[The dynamics of pulsatile LHRH (GnRH) secretion].

A review of the features of RHLH, especially of the pulsating secretion, which is very important to the correct function of the reproduction system, is presented. Now it is accepted that this pulsating secretion is the producer of the episodic release of gonadotrophins, the gonadal steroids being the modulator of the frequency and the extent of the LHRH pulses. Several experiences showed that changes in the pulse frequency of GnRH, can dynamically modify the seric concentration of LH and FSH.
