalia or partially to fully mature male genitalia, in combination with complete or incomplete masculinization. In this study, we report a case of SRY-negative XX male with complete masculinization but infertility. The patient had fully mature male genitalia with descended but small testes and no signs of undervirilization. PCR analysis for SRY, ZFY, Amelogenin, AZFa, AZFb, AZFc genes, a pair of primers from heterochromatic region and six Y-STRs showed the absence of any Y-chromosome-derived material. Absence of SRY gene was confirmed by three independent PCRs for each of two sets of primers covering an increasing length of the gene. Sequence analysis of the coding regions of SOX9 and DAX1 genes did not reveal any mutation. Real-time PCR assay revealed normal copy number for SOX9 gene. Microsatellite analysis showed no evidence of 17q (SOX9 gene) or 22q duplication. Genotyping with X-STRs ruled out the possibility of any deletion on X chromosome. Development of the male phenotype in the absence of SRY probably resulted from the loss of function mutation in some unknown sex-determining gene, which normally inhibits the male pathway, or from a gain of function mutation in a gene downstream to SRY in male pathway.  (+info)

(4/18) Quality of life in 70 women with disorders of sex development.

OBJECTIVE: The aim of this study was to assess the quality of life and psychosocial well-being in women with disorders of sex development (DSD). DESIGN: An open case-control study. METHODS: Social and psychiatric information was collected via a structured interview from 70 Danish women diagnosed with DSD, 70 controls matched on sex, age, and school education, and six women with isolated genital malformations. Quality of life and mental distress were assessed by 'Quality of Life-Assessment of Growth Hormone Deficiency in Adults' (QoL-AGHDA) and three symptom scales from the 'Hopkins Symptom Checklist' (SCL-90-R; i.e. somatization, depression, and anxiety) respectively. For both measures, higher scores reflected poorer outcomes. RESULTS: Present relationships and having children were less frequent in patients than in controls (P = 0.02 and P < 0.001 respectively). Previous suicidal thoughts (P = 0.002) and a higher frequency of psychological/psychiatric counseling for severe problems (P = 0.06) were more frequently reported in patients than in controls. The mean QoL-AGHDA score was significantly higher in patients than in controls (5.5 vs 2.9; P = 0.002), especially for congenital adrenal hyperplasia (CAH) females (P = 0.01) and virilized 46,XX and 46,XY females (P = 0.04). The total SCL score was higher in patients than in controls (mean 23.2 vs 20.0), reaching significance for anxiety (mean 6.3 vs 4.3, P = 0.03) with highest score in CAH (P = 0.01). CONCLUSION: An impaired quality of life and more affective distress were observed especially in CAH patients and virilized 46,XX and 46,XY females.

OBJECTIVE: To assess sexual function in women with spontaneous 46,XX primary ovarian insufficiency after at least 3 months of a standardized hormone replacement regimen. DESIGN: Cross-sectional cohort, controlled. SETTING: National Institutes of Health Clinical Research Center. PATIENT(S): Women with primary ovarian insufficiency (n = 143) and regularly menstruating controls (n = 70). INTERVENTION(S): Self-administered questionnaires, 100 microg/day E(2) patch, oral medroxyprogesterone acetate 10 mg for 12 days each month for patients. MAIN OUTCOME MEASURE(S): Derogatis Interview for Sexual Function Self-Report (DISF-SR). RESULT(S): Women with primary ovarian insufficiency had significantly lower DISF-SR composite scores compared with control women. Their serum total testosterone levels were significantly correlated with DISF-SR composite score, although this accounted for only 4% of the variance in this measure. Patients with testosterone levels below normal tended to have lower DISF-SR composite scores. Of patients with primary ovarian insufficiency, 9 of 127 (7%) scored below the second percentile on the composite sexual function score, compared with 1 of 49 control women (2%). CONCLUSION(S): As assessed by the DISF-SR, sexual function is in the normal range for most young women with 46,XX spontaneous primary ovarian insufficiency who are receiving physiologic E(2) replacement. However, as a group, these young women score significantly lower on this sexual function scale than control women.  (+info)

  • partial
  • A standard karyotype can be completed to cytogenetically determine that an individual with a partial or complete male phenotype has a XX genotype. (wikipedia.org)
  • undergo
  • Apparently either the germ cells do not form or interact with the gonadal ridge or undergo accelerated atresia so that at the end of childhood only a streak gonad is present, unable to induce pubertal changes. (wikipedia.org)
  • Mutations
  • Masculinization of SRY-negative XX males is dependent upon which genes have mutations and at what point in development these mutations occur. (wikipedia.org)
  • testes
  • Most XX males have small testes, are sterile, and have an increase in maldescended testicles compared to XY males. (wikipedia.org)
  • DAX1 represses masculinizing genes, therefore, if there is a loss of function of DAX1 then testes can develop in an XX individual. (wikipedia.org)
  • Fertility
  • Although fertility is possible in true hermaphrodites, there has yet to be a documented case where both gonadal tissues function, contrary to the misconception that hermaphrodites can impregnate themselves. (wikipedia.org)
  • development
  • For this reason, in gonadal dysgenesis the accompanying hormonal failure also prevents the development of secondary sex characteristics in either sex, resulting in a sexually infantile female appearance and infertility. (wikipedia.org)
  • male
  • When the X with the SRY gene combines with a normal X from the mother during fertilization, the result is an XX male. (wikipedia.org)
  • On average, the appearance of XX males differs from that of an XY male in that they are smaller in height and weight. (wikipedia.org)
  • Some XX male individuals have decreased amounts of body hair and decreased libido. (wikipedia.org)
  • In rare cases, an XX male does not have the SRY gene. (wikipedia.org)
  • To be female, one needs to be (XX), whereas to be a male, (XY) is needed. (wikipedia.org)
  • characteristics
  • According to research at the University of Oklahoma health science centers, despite XX males exhibiting feminine characteristics, their behaviours are usually representative of masculinity in their culture. (wikipedia.org)
  • possible
  • We performed a prospective multicentre study to explore the possible aetiological basis of 46,XY DSD in the Hong Kong Chinese population. (hkmj.org)
