Dejo aqui unos cuantos estudios que dicen lo que siempre te he dicho y no paras de no creerte. Estamos hablando de una minoria, como el prospecto dice.
http://jnci.oxfordjournals.org/content/99/13/1025.long (n=17,313) Overview of sexual side effects from the PCPT trial. "The effect of finasteride on sexual functioning is minimal for most men"
http://www.ncbi.nlm.nih.gov/pubmed/8881946 (n=14,772) Observational cohort study. "Impotence or ejaculatory failure, decreased libido and gynaecomastia in a small proportion of patients were associated with the use of finasteride. This drug is acceptably safe when used in accordance with the current prescribing information."
http://www.ncbi.nlm.nih.gov/pubmed/12477383 (n=8,820) Overview of BPH Trials. "Significantly more sexual dysfunction, impotence, ejaculation disorder and decreased libido occurred with finasteride at 12 months; the NNH for any sexual dysfunction at 12 months was 14"
http://www.ncbi.nlm.nih.gov/pubmed/20956649 (n=3,927) Review of efficacy and safety for treating hair loss. "Moderate-quality evidence suggests that daily use of oral finasteride increases hair count and improves patient and investigator assessment of hair appearance, while increasing the risk of sexual dysfunction."
http://www.ncbi.nlm.nih.gov/pubmed/9610579 (n=3,270) Long-term safety study of finasteride in use for BPH.
http://www.ncbi.nlm.nih.gov/pubmed/21980923 (n=3,177) Study on 3,177 japanese men for hair loss. "Adverse reactions occured in 0.7% (23/3,177) of men; seven men discontinued treatment based on risk-benefit considerations. No specific safety problems associated with long-term use were observed."
http://www.ncbi.nlm.nih.gov/pubmed/12639651 (n=3,040) PLESS placebo controlled safety study of finasteride for treating BPH. "Compared with placebo, men treated with finasteride experienced new drug-related sexual AEs with an increased incidence only during the first year of therapy."
http://www.ncbi.nlm.nih.gov/pubmed/10197842 (n=895) 5-year efficacy and safety study of finasteride. "Finasteride was well tolerated, with no significant increase in the prevalence of sexual adverse events over time."
http://www.ncbi.nlm.nih.gov/pubmed/12670567 (n=725) 6-year placebo controlled study on finasteride. "no increase in the prevalence of drug-related adverse events over time."
http://www.ncbi.nlm.nih.gov/pubmed/11763381 (n=472) Evaluation of sexual side effects in 1mg finasteride. "The sexual and erectile function of subjects taking finasteride does not significantly differ from that of age-matched controls. This is consistent with the experience of many dermatologists who do not see sexual or erectile dysfunction in patients taking Propecia."
http://www.ncbi.nlm.nih.gov/pubmed/12695131 (n=424) 2-year efficacy and safety of 1mg finasteride. "Treatment with finasteride 1 mg was generally well tolerated."
http://www.ncbi.nlm.nih.gov/pubmed/23067029 (n=378) Safety assessment of fin vs dut. "The incidence of erectile dysfunction, ejaculatory dysfunction and decreased libido resulting in discontinuation from therapy for finasteride was (2.1%, 1.8%, 1.4% respectively."
http://www.ncbi.nlm.nih.gov/pubmed/15262698 (n=186) Evaluation of sexual function for 1mg finasteride. "Our results support the clinical impression that sexual side effects are actually much less common than reported in clinical trials. The sexual function of all patients remained stable during treatment with 1 mg of finasteride." (This is less than 200 participants, but I included it since it was more relevant due to it being conducted on younger men)
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2840927/ (n=N/A) Finasteride and it's impact on sexual function and prostate cancer. (This is a retrospective analysis, but I wanted to include it because it analyzed some of the studies I posted and also gives some great information)
Ahora coge tu y ponme el mismo numero de estudios que diga justo lo contrario. Estoy esperando.
