A Discussion on the Relationship Between Gender Identity And Prenatal Exposure to Diethylstilbestrol (DES) in 46XY Individuals 

   Questions

 

 

 

It's time to put what we have learned about DES together and ask a few questions. On this page I summarize the things DES can do and then look at some dosages used in cohort studies. The results are quite startling. I then ask some pertinent questions.

DES can affect development in numerous ways.

 

[1] Inhibits androgen receptor binding16), so the effects of testosterone on the cell are diminished. "At high dosage, on the other hand, DES produced an opposite effect, inducing hypospadias and inhibiting prostate growth and AR binding activity."

 

[2] Lower the over all testosterone levels 27): "DES inhibits luteinizing hormone secretion by the pituitary, there by inhibiting testosterone secretion.167)  " In analogy with animal studies showing strong activational effects of androgens on nuclear AR-ir, the present data suggest that nuclear AR-ir in the human MBC is dependent on the presence or absence of circulating levels of androgen."

 

[3] DES is a potent synthetic estrogen, so it can bind to cells estrogen receptors. It also interferes with Mullerian Duct Regression 125).

 

[4] Transgenerational effects are also being investigated 124).

 

[5] Toxic : Capable of causing injury or death. In fact a recent paper designed to downplay the psychosexual effects of DES inadvertently indicates that the death rate to males exposed in utero is 2.5  that of the control group "Briefly, 1% of the poten-tially eligible women (exposed or unexposed) and 3% of the men (5% exposed, 2% unexposed) had died before the combined study was implemented ".83)  "Diethylstilbestrol can cause fetal toxicity when given to pregnant women" 27).

 

Normally the mother's estrogen, which passes to the fetus via the placenta, binds with proteins, making it inert, and thus protecting the fetus from its effects. However, these proteins do not bind effectively to DES. If they did, then none of the physiological effects DES is known to cause would occur.


Ample proof exists that prenatal DES exposure affects the physiological development of the human fetus (CDC , very cautious about what they say). Given this and given present research on the effects of hormonal exposure on the physiological and neurological development on the non human fetus, is it irrational to conclude that DES also has the potential to affect the neurological development of a human fetus? Was the dosage negligible?



If we roughly equate the potency of DES to Premarin (see dosing for prostate cancer: conjugated estrogen's versus diethylstilbestrol). During the course of a pregnancy, expectant mothers were given up to 11 times the total amount a transitioning m-to-f transsexual would take during the same period of time (5mg/day).  To start lets look at a table provided by the NIH on Cohort study dosages 240) .

 

From - the web site of the Law Offices of Aaron M. Levine & Associates 10):
"The drug manufacturers who jumped on the DES bandwagon either never made the computations or didn't care, but the recommended dosage of DES given to pregnant women, shown in Slide B, was the equivalent of the estrogenic effect of 55,666 birth control pills."

 

Slide B of the above link is a Smith & Smith regimen, enlarging the slide so that it is easily legible and then adding up the recommended dosage for a pregnant mother between week 7 to week 35 equals 11.725 grams of DES. (Dosage varied from week to week but the lowest dosage was 5mg/day) As we will see below only 3mg/day is required to chemically castrate an adult male.


Using typical (US) hormone regimens for male to female transsexuals 20) as a comparison:
In addition to anti-androgens and progesterone one regimen includes about 5mg of Premarin a day. During the same period of time (35-6=29 weeks = 203 days) a transitioning adult male would ingest about 1.015 grams of Premarin.

 

If we compare the dosage to that given adult males for the treatment of prostate cancer (see below), we see that only 3mg a day of DES is required to chemically castrate an adult  male.

 

Suggested Dose Options for the use of DES in the treatment of prostate cancer in adult males: "There is an abundance of information indicating that 5 mg is too high a dose given the side effects and that lower doses have similar efficacy against prostate cancer with a lower toxic profile.  The 5mg/day dose results in castrate levels of testosterone as does the 3mg/day dose.  A dose of 1mg/day is not sufficient to reduce serum testosterone to castrate levels in all patients. However, the 1mg/day and 3mg/day doses have equivalent effects on prostate cancer (6)."

 



IF
genetic males with cloacal extrophy reassigned to female at birth and raised as female have male gender identities similar to people with 5-alpha reductase,
and if
people who are genetically male with CAIS have feminine gender identities,
and if
the gender identities of people genetically male with PAIS and partial gonadal dysgenesis range from masculine to feminine and some switch genders as they mature,
and if
at the cellular level prenatal DES exposure (higher dosage) equals a combination of chemically induced PAIS (milder forms) and chemically induced partial gonadal dysgenesis,
then ...........

 



IF
In the mouse and rat you can do prenatal or neonatal treatment with estrogens or androgens to feminize or masculinize behavior,
and if
the behavior of a female rhesus monkey can be masculinized by prenatal exposure to androgens,
and if
researchers are sure that prenatal hormone exposure affects the sexual dimorphic development of the mammalian brain,
then ...........



IF
Universities and colleges teach courses which discuss the possible effects of prenatal hormone exposure on the development of the brain and thus changes in behavior,
and if
the infamous Dr. John Money, who is the founder of the “psychosexually neutral theory,” is now admitting that prenatal hormone exposure  may play a part in the formation of gender identity,
then ...........


 

What’s wrong with this picture?
