Here is what the doc had to say about the ole gyno so far:
" The thyroid tests, both the T4 and TSH were normal. The male hormone level,i.e. serum testosterone was low-normal at 3 and this is a possible causae, although the FSH, which is another hormonal marker was normal at 1.8. This probably indicates that the testosterone level, while low-normal,is nevertheless normal and not a cause of the problem."

They want me to stop in so they can take more blood to check serum Prolactin levels and human chorionic gonadotrophin beta fraction blood levels.

I'm not to up on my FSH and different types of test serum levels...somebody school me..or point me to a webpage.........gracias.........456

He's basicly looking at your HPTA axis to see if there is a problem with the negative feedback loop that regulates T levels.

At puberty, pulsatile secretion of GnRH causes the anterior pituitary to produce LH and FSH. Circulating LH induces the Leydig cells of the testis to produce testosterone, with the resultant development of secondary sex characteristics. As the level of testosterone rise in the circulation, there is a negative feedback on the production of GnRH at the hypothalamic level, and LH and FSH at the pituitary level.

A high intratesticular level of testosterone is required for sperm production. The levels in the seminiferous tubules remains high due to the proxitimity of production in the Leydig cells, and well as by binding in the tubules by androgen binding-protein (ABP). This binding to ABP probably also prevents fluctuation of the levels, by maintaining a reservoir of hormone immediately available to buffer changes in production. Although testosterone is the only absolute requirement for sperm production, FSH has a promotional effect, and quantitatively normal spermatogenesis requires the action of FSH on the Sertoli cell. When sperm production is proceeding in a quantitatively normal manner, a peptide hormone called inhibin is released into the circulation (also by the Sertoli cell) and is responsible for negative feedback of FSH (but not LH) production by the pituitary
Estradiol (E2) is produced by esterification of testosterone. The rate of conversion of T to E2 can be increased in obese men and in men with liver failure. Elevated levels of E2 can down regulate the hypothalamic-pituitary-gonadal axis, resulting in decreased gonadotropin secretion and decreased circulating T levels.

Sure Gear:

[ FSH + T ] - [ E2 ] = BFMG

T = 1000mg/wk
max

E2 = near zero

BFMG=Big Friggin Muscle Growth

That's basicly the only formula you need to memorize bro,lol
