46, XY Disorders of Sex Development
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
Sex Reassignment Procedures
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.
46, XX Testicular Disorders of Sex Development
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.
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 Chromosome Disorders of Sex Development
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.
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.
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.
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).
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.
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.
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.
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.
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.
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.

U-M to develop guide for parents of children with disorders of sex development - Healthcanal.com : Healthcanal.com
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 ...

Disorders of sex development - Wikipedia
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 ...
Clinical Management of Disorders of Sex Development | healthPlexus.net
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 ...
Intersex resources - Transgender Map
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 ...

Oral Presentation - ASN Events
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 ...
Brain gene makes a female develop as a male
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. ...

Boy, Girl or …? Dilemmas When Sex Development Goes Awry
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 ...

Mutations at the SF-1 Ligand-Binding Domain Can Lead to Different Effects on DNA Binding: Report of Two Novel Mutations |...
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 ...
Request for feedback: Proposed policy for gonadal & genital surgery for infants and children with DSD | Living with CAH
NHS England has proposed a new policy around gonadal and genital surgery in infants and children with DSD (difference in sex development). A key part of the proposed policy is that surgery will not be available as a routine treatment option…. until the individual concerned is able to give fully informed consent unless there is requirement for emergency surgery or for gonadal surgery when there is a clinically confirmed significant cancer risk.. As youre no doubt aware, CAH is one of the most common DSD conditions and therefore this new policy (preventing any surgery in childhood) will affect more people with CAH than those with any other DSD condition.. The Group feels that it is vital that as much feedback as possible is shared with NHS England about this proposed policy, so details about how to do this are below.. If youre a member of the support group and have agreed to receive emails from us, you will have all the details to feed back to NHS England about this policy. If youre ...

The chemical secrets of memory | Features | Yale Alumni Magazine
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 ...

Aetiological bases of 46,XY disorders of sex development in the Hong Kong Chinese population | HKMJ
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 ...

October 2016 - Great Wall China Adoption
Eva was special in that she was born with a difference of sex development. In international adoption lists, these children often have very stigmatizing language attached to their descriptions and files. For this reason, they sometimes have a harder time being adopted. A difference of sex development, or DSD, can also be called intersex. This is where someones biological development doesnt match what someone would usually expect for a girl or a boy. Many times in our society, if someone hears the word sex, things suddenly become taboo, and maybe awkward. In reality, the reproductive system has as many variations as there are for hair color or eye color. Its just another way to be human. Most people have never even heard of it. That amazes me, because I was one of those people who had never heard of it, and its as common as being born with red hair!. DSD is an umbrella term for a set of conditions that can range from something like difficulty with fertility to something more complex, like ...
MedicalResearch.com | Can Phthalates Alter Sex Development During Pregnancy?
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 ...
Evaluation and treatment for ovotesticular disorder of sex development (OT-DSD) - experience based on a Chinese series | BMC...
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 , 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 ...

Intersex can be defined as one who is born with genitalia and/or secondary sex characteristics determined as neither exclusively male nor female, or which combine features of the male and female sexes. Lately there has been a move to drop the term intersex in medical usage, replacing it with Disorders of Sex Development (DSD) in order to avoid conflating anatomy with identity. However, this has been met with criticism from some activists who consider intersex to be a third sex. The phrase ambiguous genitalia refers specifically to genital appearance, but not all intersex conditions result in atypical genital appearance ...

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 ...
A case of confirmed Smith-Lemli-Opitz syndrome | ECE2013
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 International Disorders of Sex Development (I-DSD) and International Congenital Adrenal Hyperplasia registry (I-CAH) Registries were originally developed over 10 years ago and have since supported several strands of research and led to approximately 20 peer-reviewed publications. In addition to acting as an indispensable tool for monitoring clinical and patient-centered outcomes for improving clinical practice, the registries can support a wide nature of primary and secondary research and can also act as a platform for pharmacovigilance, given their ability to collect real world patient data within a secure, ethics approved virtual research environment. The challenge for the future is to ensure that the research community continues to use the registries to improve our understanding of Disorders of Sex Development (DSD).
Chapter 43. Disorders of Sex Development | Smith & Tanaghos General Urology, 18e | AccessMedicine | McGraw-Hill Medical
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 - Wikipedia
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 ...
Disorders of sexual development may be more common in newborns than previously thought - YubaNet
Our research found 18 babies with ambiguous genitalia among 14,177 newborns (1.3 in 1,000 births). This frequency is higher when compared to previous studies (1 in 4,500-5,500), said the studys first author, Banu Kucukemre Aydin, M.D., of Istanbul University in Turkey. Many previous studies used registries with a low capture rate, but our study was done prospectively. Also, most of the published data is coming from Western countries in which consanguinity rates are lower than our country.. In the prospective study, researchers examined 14,177 newborns and found 18 of them had ambiguous genitalia. Fifteen newborns were diagnosed with 46,XY DSD, which occurs in male infants when the body cant use testosterone properly or the testicles do not develop properly. Birth weight was lower in babies with 46, XY DSD than healthy babies, and preeclampsia was a common condition in those pregnancies.. These findings support the hypothesis that early placental dysfunction and androgen deficiency might be ...

The Forgotten Sex: Hermaphrodites in Britain Fight for Official Recognition
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 ...
