This is not a scientific paper. It is a "narrative review", which is another way of saying "editorial". It superficially looks like science, but doesn't do any of the methods, controls or (correct) statistics that you would expect in a legitimate meta-analysis. Do not take it seriously.
The "dedication" at the top should clue readers into what is going on -- it's not even trying particularly hard to look legitimate -- but alas.

True, and, I'd posit that there are often better and safer alternatives that would be similarly or more beneficial with less potential for harmful side effects.
I have several anecdotes from my own life. When I was ~18 the doctor proposed to give me jaw surgery to fix my overbite by extending my lower jaw. I asked him what the reasons for this were and he said it was mainly cosmetic. I thought this was not a good enough reason for surgery - which while often safe does also often have harmful side effects - I now know way too many people who had surgery complications that often took a long time for them to become aware of. I think I feel better about myself now for having made that choice than I imagine I would if I had a better jaw line.
It's true that some people are going to have a story where they see the cosmetic medical intervention as having been beneficial for their mental wellbeing. I'd still suggest that in many such cases there might have been other ways to get a better outcome. It's for each of us to decide.
Still, burden of proof of the safety of a drug should be on the company profiting from it.

The paper mentions that finasteride passes through the blood-brain barrier and affects the conversion of progesterone to allopregnanolone, where low levels of allopregnanolone are associated with depression. Together with the correlational evidence for depression and suicidality, this presents a reasonable picture for concern.
Since there is a known central activity, it also raises the question -- in fact the article explicitly mentions it -- of whether a brain-sparing analogue of finasteride might not show the same side effects.
The apparent connection to "masculinity" or "feminization" may be a red herring. Excessive concern about "sex" effects in biological systems kind of reminds me of the alchemical theory of the four elements. It's not a great way to analyze the complicated effects of medicines.

Endocrinology is a lot more complicated than you're giving it credit for. DHT blockers don't necessarily lower testosterone levels; they can actually increase it (although even then, the mechanism isn't as direct as you might think).
It's neither established nor a given that any side effects of finasteride have anything to do with effects on testosterone or hormone levels at all. A lot of people make that assumption, and there's reason to suspect there's truth to that hypothesis, but it's completely possible it's an unknown side effect of the drug, and there hasn't been enough study into the mechanism to understand it (in part because the side effects are relatively rare and weakly established).

I'm shocked that this wasn't widely known in the US. Reports from trans people, way back in the 1940s, show clear links between sex hormones and depression: a priori, one would assume such a relationship would exist here. The article appears to allege a cover-up:
> It is difficult to imagine what data could justify hiding in a drug safety review.
I've been sceptical of any direct relationship between "post-finasteride syndrome" and sexual function, but I've never doubted the direct effect on mental health of suppressing dihydrotestosterone in cis men. (Even if the pharmacological effects end shortly after cessation, which I suspect, a sudden and unexplained strong feeling of constant wrongness can be traumatic.) The part I find interesting is that most men seem to be just fine with taking finasteride, even orally.

When I got it prescribed (in AU), my doctor told me he had many patients taking it with no side effects, and he also pointed out that the 1mg I was taking was much smaller than the 5mg some took for prostate enlargement. I also did some reading and never noted any links to depression. It just doesn't seem to always come up.
I think many men would also (naively) be happy to risk depression when confronted with impending hair loss. Ironically, maybe more happy chemicals are what's actually needed so we can feel like losing our hair is not the end of the world.

Fin blocks the conversion of T to DHT, that rarely causes lower blood serum testosterone levels and can possibly even increase them depending on what else you've got going on hormonally.
groovy2shoes 1 hours ago [-]
indeed, finasteride raised my T levels slightly, from 18 ng/dL to 30 ng/dL. the same enzyme that converts T to DHT (5α reductase) can also to convert progesterone to DHT via the backdoor pathway, but i reckon that would have a very small effect for most cis men (where normal progesterone levels range from 0.0-0.5 ng/mL, compared to 2.0-24.0 ng/mL in cis women during the luteal phase, and much higher during pregnancy).
a sudden hormonal change can absolutely cause changes to mood and libido, but with finasteride these seem to be rare and generally mild. i would expect them to lessen or even disappear after some time of continued treatment. i wonder how often finasteride is discontinued before the body even has a chance to adjust to the new hormone levels. the claims that the side effects persist after discontinuation are particularly dubious, and they remind me of castration anxiety.

Not kidding: What about suicides prevented from not going bald? To paint a fair image, this study should also compare suicide prevalence for bald people.

Results: Compared with the controls, an increased risk of suicide attempts was observed in patients with AA, with an adjusted hazard ratio of 6.28 (95% confidence interval, 4.47-8.81). Suicide risk remained significantly elevated in AA patients when stratified by underlying psychiatric disorders. The mean age of initial suicidal behaviors was also lower in patients with AA.
Conclusions: Patients with AA had a significantly higher incidence of suicidal attempts than controls, regardless of concurrent psychiatric illness. Further studies are needed to elucidate the pathophysiology of the association between AA and suicidality. In addition, dermatologists should be aware of the increased suicidality of patients with AA.

It's also possible that people taking Finasteride might be a more potent selection of people that are distressed about hair loss, and are therefore more likely to exhibit depression, etc. As in, if people with androgenetic alopecia are more likely to be depressed, people who take finasteride may be a sampling of those people who are distressed enough to seek and maintain treatments.

Finasteride every year changes millions of lives globally, I take finasteride, and it’s the sole reason i have my hair.
Idk about you, but i know 10s of different friends who also went through hairloss and were struggling to stop it, who went through severe depression, loss of confidence, suicidal tendencies in extreme cases.
Just because you saw a study that X drug causes side effects/harms in 1-0.1% of patients, doesnt mean the med should be taken off sale especially for a drug as important as finasteride.
It’s easy for someone to say it’s just a cosmetic drug until they go through the full extent of social, mental, and even physical damage, hairloss at a young age causes.
I and almost everyone who takes finasteride take it knowing the risk of a whole range of side effects , often far more severe then just increasing risk of depression. like risk of reduction in fertility, libido in some patients often struggling with obesity.
Obesity creates a whole range of problems too, should we start prosecuting creators of tasty food too ? , fin 1mg is one of the most impactful drugs sold globally both under brand names and generic cheap drugs (i take a generic one) that is life changing for almost a quarter or more of men depending on the country who face male pattern baldness and its related issues.
More studies certainly should be done in link of depression and suicide in some patient cases, but bringing out the pitchfork like luddites and asking to prosecute executives and scientists for a non-opiod, non-addictive, drug that’s been used safely for decades across generations, and saved families thousands of dollars (including mine) in snake oil salesman products that claim to treat hairloss but dont.

Dutasteride is not a stronger version of finasteride. It's a more effective DHT blocker, but it works differently.
The side effects are also different and not easy to predict. Some people have terrible side effects from finasteride and none from dutasteride. Some people have the opposite. And some people can tolerate either one. We don't have a way at the moment to reliably predict which one will work better or be better tolerated for a given individual.
Anyway, I'm glad it has worked for you, and I also would not want to prosecute people who've created a medication that's one of the most effective and well-tolerated around.

If anything finasteride has improved my mental health. I've taken it for ~7 years with no negative side effects, and I'm certain it's the only reason I still have hair
It seems clear to me that anything which has depression as a side effect has an increased risk of suicide as well and the only remaining truth to find is the degree.
The executives and scientists should both be prosecuted.
Idk about you, but i know 10s of different friends who also went through hairloss and were struggling to stop it, who went through severe depression, loss of confidence, suicidal tendencies in extreme cases.
Just because you saw a study that X drug causes side effects/harms in 1-0.1% of patients, doesnt mean the med should be taken off sale especially for a drug as important as finasteride.
It’s easy for someone to say it’s just a cosmetic drug until they go through the full extent of social, mental, and even physical damage, hairloss at a young age causes.
I and almost everyone who takes finasteride take it knowing the risk of a whole range of side effects , often far more severe then just increasing risk of depression. like risk of reduction in fertility, libido in some patients often struggling with obesity.
Obesity creates a whole range of problems too, should we start prosecuting creators of tasty food too ? , fin 1mg is one of the most impactful drugs sold globally both under brand names and generic cheap drugs (i take a generic one) that is life changing for almost a quarter or more of men depending on the country who face male pattern baldness and its related issues.
More studies certainly should be done in link of depression and suicide in some patient cases, but bringing out the pitchfork like luddites and asking to prosecute executives and scientists for a non-opiod, non-addictive, drug that’s been used safely for decades across generations, and saved families thousands of dollars (including mine) in snake oil salesman products that claim to treat hairloss but dont. They should get awards, not pitchforks.
I have receding hairline and I am not touching fin with a 10-foot pole. It's basically chemical castration.
My whole family on both sides is bald bald. Without it I would have been bald bald in my early 20s.
I knew there were risks of hormone disruption/mood swings/etc but I still prefer it over being bald. I took a calculated risk and I'm thankful that the drug exists. Please don't prosecute the people that gave me the only real, working treatment for my baldness.
Dutasteride is not a stronger version of finasteride. It's a more effective DHT blocker, but it works differently.
The side effects are also different and not easy to predict. Some people have terrible side effects from finasteride and none from dutasteride. Some people have the opposite. And some people can tolerate either one. We don't have a way at the moment to reliably predict which one will work better or be better tolerated for a given individual.
Anyway, I'm glad it has worked for you, and I also would not want to prosecute people who've created a medication that's one of the most effective and well-tolerated around.
For what? Many drugs have depression as a possible side effect, but that doesn’t mean they should be pulled from the market and executives prosecuted for simply the possibility of depression.
Negative reactions to drugs are always a possibility. Weighing the risks and tradeoffs and monitoring patients is important. This is why drugs like this are not OTC.
If there was some indication that the pharmaceutical company knew of and concealed evidence that finasteride caused depression/suicidality, then there could be grounds for criminal prosecution. But a non-consensus view in hindsight that a drug might increase depression looks more like a losing civil liability claim.
