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.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.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.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.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.46, XX Disorders of Sex Development: Congenital conditions in individuals with a female karyotype, in which the development of the gonadal or anatomical sex is atypical.Hypospadias: 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.Sex Reassignment Procedures: Clinical treatments used to change the physiological sexual characteristics of an individual.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.Virilism: Development of male secondary SEX CHARACTERISTICS in the FEMALE. It is due to the effects of androgenic metabolites of precursors from endogenous or exogenous sources, such as ADRENAL GLANDS or therapeutic drugs.46, XX Testicular Disorders of Sex Development: Congenital conditions in individuals in which male GONADS develop in a genetic female (female to male sex reversal).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.Ovotesticular Disorders of Sex Development: Conditions of sexual ambiguity in which the individual possesses gonadal tissues of both sexes, tissues from the OVARY and the TESTIS. There can be a testis on one side and an ovary on the other (lateral), or there may be combined ovarian and testicular tissue (ovotestes) on each side (bilateral). The karyotype may be 46,XX; 46,XY; or a mosaic of 46,XX/46,XY. These disorders have historically been called true hermaphroditism.Androgen-Insensitivity Syndrome: 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.Antley-Bixler Syndrome Phenotype: An inherited condition characterized by multiple malformations of CARTILAGE and bone including CRANIOSYNOSTOSIS; midface hypoplasia; radiohumeral SYNOSTOSIS; CHOANAL ATRESIA; femoral bowing; neonatal fractures; and multiple joint CONTRACTURES and, occasionally, urogenital, gastrointestinal or cardiac defects. In utero exposure to FLUCONAZOLE, as well as mutations in at least two separate genes are associated with this condition - POR (encoding P450 (cytochrome) oxidoreductase (NADPH-FERRIHEMOPROTEIN REDUCTASE)) and FGFR2 (encoding FIBROBLAST GROWTH FACTOR RECEPTOR 2).Sex Determination Analysis: Validation of the SEX of an individual by inspection of the GONADS and/or by genetic tests.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.Psychosexual Development: The stages of development of the psychological aspects of sexuality from birth to adulthood; i.e., oral, anal, genital, and latent periods.Genitalia: The external and internal organs related to reproduction.Sex Chromosome Disorders of Sex Development: Congenital conditions of atypical sexual development associated with abnormal sex chromosome constitutions including MONOSOMY; TRISOMY; and MOSAICISM.Adrenal Hyperplasia, Congenital: A group of inherited disorders of the ADRENAL GLANDS, caused by enzyme defects in the synthesis of cortisol (HYDROCORTISONE) and/or ALDOSTERONE leading to accumulation of precursors for ANDROGENS. Depending on the hormone imbalance, congenital adrenal hyperplasia can be classified as salt-wasting, hypertensive, virilizing, or feminizing. Defects in STEROID 21-HYDROXYLASE; STEROID 11-BETA-HYDROXYLASE; STEROID 17-ALPHA-HYDROXYLASE; 3-beta-hydroxysteroid dehydrogenase (3-HYDROXYSTEROID DEHYDROGENASES); TESTOSTERONE 5-ALPHA-REDUCTASE; or steroidogenic acute regulatory protein; among others, underlie these disorders.Hong Kong: The former British crown colony located off the southeast coast of China, comprised of Hong Kong Island, Kowloon Peninsula, and New Territories. The three sites were ceded to the British by the Chinese respectively in 1841, 1860, and 1898. Hong Kong reverted to China in July 1997. The name represents the Cantonese pronunciation of the Chinese xianggang, fragrant port, from xiang, perfume and gang, port or harbor, with reference to its currents sweetened by fresh water from a river west of it.Receptors, Androgen: 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.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.