Andreas Vesalius
Andreas Vesalius documented early observations of the ovarian follicles in De Humani Corporis Fabrica.[1,2]
Ovarian follicles were subsequently described by anatomists including Gabriele Falloppio, Volcher Coiter, André du Laurens, Jean Riolan, Caspar Bartholin, Thomas Warton, Domenico de Marchertti.[2,3]
1672
Reinier de Graaf
Reinier de Graaf provided the first detailed anatomical description of ovarian follicles in De Mulierum Organis Generationi Inservientibus.[3]
1765
Albrecht von Haller
Albrecht von Haller introduced the term “ova Graafiana” in Elementa Physiologica Corporis Humani.[2]

Eponym:
The vesicular ovarian follicles are eponymously known as Graafian follicles, named after the Dutch physician and anatomist Reinier de Graaf (1641-1673). De Graaf studied at the Universities of Leuven, Utrecht, and Leiden and earned his medical degree in Angers, France, in 1665.[1] He later returned to the Netherlands and established himself in the city of Delft in 1666.[1] While de Graaf’s work encompassed a wide range of topics, including pancreatic secretions and the physiology of testicles, his studies of reproductive anatomy in individuals assigned female at birth were particularly influential.[1]
Scientific Contributions:
In 1672, de Graaf published De Mulierum Organis Generationi Inservientibus, in which he described the ovaries and proposed that they were responsible for producing the ovum.[3] In the book, de Graaf used the terms “vesicle” or “egg” to describe structures now recognized as ovarian follicles.[3] Although fluid-filled ovarian vesicles had been observed by other anatomists such as Vesalius and Falloppio, de Graaf did not claim their discovery. Instead, he acknowledged earlier descriptions and emphasized the continuity of anatomical knowledge.[2]

Some historical interpretations suggest that limitations in microscope resolution led de Graaf to equate the ovarian follicle with the ovum itself, but others argue that this is a misconception.[1] Karl Ernst von Baer, who identified the mammalian ovum in 1827, later argued that de Graaf used the term “egg” in a broader, dual sense, referring to the follicle as a functional unit rather than the oocyte alone.[1] The vesicular ovarian follicles were first referred to as “ova Graafiana” in the book Elementa Physiologica Corporis Humani by Swiss anatomist, Albrecht von Haller in 1765.[2]
