Sperm donation is the process where a man provides his sperm to help individuals or couples conceive a child. Donors can be anonymous or known, and their sperm is collected through a medical procedure. The sperm is then screened for health issues and stored in a sperm bank for future use. People may choose sperm donation for various reasons, including infertility, same-sex couples wanting to start a family, or single individuals wishing to have children. The process is regulated to ensure safety and quality, and donors often undergo medical and psychological evaluations before participating.
