Representative profiles of follicle growth and reproductive hormone concentrations during a sporadic ovulatory cycle in women with PCOS-Ov (n = 3) and an interovulatory interval (IOI) in controls (n = 1). Profiles exemplify cyclic (A) and continuous (B) recruitment in PCOS-Ov and compare an IOI in 1 woman with PCOS-Ov (C) to an IOI in 1 control (D). Each uniquely identified follicle is represented by a different gray-scale line. All follicles that grew to ≥7 mm could be individually tracked over time using the Identity Method. Asterisks indicate ovulatory follicles. Abbreviations: E2, estradiol; FP, follicular phase; FSH, follicle-stimulating hormone; LH, luteinizing hormone; LP, luteal phase; M, menses; P4, progesterone.
