My opinion is guys like us need to have our testosterone and estrogen levels monitored continually: an anti-aromatase drug like Arimidex should bring estrogen levels right down. Clomid is a SERM (won't lower overall estrogen levels) and I've never read anyone use it for gynecomastia related issues: the SERMS that occupy the estrogen receptors in breast tissue are tamoxifen and raloxifine...again, I'm not a doctor, but it seems to me that the SERM you're taking could be a contributor to the problem.
I will take the advice and have estrogen checked again. However, if it is high, I don't have any good options. Stopping Clomid means my testosterone will go back to low levels. Taking an estrogen blocker brings other health risks and side effects, and it is a lifelong process. Either way, my gyno started before my low T problem (at least before low T was discovered), and if that is what triggered the gyno, there appears to be nothing I can do.
Low T causes gyno?
Normal T causes gyno?
High T causes gyno?
Sheesh
I think (and I'm just trying to help so take whatever you want from this) that T level is a factor but you can't draw any conclusions from T level alone because it isn't the direct cause - aromatization of that testosterone into estrogen is the direct cause. Both the level of aromatization (amount of aromatase enzyme your body produces) and the testosterone level (more testosterone to aromatize) are factors and different combinations can lead to high estrogen: low T with lots of aromatase enzyme could equal high estrogen...high T with normal amounts of aromatase could equal high estrogen...high T with low aromatase could equal low estrogen...etc. And Tiger Paws is right: one guy could have high estrogen and never have a gynecomastia issue...another guy could have lower estrogen than the first guy and have a gynecomastia issue. Sounds confusing but it really isn't: you and I are the guys that, if we have high estrogen, we're going to have gynecomastia issues (and we might be in the majority because I see lots of guys with chest growth). If our estrogen level is high, it's because we're aromatizing a lot of testosterone into estrogen. That could be because we produce more aromatase enzyme or because we have a lot of testosterone to aromatize (the latter is me: testosterone level 781 and estrogen 220).
You do have options if your estrogen level is high. You are using a SERM right now which has no effect on global estrogen level. All that does is block estrogen receptors in tissues. And as far as I know, it isn't as effective as Tamoxifen in blocking estrogen receptors in breast tissue (don't think it's used at all in female breast cancer treatment, but I could be wrong). Clomid does raise testosterone levels by blocking the receptors that can get occupied by estrogen to cause the body to think that testosterone is high when it is not. Tamoxifen does the same thing and it seems to be preferred by drug using bodybuilders (and frankly, I trust their collective knowledge more than doctors who don't care about the issue).
You also have the option of using an aromatase inhibitor: this blocks the production of the aromatase enzyme (no aromatase enzyme, no estrogen). Drug using bodybuilders don't use it post drug use to restart their testosterone levels because a total crash in global estrogen isn't desirable (they do use aromatase inhibitors while using drugs to keep estrogen levels in check). But that wouldn't be your purpose for using it: your purpose for using it would be to get your estrogen level into the normal range. Unfortunately, the only way to know how a dosage effects your estrogen level is to have blood tests for estrogen level frequently...I'm using anastrozole (arimidex) at .5 mg every other day and I'll have an estrogen only blood test done in two months: if estrogen isn't low-normal, I'll up the dosage (most likely, it's going to be too low and I'm going to have to reduce the dosage...but we'll see what happens). If you think taking an anti-estrogen for an extended period is a health issue, I'd submit that high estrogen levels pose health risks too.
Lastly, I don't believe that if you get estrogen from high to normal that you'd be stuck on anti-aromatase drugs for the rest of your life. I think hormone levels can get out of whack, need to be brought back normal, and can be maintained (and should be monitored) going forward. All kinds of things can cause hormones to get out of whack: stress, lack of sleep, training (or not training), environmental factors, etc. which means all kinds of things can be done to maintain normal hormone levels once they are achieved.
This is really the last thing: surgery. If you get a bunch of the breast tissue/gland removed through surgery, you may be less susceptible to estrogen induced gynecomastia going forward. There are bodybuilders who developed gynecomastia, had the surgery, and then continued their drug use without recurrence. I think that this is where having an excellent surgeon comes in: there's a balance they have to contend with, which is taking too much gland material and you having cavity deformation or not taking enough and, if you get into high estrogen again (or never get it under control), you've got a lump and growth again.
I think you've got tons of options.
