Learn the difference between in vivo and in vitro, two terms that describe whether a study or procedure is done in a living organism or outside of it. Find out the pros and cons of each method and see real-life examples from science and medicine.
In vitro (meaning in glass, or in the glass) studies are performed with cells or biological molecules outside their normal biological context. Colloquially called " test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates.
IVF (in vitro fertilization) is a type of fertility treatment where eggs are combined with sperm outside of your body in a lab. It's a method used by people who need help achieving pregnancy. IVF involves many complex steps and is an effective form of assisted reproductive technology (ART).

Discover the key differences between in vivo and in vitro methods in biology and medical research. Understand their definitions and applications.
In Vitro, a Latin term meaning "in glass," primarily denotes experiments that are conducted outside of a living entity, usually in controlled environments like Petri dishes or test tubes. Conversely, In Vivo, which translates to "within the living," pertains to studies or tests done within or on live organisms, from tiny microbes to whole animals.
in vitro Term referring to a measurement or a process taking place in a test tube. Example: the measurement of the cholesterol content of the crystalline lens done in a test tube.
