How do pregnancy tests work? - Tien Nguyen - YouTube
Over-the-counter pregnancy tests give potentially life-changing results with a pretty high rate of accuracy. But how do they work? Tien Nguyen explains how each test performs a scientifically rigorous, multi-stage experiment that goes from start to finish in the time that it’ll take you to watch this video.

The Intersex Roadshow: The Phalloclitoris: Anatomy and Ideology
What we are not usually taught is that that all humans start out in the womb with the same initial genital structure. This is certainly studied by embryologists, if not familiar to the general public, and I will give a basic tour in this post. I'm not going to use the language embryologists do, though, because I find it very odd. They refer to the initial human form as the "indifferent stage," often say that the genitals "appear female," yet term the sensitive end of the genital structure the "phallus." The truth is that we all start out appearing neither female nor male, and we certainly don't start out with penises. We all start out intersex. Our initial form (which some of us retain) is pictured at the top of this post. Let's examine it.

Human Genital Development
We all begin life with genitals that have four basic external elements. At the top is the part numbered 1 on my drawing: the sensitive end of the phalloclitoris, which can differentiate into the head of the penis or clitoris. In the center is structure 2: an inset membrane that can widen or can seal as the fetus develops. It will form the urethra, and the vagina, if any. Around it is structure 3, which is capable of differentiation into either a phallic shaft, or clitoral body and labia minora. And at the outside is the fourth part, the labioscrotal swellings, which can develop into labia majora or a scrotum.

There is a lot of variation in how each of the four basic parts of the genitalia develop from person to person in all of us. For example, we acknowledge with a lot of rib-elbowing the variation in penile size. Variation in the size and shape of genitalia, and in other parts of the body, is part of human diversity.
