WebWhen GnRH is released in a pulsatile manner, it sustains the transcription of GnRHR mRNA as well as expression of GnRHR protein in the pituitary gonadotropes. While the continuous infusion of GnRH results in a desensitization of gonadotropes due to the reduction of the expression of GnRHR . It can be suggested that an inflammatory-dependent ...
