'''XX gonadal dysgenesis''' is a type of female [[hypogonadism]] in which the ovaries do not function to induce [[puberty]] in an otherwise normal girl whose [[karyotype]] is found to be 46,XX. With nonfunctional [[streak ovaries]], she is low in [[estrogen]] levels ([[Hypoestrogenism|hypoestrogenic]]) and has high levels of [[Follicle-stimulating hormone|FSH]] and [[Luteinizing hormone|LH]]. Estrogen and [[progesterone]] therapy is usually then commenced. Some cases are considered a severe version of [[premature ovarian failure]] where the ovaries fail before puberty.<ref>{{cite journal |last1=Ledig |first1=S |last2=Röpke |first2=A |last3=Wieacker |first3=P |title=Copy number variants in premature ovarian failure and ovarian dysgenesis. |journal=Sexual Development |date=September 2010 |volume=4 |issue=4–5 |pages=225–32 |doi=10.1159/000314958 |pmid=20606390|s2cid=20694337 }}</ref>

Some forms of XX gonadal dysgenesis occurs with [[sensorineural deafness]]. This type is also known as '''Perrault syndrome''', an [[autosome|autosomal]] recessive disease affecting both sexes.

'''Signs and Symptoms'''


Individuals with XX gonadal dysgenesis appear phenotypical female with normal internal and external genitalia, bilateral streak gonads, and normal stature. Diagnosis commonly occurs in adolescence due to delayed puberty or amenorrhea. Some individuals may have some breast development, secondary amenorrhea, or ovarian follicles on imaging rather than the expected streak or hypoplastic ovaries.<ref>{{Cite book |last=Lobo |first=Roger |title=Comprehensive Gynecology |publisher=Elsevier |year=2022 |isbn=978-0-323-65399-2 |edition=8th |location=Philadelphia, PA |pages=781-800 |chapter=Primary and secondary amenorrhea and precocious puberty}}</ref>
The term "pure gonadal dysgenesis" (PGD) has been used to distinguish a group of patients from gonadal dysgenesis related to [[Turner syndrome]]. In the latter a distinct chromosomal aberration is present, while in PGD the chromosomal constellation is either 46,XX or 46,XY. Thus XX gonadal dysgenesis is also referred to as ''PGD, 46 XX'', and XY gonadal dysgenesis as ''PGD, 46,XY'' or [[Swyer syndrome]].<ref>[http://www.medscape.com/viewarticle/499501_5 Log In Problems<!-- Bot generated title -->]</ref> Patients with PGD have a normal chromosomal constellation but may have localized genetic alterations.

There have been some cases with other associated features such as sensorineural hearing loss (i.e., Perrault Syndrome), neurologic abnormalities, renal disease, malformation syndromes, clitoromegaly, or cerebellar ataxia.<ref name=":12">{{Cite book |last=Thompson |first=Shelby |title=Fanaroff and Martin's Neonatal-Perinatal Medicine |last2=Wherrett |first2=Diane |publisher=Elsevier |year=2025 |isbn=978-0-323-93266-0 |edition=12th |location=Philadelphia, PA |pages=1750-1789 |chapter=Disorders of Sex Development}}</ref><ref>{{Citation |last=Simpson |first=Joe Leigh |title=Germ Cell Failure and Ovarian Resistance: Human Genes and Disorders |date=2004 |work=The Ovary |pages=541–557 |url=https://linkinghub.elsevier.com/retrieve/pii/B9780124445628500331 |access-date=2024-12-01 |publisher=Elsevier |language=en |doi=10.1016/b978-012444562-8/50033-1 |isbn=978-0-12-444562-8 |last2=Rajkovic |first2=Aleksandar}}</ref>

The term "pure gonadal dysgenesis" (PGD) has been used to differentiate between gonadal dysgenesis related to [[Turner syndrome]]. Turner syndrome occurs due to partial or complete absence of one of the X chromosomes, resulting in 45,XO or 45,X. Associated characteristics include short stature, a broad shield-like chest, webbed neck, premature ovarian failure, and heart and kidney abnormalities to name a few.<ref>{{Cite book |last=Kikkeri |first=Shankar |title=StatPearls |last2=Nagalli |first2=Shivaraj |date=Aug 8, 2023 |publisher=Treasure Island |location=Florida |chapter=Turner Syndrome}}</ref> People with XX gonadal dysgenesis do not generally have the characteristics listed before, other than the primary ovarian insufficiency.<ref name=":3">{{Cite book |last=Smith |first=Roger |title=Netter's Obstetrics and Gynecology |publisher=Elsevier |year=2024 |isbn=978-0-44310739-9 |edition=4th |location=Philadelphia, PA |pages=428-430 |chapter=Gonadal Dysgenesis}}</ref>
XX gonadal dysgenesis is related to the [[Swyer syndrome]] in as much as both conditions have the same phenotype and clinical issues; however in Swyer syndrome the karyotype is 46,XY, and thus gonadectomy is recommended.<ref>{{cite journal |author=Sebastiano Campo |title=Laparoscopic gonadectomy in two patients with gonadal dysgenesis |journal=The Journal of the American Association of Gynecologic Laparoscopists |year=1998}}</ref>


