LH pulses stimulate progesterone release in mid-luteal phase

Serum concentrations of luteinizing hormone and progesterone during 24 hours of blood sampling at 10-minute intervals in a typical female studied during the mid-luteal phase. There is a significant correlation between LH pulses and increased serum progesterone concentrations. To convert serum progesterone values to nmol/L, multiply by 3.18.
