IVF and ICSI

Daily injections from day 2 of the cycle stimulate several follicles, monitored by scans. A trigger injection matures the eggs, which are collected 34–36 hours later. In ICSI a single sperm is injected into each egg, and embryos grow in the laboratory for up to five days.

• Egg collection is done under light sedation
• The trigger injection must be taken at the exact time given
• Usually one embryo is transferred
• The full cycle takes about three to four weeks