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Hypogonadism: Condition resulting from deficient gonadal functions, such as GAMETOGENESIS and the production of GONADAL STEROID HORMONES. It is characterized by delay in GROWTH, germ cell maturation, and development of secondary sex characteristics. Hypogonadism can be due to a deficiency of GONADOTROPINS (hypogonadotropic hypogonadism) or due to primary gonadal failure (hypergonadotropic hypogonadism).Gonadotropin-Releasing Hormone: A decapeptide that stimulates the synthesis and secretion of both pituitary gonadotropins, LUTEINIZING HORMONE and FOLLICLE STIMULATING HORMONE. GnRH is produced by neurons in the septum PREOPTIC AREA of the HYPOTHALAMUS and released into the pituitary portal blood, leading to stimulation of GONADOTROPHS in the ANTERIOR PITUITARY GLAND.Kallmann Syndrome: A genetically heterogeneous disorder caused by hypothalamic GNRH deficiency and OLFACTORY NERVE defects. It is characterized by congenital HYPOGONADOTROPIC HYPOGONADISM and ANOSMIA, possibly with additional midline defects. It can be transmitted as an X-linked (GENETIC DISEASES, X-LINKED), an autosomal dominant, or an autosomal recessive trait.Gonadotrophs: Anterior pituitary cells that can produce both FOLLICLE STIMULATING HORMONE and LUTEINIZING HORMONE.Reproduction: The total process by which organisms produce offspring. (Stedman, 25th ed)Receptors, LHRH: Receptors with a 6-kDa protein on the surfaces of cells that secrete LUTEINIZING HORMONE or FOLLICLE STIMULATING HORMONE, usually in the adenohypophysis. LUTEINIZING HORMONE-RELEASING HORMONE binds to these receptors, is endocytosed with the receptor and, in the cell, triggers the release of LUTEINIZING HORMONE or FOLLICLE STIMULATING HORMONE by the cell. These receptors are also found in rat gonads. INHIBINS prevent the binding of GnRH to its receptors.Gonadotropins: Hormones that stimulate gonadal functions such as GAMETOGENESIS and sex steroid hormone production in the OVARY and the TESTIS. Major gonadotropins are glycoproteins produced primarily by the adenohypophysis (GONADOTROPINS, PITUITARY) and the placenta (CHORIONIC GONADOTROPIN). In some species, pituitary PROLACTIN and PLACENTAL LACTOGEN exert some luteotropic activities.Infertility, Female: Diminished or absent ability of a female to achieve conception.Gonadal Disorders: Pathological processes of the OVARIES or the TESTES.Methyltestosterone: A synthetic hormone used for androgen replacement therapy and as an hormonal antineoplastic agent (ANTINEOPLASTIC AGENTS, HORMONAL).Puberty: A period in the human life in which the development of the hypothalamic-pituitary-gonadal system takes place and reaches full maturity. The onset of synchronized endocrine events in puberty lead to the capacity for reproduction (FERTILITY), development of secondary SEX CHARACTERISTICS, and other changes seen in ADOLESCENT DEVELOPMENT.Infertility: Inability to reproduce after a specified period of unprotected intercourse. Reproductive sterility is permanent infertility.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.Androgens: 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.Surgically-Created Structures: Organs or parts of organs surgically formed from nearby tissue to function as substitutes for diseased or surgically removed tissue.Credentialing: The recognition of professional or technical competence through registration, certification, licensure, admission to association membership, the award of a diploma or degree, etc.Certification: Compliance with a set of standards defined by non-governmental organizations. Certification is applied for by individuals on a voluntary basis and represents a professional status when achieved, e.g., certification for a medical specialty.Public Health: Branch of medicine concerned with the prevention and control of disease and disability, and the promotion of physical and mental health of the population on the international, national, state, or municipal level.Public Health Nursing: A nursing specialty concerned with promoting and protecting the health of populations, using knowledge from nursing, social, and public health sciences to develop local, regional, state, and national health policy and research. It is population-focused and community-oriented, aimed at health promotion and disease prevention through educational, diagnostic, and preventive programs.Registries: The systems and processes involved in the establishment, support, management, and operation of registers, e.g., disease registers.Medical Staff Privileges: Those rights or activities which are specific to members of the institution's medical staff, including the right to admit private patients.Genetic Testing: Detection of a MUTATION; GENOTYPE; KARYOTYPE; or specific ALLELES associated with genetic traits, heritable diseases, or predisposition to a disease, or that may lead to the disease in descendants. It includes prenatal genetic testing.Education, Graduate: Studies beyond the bachelor's degree at an institution having graduate programs for the purpose of preparing for entrance into a specific field, and obtaining a higher degree.Faculty: The teaching staff and members of the administrative staff having academic rank in an educational institution.Students: Individuals enrolled in a school or formal educational program.Education, Pharmacy, Graduate: Educational programs for pharmacists who have a bachelor's degree or a Doctor of Pharmacy degree entering a specific field of pharmacy.

