Female ejaculation: An update on anatomy, history, and controversies.

Female ejaculation is a contentious topic. From a review of the literature, history indicates that it is not a modern concept; some females were aware of it in times past without understanding the role of the fluid or composition of the ejaculate. Over time, scholars experimented, mainly with anatomical studies, in an attempt to identify the source of the ejaculate and explore its physiological and anatomical benefits for the female sexual experience. Despite these studies, views about female ejaculation remain controversial and inconsistent, with no clear conclusion as to its function. This review discusses the history of studies of female ejaculation and presents various hypotheses from an anatomical and physiological perspective. After reviewing 44 publications from 1889 to 2019, it became apparent that clinical and anatomical studies conducted during recent decades provide substantial evidence in support of the female ejaculatory phenomenon. Anatomical studies have shown that the ejaculate originates in the paraurethral (Skene's) glands, but its composition has been debated. Female ejaculate differs from urine in its creatinine and urea concentrations. The fluid also contains prostate specific antigen (PSA) and could have antibacterial properties that serve to protect the urethra. While the specific function of female ejaculation remains a topic of debate, there is sufficient evidence to support the existence of the phenomenon.

Absceso de glándula de Skene en recién nacida / Skene gland abscess in a newborn girl

Los quistes de las glándulas de Skene constituyen una entidad infrecuente, reportándose menos de 50 casos en la literatura. Frecuentemente pasan desapercibidos, a no ser que infectan u obstruyen, dando lugar a Skenitis. Se presenta el siguiente caso con el objetivo de demostrar la importancia del ultrasonido en masas interlabiales de la recién nacida pues permite determinar características sonográficas en quísticas o sólidas y realizar un adecuado tratamiento quirúrgico. El caso clínico corresponde a una recién nacida femenina que al momento de su nacimiento se detecta una masa de color blanquecino, con algunos vasos visibles, interlabial, que protruía a través del introito vaginal. Se realiza ultrasonido, se constata la presencia de una imagen quística. Se interviene quirúrgicamente recibiendo diagnóstico histológico de quiste abscedado de una glándula de Skene. Se concluye que resulta útil la realización del ultrasonido en masas interlabiales del neonato para determinar tipo tratamiento.(AU)

Cysts of Skene glands constitute an unfrequented entity, being reported in less than 50 cases in the literature. They frequently happen unobserved, unless they infect or obstruct, originating Skenitis. The following case as presented with the objective to show the importance of ultrasounds in inter labial masses of the newborn girl because it allows to determine ultrasonography characteristics in cystic and solid masses and carry out an adequate surgical treatment. The clinical case corresponds to a female newborn that in the moment when she was born, a whitish mass was detected with some visible inter labial vessels, that protruded through the vaginal introitus. An ultrasound was performed, and the presence of a cystic image was verified. She was operated and the histologic diagnosis was an abscessed cyst of the Skene gland. To conclude it can be said that the performance of an ultrasound in interlabial masses of newborns is useful to determine the type of treatment.(AU)

Quiste de conducto de Skene en niñas: A propósito de 2 casos clínicos / Skene duct cyst in female newborns: Case reports

Introduction: The Skene duct cyst, classified as a paraurethral cyst, is a rare congenital abnormality in female neonates and it may manifest throughout the course of life. The incidence varies from 1 in 2000 to 3000 female births. Objective: To expose the characteristics and symptoms of a Skene duct cyst at different stages of child development in order to carry out a timely suspicion and diagnosis. Case report: The first case is a female newborn who presented a painless yellowish tumor adjacent to the urethral meatus, which drained spontaneously; the second case is a teenager who consulted due to leucorrhea for a year and a three-centimeter diameter paraurethral injury between the labia minora, which required surgical treatment and study of the paraurethral mass. Conclusions: Based on the literature review, we concluded that the frequency of Skene duct cyst is higher than the number of reported cases. Cyst removal, marsupialization, puncture and aspiration are all effective treatment methods. Spontaneous drainage is also appropriate in certain cases. We suggest the use of the least aggressive technique according to each case.

Introducción: El quiste del conducto de Skene, se describe dentro de los quistes parauretrales, siendo una rara anomalía congénita descrita en neonatos de sexo femenino, que se puede presentar en el transcurso de la vida. La incidencia varía de 1 cada 2.000-3.000 recién nacidos vivos femeninos. Objetivo: Dar a conocer las características y formas de presentación del quiste del conducto de Skene en distintas etapas del desarrollo del niño para su sospecha y diagnóstico oportuno. Casos clínicos: Se presenta una recién nacida con una lesión tumoral amarillenta, adyacente al meato uretral, no dolorosa, que drena espontáneamente y un segundo caso de una adolescente que consulto por leucorrea de un año de evolución, con una lesión parauretral de tres centímetros de diámetro entre labios menores, que requirió tratamiento quirúrgico y estudio de la masa parauretral. Conclusiones: Basado en la revisión de la literatura, concluimos que la frecuencia de los quistes de conducto de Skene es más alta que el número de casos informados. La extirpación, marsupialización, la punción y aspiración del quiste son todos métodos eficaces de tratamiento. El drenaje espontáneo también es una conducta apropiada en ciertos casos. Se sugiere utilizar la técnica menos agresiva acorde a cada caso.