Meanwhile in PGD the chromosomal constellation is either 46,XX or 46,XY.Thus XX gonadal dysgenesis is also referred to as ''PGD, 46 XX''. Meanwhile, XY gonadal dysgenesis is known as ''PGD, 46,XY'' or [[Swyer syndrome]]. Patients with PGD have a normal chromosomal constellation but may have localized genetic alterations. XX gonadal dysgenesis is related to [[Swyer syndrome]] in as much as both conditions have the same phenotype and clinical issues; however in Swyer syndrome the karyotype is 46,XY. Gonadectomy is recommended in these individuals due to the risk of malignant tumors due to mosaicism in the Y chromosome.<ref name=":22">{{Cite book |last=Netter |first=Frank |title=Netter Collection of Medical Illustrations: Reprodctive System |publisher=Elsevier |year=2025 |isbn=978-0-323-88083-1 |edition=3rd |location=Philadelphia, PA |pages=197-226 |chapter=Ovaries}}</ref>
In [[Turner syndrome]] there is a demonstrable abnormality in or absence of one of the sex chromosomes that is the cause of the development of gonadal dysgenesis. In contrast XX gonadal dysgenesis has a normal female chromosome situation.{{citation needed|date=September 2021}}


Gonadal dygenesis has also been related to other syndromes such as [[WAGR syndrome|WAGR syndome]], [[Denys–Drash syndrome|Denys-Drash Syndrome]], and [[Malouf syndrome]].<ref name=":02">{{Citation |last=Stafford |first=Diane E.

== Pathogenesis ==
== Pathogenesis ==
XX gonadal dysgenesis is thought to be mainly caused by genetic defects in the pathways of ovarian development, specifically via autosomal-recessive inheritance since a positive family history or consanguinity has been noted. However, sporadic cases also have been reported. Ongoing research has identified some implicated genes, listed below, which often are in pathways of gonadal differentiation and formation as well as germ cell migration.<ref name=":14">{{Cite book |last=Thompson |first=Shelby |title=Fanaroff and Martin's Neonatal-Perinatal Medicine |last2=Wherrett |first2=Diane |publisher=Elsevier |year=2025 |isbn=978-0-323-93266-0 |edition=12th |location=Philadelphia, PA |pages=1750-1789 |chapter=Disorders of Sex Development}}</ref><ref>{{Cite journal |last=Laissue |first=Paul |date=2015-08-15 |title=Aetiological coding sequence variants in non-syndromic premature ovarian failure: From genetic linkage analysis to next generation sequencing |url=https://www.sciencedirect.com/science/article/pii/S0303720715002397?via=ihub |journal=Molecular and Cellular Endocrinology |volume=411 |pages=243–257 |doi=10.1016/j.mce.2015.05.005 |issn=0303-7207}}</ref><ref name="Witchel">{{cite book |last1=Witchel |first1=Selma Feldman |title=Pediatric Endocrinology |last2=Lee |first2=Peter A. |date=2014 |isbn=9781455748587 |pages=107–156.e1 |chapter=Ambiguous genitalia |doi=10.1016/B978-1-4557-4858-7.00014-7}}</ref>

Evaluation of [[delayed puberty]] usually reveals the presence of pubic hair, but elevation of [[gonadotropin]]s, indicating that the pituitary is providing the signal for puberty but the gonads are failing to respond. The next steps of the evaluation usually include checking a [[karyotype]] and imaging of the pelvis. The karyotype reveals XX chromosomes and the imaging demonstrates the presence of a uterus but no ovaries (the streak gonads are not usually seen by most imaging). At this point it is usually possible for a physician to make a diagnosis of XX gonadal dysgenesis.{{citation needed|date=September 2021}}

XX gonadal dysgenesis
Other namesXX ovarian dysgenesis, Perrault syndrome
SpecialtyMedical genetics Edit this on Wikidata

XX gonadal dysgenesis is a type of female hypogonadism in which the ovaries do not function to induce puberty in a person assigned female at birth, whose karyotype is 46,XX.[1] Individuals with XX gonadal dysgenesis have normal-appearing external genitalia as well as Müllerian structures (e.g., cervix, vagina, uterus). Due to the nearly absent or nonfunctional streak ovaries, the individual is low in estrogen levels (hypoestrogenic) and has high levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), hormones that cycle in the reproductive system.[2] As a result, the diagnosis often occurs after a concern for delayed puberty or amenorrhea. Treatment generally involves hormone replacement therapy with estrogen and progesterone.[3]

