***“On the 7th day of abstinence, however, a clear peak of serum testosterone appeared, reaching 145.7% of the baseline ( P < 0.01). No regular fluctuation was observed following continuous abstinence after the peak.”
A research on the relationship between ejaculation and serum testosterone level in men. - PubMed - NCBI
***Even though ejaculations seemingly have no significant effects on serum testosterone levels, they can (at least according to rodent studies) alter the body’s ability to utilize testosterone. It has been seen that after multiple ejaculations a sharp decline in androgen receptors takes place inside the hypothalamus, and not only that, but a sharp increase in estrogen receptors follows as well. One rodent study also found out that 1 or 2 ejaculations in short span of time increased androgen receptor activity in the body, while 4 or more ejaculations caused a significant drop in the activity of AR, suggesting that ejaculating yourself to “sexual exhaustion” might lower your body’s ability to utilize androgens.
Ejaculation and Testosterone Levels: Masturbation Lowers T?
***Studies have shown if you masturbate more than twice in a day, there becomes a decline in androgen receptors in your brain. These are what allows your body to use testosterone by binding to it – with less of these, the less your body can use and lower your active testosterone levels will be. [7]
And to make matters worse it’s been seen to make estrogen levels increase. [8] While your androgen receptors are on the decline, estrogen receptors are on the rise, meaning they’re binding to more of the female hormone in your body and increasing your risk of lower testosterone.

Does Masturbating Lower Testosterone? - TestoFuel Blog
***Today, there is also a growing number of evidence that links testosterone levels with the number of times you ejaculate in a single day. This is evidenced by changes observed in your number of androgen receptors or receptors that allow you to utilize testosterone throughout your body. Hence with lower androgen receptors, you will essentially also have lower active testosterone levels.
According to a study conducted by the Universidad Veracruzana in Mexico, one to two ejaculations for a short period of time can increase androgen receptor activity. However, when ejaculations are done four or more times during a short period of time, there is a significant reduction in androgen activity. Specifically, it was observed that androgen receptors returned to its baseline level after the fourth ejaculation. (study)
This finding seems to be supported by another study done by the Centro de Investigación y Estudios Avanzados and Instituto Nacional de Ciencias Médicas y Nutrición 'Salvador Zubirán' in Mexico. Their experiment revealed that multiple ejaculations resulted in a significant decline in androgen receptors. (study)
At the same time, a study conducted by CINVESTAV in Mexico found that while androgen receptors are decreased after multiple ejaculations, there is also a significant increase in estrogen receptors. (study)
Is There a Link Between Masturbation and Testosterone?
***Dopamine is a major factor. Drugs and activities whichc change the regulation of dopamine will alter libido. Dopamine agonists (pramiprexole), dopamine reuptake inhibitors (wellbutrin, cocaine, methamphetamine) will all cause increases in reward seeking behavior including but not limited to libido. Dopamine blockers such as antipsychotics are often considered libido killers.
Dopamine is counter-regulated by prolactin which is released after male ejaculation, so increases in prolactin cause dopamine and libido to drastically fall off. The other name for dopamine is prolactin inhibiting hormone, or PIH. Males who are able to ejaculate multiple times in a row with no refractory period tend to have a reduced production of or response to prolactin.
Testosterone is a huge factor in libido for men and women. Testosterone acts as a neuromodulator and potentiates dopamineric activation of the sex drive.
ELI5: What causes libido, and why does it vary so much between people? : explainlikeimfive
***It not only helps regulate testosterone production in men, but also helps to regulate immune functions, salt and water balances, metabolic functions, endocrine system, brain and behavior, and growth and development. Prolactin is what tells your body that it’s satisfied after sex, and lets the arousal mechanisms (aka dopamine) know they can settle down for a bit.
...
Because higher levels of prolactin are found in fathers of young children and in expectant fathers, as compared to un-mated males, according to a large-scale study in the Phillipines, behavioral endocrinologists have theorized that a modest rise in prolactin helps prepare men for the task of fatherhood. It quiets the sex drive, they figure, and along with oxytocin—with its weird reputation for being both the “cuddle” hormone as well as a byproduct of stress—helps dads of young children bond to and empathize with their offspring.
…
Elevated levels prolactin in the blood signals the gonads to make less testosterone (hypogonadism).
…
Sometimes levels also go up during periods of stress, even briefly.
...
It can be helpful to look at prolactin levels next to testosterone levels, because ongoing high prolactin secretion will signal the body to lower testosterone production.

