Testicular Volume and Spermatogenesis/Function - Swifto

[Fit N Fun]

Swifto,

Seems to me there is a slight flaw in the conclusion being drawn.

I had a vasectomy 6 months ago, this involves cutting then tying the sperm tubes off at the top of the testicles.

The surgeon said to me that after a while sperm production will cease because there is no where for the sperm to go.

I am on cycle just now and suffer from Atrophy, am trying Naltrexone rather than HCG to see what the effect will be on PCT.

Stopped taking the Naltrexone for a few days last week and sure enough my nuts shrunk well down, got them more or less back to full size after three days back on Naltrexone.

How do you explain changing testicular size in a vasectomised male?

Great read though!

My understanding is that having your vasa deferentia severed only prevents you from expelling sperm but does not effect your ability to get shutdown due to exogenous testosterone. The negative feedback loop is still in effect.

"After vasectomy, the testes remain in the scrotum where Leydig cells continue to produce testosterone and other male hormones that continue to be secreted into the blood stream."

And the naltrexone allows pulses of GnRH to occur as if no steroid hormones are present thus preventing spermogenise shutdown. In doing so allowing you to maintain full size of your nutz.

Agreed

"After vasectomy, the testes remain in the scrotum where Leydig cells continue to produce testosterone and other male hormones that continue to be secreted into the blood stream.".

Again agreed, as long as you are not on cycle

And the naltrexone allows pulses of GnRH to occur as if no steroid hormones are present thus preventing spermogenise shutdown. In doing so allowing you to maintain full size of your nutz.

According to my surgeon, after a vasectomy, Spermatogenesis ceases because there is no movement of sperm from the testes, this function is lost for as long as the vasa deferentia exit path is blocked.

I have found how to get Naltrexone to reliably inflate my testes, it remains to be seen whether this will translate into a minimal PCT.

However the conclusion in the article that " Testicular volume had the strongest positive correlation with sperm density"seems to me to lack credibility since in my system there is no longer any sperm production.

It appears to me that there may be other factors at play like the parts of your testes that produce Testosterone. We are all very aware of the positive effects of HCG in the production of Testosterone and also the effect that HCG has on the Volume of your testes.

Testosterone production seems to me to be a much more likely reason that your testes are inflated.

Interesting indeed let us know how your transition into pct is.

Interesting indeed let us know how your transition into pct is.

I have a thread on my investigation into whether Naltrexone will keep the HPTA functioning while on cycle removing the need for PCT.

I think its pretty obvious that this theory does not apply (size/spermatogenisis) if you've had a vasectomy.

Naltrexone may have kept or stimulated GnRH, thus LH/FSH stimulating the testes, which would explain the size of your testes when your using Nal.

Glad you agree on that

If the theory does not apply to vasectomised males, is there any reason to assume that it applies to non vasectomised males?
