"The most striking results are related to the sperm count. The average value of sperm density (count/ml) is approximately 2 times (factor of 1.93) lower in the DES-exposed group...The average quality score is in the pathologic range for the DES-exposed group (6.9) and normal for the control group (1.4.)...Ejaculate volumes of less than 1.5 ml were observed in 10 out of 39 subjects (26%) in the DES-exposed group versus 0 out of 25 in the control group...The results show that only 14 of 39 (36%) of the DES-exposed group can be classified as normal whereas the control group shows 18 of 25 (72%) with normal scores...11 of 39 (28%) of the DES-exposed group received scores greater than 10, classified as "severely pathologic", whereas none of the 25 subjects in the control group received this score."
If sperm counts are on average halved, then production of that other thing the testicles make - testosterone - has probably been halved too. That would explain why I, and seemingly a high percentage of DES sons, have developed a "eunuchoid" body structure and other signs of undervirilization.
I've made a couple of posts on another thread expanding on what I've said there, so I thought I'd transfer the gist of them to this one, in case anyone's interested and to keep everything in the one place.
In Bibbo 1977 (where the above quote came from) and a couple of other papers I've seen looking at the same cohort of DES sons, they're briefly mentioned the results of blood tests of the DES sons vs controls. The total T is a bit lower on average, but the results don't look very different from the control group. However, the blood work they've published is incomplete. All they've shown are the total testosterone, LH and FSH. They haven't shown two key measurements: sex hormone binding globulin (SHBG), and free testosterone.
Free T, not total T, is the important thing as far as the biological effects of T are concerned. SHBG is important because, if it's high, then it binds up almost all of the T in your body and you can end up with what looks like a quite respectable T level based on total T, even though free T is well below normal. From reading what people have said in some hypogonadism forums I belong to, a common problem they encounter through badly administed T replacement is that their estradiol (E2) goes high, and this in turn causes their SHBG to go high. They end up with what looks like quite a respectable total T level, but their free T remains low, and they continue experiencing the symptoms of hypogonadism.
The ideal SHBG level for males is apparently around 20 ng/dl. In the blood work I've had done, and in the blood work of 2 DES sons I've chatted to about this, our SHBG levels have all been around 40 ng/dl. None of us know our E2 levels (doctors hardly ever request E2 in blood work for males), however I've got gynecomastica and so has at least one of the DES sons I've been chatting to. As most of you probably know, breast development is a good indication of higher than normal male E2!
What I think is going on is that, in biologically male people who've been feminised by prenatal exposure to drugs such as DES, our bodies try to generate a hormonal state in between male and female. They do this by increasing E2 production to above normal male (perhaps by ramping up expression of the aromatase enzyme), and reducing T production to about half normal male. As a side effect, the lowered T production means the testicles don't grow to full size and only produce about half as much sperm as normal. Meanwhile, the elevated E2 causes SHBG to rise well above what it would otherwise have been, and all this excess SHBG results in a large reservoir of inactive T, which means the total T doesn't look too bad even though both the production and consumption of T are only about half of normal.
All this is speculation of course, since none of us had our hormone levels tested in our 20s, and the published research hasn't included measurements of SHBG or free T. However it would tie in with my developing a eunuchoid body structure and other signs of low T, something which (judging by the comments on this thread and what I've seen people saying on facebook), happens a lot amongst DES exposed individuals!
The two DES sons I've been chatting to (both of whom have gender dysphoria, but for personal reasons aren't currently in a position to transition), both 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. I don't have their blood work written down, but from memory the one with total T 500 had SHBG 45 and free T of 60 pg/ml, the one with total T 350 had SHBG about 35 and free T of 71 pg/ml. These are extremely low values for free T.
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. If your total T is below 348 or free T below 70 pg/ml you're in the bottom 2.5 percent of the range, the people with "slow walking speed, difficulty climbing stairs, frailty and diabetes". Both of the people I've been chatting to have free T levels at or below 70 pg/ml, and problems with low enegy, depression, brain fog, ED etc, typical symptoms of hypogonadism. One has already developed type 2 diabetes which has become insulin dependent. 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 based on science or improving the health of their patients!
Going on my experiences, your body seems to be able to handle having abnormally low hormone levels OK while you're young, but as you get older the hormone imbalance gets worse and worse, and you start developing all sorts of health problems as a result in middle age. Incidentally, going on female HRT protects you from all this, because the estradiol you take as part of your HRT replaces the missing T.
Those two haven't yet started on any kind of HRT. Unfortunately I don't have any blood work from prior to taking hormones, but here's two sets of blood work I had done last year, by which time I'd been on fertility meds for about 3 years.
In this first one,

I'd been taking my usual combination of fertility meds (clomid and HCG) and progesterone cream. Everything in that test looked OK, not just that part of the panel but everything else too (apart from my cholesterol being slightly elevated, but not enough to warrant taking action).
Using a separate online calculator, my calculated value for free T is 128 pg/ml, which is just a little bit below the average for free T (141.8 pg/ml) in that study of healthy men I linked to earlier. I felt pretty good the day of that test, alive, full of energy and with no aches or pains.
In this second test,

(15.2 nmol/L = 438 ng/dl)
I'd stopped taking fertility meds for 5 days. You can see how the total T has fallen by about a third, and the LH and FSH readings have basically collapsed. The FSH is flagged as being below the lower limit of the lab range (and probably the LH reading would have been too, except there would still have been some HCG in my system, which shows up as LH unless they do a special test to exclude it). That second test is basically what secondary hypogonadism looks like - LH and FSH are low, and so is total T.
Using the online calculator, my free T would have been 86 pg/ml, so it had fallen below the "normal" (100 - 195pg/ml) range for healthy men, but was still higher than what the 2 people I've been chatting to are having to put up with. I'd felt rough the day before the test and quite unwell on the morning the blood was drawn (I was actually supposed to wait a further 2 days before having it done, but by that stage had decided enough was enough, why make myself sick for a further 2 days).
Unfortunately, the doctor I saw following that second blood test (who is the senior doctor at that practice) turned out to be a total bastard. He refused to refer me on to an endocrinologist, or for a DEXA scan to assess my bone density, or for an MRI scan to see whether I have a brain injury that might explain my being hypogonadal. This is despite the fact that, apart from the blood work, I look kind of intersexed, and a physical examination would show that I have eunuchoid proportions and other symptoms of hypogonadism. I got a very strong impression that, if it had been up to him, I wouldn't have even had the tests I've had done, and I was quite lucky that I saw a junior doctor there on my first couple of visits who ordered them for me. So I'm not sure what was going on there, perhaps the practice has to bear some of the costs for those tests, or maybe he was just one of those doctors who turn eugenicist when dealing with trans and intersex folk. Either way, he's basically trying to condemn me to a slow and horrible death, and it hasn't done a lot to restore my faith in medicine. It makes me wonder how many other people like me are out there with endocrine systems damaged by drugs such as DES, whose health is now failing as a result, and are being lied to and denied treatment by their doctors.
