Secretion of neurophysins during luteal regression in the goat.
In non-pregnant goats, ovariectomy on day 12 of oestrous cycle resulted in parallel decrease of oxytocin and progesterone jugular concentration. Similarly, luteolysis, indicated by decreasing progesterone concentration, was accompanied by simultaneous release of oxytocin and oxytocin-associated neurophysins (mean of neurophysin I and II). It is suggested that the neurophysins are secreted concomitantly with oxytocin by the ovary during luteal regressions in the goat.
