The rat ovaries are composed of a network of blood vessels, ducts, and many other things and genuinely look like miniature brains. Micro-computed tomography lets us image the female gonad at a high resolution and peer through its curious structures in a 3D reconstruction. The ovaries are responsible for the production of sex hormones estrogen and progesterone. These hormones contribute to uterine function by modulating electrical and mechanical activity in the uterus throughout the hormonal cycle.Adjusting colours, viewing angles, and transparency can create fabulous scenes. In this colourful display, the oviduct looks like a playful sprite dancing under the foliage produced by the ovary and around the uterine horn trunk.
