Follicular Growth in Maturational Stages

Semi-log bar graph of follicle diameter versus follicular stage, Note the significant growth of the human Graafian follicle compared to other mammalian species.

Asterisk indicates values from previously published data for reference[1], and therefore do not include error bars. Values are the mean ± standard error.
