Húgycselváltozások

Húgycselváltozások refers to a phenomenon observed in some species of amphibians, particularly frogs and toads, where the cloaca, a single posterior opening for the intestinal, urinary, and reproductive tracts, undergoes visible changes during their reproductive cycle. These changes are often associated with sexual maturation and the breeding season. In males, the cloaca may become more prominent or swollen, reflecting increased activity of the reproductive organs and the production of sperm. In females, the cloaca can also enlarge, particularly when they are receptive to mating and ready to lay eggs. These external modifications are subtle indicators of the animal's physiological state and readiness for reproduction. The specific appearance and timing of these changes can vary between species and even among individuals within a species. Observing these húgycselváltozások can provide insights into the reproductive biology and behavior of these amphibians.
