Fig. 3From: Effect of ovarian growth factors on ultra-structural maturation in frozen human immature oocytes after in vitro maturation: a comparative studyControl 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). Mitochondria are generally rounded and provided with few peripheral or transverse cristae. Note the presence of complexes between mitochondria and vesicles of SER (arrows). The MV complexes were increased in IVM oocytes; Mitochondria-smooth endoplasmic reticulum (M-SER aggregates) varied in size and shape.
