Here in the comments I see many reasons why this episode was good, or even great, and only a few why it was bad. I was very good entertained by this episode, and I felt from the very beginning (well, that interracial dating joke had to be, hadn't it ?) the sense of Trek as it should be. The ending may be unexpected, but for a show like this, it was simply brave and completely in line of what had to be said to this topic.
And the topic was a very sensitive one. It has multiple layers under the surface, it's, amongst others, about parents making the right decisions for their children. There are a lot of people who suffered from gender change in their early childhood, simply because doctors didn't realize their gender. But that's only one aspect. Another is the question, if one-dimensional thinking, especially when "life-changing decisions" are pending, can be harmful (though indeed well meant).
Everyone should ask him/herself, if in the situation of the baby, how should it be - would it have been better for him/her to be changed or to be let untouched, risking a childhood of being an outcast ? One could talk about this for hours, finding endless other related topics and arguments, therefore I consider this episode as inspiring and thought-provoking, furthermore unpredictable and unconventional (yes too many people think of too many conventions that this show should fit into).
And I am thankful for not being lectured by the morals of this episode but entertained by its thoughtful approach.
And, btw, I was NOT confused about Klyden and the 75 year-rate of born females. I thought it is to be expected that a society would make up this low rate, while in fact it is much higher.
