Btw, it took decades for post SSRI syndrome to be taken serious, last year it was finally officialy recognized and SSRI's are a lot longer on the market.

The Steroidogenesis Inhibitor Finasteride Reduces the Response to Both Stressful and Rewarding Stimuli.
Abstract
Finasteride (FIN) is the prototypical inhibitor of steroid 5?-reductase (5?R), the enzyme that catalyzes the rate-limiting step of the conversion of progesterone and testosterone into their main neuroactive metabolites. FIN is clinically approved for the treatment of benign prostatic hyperplasia and male baldness; while often well-tolerated, FIN has also been shown to cause or exacerbate psychological problems in vulnerable subjects. Evidence on the psychological effects of FIN, however, remains controversial, in view of inconsistent clinical reports. Here, we tested the effects of FIN in a battery of tests aimed at capturing complementary aspects of mood regulation and stress reactivity in rats. FIN reduced exploratory, incentive, prosocial, and risk-taking behavior; furthermore, it decreased stress coping, as revealed by increased immobility in the forced-swim test (FST). This last effect was also observed in female and orchiectomized male rats, suggesting that the mechanism of action of FIN does not primarily reflect changes in gonadal steroids. The effects of FIN on FST responses were associated with a dramatic decrease in corticotropin release hormone (CRH) mRNA and adrenocorticotropic hormone (ACTH) levels. These results suggest that FIN impairs stress reactivity and reduces behavioral activation and impulsive behavior by altering the function of the hypothalamus-pituitary-adrenal (HPA) axis.

Fina has a strong effect on neurosteroid activity in the brain:
Neurosteroids like 3?-androstanediol (derived from DHT) and allopregnanolone (derived from progesterone) activate the GABAA receptor in the brain; because finasteride prevents the formation of neurosteroids, it functions as a neurosteroidogenesis inhibitor and may contribute to a reduction of GABAA activity. Reduction of GABAA receptor activation by these neurosteroids has been implicated in depression, anxiety, and sexual dysfunction.[61][62][63]
Incidence of type 2 diabetes mellitus in men receiving steroid 5α-reductase inhibitors: population based cohort study
Fina raises chance of diabetes
The risk of type 2 diabetes was increased by approximately 30% over 11 years in men with benign prostatic hyperplasia who received one of the 5?-reductase inhibitors on the market, finasteride or dutasteride compared with tamsulosin
Additional monitoring might be required for men starting these drugs, particularly in those with other risk factors for type 2 diabetes.

Abstract
BACKGROUND:
Combination therapy with 5 alpha-reductase inhibitor (5-ARI) and alpha-blocker can be considered as a gold standard intervention for medical management of lower urinary tract symptoms related to benign prostatic hyperplasia (LUTS/BPH). On the other hand, 5-ARI monotherapy and in particular Finasteride alone is currently getting focus of attention especially due to lack of systematic reviews investigating efficacy outcomes and/or adverse events associated.
OBJECTIVES:
Aim of the present critical review was to analyze current knowledge of clinical efficacy and incidence of adverse events associated with 5-ARI treatment for LUTS/BPH.
MATERIALS AND METHODS:
A systematic review of clinical trials of the literature of the past 20 years was performed using database from PubMed, Cochrane Collaboration and Embase. A total of 8821 patients were included in this study and inclusion criteria for studies selection were: data from randomized clinical trials (RCTs) focusing their attention on the clinical role of Finasteride monotherapy for symptomatic BPH. Parameters of research included prostate specific antigen (PSA), prostate volume (PV), International Prostate Symptom Score (IPPS), postvoid residual urine (PVR), voiding symptoms of IPSS (voiding IPSS), maximum urinary flow rate (Qmax), and adverse events (AEs).
RESULTS:
Overall 12 original articles were included and critically evaluated. Sample sizes of patient actively treated with finasteride varied from 13 to 1524 cases analyzed in a single study. Follow-up after treatments ranged from 3 to 54 months. The effect of finasteride in reducing prostate volume (PV) was moderate (standardized mean difference (SMD) effect between 0.5 to 0.8 for all trials evaluable) while the effect on IPSS score and Qmax was considered significant (SMD in the 0.2 to 0.5 variation range). No severe AEs and/or psychiatric disorders were retrieved among the studies.
Sexual health dysfunctions were significantly influenced by finasteride therapy when compared with placebo treated patients.
CONCLUSIONS:
Although significant clinical benefits of finasteride monotherapy were demonstrated, the effective size of the available reports included in the analysis is limited. Additional head-to-head studies would be needed to re-evaluate clinical efficacy and safety of 5-ARI in combination or not with alpha blockers.

Anyway, you can get pfs after a couple of pills or 5-10 years, I've read more than enough about this to know you are never safe if you take fina or duta.
