2. Maintain Fertility. One small study showed exactly what would be expected: enclomiphene did a nice job of boosting fertility:
“Only men in the enclomiphene citrate group demonstrated increased LH and FSH. TT [total testosterone] decreased one month posttreatment to pretreatment values. Enclomiphene citrate elevated sperm counts in seven out of seven men at 3 months and six out of six men at 6 months with sperm concentrations in the 75â€“334â€‰Ã—â€‰106/mL range.” 
Advantages of Standard Testosterone Therapy Over Androxal
1. Natural Molecule. I have always felt that HRT was natural, because it is generally bioidentical (or darn close in the case of the injectible esters). Your body is used to it and even “craves” it if you are deficient. However, this is not the case with enclomiphene. No matter how you look at it, it’s an artificial, synthetic substance that may have some sort of unexpected impact. At this time, it is difficult to say just how much of an issue this is, since we have very few details on side effects and adverse events. But so far all SERMs have such a profile and I doubt that Androxal will be unique.
So the question becomes a matter of long term safety. My two cents – and I certainly don’t have a crystal ball any more than anyone else – is that well done HRT is very safe for the solid majority of men. It has done very well in the studies overall and, furthermore, has been around for decades now. Is Androxal something that can really be used for decades? I will only say that it is a pretty rare medication that goes into the plasma without touching anything except its target receptor and then exits (along with any metabolites) gracefully without affecting something along the way.

This may be shown by the side effect profile from the FDA Endpoint Classification Safety Study:
—7% and 3% of patients had an adverse event on 12.5 mg and 25 mg of daily Androxal, respectiviely. (In fairness, one could argue this is similar to testosterone and perhaps is due mostly due to issues related to increased testosterone levels.)
–3% and 7% of patients withdrew on daily dosages of 12.5 mg and 25 mg, respectively. The reasons for this are unknown, but perhaps it was due to unpleasant side effects?
2. Higher Testosterone Levels. In my case, I have found that I need about 600+ ng/dl for morning erections to return and I believe that morning erections are important generally for penile health. Notice that in the above study, the highest dosage of enclomiphene (25 mg) only achieved an average level of about 600 ng/dl. And in the fertility study mentioned above, the average testosterone was only about 550 ng/dl. Some men may want to go a bit higher and, short of taking off label amounts on enclomiphene, will not be able to do it.
This was echoed in a second study in 2015 that took 240 obese men with average testosterone of 200-230 ng/dl.  Fertility parameters were improved significantly, so that’s good of course. However, average testosterone levels in the enclomiphene group was only 450 ng/dl. Again, many men are going to feel just a little better with their testosterone at this level. See my page Normal Male Testosterone Levels for more information. (Some men will do great in the 400’s as the response to testosterone is highly variable.)
Interestingly enough, the phase 2 trails for FDA Approval produced even lower testosterone numbers. The only participants allowed in the study were men with total testosterone under 250 ng/dl. Men given 12.5 or 25 mg of Androxal daily raised their testosterone from an average of 217 and 210 ng/dl to 471 and 405 ng/dl, respectively. That 405 ng/dl is just not that impressive in my opinion and I think that the majority of hypogonadal men would not get significant relief from their low testosterone symptoms at that level. Perhaps physicians will give out 50 mg, though, and this will help. Time will tell.  What I am wondering is if the zuclomiphine isomer within Clomid is actually responsible for a significant portion of Clomid’s testosterone boosting powers?
3. Tight Control of Testosterone. As of this writing, we do not know what dosages of Androxal will be available. Patients have some ability to hit a target testosterone level via pill splitting, but injectible testosterones give much more granular control. A man can target with about a 100 ng/dl a target testosterone level.
4. No Loss of Efficacy. I saw a surprising number of men on Clomid, whose testosterone levels would slowly drop in the first few months. Will some men on enclomiphene experience the same thing? It’s difficult to say.
5. Tight Control of Estradiol. Many men on The Peak Testosterone Forum want tight control of their estradiol levels as well and argue that control of E2 is just as important as control of one’s T. Injectibles, especially more frequent subQ protocols, allow for this kind of estradiol management.
CONCLUSION: Assuming Androxal is reasonably priced, I think it is safe to say that it will be very popular particularly with younger men who wish to maintain their fertility and with any man who has a concern with pituitary function. However, I believe that many men will shy away from it, because it is synthetic and in many cases will not raise testosterone to normal youthful levels.
