From: Effect of ovarian growth factors on ultra-structural maturation in frozen human immature oocytes after in vitro maturation: a comparative study

Fig. 2

Ultrastructure of control oocyte (a), fIVM α-MEM (b), vIVM α-MEM (c), fIVM B.M (d), Vıvm B.M (e), fIVM O.F (f), vIVM O.F (g). Round cortical granules with an electron-dense arrival located just underneath the oolemma. The number of cortical granules was reduced in vIVM oocytes rather than f IVM. Note the increased compaction of the inner aspect of the ZP in vIVM groups. Several long Microvilli are seen in the control oocytes (a) and fIVM O.F (f). Also, long microvilli were dispersed on the oolemma of fresh IVM oocytes (b, d, f) rather than in vitrified IVM oocytes (c, e, g), while in the vitrified IVM oocytes, the oolemma was determined to have irregular and little microvillous arrangements. ZP zonapellucida; mv microvilli; CG cortical granules; PVS perivitelline space
