Follicularfluid
The transudate of plasma across the follicular wall is the initial source of follicular fluid, which builds up in the antrum, created by the fusion of tiny fluid-filled pockets.
The metabolic activity of the cells within the follicle changes the composition of the follicular fluid. The follicular fluid contains proteins, amino acids, carbohydrates, enzymes, and hormones (sex steroids, prostaglandins, and gonadotropins). The follicular fluid is essential for the maturation of oocytes, ovulation, granulosa cell regulation, and egg transport. The oviduct receives large volumes of follicular fluid, which is released during ovulation and contributes to the conditions that allow for sperm capacitation, fertilization, and the early development of embryos. The follicle and the oocyte grow at the same time when certain unique components in the follicular fluid appear. The purpose of the immunoglobulins (IgA and IgG) present in the follicular fluid is unknown.21.5
