Growth Parameters of Uniquely Identified Anovulatory Follicles During Anovulatory (PCOS-Anov) and Sporadic Ovulatory Cycles (PCOS-Ov) in Women with PCOS

Parameter	PCOS-Anov (n = 12)	PCOS-Ov (n = 14)	Control (n = 12)

Growth rate, mm/d	0.60 ± 0.02 (0.56, 0.64)a	0.63 ± 0.02 (0.59, 0.67)a	0.63 ± 0.02 (0.58, 0.67)a
Static phase, d†	4.7 ± 0.2 (4.3, 5.1)a	4.7 ± 0.2 (4.3, 5.1)a	4.8 ± 0.3 (4.2, 5.3)a

Regression rate, mm/d	–0.58 ± 0.02 (–0.63, –0.53)a	–0.62 ± 0.03 (–0.67, –0.57)a	–0.56 ± 0.03 (–0.62, –0.50)a

Data are presented as least-squares mean ± standard error (95% confidence interval). Within rows, different superscript letters denote significant differences between groups, P < 0.05. Models included data from 235 anovulatory follicles in women with PCOS-Anov, 143 anovulatory follicles in women with PCOS-Ov, and 70 anovulatory follicles in controls. ^†Static phases were detected in 74% of follicles (175 / 235) in women with PCOS-Anov, 73% of follicles (104 / 143) in women with PCOS-Ov, and 77% of follicles (54 / 70) in controls.
