High dose test impairs sperm 'suppression'!

[Mr I]

Not gonna go into detail but this is one of those pieces of study that much information can be extrapolated from Also raises many questions, this is a Mr I study post so you can be sure its worth while:thumup:

So its birth control right? Good, babies are shit. :D

Not exactly, in fact, potentially not at all. There are different things one can take from the studies collectively, not just these which seem to suggest that there isn't much of a strong correlation between dozez and suppression of your natural test.

There is one further aspect with regard to sperm, higher levels of exogenous test reduce its effectiveness in shutting down sperm count, I.E low dose test is better at making you infertile.

On a bro science note, Palumbo reckoned that the reproductive system need testosterone around to make the good sperm. If you took a little test this shut you down in the testes and the exogeneous test you shot in you system was so diluted by the time it got into your blood that there wasn't blood level test around the testes etc to finish the sperm making process.

BUT

If you shot like 1000mg a week of test then even after the pass through the liver the blood levels were sufficient to bathe the testes in testosterone and positively affect the reproductive process of sperm.

See the summary intro in 36.2, question is, what are supraphysiological dozez of test? my guess is 1000mg plus

getting a bit ahead of me bro.

so basically its saying if your taking test at only like 100mgs per week your spearm count will be low. its also saying that if your taking test at like 1000mgs per week your sperm count will be low. BUT if you are taking like 500mgs of test your sperm count will be normal??

The study is saying your sperm count will be lowest if you take low dose test for long enough. Higher doses, say 300mg pw are less effective at reducing sperm count.

There is a separate school of though which I had thought was bro science coming from palumbo that if you take 1000mg (supraphysiological) dose of test a week, your effective sperm count will actually stay same or increase.

I haven't seen a study to clearly state this, but there is circumstantial evidence that it exists from the inference of the intro of the url post 5 for chapter 36.2 which says something like 'unless as supra-physiological doses, exogenous test won't provide enough localised concentrated test in the testes to trigger what is needed. Note the words 'unless at supra-physiological' so counter intuitively its actually saying that AT SUPRA-PHYSIOLOGICAL LEVELS of exogenous test, there WILL be sufficient localised concentration of testosterone in the blood and testes to create good sperm.

The tone is one of already acknowledged fact, so where's that study?

But it seems to back Palumbo's claims

I'm not sure how that works in all because I know people who have conceived while ON gear,,,and had perfectly healthy children I might add.

The sperm is merely the male DNA, just the trigger for the egg to become embryo, doesn't really matter what state the sperm is in it just needs to get there

actually many years ago test was looked into as birth control.

Your a bit behind bro, thats a known already, if you read the thread and articles you'll understand better

to lazy to read it and not intrested actually I have to many damn kids already,lol

yes I know its behind thats why I said many years ago

to clarify both our understandings;

1) test is not a reliable contraceptive
2) more test is less effective (known) and 'possibly' adverse, in supressing sperm, than low test dose which serves to shut your own down and leave your testes with very little (natural or exogeneous) local test blood concentration.

i am going to have to disagree complelty.:rofl:
