Nietypowe genitalia
Objawy

Nietypowe genitalia, klasyfikowane jako zaburzenia rozwoju płci (DSD), charakteryzują się niejednoznacznym fenotypem zewnętrznych narządów płciowych noworodka, często niezgodnym z płcią genetyczną (XX lub XY). Najczęstszą przyczyną u płodów XX jest wrodzony przerost nadnerczy (CAH) z podwyższonym poziomem androgenów, co prowadzi do wirylizacji zewnętrznych narządów płciowych. U płodów XY przyczynami są m.in. zespół niewrażliwości na androgeny (AIS), niedobór 5-alfa reduktazy oraz dysgenezja jąder, skutkujące niedostateczną maskulinizacją. Fenotyp może obejmować powiększoną łechtaczkę, zrośnięte wargi sromowe lub mały penis (<2-3 cm), spodziectwo, niezstąpione jądra oraz zmienną lokalizację ujścia cewki moczowej. Diagnostyka obejmuje badania hormonalne, cytogenetyczne, obrazowe oraz biopsję tkanki gonadalnej, a w CAH potwierdzeniem jest podwyższony poziom 17-hydroksyprogesteronu (17-OHP). Epidemiologicznie częstość występowania wynosi około 1:4500 żywych urodzeń.

Definicja nietypowych genitaliów

Nietypowe genitalia (znane wcześniej jako niejednoznaczne genitalia lub ambiguous genitalia) to rzadki stan, w którym zewnętrzne narządy płciowe noworodka nie wyglądają jednoznacznie męsko lub żeńsko. Jest to jeden z rodzajów zaburzeń rozwoju płci (DSDdifferences of sex development). W przypadku dzieci z nietypowymi genitaliami, narządy płciowe mogą być niedostatecznie rozwinięte, mieć cechy obu płci lub wyglądać nietypowo w stosunku do wewnętrznych narządów płciowych czy genetycznej płci dziecka (zazwyczaj XX lub XY)123.

Nietypowe genitalia nie są chorobą, lecz różnicą w rozwoju płciowym. Stan ten jest zazwyczaj zauważalny przy urodzeniu lub krótko po nim. Według danych epidemiologicznych, częstość występowania tego zaburzenia szacuje się na około 1 na 4500 żywych urodzeń45. Wygląd zewnętrznych narządów płciowych może się znacznie różnić, a ciężkość objawów zależy od momentu, w którym podczas rozwoju płciowego doszło do zaburzeń hormonalnych oraz od przyczyny tego stanu6.

Przyczyny występowania nietypowych genitaliów

Nietypowe genitalia zazwyczaj występują, gdy zmiany hormonalne podczas ciąży zatrzymują lub zakłócają rozwój narządów płciowych nienarodzonego dziecka. Zmiana w procesach wpływających na rozwój płciowy płodu może prowadzić do niezgodności między wyglądem zewnętrznych narządów płciowych dziecka a jego wewnętrznymi narządami płciowymi lub płcią genetyczną (typowo XX lub XY)7.

Przyczyny u dzieci genetycznie żeńskich

U genetycznie żeńskich płodów (XX), nadmiar androgenów prowadzi do niejednoznacznych narządów płciowych. Główne przyczyny to:

  • Wrodzony przerost nadnerczy (CAH) – najczęstsza przyczyna nietypowych genitaliów u noworodków płci żeńskiej. W niektórych formach tego genetycznego stanu, nadnercza wytwarzają zbyt dużo hormonów zwanych androgenami89.
  • Ekspozycja na androgeny podczas rozwoju płodowego z przyczyn zewnętrznych (np. przez leki przyjmowane przez matkę)10.
  • Guzy wytwarzające androgeny u matki11.

