While this is very impressive it does not show a correlation between hair loss. Please note that the main cause of hair loss is not the below mentioned hormones as they are present in most males but the fact that there is an imbalance and usually related to nutritional deficencies. If you resolve the deficencies then the hair withstands the increase in normal hormonal activity post sex and masterbation.
I wrote my thoughts about this on another thread so I will copy some from there and add some new tgoughts as well..
According to abstinence studies after 7 days without ejaculation there's a big spike in Testosterone levels, but it goes back down the next day. After 3 weeks without ejaculation, T levels are slightly higher than baseline on the chart, and didn't reduce as much from Fapping, I don't know about DHT though.
this is why at one point, I was on a schedule to ejaculate every 6 days, Lol.
So, I personally believe that long term abstinence will hurt you in the end. Your body won't stop making T, and sex drive is not the only thing your body uses T for. Ifyour deprive it of orgasm and sexualthoughts long enough, eventually yourbody will probably use your T in otherways.
Look up pics of the Dali llama, He's supposed to be Abstinent. (I guess it'spossible that he's Jacking it secretly, butthat is hard to imagine to be true)
Sometimes his buzz cut is short enough to see his hairline is not complete.
Now with that said, After orgasm, Prolactin levels are elevated for about an hour. There are Prolactin receptors in scalp, andprolactin induces Catagen phase..
at least according to studies on pubmed. but I dont know if I can even believe those studies since Antydhtor had amazing regrowth while taking high doses of cypro, which is known to increase prolactin.. so maybe the anagen extending effects of estrogen is stronger than the catagen promoting effects of prolactin?
I don't know, if the one hour above baseline hasmuch effect but I imagine Jacking offEveryday, would. then that would be higherthan baseline prolactin for an houreveryday. However, Masturbation is not theSame as Sex, the prolactin release iscorrelated with the quality of the orgasm, and after sex there is 4x the level than after Masturbation.
however, prolactin is both good and bad in some ways, it reduces T and DHT and T/DHT also causecatagen/aptosis. A number of experimentaldata indicate that hyperprolactinemiainhibits the activity of 5-alpha-reductase. Prolactin also inhibits GnRH which reducesthe release of Lutenizing hormone, ( LHincreases T production) BUT I have readthat it upregulates Lutenizing Receptors inLeydig Cells( cells in testis that make T) So,it could decrease LH but increase sensitivityto LH,, and may decrease T short ter butincrease it long term...
Also, I could see abstinence from pornagraphy being beneficial maybe. And I think the way you masturbate matters to. Ifyou are spending Hours searching p*rnlooking for that perfect video, increasingyour Testosterone and then having anorgasm not as powerful as sex or powerfulenough prolactin release to counteract thatT inducing p*rn viewing. (There may be some conflictng information on if p*rnviewing increases T, I read one study somewhere that said serum T levels rose 90 minutes after p*rn viewing Withoutfapping)