Presentation

Signs and Symptoms

Individuals with XX gonadal dysgenesis appear phenotypical female with normal internal and external genitalia, bilateral streak gonads, and normal stature. Diagnosis commonly occurs in adolescence due to delayed puberty or amenorrhea. Some individuals may have some breast development, secondary amenorrhea, or ovarian follicles on imaging rather than the expected streak or hypoplastic ovaries.[4]

There have been some cases with other associated features such as sensorineural hearing loss (i.e., Perrault Syndrome), neurologic abnormalities, renal disease, malformation syndromes, clitoromegaly, or cerebellar ataxia.[5][6]

The term "pure gonadal dysgenesis" (PGD) has been used to differentiate between gonadal dysgenesis related to Turner syndrome. Turner syndrome occurs due to partial or complete absence of one of the X chromosomes, resulting in 45,XO or 45,X. Associated characteristics include short stature, a broad shield-like chest, webbed neck, premature ovarian failure, and heart and kidney abnormalities to name a few.[7] People with XX gonadal dysgenesis do not generally have the characteristics listed before, other than the primary ovarian insufficiency.[8]

Meanwhile in PGD the chromosomal constellation is either 46,XX or 46,XY.Thus XX gonadal dysgenesis is also referred to as PGD, 46 XX. Meanwhile, XY gonadal dysgenesis is known as PGD, 46,XY or Swyer syndrome. Patients with PGD have a normal chromosomal constellation but may have localized genetic alterations. XX gonadal dysgenesis is related to Swyer syndrome in as much as both conditions have the same phenotype and clinical issues; however in Swyer syndrome the karyotype is 46,XY. Gonadectomy is recommended in these individuals due to the risk of malignant tumors due to mosaicism in the Y chromosome.[9]

Gonadal dygenesis has also been related to other syndromes such as WAGR syndome, Denys-Drash Syndrome, and Malouf syndrome.[10][11]

Pathogenesis

XX gonadal dysgenesis is thought to be mainly caused by genetic defects in the pathways of ovarian development, specifically via autosomal-recessive inheritance since a positive family history or consanguinity has been noted. However, sporadic cases also have been reported. Ongoing research has identified some implicated genes, listed below, which often are in pathways of gonadal differentiation and formation as well as germ cell migration.[12][13][14]

In cases with hearing involvement (Perrault syndrome), the following genes are implicated:[22]

Diagnosis

Because of the inability of the streak gonads to produce sex hormones (both estrogens and androgens), most of the secondary sex characteristics do not develop. This is especially true of estrogenic changes such as breast development, widening of the pelvis and hips, and menstrual periods. Because the adrenal glands can make limited amounts of androgens and are not affected by this syndrome, most of these individuals will develop pubic hair, though it often remains sparse.[30]

Diagnosis usually occurs after evaluation for a concern of delayed puberty. Next steps involve laboratory studies, such as FSH and LH levels. Other laboratory studies such as testosterone, dehydroepiandrosterone, anti-Mullerian hormone, human chorionic gonadotropin, thyroid-stimulating hormone, and prolactin are apart of some algorithms to investigate primary amenorrhea.[31][32] Imaging can include a pelvic ultrasound or MRI, which would reveal normal internal genitalia such as a uterus but with streak gonads, which can be small and not easily visualized.[33][34] Genetic testing involves chromosomal analysis via karyotype to confirm XX chromosomes, rather than XO or XY as discussed in related syndromes above.[35][36]

Treatment

Treatment involves hormone replacement therapy that mirrors physiologic levels that would be otherwise provided by functional ovaries. Induction of puberty and menstruation relies on estrogen, which can be given in oral or transdermal forms. Estrogen also has protective effects against osteopenia/osteoporosis as well as cardiovascular health and urogenital atrophy later in life.[37] Progesterone therapy is added after 12 months of estrogen or after menstruation has begun, whichever comes first, which decreases the risk of endometrial hyperplasia and subsequent cancer.[38] Combined oral contraceptives can also be used.[39]

In terms of fertility, pregnancy could be facilitated through egg donation and in vitro fertilization, as individuals with XX gonadal dysgenesis still have a functional uterus.[40]

Prognosis

Prognosis is dependent on whether these individuals have any comorbidities or if the gonadal dysgenesis is apart of a syndrome. Without other somatic stigmata, complications include effects on fertility and other comorbidities generally associated with primary ovarian insufficiency such as bone health, cardiovascular risks, and psychosocial stressors.[41]

History

In 1951, Perrault, Klotz, and Housset reported the association of gonadal dysgenesis and deafness in two sisters, and this presentation is now called Perrault syndrome. [already has citation]. The first described case of pure gonadal dysgenesis was in 1960, in a patient with presumed Turner syndrome but without the expected stigmata.[42]
