Resumen
Las emisiones nocturnas (NE), o sueños húmedos, son comunes durante la pubertad masculina, y ocurren en el 70-90% de los adolescentes. Estas eyaculaciones involuntarias son un evento fisiológico normal con relevancia cultural y clínica, aunque persisten conceptos erróneos.
Área de la Ciencia:
- Salud reproductiva y salud reproductiva.
- Medicina de la Adolescencia y el Adolescente.
- Urología Urología Urología.
Sus antecedentes:
- Las emisiones nocturnas (NE), comúnmente conocidas como sueños húmedos, son eyaculaciones involuntarias durante el sueño.
- Si bien es un aspecto normal de la pubertad masculina, las NE están asociadas con incertidumbres persistentes con respecto a su base fisiológica, prevalencia y importancia clínica.
Objetivo del estudio:
- Realizar una revisión sistemática de la literatura existente sobre las emisiones nocturnas.
- Resumir los datos epidemiológicos, explorar los mecanismos fisiológicos, analizar las perspectivas culturales y evaluar la relevancia clínica.
Principales métodos:
- Búsqueda sistemática de literatura de PubMed y EMBASE (hasta abril de 2025), incluida la literatura gris y los estudios no traducidos al inglés.
- La inclusión de datos de las bases de datos de FAERS y EudraVigilance para las NEs relacionadas con las drogas.
- Evaluación del riesgo de sesgo utilizando la Escala de Newcastle-Ottawa y la evaluación narrativa de obras cualitativas.
Principales resultados:
- 157 fuentes incluidas; la primera NE ocurre típicamente entre los 12.6-15.6 años, con una alta prevalencia (70-90%) en adolescentes.
- La prevalencia varía entre culturas, es menor en algunas cohortes asiáticas y rara en el deterioro neurológico; los datos de frecuencia son inconsistentes.
- Las EN no son liberaciones compensatorias; ocurren con/sin sueños eróticos, independientemente del control supraspinal; papel potencial en el diagnóstico de anejaculación y reproducción asistida.
Conclusiones:
- Las emisiones nocturnas son un fenómeno fisiológico casi universal con importantes dimensiones culturales, educativas y clínicas.
- Las NE siguen siendo relevantes para el desarrollo sexual, la salud de los adolescentes y contextos diagnósticos específicos.
- La investigación prospectiva adicional de alta calidad es esencial para aclarar los mecanismos y las implicaciones.

02:55The Evidence for Evolution
48.4K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

526
Sigmund Freud revolutionized our understanding of dreams by proposing that they are a window into the unconscious mind. According to Freud, dreams are not mere stories our minds create while we sleep but are profoundly meaningful narratives about our hidden desires and fears. He introduced two key concepts: manifest content and latent content. The manifest content is the actual content and imagery of the dream — what we remember when we wake up. The latent content, however, represents the...

01:17The Scope of Physics
53.5K
Physics is concerned with the interactions of energy, matter, space, and time, in order to discover the underlying mechanisms that underpin all phenomena. The word "physics" comes from the Greek word "phúsis", which means nature. Physics seeks to comprehend the natural world around us at its most fundamental level. It emphasizes the use of quantitative laws to do this, which could be valuable in other fields that want to push the performance boundaries of present...

01:10Lucid Dreaming

Lucid dreaming is a unique state of consciousness where an individual realizes they are dreaming while still in the dream. This awareness allows them to manipulate their dream environment consciously. Researchers like Stephen LaBerge have significantly contributed to the understanding of lucid dreams, highlighting that during these dreams, certain areas of the brain, such as the prefrontal cortex, that involve self-awareness and thought evaluation show increased activity.

02:39Emission Spectra
76.5K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains.