Przyczyny u dzieci genetycznie męskich

U genetycznie męskich płodów (XY), przyczyną mogą być:

  • Problemy z rozwojem jąder, które mogą wynikać ze zmian genetycznych12.
  • Brak wytwarzania hormonów androgenowych lub ich niewystarczająca ilość13.
  • Zespół niewrażliwości na androgeny (AIS) – tkanki płodowe nie reagują prawidłowo na męskie hormony14.
  • Niedobór 5-alfa reduktazy – brak enzymu potrzebnego do przekształcenia testosteronu w dihydrotestosteron (DHT), niezbędnego do pełnej maskulinizacji płodu płci męskiej15.

W niektórych przypadkach nie udaje się zidentyfikować konkretnej przyczyny nietypowych genitaliów16.

Objawy nietypowych genitaliów

Najbardziej oczywistym objawem nietypowych genitaliów jest obecność narządów płciowych, które nie wyglądają jak typowy penis lub pochwa17. Wygląd może się znacznie różnić w zależności od czynników, które wpłynęły na rozwój narządów płciowych płodu.

Objawy u dzieci genetycznie żeńskich (XX)

U dzieci z chromosomami XX mogą występować następujące cechy:

  • Powiększona łechtaczka, która może przypominać mały penis18.
  • Otwór cewki moczowej (miejsce, z którego wypływa mocz) może znajdować się w dowolnym miejscu wzdłuż, nad lub pod powierzchnią łechtaczki19.
  • Wargi sromowe mogą być zrośnięte i przypominać mosznę20.
  • Noworodek może być uznany za chłopca z niezstąpionymi jądrami21.
  • Czasami w obrębie zrośniętych warg sromowych można wyczuć grudki tkanki, co dodatkowo upodabnia je do moszny z jądrami22.

Objawy u dzieci genetycznie męskich (XY)

U dzieci z chromosomami XY mogą występować następujące cechy:

  • Mały penis (mniejszy niż 2-3 centymetry), który przypomina powiększoną łechtaczkę (łechtaczka noworodka płci żeńskiej jest normalnie nieco powiększona przy urodzeniu)23.
  • Otwór cewki moczowej może znajdować się w dowolnym miejscu wzdłuż, nad lub pod penisem (spodziectwo). Może być zlokalizowany nawet tak nisko jak krocze, co dodatkowo sprawia, że niemowlę wygląda jak dziewczynka24.
  • Może występować mała moszna, która jest rozdzielona i przypomina wargi sromowe25.
  • Niezstąpione jądra często występują w przypadku nietypowych genitaliów26.

Inne objawy i powikłania

Oprócz atypowego wyglądu zewnętrznych narządów płciowych, mogą wystąpić inne objawy i powikłania:

  • Zaburzenia równowagi hormonalnej27.
  • Miesiączka rozpoczyna się wcześnie, późno lub wcale28.
  • Niepłodność – możliwość posiadania dzieci przez osoby z nietypowymi genitaliami zależy od konkretnej diagnozy. Na przykład, genetycznie żeńskie osoby z wrodzonym przerostem nadnerczy zazwyczaj mogą zajść w ciążę29.
  • Zwiększone ryzyko niektórych rodzajów nowotworów – niektóre zaburzenia rozwoju płciowego są związane ze zwiększonym ryzykiem wystąpienia pewnych typów nowotworów30.

Postęp i rozwój nietypowych genitaliów

Proces rozwoju zewnętrznych narządów płciowych zaczyna się od neutralnego zawiązka, który obejmuje guzek płciowy, fałdy płciowe i zatokę moczowo-płciową. Te struktury są następnie różnicowane w typowe męskie narządy płciowe pod wpływem androgenów, szczególnie dihydrotestosteronu (DHT). Natomiast dla rozwoju typowych żeńskich narządów płciowych kluczowy jest brak androgenów, aby zapobiec wirylizacji31.

Proces maskulinizacji początkowo neutralnych, niezróżnicowanych zewnętrznych narządów płciowych zaczyna się około 8-9 tygodnia ciąży, gdy jądra wytwarzają silny androgen DHT (dihydrotestosteron)32. Zaburzenie tego procesu może prowadzić do nietypowego rozwoju genitaliów.

