Figure 2.

Graphical representation of differences in mechanical-force-mediated stimulation between the drug-free IVA and WOLI procedures. Drug-free IVA and WOLI procedures receive different types of mechanical manipulation, which vary in the scale and extent of tissue damage surrounding ovarian follicles and presumably the scope and speed of tissue regeneration in ovarian stroma. As such, they may lead to different patterns of follicle recruitment and growth. The orange cells in insets represent granulosa cells that surround the oocytes.
