Research: Do nighttime erections and baldness correlate?

All I know is you can have erection multi times during sleep, other factors can affect it like the time you sleep, how deep is your sleep, your diet, your overall health, age,.... I did a quick search and the normal duration time seems to vary: some sites say 20-30 minutes, some say 5-10 minutes.

I see that your theory has a close relation to sleep. I did an experiment on myself: sleeping at 10 pm and waking up at 5 - 6 am every day for 2 months. The idea is to get enough sleep and sleep at the right circadian rhythm. While it makes me healthier, I see very little to no improvement in hair loss.

Don't discourage thought, IMO we need different thinking if we want to find a cure. If everyone thinks the same, it is likely we get the same result. If you want to look for ways to modifier your sleep, you can get some ideas from Matthew Walker, he has focused on the impact of sleep on human health.

Sleep couldn't have any noticeable effect on hair loss unless you had severe sleep deprivation and telogen effluvium. Environmental factors have little to do with hair loss. It's about 80% genetic. Smoking has been shown to slightly increase the severity and onset of hair loss, likely through oxidative stress and promoting ePRL. It's not the degree of change you'd notice outside of a study.

At that time, here is my thinking, in short:
- Good sleep reduces stress, and inflammation, two things that might relate to hair loss.
- Chinese medicine is adamant about circadian rhythm, they believe there is the optimal time for sleep or things that we do.
- Sleep is recovery time. Good sleep can correct your body function(like thyroid). If you have bad sleep for a long time, maybe a body's function becomes faulty, and with certain genetic people, it leads to hair loss.

Well, as I said, I see little to no improvement in hair loss, so I was wrong. What I learned about this experiment is if you find a cure, good sleep will faster the process. It makes me healthier and improves hair quality a bit in 2 months.


In environmental factors, why you are so sure about it having little to do with hair loss? Isn't it proved that environmental factors can impact gene expression?

Because it's been demonstrated in twins. Environment affects gene expression, but you have those genes. https://www.sciencedirect.com/science/article/pii/S0022202X15362837

Sorry if I misunderstand that article, but isn't it only imply that there is an association between certain genes and Androgenetic Alopecia?

We all agree there is a big genetic factor in Androgenetic Alopecia, but I don't believe that is as high as 80%. There is a twin study that show those people can have different baldness rate.

The first one clearly has a slower baldness rate. What did he do to make the difference? and more important question is: If he did some "right" thing to halt his baldness, did he do it enough? If we can identify that thing, can we make it more effective so that can minimize the baldness rate?

Two studies put the heritability of Androgenetic Alopecia at at least 80%. It is more heritable than height. This is the study I was referring to when I mentioned smoking. It shows only minor differences. Environmental factors can slow the rate of onset by a couple years at most. That's not very significant. It's like how malnutrition or smoking can stunt your growth by a few inches but it can't make you a dwarf. If you have the genes to go bald you WILL go bald no matter what you do without medical intervention
