Of related interest. And to put the complexity of fertility into perspective. A recent study in fruit flies demonstrated the signalling, transcription and synthesis of a protein called "Hindsight". Which triggers the breakdown and rupture of follicle cells. Thereby releasing a single ovum to be fertilized. An amazing result is that the proteins humans produce for priming their follicles to release an egg. Can be transplanted into fruit flies. With an analogous priming of fruit fly follicles for ovulation. Suggesting that genes regulating fertility and reproduction are conserved across the full spectrum of Animal Kingdom phyla. Zinc-finger transcription factor Hindsight regulates ovulation competency of Drosophila follicles https://elifesciences.org/articles/29887 https://elifesciences.org/articles/29887
