Follicular fluid
From Wikipedia, the free encyclopedia
Follicular fluid is a liquid which fills the follicular antrum and surrounds the oocyte in an ovarian follicle. This fluid is rich in hyaluronic acid, and is used in a modified intracytoplasmic sperm injection (ICSI) called physiological ICSI (PICSI), semi-viscous and yellow in colour.[1] Its components come mainly from granulosa cells.[2]
