    Here's a summary of an interesting article in this week's (9/29/84)
SCIENCE NEWS, with the somewhat sensational headline "Hormone markers for
homosexuality?"

    It seems that a group of researchers at SUNY Stony Brook "have found
what they believe may prove to be a physical correlate to homosexual
behavior."  The study "suggests that biological markers for sexual orientation
may exist."  The work "does not address the question of what causes
homosexuality."  The study was reported in the September 28 SCIENCE.
    "There's a good possibility there's a biological element involved with
sexual orientation, but it's a long way from saying that it's determined
biologically," says one of the authors of the report.

    The researchers studied 17 straight men, 14 gay men, and 12 straight
women, and monitored the responses to injections of estrogen.  In women,
this causes a slight drop and then a sharp rise in the amount of
luteinizing hormone (LH) in the body.  This occurs naturally as part of a
woman's monthly hormonal cycle.

    The results:  four days after the injection, the women's levels of LH were
200 percent of their baseline values, the heterosexual men averaged 88%, and
the homosexual men averaged 138% of baseline.  "Although not all the homosexual
men studied showed an enhanced response of LH to estrogen compared to the
heterosexul men, significantly more did."  [Note that this means that the
average levels in those WITH the enhanced response were HIGHER than 138%.]

    The SCIENCE NEWS article then goes on to mention some responses to this
report, and theorizing by, other members of the research community.

    A total population of 43 subjects seems a little low for any statistical
significance, and one is puzzled by the omission of homosexual women from the
study, but it's interesting food for thought, anyway.
