LessWrong user links egg freezing to family planning decisions On 26 August, LessWrong user boba_girl wrote a note following the June Reproductive Frontiers conference, linking egg and embryo freezing to family‑size planning. She views oocyte cryopreservation, embryo creation, and polygenic screening as interconnected decisions about timing, partner choice, and the number of possible births. She starts from her personal situation: she wants children but is still looking for a partner. “I think that once I find a partner I will also try to freeze some embryos,” she writes. Until then, storing eggs buys her time to choose a partner. Embryos are created after a partner appears, and their number helps the family envision how many birth attempts they could plan. Thus, her reasoning links the choice between eggs and embryos to two goals: preserving freedom to choose a partner and anticipating the possible embryo stock. On the consumer market for polygenic screening, the procedure looks like a series of IVF cycles, genetic testing, and selection. boba_girl starts this chain earlier, asking what options can be preserved before embryos exist. Polygenic ranking compares the resulting embryos using statistical forecasts of disease risk and certain complex traits derived from genetic data. The number of viable embryos determines both the number of comparison options for that ranking and the number of potential birth attempts. In her note, reproductive technology enters family planning step‑by‑step: first freeze eggs, then decide with a partner about embryos, and finally choose among those that are obtained. 🔗 Read original →
