abstract：:Daily nocturnal (N) and diurnal (D) surges of PRL are characteristic of a pseudopregnancy (psp) induced by cervical stimulation (CS). These semicircadian surges persist for 13-14 days, after which time they cease, and psp ends. The purpose of this study was to describe the involvement of the ovarian steroids in the ma...
