Now, this only is a not too far fetched approach to dealing with low T if ones nuts are still functioning. It also assumes that one is satisfied with "middle of the road" T levels.
But more and more studies are validating what makes logical sense for some; that use of Clomid might be a better alternative than going straight to T replacement.
Latest study: http://www.ncbi.nlm.nih.gov/pubmed/22044663, "Outcomes of clomiphene citrate treatment in young hypogonadal men".
Estrogen levels increased a bit of course, because many also need to control the T -> E conversion as T levels rise. Logically, and assuming correct amounts are dialed in, use of AI with Clomid might be a decent approach. For awhile at least.