this is what 'YOU' can achieve after 'X' amount of days! : NoFap
- 5 minutes - heart rate returns to normal.
- 2-3 days - guilt and shame seems to decrease.
- 7 days - brain fog lifts.
- 14 days - prolactin starts to drop.
- 14 - 21 days - due to drop in prolactin, dopamine sensitivity increases, you can start to enjoy the little things in life again, no longer emotionally numb, energy levels start to increase big time, confidence also increases.
- 30 days - cravings and flashbacks noticeably reduce.
- 30-60 days - PIED symptoms disappear or improve. Erections become rock solid, unless you're PIED symptoms are severe. Confidence keeps rising
- 42 days - ΔFosB (DeltaFosB) that has accumulated around the nucleus accumbens starts to remove itself. This makes it possible for the neurons in the porn-addicted pathways to now start to slowly break up over time without use.
- 90 days - considered a full reboot for most people, however people with severe PIED will need longer. Confidence still rising
- 120 - 150 days - symptoms of severe PIED disappear or improve.

they have defined 'live'. now you define 'live'.
that is true. but the study isn't comparing us with eunuchs of that time, but normal people of that time with eunuchs of that time. the assumption is that you can translate that information to now because you've determined the variable. the other variables are accounting for the difference in longevity between the normal people of that time and of now. the increased longevity of eunuchs was several hundredfold, if i remember correctly, with more centenarians than normal at the time.

Sure, they explain why living to 70 is really impressive.

The lifespan of Korean eunuchs
Although many studies have shown that there are trade-offs between longevity and reproduction, whether such trade-offs exist in humans has been a matt…www.sciencedirect.com
It just gives credibility to the fact that being eunuch is not just being castrated, but living a different life altogether. In animals you can see what happens to eunuchs if they live a normal life, and in the wild the outcomes would be even worse for eunuchs.
they don't explain that either. again, they simply discovered that korean eunuchs lived longer than their intact counterparts, and suggest rightly that testosterone is a key player. granted, that's their hypothesis. but the records themselves are a given. sure, the records could be false, but that's a different issue.
It seems like your trying to gaslight yourself. Any intense sport will increase testosterone, why the fixation on weightlifting? Do you think a martial art or football will not have the same effect, lmao. They just have lesser studies done as hormonal profiles in those sports are hard to measure and not as easy as doing a couple weightlifting exercises.
if you read the article you would know that the researchers account for that. plenty of eunuchs had wives and children. they even suggest their bond was pretty strong. that's were other hormones come into play.
where is the gaslighting happening? i don't see it.
Stress reduces testosterone synthesis but doesn't zero it out, and most of the "reduced" synthesis is basically conversion into other hormones (mainly estrogen).
Castrated dogs are mostly pets, so if we compare castrated pets to non-castrated pets it would be an interesting study. Even better if we do this in nature, as hormones prepare you for your surroundings.
Go off the internet for a while man. Low stimulus rest for 1 week and come back. I don't think 90% of the gymgoers does anything you stated there, except for losing weight which is always stressful, but then again how many gymgoers are absolutely shredded? You can absolutely increase your health by doing weightlifting.
It truly seems to me that you are trying to convince yourself (not us, not discussing it with us) that doing sports and optimizing your hormones (WHICH is synonymous with increasing health) is a bad thing, and that you should artificially keep testosterone low by neglecting your bodies needs (sports, health, stuff like eating meat and eggs which will help testosterone).
my point exactly, not castrated to non-castrated pets, but castrated to non-castrated street dogs.
you make a lot of unwarranted assumptions about my personal life. you must think yourself clairvoyant or something. i love exercise and i eat what you say i don't eat. but what does my personal life have to do with that study? focus: not me, but the study.
This is the character assumption Ainaga, not what I said about taking a break.
Taking a break from stimulation does not mean you are too much on the computer, it means you are too stimulated and that the computer is also a source of stimulation.
Peak autism, even though you will call it being a snowflake or being easily triggered. You don't "approach" people to debate, but start with:
It's like going to a person to debate something, but namecalling them and expecting an honest discussion. Take a break, seriously. It's like your telling your bias from the getgo: Homo's are weird but lets talk about homosexuality.
X is more manly than Y because he has his balls, yes. This is like saying, a trained female fighter can beat some women, but a trained male fighter can beat all women. X has no balls but can be more manly than some man, but a manly man that has balls is more manly than all eunuchs. Of course with hormones influencing all behaviors, it makes logical sense.
Research also shows thyroid and a good metabolism ages you faster and that seed oils are good for you. Doesn't mean ***t you know? Common sense? If testosterone is stress protective, and it can also aromitize into a stressor (estrogen), then it can be either very healthy or very unhealthy. "Research" is only "research" if it truly tests one thing, and does not have a lot of factors unaccounted for, and does not have an agenda behind it.
