As I am sure many of you here are aware the cause of Propecia based problems is finasteride.
Finasteride is an anti androgen and lowers dihydrotestosterone (DHT).
DHT is an androgen like testosterone.
The definition of hypogonadism is a lack of testosterone and/or its metabolites.
One of those metabolites is DHT.
The problem when many men go and see their doctor or endocrinologist to have a hormonal evaluation is that DHT is often not tested, yet this is the specific hormon directly affected by Finasteride.
Many men who have hypogonadism are told that they are eugonadal because they have low normal testosterone, but that it is not overtly low, but this is to misdiagnose the condition givent he definition of hypogonadism. It is to miss exactly what it is that Finasterid targets.
DHT is responsible for positively affecting the male endocrine balance in favor of androgens and preventing and estrogen to androgen bias ratio that allows for the development of gynecomastia. It is responsible for the achievement and maintenance of erectile function and it is required for libido.
A loss of DHT is obviously problematic.
But sometimes even where DHT is tested post Finasteride use it turns out to be normal. In such cases where symptomatic problems remain I have found a second mechanism of action that has occureed in the pathology of many men who have used Propecia and other Finasteride based products.
I have found that often, although serum/total testosterone is not reduced below the normal range, often Sex Hormone Binding Globulin (SHBG) is often elevated into the upper normal range, something usually only seen in elderly men.
Such elevations of SHBG tend to significantly and adversely reduce the crucial level of free testosterone.
It is often then the case that although such men do not appear to be hypogonadal via a serum/total testosterone testm, they often do in fact have and appear to be hypogonadal or boarderline hypogonadal when the crucial free testosterone test is undertaken.
There are two treatment that have the potential to rectify these problems that can be prescribed by forward thinking endocrinologists/andrologists, the first is Andractim DHT gel, the second is Danazol which reduces SHBG.
In the hands of highly qualified aforementioed doctors, Finasteride problems can be overcome.
