Following a subcutaneous injection of 100 μg of synthetic luteinizing hormone releasing factor (LRF), no increase was seen in the plasma luteinizing hormone (LH) in 3 subjects (1 nursing, 2 not nursing) studied in the first 3 wk after delivery. When studied again 6 wk or later after delivery, a normal increase was observed in plasma LH following LRF administration. These studies suggest that the pituitary gland might be temporarily resistant to stimulation by LRF in the early postpartum period.
