honestly i think some doctors are morons. plain and simple
the doc's probably just reciting some general recommended dose that he came across once during his studies
why risk LH desensitization and a drastic E2 spike with 3000iu EOD when 500iu can serve the purpose?
Well I think some people on this forum are morons for not listening to their doctors!!
The reason that people on the internet say 250 or 500 iu is because of a guy that has his login name as Dr. Swale. He was the first guy that said to use that amount for control of testicular shrinkage. Doctors aren't stupid they are cautious. You have no reason to say that the dose prescribed by his doctor will cause desensitization. And you have no evidence that 500 iu will do the job. You're just repeating what you have seen posted on the forum by people that are repeating what they have read. Exactly what you claim for "moron" doctors.
Here is facts to ponder:
Desensitization of mouse Leydig cells in vivo: evi...[Biol Reprod. 1985] - PubMed Result
And I will save you the trouble of reading it by cut and pasting the conclusion.
"In conclusion, our data indicate that the impaired steroidogenesis in mouse Leydig cells desensitized in vivo by a single injection of hCG is the result of a depletion in cellular cholesterol, rather than of an impaired conversion of cholesterol to testosterone."
This study shows that when the leydig cells stop producing testosterone after a single large injection of Hcg is because they have used up all the available cholesterol. And if you didn't know, and I suspect you didn't, cholesterol is the basic building block of testosterone. The leydig cells convert cholesterol into testosterone.
So there is no desensitization only a reduction of the available cholesterol. The leydig cells are fine they just can't make any more testosterone because they don't have any cholesterol.
There are studies that have looked at low dose Hcg but they only checked intratesticular testosterone. Not bound or free testosterone in the rest of the body. So any information you try to gain from the low dose studies is useless because you have idea how much testosterone is available in the body. And in my opinion it is natural for levels to increase when you check the intracellular area that is right agaisnt the cells producing what you are checking for.
So I say follow your doctors advice he knows more the the "morons" that just repeat what they have read do.
And just for fun here is a link to a study that check on men that were shutdown from 12 weeks of 200mg per week of testosterone enanthate. It took six months of 5000 iu three time a week for SIX MONTHS to get them back to normal sperm production.
Stimulation of sperm production by human chorionic gonadotropin after prolonged gonadotropin suppression in normal men -- Matsumoto and Bremner 6 (3): 137 -- Journal of Andrology
And by the way there was no mention of anybody in the study having desensitization of the leydig cells after the 5000 iu three times a week for six months. SO your your assertion that 3000 iu once will cause desensitization is baseless.
