high testosterone 1000mg and fertility

[PrettyPlease?]

FSH is not not needed for spermatogenesis to occur. What is needed are intratesticular concentrations of testosterone which high levels of exogenous testosterone can provide.

Both FSH and adequate testosterone levels are needed for spermatogenesis. They teach this in college physiology, and the first link you posted states it clearly at the end of the first paragraph.
So yes, a large shot of exogenous test will boost fertility temporarily, until the negative feedback loop shuts off FSH production.
You could also use HMG to counteract that last problem.

You are misinterpreting it. The first paragraph says that FSH has a role in induction and maintenance. NOT that it is REQUIRED.

I am very well aware of what they teach in physiology classes thank you. Even if I wasn't that is a poor argument, unless you are asserting that everything a teacher tells you is correct?

I suggest spending more than 9 minutes reading and responding to the links I posted. Let it sink in and digest a little before responding.

You're kinda splitting hairs here. Fine: for ideal healthy sperm production, you need both. I don't care if one or the other may maintain some degree of sperm production. What is your angle here, anyway? Are you advocating that we use 1,000 mg of testosterone alone when trying to conceive?

I mentioned that to make evident that this commonly accepted fact in the medical/scientific community, and not something controversial that I am pulling out of my ass. And it was from a modern textbook, not the professor's mouth.

And I suggest that you stop getting so worked up and assume a more respectful tone (especially with staff members who have dedicated countless hours to helping members, and really don't appreciate being rudely told off by some random new member).

Let me phrase a question that might help. Why is exogenous testosterone not considered an effective male contraceptive? Shouldn't spermatogenesis not continue once " the negative feedback loop shuts off FSH."

It is an effective male contraceptive, for most.

Male hormonal contraception: suppression of spermatogenesis by injectable testosterone undecanoate alone or with levonorgestrel implants in chinese... - PubMed - NCBI
Multicenter contraceptive efficacy trial of injectable testosterone undecanoate in Chinese men. - PubMed - NCBI

Granted, that was in Chinese men. Similar studies on caucasians found that testosterone was effective in around 80% of cases.
And sperm count and motility do drop for everyone once gonadotropin levels plunge, though some still maintain a viable sperm count.

Wow this is frustrating.... I feel like this is circular logic going on here. I make a statement, that statement is challenged, I provide support for my initial statement and then I am told that I am splitting hairs.

No angle here. Yes I am splitting hairs because that is what I am arguing. Never said that exogenous test was good for sperm production, simply that there are studies that show high levels of exogenous test support (maintain, preserve, conserve, retain, or whatever other synonym one would like) spermatogenesis. Not advocating anything other than the aforementioned position.

As for your comment about what they teach in college physiology. I took it as condescending because I have picked up on a "good ol boys" type feel around here and your following comment about me being "some random new member" reinforces that in my mind. Post count or join date is not a reflection of knowledge just for future reference.

Lastly, testosterone is, generally speaking, not regarded as an effective male contraceptive. It has and is being studied as such but is not currently used for said purpose.

Fine. I'm not disagreeing with you on that point.

No shit. "VET" is an earned title/rank here. It has nothing to do with post count.
And we likely have less "good ol' boy" stuff here than any other BBing/AAS site.

That doesn't mean that it is ineffective as such, but that there are dozens of other reasons why doctors won't just start handing out 300 mg/week of test to any guy who asks for it.

bold.

[PrettyPlease?]

bold.

As for VET status I was not discounting the knowledge of those who are VETS, only pointing out that just because someone does not have a title does it mean they are any less knowledgeable.

As for the last part in bold. I agree.

Moral of the story: 1000mg testosterone trumps clomid, HMG and HCG for fertility....

I'm living proof of this. ^^^^^

YES, or at least it means they have not been proven or acknowledged by those in charge as more or less knowledgeable. It's easy to cut and paste information or regurgitate something you have been told or heard but it's another thing to be able to actually use the information properly.

I consider myself quite knowledgeable about many things such as certain automotive subjects but I will be dammed if I am going to join a forum and start arguing with members or staff trying to prove myself. My parents taught me differently. When you are new somewhere you shut up, listen and learn even if you dont agree with everything until you are established and then start making suggestions or supporting your beliefs. Hopefully you will also be open minded enough to learn and accept some of their ideas but if not and you strongly disagree then maybe it's not a good place for you to try to fit in? Thats just my .02 and what Ive learned in life.