Quite often those decisions are surgical and often irreversible. Former patients and health care advocates have long complained that parents are provided inadequate information to make decisions for their child with a disorder of sex development.. But with a new award from the Patient-Centered Outcomes Research Institute (PCORI), researchers at the University of Michigan hope to provide parents with the tools needed to make decisions about disorders of sex development (DSD).. "When a child with a disorder of sex development is born, parents are often experiencing enormous distress," says David E. Sandberg, Ph.D., director of the Division of Child Behavioral Health at C.S. Mott Childrens Hospital and professor of pediatrics and communicable diseases at the University of Michigan Medical School.. "The right decisions about gender assignment - is it a boy or a girl - and the best course of action (for example should there be surgery? what kind? when?) are not obvious.". "Parents can make decisions ...
Genetic testing for up to 15 genes that are associated with non-syndromic male sex reversal or ambiguous genitalia caused by 46,XY disorder of sex development (DSD) or 46,XY complete gonadal dysgenesis (CGD).
Disorders of sex development (DSD), sometimes referred to as disorders of sex differentiation or differences of sex development, are medical conditions involving the reproductive system. More specifically, these terms refer to "congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical." The term has been controversial, and research has shown that affected people experience a negative impact, with the terminology impacting choice and utilization of health care providers. The World Health Organization and many medical journals still reference DSDs as intersex traits or conditions. The Council of Europe, and Inter-American Commission on Human Rights have called for a review of medical classifications that unnecessarily medicalize intersex traits. DSDs are medical conditions involving the way the reproductive system develops from infancy (and before birth) through young adulthood. There are several types of DSDs and their effect on the external and internal ...
Abstract: Disorders of sex development (DSD) is an umbrella term for congenital conditions in which anatomic, gonadal, or chromosomal sex is atypical. DSD is found in 7.5% of all births defects and 1 in 5,000 babies born worldwide have significant ambiguous genitalia. Best practices involve multidisciplinary teams, informed consent and shared decision-making with the patient and family. As a group, DSD patients are rare and therefore clinically challenging. Primary care providers, family medicine physicians, and pediatricians are the foundation for patients medical care and therefore play a key role in the initial diagnosis, guidance, coordination of care, and long-term management ...
In the community of sex and gender minorities, some (but not all) people have differences of sex development. These traits can include medically detectable physiological differences in chromosomes, gonads, sex hormones, or genitals.. These differences are not always visible, and some people with differences of sex development do not know they have these traits until they are tested.. Some people identify as both transgender and having a difference of sex development. Others are transgender but do not have a known difference of sex development. Many people with a difference of sex development, especially those who accept their sex assigned at birth, do not consider themselves transgender.. ...
Objective: Steroid measurement is a challenge in pediatric endocrinology. Currently, liquid chromatography with tandem mass spectrometry (LC-MS/MS) is considered a gold standard for this purpose. The aim of this study was to compare both LC-MS/MS and immunoassay (IA) for androgens before and after human recombinant chorionic gonadotropin (r-hCG) stimulus in children with 46,XY Disorders of Sex Development (DSD). Methods: Nineteen patients with 46,XY DSD were evaluated; all of them were prepubertal and non gonadectomized. Testosterone, dihydrotestosterone (DHT), dehydroepiandrosterone (DHEA) and androstenedione were measured by IA and LC-MS/MS before and 7 days after rhCG injection. The correlation between IA and LC-MS/MS was analysed by the intraclass correlation coefficient (ICC) and Spearmans rank correlation coefficient (SCC). For concordance analysis the Passing and Bablok (PB) regression and the Bland and Altman (BA) method were used. Results: Testosterone showed excellent correlation (ICC ...

Disorders of sex development (DSDs) are congenital conditions resulting in atypical chromosomal, gonadal or anatomic sex. Around 80% of 46,XY DSD cases still remain unexplained genetically. Phenotypes include gonadal dysgenesis, male-to-female sex reversal and hypospadias, where the urethra is abnormally positioned along the penis. Mutations in SOX9, a gene essential for testicular development, have been implicated in DSDs, but its tissue-specific regulation is not fully understood. SOX9 tissue-specific enhancer mutations can cause isolated clinical phenotypes. Through genome wide mapping, mutations around SOX9 have been identified in isolated DSD patients. All patients had gonadal defects and hypospadias. We hypothesised that a 78 kb region encompassing these mutations contains a novel gonadal enhancer that we aimed to identify. Comparative genomic analysis identified seven highly conserved sub-regions within TES2. Unexpectedly, transgenic mouse analysis revealed that the most highly conserved ...
Australian scientists have discovered that changes to a gene involved in brain development can lead to testis formation and male genitalia in an otherwise female embryo. Lead Melbourne researcher Professor Andrew Sinclair, of the Murdoch Childrens Research Institute and the University of Melbourne, said the breakthrough would improve diagnosis and clinical management of patients with disorders of sex development (DSD). These conditions occur when the testes or ovaries do not develop properly in the embryo, causing genital abnormalities in one in 4500 babies. The gene, called SOX3, sits on the X chromosome and is normally involved in the development of the central nervous system and the brains pituitary gland. But, scientists found that mutations affecting the SOX3 gene caused it to be abnormally turned on in the embryonic gonad, leading to testis development in human DSD patients and mice.. In males, testis development is regulated by an almost identical gene on the Y chromosome known as SRY. ...

But it raised problems of informed consent, as parents made the decision on their childs behalf as to which sex they would be. What if they got it wrong and the child grew up hating who they were?. Some people have reported growing up never feeling comfortable or accepted in their gender role. There are many accounts - real life and fictional - of difficult transitions to the other sex, as in the Pulitzer-Prize winning novel Middlesex.. Now, the trend is to be supportive, conservative and avoid removing genital tissues if the condition is not life threatening.. But there are no universal answers. In a perfect world, it wouldnt matter if a child was a boy, girl or a happy intersex. But our society is sexualised and children can be cruel to those even trivially different.. Adults are sometimes no more accepting; in some Asian and African countries families with DSD children may be ostracised and children neglected or killed.. Developed countries are moving in the right direction in their ...

Background: Steroidogenic factor-1 (SF-1), denominated as nuclear receptor subfamily five group A member 1 (NR5A1), is an orphan receptor that regulates several steps of adrenal and gonadal development. Mutations in its gene are responsible for different phenotypes of disorders of sex development (DSD).. Objective and hypotheses: To study the functional impact of two novel NR5A1 mutations, the p.C247* and p.K396Rfs*34, both identified within the ligand-binding domain (LBD).. Method: In order to evaluate the impact of those mutations at the protein function, normal and mutated SF-1 were expressed in HeLa cells and the expression efficiency was monitored using Western blot. Their transactivation abilities were tested in vitro using AMH and STAR promoter containing luciferase reporter genes and electrophoretic mobility shift assays (EMSA).. Results: Luciferase reporter gene expression was reduced for both p.C247* and p.K396Rfs*34 when tested with either promoters. Whereas the transactivation ...
Some labs are as white and sterile as hospital rooms, but Karyn Fricks looks more like the inside of FAO Schwarz. Everywhere you look, there are buckets crammed with plastic toys in rainbow colors, transforming the lab into one big amusement park for the dozens of female mice in residence. But Fricks not out just to keep her rodent charges occupied; she uses the toys to glean insight into how they learn and remember. She picks up two identical multicolored prisms and puts them in a large white box, a kind of murine playpen. "We put two of these objects in," she explains, "and let the mice explore for 30 seconds." Next comes the crucial step: injecting the mice with estrogen.. Scientists have long known that estrogen is responsible for female sex development in mammals. Frick, a Yale associate professor of psychology, is one of a growing number of researchers who have done experiments showing that the hormone also aids memory in females. (Estrogen is also important for males. Many of the ...