W przypadku wrodzonych zaburzeń nadnerczy (CAH), które są jedną z najczęstszych przyczyn nietypowych genitaliów, występuje nadmiar androgenów w krytycznym okresie około 6-12 tygodnia ciąży, kiedy formują się zewnętrzne narządy płciowe. W tym czasie produkcja androgenów nadnerczowych powinna być przekierowana na produkcję kortyzolu, aby chronić żeński zawiązek narządów płciowych33.

Niedobór 21-hydroksylazy

Patologiczne mechanizmy niedoboru 21-hydroksylazy prowadzące do wirylizacji płodu żeńskiego (46,XX) in utero zostały dobrze opisane. Obejmują one nadmiar androgenów spowodowany brakiem aktywności 21-hydroksylazy w krytycznym okresie około 6-12 tygodnia ciąży34. Niedobór 21-hydroksylazy jest najczęstszą przyczyną wrodzonego przerostu nadnerczy (CAH).

Zmiany podczas dojrzewania

U niektórych osób z nietypowymi genitaliami objawy mogą być bardziej widoczne w miarę dojrzewania. Mogą wystąpić:

  • Przedwczesne lub opóźnione dojrzewanie płciowe35.
  • Nieoczekiwane zmiany podczas dojrzewania, np. rozwój piersi u chłopców lub nadmierne owłosienie u dziewcząt36.
  • Zaburzenia miesiączkowania – miesiączka może rozpocząć się wcześnie, późno lub nie występować wcale37.

Diagnoza nietypowych genitaliów

Nietypowe genitalia są zwykle diagnozowane przy urodzeniu lub krótko po nim. Czasami specjaliści medyczni mogą podejrzewać nietypowe genitalia jeszcze w czasie ciąży, gdy wyniki badań krwi płci nienarodzonego dziecka różnią się od obrazu ultrasonograficznego genitaliów dziecka38.

Diagnostyka dziecka z nietypowymi genitaliami zazwyczaj obejmuje:

  • Szczegółowy wywiad rodzinny i medyczny39.
  • Badanie fizykalne w celu sprawdzenia obecności jąder i oceny genitaliów40.
  • Badania krwi w celu pomiaru poziomów hormonów41.
  • Badania krwi w celu analizy chromosomów, które mogą pokazać płeć genetyczną (zazwyczaj XX lub XY). Te badania mogą również wykazać stany spowodowane zmianą genu, która wpływa na rozwój narządów płciowych42.
  • Czasami może być konieczne przeprowadzenie minimalnie inwazyjnego zabiegu w celu pobrania próbki tkanki narządów rozrodczych noworodka43.
  • Badania obrazowe, takie jak ultrasonografia czy rezonans magnetyczny, mogą pomóc w określeniu wewnętrznych struktur płciowych44.

W przypadku wrodzonych zaburzeń nadnerczy (CAH), które są najczęstszą przyczyną nietypowych genitaliów, diagnoza jest biochemicznie potwierdzana przez podwyższony poziom 17-hydroksyprogesteronu (17-OHP) w surowicy45.

Różnice w diagnozie – tabelaryczne porównanie

Cecha Genetycznie żeńskie (XX) Genetycznie męskie (XY)
Główne przyczyny Wrodzony przerost nadnerczy (CAH), ekspozycja na androgeny Zespół niewrażliwości na androgeny, niedobór 5-alfa reduktazy, zaburzenia rozwoju jąder
Typowy wygląd Powiększona łechtaczka, zrośnięte wargi sromowe Mały penis, proksymalne spodziectwo, rozdzielona moszna
Wewnętrzne narządy płciowe Zwykle żeńskie (jajniki, macica) Zwykle męskie (jądra), ale mogą być niedorozwinięte
Powikłania zdrowotne Przy CAH możliwa utrata soli zagrażająca życiu Zwiększone ryzyko nowotworów przy dysgenezji gonad
Płodność Często zachowana Często zaburzona

Znaczenie diagnozowania nietypowych genitaliów

Wczesna i kompleksowa ocena nietypowych genitaliów u noworodka jest niezbędna dla zrozumienia przyczyny i potencjalnych konsekwencji. Z jednej strony, ocena ta może prowadzić do wykrycia współistniejących, uleczalnych zaburzeń, takich jak niewydolność nadnerczy, która wymaga zastąpienia kortyzolu46.

