Did some quick reading on the negative effects of very low prolactin as I wasn't very informed, and it apparently such a state can induce a low 5AR type state by reducing the output of adrenal androgens (DHEA for example), and can result in low DHT, which I'm guessing is where a majority of the effectiveness of this treatment comes from.
So, again, another promising treatment is going to come down to being highly anti-androgenic and whether or not you can tolerate it. I'm just going to assume that the more effective a treatment is, the more intense the side effects are likely to be. If you're comfortable with a low androgen state, I'm not sure whats keeping someone from stacking finasteride/dutasteride with ru58841, which I can't imagine wouldn't provide some results for most.
Semen quality and serum testosterone were studied in six men with hypoprolactinemia (less than or equal to 6 ng/ml) and in normoprolactinemic controls. The incidence of hypoprolactinemia in 92 men attending an infertility clinic was 7.5%. Males with hypoprolactinemia showed in high percentage of...

Our findings demonstrate that, in subjects consulting for sexual dysfunction, PRL in the lowest quartile levels are associated with MetS and arteriogenic ED, as well as with PE and anxiety symptoms. Further studies are advisable in order to confirm our preliminary results in different populations.
