Bold values indicate a mild (r ≥ 0.1) or greater marginal correlation. P values are provided within parentheses.

^*Denotes a moderate marginal correlation (r ≥ 0.30).

E1-C, estrone conjugates; E3, estriol; FSH, follicle-stimulating hormone; LH, luteinizing hormone; NS, not significant (P > 0.05); Pg, progestagens; tLG, total large follicles; tMD, total medium follicles; tSM, total small follicles; tVSM, total very small follicles.