The two novel mutations p.Asp266Asn and p.Thr576Pro in the AR gene lie within the N-terminal domain of the androgen receptor that is involved in transcription regulation and DNA binding, respectively. Missense mutations around these two codons have been reported in patients with AIS according to the Androgen Receptor Gene Mutations Database, April 2013.20 Multiple sequence alignment shows that both amino acids are highly conserved among different species, suggesting that aspartic acid at codon 266 and threonine at codon 576 are critical for proper receptor function. Similarly, the alanine at codon 260 of the NR5A1 gene is located in helix 3 of the ligand-binding domain of the nuclear receptor,21 and is also a highly conserved region. Mutation in this region has been reported to result in 46,XY DSD.8 Replacing alanine at this position by valine is therefore expected to be deleterious to the protein function. Phenotypic variability in NR5A1 gene mutation within a kindred has been reported and this ...

Dr. Adibi: Prenatal exposure to phthalates in rodents can cause defects in male sexual development including a shorter distance between the anus and the genitalia (anogenital distance or AGD). Human studies have shown a correlation between higher prenatal phthalate urinary concentrations in the mother and shorter AGD in males. AGD in males is related to fertility and reproductive health over the lifetime. In females, AGD was associated with numbers of ovarian follicles. The role of the placenta has not been considered in these studies. A placental hormone called human chorionic gonadotropin (hCG) is essential for normal male development. Our previous research has shown that hCG expression by human placental cells is disrupted by phthalate concentrations equal to what we measured in maternal urine. The placenta secretes molecules early in pregnancy that might provide an opportunity to detect these effects in humans.. Medical Research: What are the main findings?. Dr. Adibi: In 350 pregnancies, we ...
Being the most common form of OT-DSD, ovotestis should be screened out during preoperative physical examination according to the typical morphological features. Internal genital ducts adjacent to the ovotestis are usually difficult to identify with naked eyes, and frozen biopsy is warranted in surgery.. On the basis of PVE classification system [16], we designed UVB measurement to assess the location of vagina confluence and the length of urogenital sinus and vagina. The critical factor in the vaginoplasty is not the length of the common sinus but rather the distance from the bladder neck to the location of vagina confluence. The former index is very useful in the surgical planning of vaginoplasty. Partial urogenital mobilization (PUM) or flap vaginoplasty is indicated based on these evaluations.. Our multidisciplinary team and the families took part in the gender assignment. Prader grading, karyotype, nature and function of gonads, values of UVB, presence of Müllerian ducts, psychological ...

For the last three days, I have been struggling with what to write regarding the Swiss Federal Tribunals (SFT) Decision to dismiss a challenge from Caster Semenya and Athletics South Africa (ASA) against the Court of Arbitration for Sports (CAS) Decision to dismiss a challenge to the Eligibility Regulations for the Female Classification (Athletes with Differences of Sex Development), otherwise known as the DSD Regulations. From reading World Athletics statement welcoming the ruling, one could be forgiven for thinking that it had won a major trial. Sports journalists, accustomed to covering events now curtailed by Covid-19, focus on the fact that Semenya has lost her case against the DSD Regulations. Neither assertion is strictly accurate.. The SFTs powers to review the CASs ruling are severely limited. It can only consider whether the CAS Decision violates widely recognised principles of public order on Swiss public policy grounds. The SFT has only reversed a decision based on a a ...

Steroidogenic acute regulatory protein (STAR) is a key protein for the intracellular transport of cholesterol to the mitochondrium in endocrine organs (e.g. adrenal gland, ovaries, testes) and essential for the synthesis of all steroid hormones. Several mutations have been described and the clinical phenotype varies strongly and may be grouped into classic lipoid congenital adrenal hyperplasia (LCAH), in which all steroidogenesis is disrupted, and non-classic LCAH, which resembles familial glucocorticoid deficiency (FGD), which affects predominantly adrenal functions. Classic LCAH is characterized by early and potentially life-threatening manifestation of primary adrenal insufficiency (PAI) with electrolyte disturbances and 46,XY disorder of sex development (DSD) in males as well as lack of pubertal development in both sexes. Non-classic LCAH manifests usually later in life with PAI. Nevertheless, life-long follow-up of gonadal function is warranted. We describe a 26-year-old female patient who ...
