{{Short description|Structure formed from the primary sex cords in females}}

The rete ovarii ({{plural form}}: retia ovarii) is a structure formed from the primary sex cords in females.{{cite web |title=Development of the Ovaries |archive-url=https://web.archive.org/web/20120614070308/http://sprojects.mmi.mcgill.ca/embryology/ug/Reproductives/Normal/girldevelop.html |url=http://sprojects.mmi.mcgill.ca/embryology/ug/Reproductives/Normal/girldevelop.html |archive-date=2012-06-14 |url-status=dead |publisher=Internet Archive}}

It is the homologue of the rete testis in males.[https://medical-dictionary.thefreedictionary.com/rete+ovarii Definition: rete ovarii from Online Medical Dictionary] It is a narrow hilus, at which nerves and vessels enter the ovary. In the medulla of the mammalian ovary near the hilus are small masses of blind tubules or solid cords—the rete ovarii—which are homologous with the rete testis in the male. The microscopic right ovary of birds usually consists only of medullary tissue.

The rete ovarii is important in the control of meiosis in the maturing ovary. Cells of the rete ovarii also differentiate to form granulosa cells. The rete is also attributed with secretory capacity, a hypothesis supported by the observation of secretory material in the lumen of rete tubules in several species.{{Cite journal |last1=Odend'hal |first1=Stewart |last2=Wenzel |first2=James Guthrie Wheeler |last3=Player |first3=Emory Craig |date=September 1986 |title=The rete ovarii of cattle and deer communicates with the uterine tube |url=https://pubmed.ncbi.nlm.nih.gov/3767001/ |journal=The Anatomical Record |volume=216 |issue=1 |pages=40–43 |doi=10.1002/ar.1092160107 |pmid=3767001 |s2cid=23132112 |issn=0003-276X}}
