Does that meet with your [snip] satisfaction?
As far as homosexuality goes there isn't much mentioned. In Reproductive Consequences of Developmental Phytoestrogen Exposure
this is about as
close as it gets.
This study of over 7000 children enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC) found an association between early life
soy exposure (starting prior to age 4 months) and masculinized play behavior in girls at age 42 months. There were no measurable effects in boys, and
the effects on girls were attenuated by 57 months of age.
But referring to the actual study, we see this:
Our study suggests that early-life exposure to soy products may subtly reduce female-typical play behaviors in girls at 42 months of age. Given
the low prevalence of soy use in this study sample, associations between soy exposure and PSAI score were imprecise, and results should be interpreted
The associations observed here were modest, and the mean PSAI score for all exposure groups was still within the range of normal
behavior for each sex.
So there was no difference seen in boys and girls didn't play with dolls quite as much. Interesting contrast to what the first article stated; "less
female-typical play" as opposed to "masculinized play". Seems the first article might have a bit of a bias.
Prenatal sex hormone effects on child and adult sex-typed behavior: methods and findings
makes no mention of phytoestrogen but it does say
Overall, studies of females with exposure to atypical hormones because of maternal treatment are consistent with studies in clinical
conditions, showing behavioral effects of prenatal exposure to androgens, but not to estrogen.
Gay brains structured like those of opposite sex
But as Savic herself acknowledges, the study can't say whether the brain differences are inherited, or result from abnormally high or low exposure
in the womb to sex hormones such as testosterone.
You list a couple external quotes about primary sexual characteristics having nothing to do with homosexuality. But from your wikipedia link:
Since research suggests that hormones alone do not act on sexual orientation and differentiation of the brain, the search for other factors that
act upon sexual orientation have led genes such as the SRY and ZRY to be implicated.
I'm not sure why you posted the next quote:
Hormones, Sexual Dimorphism, and the Brain—A Primer
Sex is determined by two chromosomes: men have one X chromosome and one Y chromosome, while women have
two X chromosomes. The Y chromosome contains the SRY gene, which triggers a flood of androgens (the group of hormones that includes
testosterone) sometime between six and twelve weeks of gestation, guiding the development of the penis and testes. But this fetal testosterone bath
also makes its mark on the brain’s architecture, resulting in sexually dimorphic brain circuits.
It quite clearly specifies
testosterone as the influence for male development. Nothing about homosexuality there. Nothing about phytoestrogen. Nothing about estrogen.
You actually did list one source which indicated there may be a link between phytoestrogen exposure and "masculinized play behavior" in girls. But it
seems that interpretation is not consistent with findings of the cited study. It also seems that androgens have a greater effect on prenatal
development than estrogen. That would make sense since the placenta is pretty well flooded with estrogen anyway.
On a bit more personal note, my father received estrogen therapy for prostate cancer. He did not become homosexual but his breasts did enlarge. He
didn't like that.
You are...off topic. Of course, so am I.
