Do not know. But TRT reduced my preg levels 10 years ago.
250iu hCG SC EOD is a LH replacement dose, so that is all that you can hope for. For older guys preg levels would not be youthful for obvious reasons.
If DHEA-S is OK, there must be decent amounts of preg on board to support preg-->DHEA.
Preg is created in all cells, in the mitochondria as cholesterol-->preg, so testes are not the only source. This gets to CoQ10 and other aspects of mitochondrial function which leads into the possible problems with statin drugs that some have the genetics for. Also note that fT3 regulates mitochondrial as part of body's temperature control loop and rT3 can block fT3. So your thyroid health has an obvious lever on preg and energy levels.
