Interesting study, have not seen it posted here:
On the role of dihydrotestosterone in regulating luteinizing hormone secretion in man. - PubMed - NCBI
"Nevertheless, plasma levels, 8-10 times higher than normal were achieved and maintained for 3 months with no apparent effect on plasma LH. Therefore, it seems reasonable to conclude that cirulating DHT has little physiological impact on LH secretion. However, DHT has been shown to increase the pituitary sensitivity to exogenous LRH (12). In our long term study, this effect could compensate for an inhibitory effect of DHT at the hypothalamic level and, therefore, explain the unchanged LH secretion. In spite of the constant level of LH, plasma T and E2 dropped drastically by 50% during DHT treatment."
