luteinization

 [loo″te-in″ĭ-za´shun]
the process taking place in the luteal cells of graafian follicles that have matured and discharged their eggs: the cells become hypertrophied and there is vascularization and lipid accumulation (the latter in some species giving a yellow color), the follicles then become corpora lutea.
Luteinization, beginning after rupture of the ovarian follicle in ovulation (A) and progressing through vascularization and hypertrophy of the maturing corpus (B, C); it is followed by regression (D) to the corpus albicans (E). From Dorland's, 2000.

Histology showed spindle cells arranged in interlacing bundles interspersed with focal plump cells with luteinisation. The prevalence of sexcord stromal was comparable with other studies.
