Dal mio punto di vista i sides sessuali (non ritenzione idrica..), come il calo della libido e l'incapacità di mantenere l'erezione sono impudabili allo scarso livello di dht e non all'aumentata conversione del testo in estradiolo.
Il dht è direttamente coinvolto fisiologicamente nella virilità.
Qui uno studio molto interessante giapponese: (Posto solo l'abstract)

Abstract
Aim: To investigate the ultrastructural changes of penile corpus cavernosum and tunica albuginea in rats treated with castration or finasteride. Methods: Eighteen male Sprague-Dawley rats of nine weeks old were randomly divided into three groups with 6 rats each. Group A served as the control, Group B was castrated and Group C, treated with finasteride. Four weeks later, rats were anesthetized and blood samples obtained for the determination of serum testosterone (T) and dihydrotestosterone (DHT) levels; penile tissues were taken for scanning electron microscopy. Results: The T, free T and DHT levels in Group B and the DHT level in Group C were significantly lower than those in Group A (P<0.05). The tunica albuginea was significantly thinner in Group B than that in Group A (P<0.05), but there was no significant difference between Group C and Group A (P>0.05). Elastic fibers in the tunica albuginea of Group A were very rich and arranged regularly and undulatedly, but in Group B, most of the elastic fibers were replaced by collagenous fibers. In Group C, the tunica albuginea was mainly composed of thick and irregular-arranged collagenous fibers. In Group A, there were abundant smooth muscle fibers in the trabeculae of corpus cavernosum, but they were much less in Group C and scarce or even disappeared in Group B. In Groups B and C, the diminished/disappeared smooth muscle fibers were replaced by irregularly arranged collagenous fibers. Conclusion: In rats, androgen is essential for maintaining the normal structure of penile tunica albuginea and corpus carvenosum.
Lo studio presente indica ke negli animali maschi con bassi livelli di dht indotti da finasteride possiedono fibrosi nel corpo cavernoso, fibre di collagene irregolarmente organizzate, e diminuzione delle fibre muscolari lisce nell'organo sessuale.
Rispetto al guppo castrato privo di testosterone i fenomeni sono meno accentuati.
I risultati indicano ke l'androgeno è cmq essenziale per il mantenimento delle normali strutture della tonaca albuginea del pene.
Mi piacerebbe credere il contrario.. ma temo non sia così.
Bisognerebbe ke qualcuno ke ha avuto questo tipo di sides, provasse a riprendere fina o duta con un antiaromatasi e verificare la presenza dei sides, ma io personalmente sono scettico.
