What is a mature follicle
During superovulation (used during IVF treatment), the goal is to stimulate the ovaries to develop several mature follicles at once. An ultrasound. The follicle is a functional anatomical structure which forms part of the ovary and the egg is the cell that will mature in a microscopic part of inner. However, once hormonal signals trigger the development of follicles and they start to mature and grow, they become known as antral follicles. The mature follicle is often called the Graafian follicle. The gonadotropic hormones, follicle stimulating hormone (FSH) and lutenizing hormone (LH), which are released by the anterior pituitary, activate this maturation process and stimulate the primary oocytes to complete meiosis I to form a polar body and a secondary oocyte. Sep 01, · The follicle is a functional anatomical structure which forms part of the ovary and the egg is the cell that will mature in a microscopic part of inner wall of a follicle over spontaneous or stimulated ovarian cycle in normal conditions. Furthermore, the follicle contains other cell types which produce oestrogen required for normal development of the egg maturation/5(29). In a natural (unstimulated cycle) or Clomiphene Citrate cycle, mature follicle size is between 18 - 30 mm. If triggered, these cycles are typically triggered when follicle size is between mm (dependent of the practice and IVF lab). In a gonadotropin cycle, mature follicle size is between 16 - 20 mm.
