Have long felt that the very common complaints of reduced ejaculate volume/reduced ejaculate consistency were somehow connected to the very common low FSH values most PFS sufferers have, regardless of their total T status. The low FSH values in PFS sufferers don’t often respond to clomiphene stimulation, despite strong response to LH (and thus T) production.
This paper appears to prove a strong connection between the readings and issues (or paucity thereof), and also appears to indicate that testosterone shots may not be the best treatment for PFS men having ejaculatory issues or concerns.
The abstract goes on to hypothesize that in order to achieve quantitatively normal levels of spermatogenesis a man needs both normal FSH and LH values.
