Intersex: True hermaphrodite has both testicular tissue &amp; ovarian gonadal tissue. causes of pseudohermaphroditism. The two primary causes of male pseudohermaphroditism are androgen insensitivity syndrome and 5-alpha reductase deficiency. Biochemical and histologic evi-dence for such diagnosis is presented. Most cases are secondary to 21-hydroxylase deficiency. Pseudohermaphroditism or pseudo-hermaphroditism, is a name used to describe the fact that some people are born with external sex organs that look intermediate between the typical vagina or penis. Male Pseudohermaphroditism Pseudohermaphroditism, or pseudo-herrna-phroditism, is the condition in which an organism is born with secondary, sex characteristics or a phenotype that is different from what would be expected on the basis of the gonadal tissue (ovary or testis). Examples are individuals with congenital adrenal hyperplasia (CAH), also known as adrenogenital syndrome ( Figure 5.9 ). The cause is a congenital suprarenal hyperplasia (recessive autosomal illness), a maternal . This results in failure of full masculinization of the male genitalia. Main cause of female pseudohermaphroditism: Congenital virilizing adrenal hyperplasia. Nomenclature and Classification A new nomenclature for disorders of sexual differentiation has been proposed by the In-ternational Consensus Conference on Intersex Female pseudohermaphroditism associated with luteoma of pregnancy (LP) is a rare condition characterized by varying degrees of masculinization of a female fetus. Three patients are described with 46XX genotype, pseudohermaphroditism, a cloaca, and preserved renal function, suggestive of a syndrome where embryogenesis is independent of hormonal status. Causes androgen insensitivity syndrome Leydig cell failure testosterone synthesis defects 5-alpha reductase deficiency In a baby with ambiguous genitalia, the genitals may be incompletely developed or the baby may have characteristics of both sexes. Specializes in Pediatric Urology. The causes of female pseudohermaphroditism (46,XX DSD) include CAH and transplacental androgen exposure. The increasing number of reports of this constellation of abnormalities is suggestive of a syndrome where embryogenesis is independent of hormonal status. On the other hand, by means of a hormonal . There are several possible causes: Congenital adrenal hyperplasia (the most common cause). This condition used to be called "male pseudohermaphroditism". pseudohermaphrodite. Pseudohermaphroditism is a condition in which an individual has a matching chromosomal and gonadal tissue (ovary or testis) sex, but mismatching external genitalia.. Maternal androgen excess due to maternal ovarian tumor or drug intake also causes female pseudohermaphroditism. The causes of this can be male hormones taken during pregnancy, congenital adrenal hyperplasia, male-hormone-producing tumors in the mother and aromatase deficiency. The term CAH encompasses a group of autosomal recessive disorders, each of which involves a deficiency of an enzyme involved in the synthesis of cortisol, aldosterone, or both. Milder forms of male pseudohermaphroditism include Klinefelter syndrome (47,XXY; 48,XXXY and mosaics), Kallmann syndrome (gonadotropin-releasing hormone deficiency and anosmia), micropenis, and distal hypospadias. that cause ambigu- ous genitalia.

Hermaphroditism in Greek means bipolarity. There are a number of causes of female pseudohermaphroditism: Congenital adrenal hyperplasia (CAH): Is caused by a defect in an enzyme (21-hydroxylase) in the steroid hormone synthesis pathway in the adrenal gland. Congenital adrenal hyperplasia, also known as adrenogenital syndrome, is a common cause of female pseudohermaphroditism. Causes. CAH is the most common cause of female pseudohermaphroditism and virilization, and decreased cortisol synthesis owing to reduction or loss of 21-hydroxylase enzyme function is the most common biochemical cause of CAH. Male pseudohermaphrodites are persons with a Y-chromosome whose external genitalia fail to develop as expected for normal males. 46, XY intersex. The final diagnosis of causes of genital ambiguity in these patients were: female pseudohermaphroditism (N=42) that included congenital adrenal hyperplasia (CAH)-35 and non-adrenal cause (maternal androgens) - 1 a; Male pseudohermaphroditism (N=24) and . Pseudohermaphroditism is a condition in which an infant is born with one chromosomal and gonadal sex, but has or develops some of the secondary sexual characteristics of the other sex.

S ex steroids of gonadal and adrenal origin have a critical role in sexual development during the different stages of life from early embryonic development to adulthood. Genetic defects that impair androgen synthesis or action will result in abnormalities of male phenotypic development in 46, XY individuals with testes (male pseudohermaphroditism). these variations they can affect chromosomes, hormones, genitals and / or secondary sex traits, Such as the distribution of muscle and fat. Is the most common cause of ambiguous genitalia in newborns. Mothers who have children with . Compare hermaphroditism.
