Side effects of saw palmetto topical?

[pick]

Hello,

I was prescribed Androanagen (Minoxidil + Aminexil + Saw Palmetto) topical (http://www.ebay.com/itm/Androanagen-...-/151625623990) and Androanagen tablets (http://ww2.justanswer.com/uploads/ax..._picture_2.png)

After 4 days of using them today I felt a sudden low libido. I am usually really horny but today I felt saint like. My penis felt a little less hard while masturbating (I forced myself to check) and it was just not as "smooth" as before. Semen was also slightly more watery.

It could just be a hard day at work that's made me tired, but is there a possibility of the above medications causing this?

I am planning to skip the tablets and just apply the solution topically. Will that still be an issue?

Please help me guys. This is really taking a toll on my already troubled mental health.

Thank you
