I volunteered at the local Aids council and one of the areas covered in my group was trans gendered people. One thing I learned was that this therapy is not lightly treated, before any medical intervention there has to be extensive psychological evaluation, more so than any other intervention.
This is not an isolated case, the headline is “Lesbian Parents” suggesting a hidden agenda. The parents have had the child under psychological care for years as quoted in several articles “At age seven, after threatening genital mutilation on himself, psychiatrists diagnosed Thomas with gender identity disorder. By the age of eight, he began transitioning.” The treating specialist would have spent a lot of time with the child to confirm that the emotions were that of the child and not the Lesbian agenda, (what ever that is) The doctor's that disagree with the treatment are not the child's treating doctors, they are just giving an opinion. You can't just get these blockers over the counter .they are regulated in their dispensation.
Regarding the hidden agenda most lesbians I know that have children including boys are great parents and accepting of their children and studies have shown that children with homosexual parents are well adjusted.
Here is a link to a more unbiased story of a similar child http://www.npr.org/templates/story/story.php?storyId=90273278
Some specialists disagree with the diagnosis in this story.
The botom line is that by giving blockers the child has time for the brain to mature some before going on to transitioning.
A quote from the 14yo sister in the story above
"In terms of how Violet thinks about hormone blockers, her older sister, Melina, says that the problem of puberty is very much on her mind. "She's getting hair in some places and stuff and ... every day she says that she feels a little bit more manly. Which is really hard for her."
Melina, who is 14, says she sometimes thinks about what it would be like if she woke up every day to a body that was slowing turning male. If she were growing in ways that felt alien and frightening.
"To go through the process of the gender that you're really not ... that must be the most scariest most disgusting thing ... I can't even imagine what that's like," she says.”
