Daily profile of urinary FSH levels across an entire menstrual cycle in 8 premenopausal women with DOR and 11 older perimenopausal controls. Compared with the older controls, the DOR cases demonstrate significantly lower FSH levels in the early follicular phase (P < 0.001). The amplitude and duration of the FSH surge are comparable in the two groups. Note: centering of cycles relative to the LH surge (day 0). FSH, follicle-stimulating hormone; DOR, diminished ovarian reserve; LH, luteinizing hormone.