Ważne jest również, aby zauważyć, że u 30% dzieci z różnicami/zaburzeniami rozwoju płciowego (DSD) mogą być zidentyfikowane zaburzenia innych układów narządów, wymagające opieki medycznej47.

Początkowe postępowanie w przypadku noworodka z nietypowymi genitaliami stanowi nagły przypadek społeczny i kliniczny. Zespół lokalny odgrywa kluczową rolę w koordynowaniu wstępnej oceny i badań oraz wspieraniu rodziców. Ważna jest wczesna dyskusja z bardziej specjalistycznym zespołem multidyscyplinarnym z doświadczeniem w dziedzinie pediatrycznej endokrynologii, genetyki i chirurgii, oraz z odpowiednim wsparciem psychiatrycznym/psychologicznym48.

W przypadku wielu DSD, długoterminowe wyniki chirurgiczne i psychoseksualne pozostają niepewne49.

Podsumowanie

Nietypowe genitalia stanowią rzadki stan, w którym zewnętrzne narządy płciowe noworodka nie wyglądają jednoznacznie męsko lub żeńsko. Mogą być spowodowane różnymi czynnikami, w tym zaburzeniami hormonalnymi i genetycznymi. Wczesna diagnoza i interdyscyplinarne podejście do leczenia są kluczowe dla zapewnienia optymalnych wyników zdrowotnych i psychospołecznych dla dziecka5051.

Rodzice dzieci z nietypowymi genitaliami potrzebują dokładnych informacji, wsparcia emocjonalnego i udziału w podejmowaniu decyzji dotyczących leczenia. Długotrwała opieka medyczna i monitorowanie potencjalnych powikłań są niezbędne dla tych dzieci w miarę ich dorastania52.

    Ambiguous genitalia is a rare condition where a child is born with outer genitals that do not clearly look either male or female. They may have features of both sexes or not be fully developed. The characteristics of the child’s genitals may not match their internal sex organs or their genetic sex. […] Ambiguous genitalia is common in children with differences of sex development (DSD). […] The male and female reproductive organs and genitals both come from the same tissue in the fetus. Ambiguous genitalia can develop if the process that causes this fetal tissue to become „male” or „female” is disrupted. This means the external genitals do look clearly male or female or may have characteristics of both. The physical appearance of people with this condition can vary widely. Very rarely, the physical appearance may be fully developed as the opposite of the genetic sex. For example, a genetic male may have developed the appearance of a female.

    Ambiguous genitalia also known as atypical genitalia is a rare medical condition where the newborn baby’s genitals are not clearly formed. They may either have underdeveloped organs or features of both genders. Causes in genetic females are Tumours, Prenatal exposure to male hormones and congenital adrenal hyperplasia […] Causes in genetic males are androgen insensitivity syndrome, impaired testicle development, abnormalities with testosterone and 5a reductase deficiency. Visible symptoms in genetically female newborns are: An enlarged clitoris, which may look like a penis, Closed labia, that resembles a scrotum, and lumps that feel like testes in the closed labia […] Visible symptoms in genetically male newborns are: A tube that carries urine and semen is not fully extended to the tip of the penis, a Small penis with the urethral opening closer to the scrotum, and the Absence of one or both testicles in the scrotum like a ball. Untreated Ambiguous genitalia leads to infertility and other types of cancer. Treatment of ambiguous genitalia starts with the determination of the sex of the little ones. The main goal of the treatment is to enable sexual function and fertility for the best possible outcomes. Medication is prescribed to balance the hormones in the body and surgery is made to preserve the sexual organs and create genitals.

