I just want to point out that ethinyl estradiol is NOT the active form of estrogen naturally occurring in humans. It is the first orally active semisynthetic steroidal estrogen, and was first synthesized in 1938. (http://en.wikipedia.org/wiki/Ethinyl_estradiol)
It is a very potent form of synthetic estrogen, but is extremely nasty stuff, at least in terms of its side effects. It should be avoided at all cost. Among other deleterious side effects, this is from a long-term study of MTF transexuals published in 2011:
Quote:Current, but not past ethinyl estradiol use was associated with an independent threefold increased risk of cardiovascular death.

If a physician is still prescribing this for transition, you would be well advised to find another doctor.
Thanks for that but I said nothing about it being naturally occuring. It is active nonetheless, I was just pointing out that estrogen sensitivity can cause quick reactions. Also interestingly enough, the main active compound in PM is pharmacollogically very similar to ethinyl estradiol in particular.
It's still used in most MTFs here in Australia and I know several who have used it for a few years and is still the standard pregnancy pill.. also the standard dosage is 30ug/day, not 100ug/day as mentioned in the baseline of the study, which is probably why it is considered safe.
We actually don't have Oestradiol in tablet form here in Queensland, only a weak patch form, so there really isn't much choice if we want to have medical oversight.
"The increased mortality in
MtF in the 25–39 years of age group (SMR 4.47; 95% CI:
4.04–4.92) was mainly due to the relatively high
numbers of suicides (in six), drugs-related death
(in four), and death due to AIDS (in 13 subjects)."
"In this large cohort with a median follow-up of more
than 18 years, we observed in MtF transsexual subjects
a 51% relatively increased mortality rate compared
with the general male population, mainly due to
increased rates of death from suicide, illicit drugs,
AIDS, cardiovascular disease, and unknown causes."
Which has very little to do with the estrogen prescribed, most legit TS patient will find an improvement in mental health on any estrogen, like I did. Also doesn't clearly differentiate on anti-androgen use in the baseline which is the real mental health concern while mentioning the higher suicide rates of Cypro users.. Cypro is known to cause suicidal tendencies while Spiro is far safer and the standard anti-androgen of choice.
It is well known that any estrogen can contribute to DVT risk, might be higher in the case of ethinyl estradiol. Maintaining good cardiovascular health is an important part of any HRT regime as any good doctor will tell you. But for healthy young subjects, the risk is negligible with ethinyl estradiol, especially if being monitored by a medical practitioner.
