PAIS here with the classic serum levels - high T, very high LH and FSH and a plethora of physical characteristics. Also confirmed DES exposure when mum was pregnant with me. I never had a chance. 
PAIS is a comparatively rare condition though. If you're DES exposed, then the chances are that it's the sole source of your problems, especially since I've been told it can result in a very similar presentation to grade 3 PAIS.
Unfortunately, there aren't many studies of hormonal abnormalities in DES sons. However, I've obtained copies of 3 studies carried out in the 1970s, looking at DES sons from the Dieckmann cohort (made up of children from a study carried out in the 1950s, that showed that DES was completely ineffective at preventing miscarriages). These people were all exposed to the standard "Smith and Smith" treatment regimen, which is what most DES mothers worldwide were given. I talked about one of these 3 studies in this post a few days ago:
http://www.gendersupport.org/forums/index.php/topic,84224.msg1607617.html#msg1607617All 3 studies show much the same thing, the main unusual finding (aside from high rates of genital abnormalities) being that the DES sons produced significantly less sperm (both the volume of ejaculate and the number of cells per ml) than the control group. In the paper I linked in that post, it says the production of sperm cells was effectively halved. One point I was trying to make in that post is that if only half as many sperm cells are being produced on average, then production of that other thing the testicles produce - testosterone - has probably been halved too. That would explain why I, and quite a lot of the people who've replied to that thread, and DES-exposed people I've chatted to on facebook etc, all tend to have eunuchoid proportions and other symptoms of below normal male T levels.
In that paper and the other two, they've compared hormone levels between the DES sons group and the control group. The DES sons have, on average, slightly lower total T and slightly higher LH and FSH than the control group, but the differences aren't very large. However, they've only measured total T, there are no measurement for free T, SHBG or estradiol (E2).
I think what happens to people like us is that our bodies try to produce a hormonal state intermediate between male and female, and that results in lowered T production and elevated E2 production (perhaps by ramping up production of the aromatase enzyme). One effect of elevated E2 is that it increases the amount of SHBG, and the excess SHBG binds up nearly all the availalable T, creating a large reservoir of inactive T and driving down free T to very low levels. The problems caused by high E2 and SHBG get talked about a lot in the hypogonadism forums I subscribe to, because it makes it look like you've got fairly decent T levels on the blood work, however nearly all of it is inactive, and the high E2 tends to further reduce the effectiveness of what little free T remains, so you continue experiencing symptoms of hypogonadism despite having what look like good T levels on paper. Free T, not total T, is the important thing when it comes to biological effects.
I've recently been talking to two DES sons, both of whom have gender dysphoria but aren't currently in a position to transition, both of whom have symptoms of hypogonadism and were refused treatment by their doctors because their T levels were "normal". One had a total T of about 500 ng/dl and the other 350ng/dl (which is actually well below normal), however the free T in both cases was very low - 60pg/ml and 71pg/ml, due to their SHBG being quite high. In neither case was their E2 measured, however one of them has quite pronounced gynecomastica, so I guess his E2 at least is well above normal male.
From a study aimed at determining what T levels should be in normal, healthy men:
http://press.endocrine.org/doi/full/10.1210/jc.2010-3012"In a reference sample of 456 men, mean (sd), median (quartile), and 2.5th percentile values were 723.8 (221.1), 698.7 (296.5), and 348.3 ng/dl for TT and 141. 8 (45.0), 134.0 (60.0), and 70.0 pg/ml for FT, respectively. In all three samples, men with low TT and FT were more likely to have slow walking speed, difficulty climbing stairs, or frailty and diabetes than those with normal levels. In EMAS, men with low TT and FT were more likely to report sexual symptoms than men with normal levels. Men with low TT and FT were more likely to have at least one of the following: sexual symptoms (EMAS only), physical dysfunction, or diabetes."
I read this as saying that "normal" (within 1 standard deviation of the mean) total T in men ranges from 500 to 950 ng/dl, and free T 100 to 195 pg/ml. Both of the people I've been chatting to have free T levels that came in the bottom 2.5 percent of that study, the people with "slow walking speed, difficulty climbing stairs, frailty and diabetes". Yet they've both been refused treatment by their doctors. I don't know what doctors are basing these decisions on, but it certainly isn't science or concerns about patient welfare.
What all this shows is that most doctors don't have the first clue when it comes to hormones. Also, that there are probably a lot of DES-exposed individuals out there who are being wrongly diagnosed with other complaints by their doctors, for problems that are actually caused by DES. Maybe you're one of them?
