Egg or sperm donation involves individuals providing their eggs or sperm to help others conceive a child. Donors can be anonymous or known to the recipient, and they undergo medical screening to ensure their health and genetic suitability. This process is often used by couples facing infertility or same-sex couples wishing to start a family. The donated eggs are typically retrieved from the donor through a minor surgical procedure, while sperm can be collected through a simple process. Once collected, the eggs and sperm can be used in in vitro fertilization (IVF) or other assisted reproductive technologies to create embryos for implantation.
