You have several choices if you have leftover embryos after a successful in-vitro fertilisation procedure. Some individuals opt to keep their embryos indefinitely frozen, whereas others may decide to discard their unused embryos once their family is complete. The surplus embryos may also be donated for scientific research or to another family, such as other people or couples who are experiencing infertility.
The field of assisted reproduction is constantly growing, and embryos donated to scientific research allow us to find out more about fertility and reproductive medicine.
