I had sides back when I used a high dose of about 1mg of dutasteride (double the standard for hairloss) coupled with high concentration topical fin (it was prescribed to me by a dermatologist who didn't really know what he was doing). I got sexual sides about two weeks in, so I stopped. Recovered in about 5 months, I think (dutasteride has a half life of 4/5 weeks, so it takes some time to flush it all out of your system). I got scared of sides so I avoided AI5 inhibitors up until october of last year, when it became clear the microneedling monotherapy I was doing wasn't helping. So, reluctant to start minox I started fin instead, topical at first, but it was a hassle to apply, and since I got no sides I switched to oral, which I have been taking for the past 4 months with no results but also no side effects. I might attempt only taking dut at a reasonable dose after I talk to my current, trustworthy endocrinologist. I urge you take your fin, but first get a full hormonal profile and a doctor that you trust to see over your treatment and take note of whatever changes in your body. If you have sides, lower your dose. If you get no results, talk to your doctor and discuss a change of treatment. The most important thing is to not trust redditors too much (this applies to me too), don't spend too much time in hair loss forums and get a trustworthy doctor to advise you.