The urethral opening (where urine comes out) can be anywhere along, above, or below the surface of the clitoris. The labia may be fused and look like a scrotum. The infant may be thought to be a male with undescended testicles. Sometimes a lump of tissue is felt within the fused labia, further making it look like a scrotum with testicles. […] In a genetic male (1 X and 1 Y chromosome), ambiguous genitalia most often include the following features: A small penis (less than 2 to 3 centimeters, or 3/4 to 1 1/4 inches) that looks like an enlarged clitoris (the clitoris of a newborn female is normally somewhat enlarged at birth). The urethral opening may be anywhere along, above, or below the penis (hypospadias). It can be located as low as the perineum, further making the infant appear to be female.

    Atypical genitalia can vary in appearance. Differences may depend on when during genital development the hormone changes that affected development occurred and the cause. […] Babies who are genetically female, which means they have two X chromosomes, may have: An enlarged clitoris, which may look like a penis. Closed labia, or labia that include folds and look like a scrotum. Lumps that feel like testicles in the fused labia. […] Babies who are genetically male, which means they have one X and one Y chromosome, may have: A condition in which the narrow tube that carries urine and semen, called the urethra, doesnt fully extend to the tip of the penis. If the tube opening is on the underside of the penis, the condition is called hypospadias. A very small penis with the urethral opening closer to the scrotum. One or both testicles missing in what appears to be the scrotum. Testicles that remain in the body, also called undescended testicles, and an empty scrotum that has the appearance of labia with or without a micropenis.

    Atypical genitalia (i.e., a genital phenotype that is neither clearly male nor female) are caused by the atypical development of chromosomal, gonadal, or anatomical sex. The complex group of disorders that cause atypical genitalia are called differences of sex development (DSD). […] The initial management of a neonate with atypical genitalia is a social and clinical emergency. The local team has a key role in coordinating the initial assessment and investigations, and supporting parents. It is important there is early discussion with a more specialist multidisciplinary team with expertise in pediatric endocrinology, genetics, and surgery, and with appropriate psychiatric/psychological support. For many DSDs, long-term surgical and psychosexual outcomes remain uncertain. […] DSD most commonly present in the newborn period and can be classified as sex chromosome DSD, 46,XY DSD, or 46,XX DSD. A subset of children with DSD present at birth with atypical genitalia and without other dysmorphic features. Many causes have a genetic basis. A very rare exception may occur when there is virilization of a 46,XX fetus by maternal virilizing tumors or maternal exposure to androgenic drugs.

    Ambiguous genitalia is a birth defect in which the outer genitals do not have the typical appearance of either a boy or a girl. […] Ambiguous genitalia may be a result of a disorder of sexual development (DSD), previously called intersex conditions. The ability to diagnose these conditions has improved greatly in recent years, due to advances in molecular genetics. […] Evidence about long-term outcomes for people with DSD who undergo gender assignment and reconstructive surgery is still lacking. […] Infants who are born with ambiguous genitalia represent a neonatal medical emergency for physical, social and psychological reasons. Immediate referral to an experienced multidisciplinary team (MDT) is essential. Urgent medical assessment is needed; for example, 75% of infants with CAH have associated salt-wasting nephropathy which can cause hypotension, collapse and death.

    For children with atypical genitalia, the sex organs may work properly in spite of how the genitals look on the outside. […] Results of surgery are often satisfying. But repeat surgeries may be needed. […] Children with atypical genitalia need ongoing medical care. […] If your baby has atypical genitalia, you may worry about the baby’s future. […] Your child may find ongoing counseling by mental health professionals helpful and may choose to be a part of support groups into adulthood. […] Not knowing the sex of your newborn right away might turn a hoped-for celebration into a stressful time. […] Consider waiting to make a formal announcement of the birth until testing is done and you’ve created a plan with advice from your medical team.