Smith Lemli Opitz syndrome (SLOS) is a 46,XY disorder of sex development, included in the subgroup of disorders in androgene synthesis. The disease is caused by mutations of 7-dehydrocholesterol reductase (DHCR7) gene, conducting to deficient synthesis of the correspondent enzyme and of cholesterol, with important role in embryogenesis, adrenal and gonadal steroidogenesis. Clinical manifestations includ facial dysmorphism, syndactyly, ambiguous external genitalia and visceral malformations.. We present the case of an infant born by cesarean section for fetal suffering (Apgar score 8/1′ 8/5′), with multiple malformations (dysmorphic face, polydactyly, syndactyly, hypospadias, cryptorchidism) detected already at birth. Investigations diagnosed small atrial septal defect and corpus callosum agenesis was suspected. The clinical examination at 4 months of age showed growth failure, dysmorphic face, bilateral ptosis and epicantus, generalized muscle hypotony, asymmetrical polydactyly (complete on ...
The gonads develop from the urogenital ridges (Figure 43-1), which are formed during the 4th week of gestation by the proliferation of the coelomic epithelium and condensation of the underlying mesenchyme along the mesonephros. The germ cells, located in the endoderm of the yolk sac, migrate to the genital ridges. At the early stage of development, the gonad is bipotential, capable of forming into either a testis or an ovary. During the 6th-7th week of gestation, at least four different genes, Wilms tumor suppressor gene (WT-1), Fushi-Tarza Factor-1 (FTZ-F1), steroidogenic Factor-1 (SF-1), and LIM-1, induce the development of the testis. The primordial germ cells differentiate into the Sertoli cells and associated Leydig cells, which aggregate into spermatogenic cords. Loose mesenchymal tissue condenses into a thick layer, the tunica albuginea, which surrounds the testis and separates its connection with the coelomic epithelium, thereby preventing further migration of mesonephric cells into the ...

WNT4 is a secreted protein that in humans is encoded by the Wnt4 gene, found on chromosome 1. It promotes female sex development and represses male sex development. Loss of function can have serious consequences, such as female to male sex reversal. The WNT gene family consists of structurally related genes that encode secreted signaling proteins. These proteins have been implicated in oncogenesis and in several developmental processes, including regulation of cell fate and embryogenesis. WNT4 is involved in a couple features of pregnancy as a downstream target of BMP2. For example, it regulates endometrial stromal cell proliferation, survival, and differentiation. These processes are all necessary for the development of an embryo. Ablation in female mice results in subfertility, with defects in implantation and decidualization. For instance, there is a decrease in responsiveness to progesterone signaling. Furthermore, postnatal uterine differentiation is characterized by a reduction in gland ...

My physical aesthetic and my work is always in black and white.. "I will continue to enforce these unnecessary binary limitations on my work and appearance until the UK recognises the hermaphrodite in law and adds a third box to the category of gender in passports, following in the footsteps of countries like Australia, New Zealand and India. "Evidence that the hermaphrodite exists is obviously overwhelmingly supported by science yet our society and its laws still ignore people like me.". And she is not alone in wanting change. There is a growing recognition of the inadequate and often damaging treatment given to children born with both male and female sexual organs.. The medical community has long regarded hermaphrodism as something that can be solved (Disorders of Sex Development - DSD) by corrective surgery or by picking what gender to raise a child based on the extent of their physical development. This is usually decided not long after birth and within the first 18 months of a childs ...
Information about disorders relating to sex development, meaning the biological physical features of a persons sex. Such disorders can be genetic; and can first manifest themselves in the womb with the prenatal development of the internal sex organs (including the gonads) and the external sex organs (like the penis, clitoris, labia, and scrotum); or at puberty.
A molecular biologist, John Loke investigates the genetic basis for disorders of sex development and cancer. He dissected the findings of genetic discoveries into intricate pathways and is currently studying in great detail the MAP kinase pathway in gonadal development by flow cytometry proteomics and next generation parallel sequencing. His recent publication in the American Journal of Human Genetics (2010 Dec 10; 87(6):898-904) on the role of MAP3K1 as "Genetic Switch" in human sex divergence during development, was widely received by the media and the scientific community. He is also working closely with Drs. Ostrer and Pearlman to further the development of the metastatic signature for prostate and breast cancer predictions so it can be used to identify peoples risks for having a disease, or its outcome once it has occurred.
