''X. laevis'' is also notable for its use in the first well-documented method of [[pregnancy test]]ing when it was discovered that the [[urine]] from pregnant women induced ''X. laevis'' oocyte production. [[Human chorionic gonadotropin]] (HCG) is a [[hormone]] found in substantial quantities in the urine of pregnant women. Today, commercially available HCG is injected into ''Xenopus'' males and females to induce mating behavior and to breed these frogs in captivity at any time of the year.<ref>Green, SL.

Nas tendas de mascota os 'X. laevis'' son con frecuencia confundidos con ''Hymenochirus'', que soin moi similares. Porén poden distinguirse doadamente polas seguintes características:
African Clawed Frogs are frequently mislabeled as [[African Dwarf Frog]]s in pet stores. The astute pet owner will recognize the difference, however, because of the following characteristics:
* Os ''Hymenochirus'' teñen os catro pés palmados, e o ''X. laevis'' só ten palmadas as patas de atrás.
* Dwarf frogs have four webbed feet. African Clawed Frogs have webbed hind feet while their front feet have autonomous digits.
* Os ''Hymenochirus'' teñen os ollos situados saos lados da cabeza, mentres que os ''Xenopus'' téñenos na parte superior.
* African Dwarf Frogs have eyes positioned on the side of their head, while African Clawed Frogs have eyes on the top of their heads.
* O fuciño dos ''Hymenochirus'' é bicudo e o dos ''Xenopus'' é máis arredondado.
* African Clawed Frogs have curved, flat snouts. The snout of an African Dwarf Frog is pointed.
