title: Temporal relationship between cell nuclear progestin receptor levels and sexual receptivity following intravenous progesterone administration.
abstract: This study was designed to assess the temporal relationship between the appearance and retention of cell nuclear progestin receptors in hypothalamus and the facilitation and decline of feminine sexual behavior following an i.v. injection of progesterone (P). Nuclear translocation of progestin receptors preceded the earliest appearance of behavior. The behavioral effects of P outlasted the nuclear progestin receptor elevation by several hours. Our results are consistent with the idea that P-induced effects on feminine sexual behavior involve genomic activation.
