Sperm donation is a procedure in which a man donates semen — the fluid released during ejaculation — to help an individual or a couple conceive a baby.
Donated sperm can be injected into a woman's reproductive organs (intrauterine insemination) or used to fertilize mature eggs in a lab (in vitro fertilization). The use of donated sperm is known as third party reproduction.
A man who makes a sperm donation can be known or anonymous to the recipient. Sperm donations made to a known recipient are called directed donations.
You must be screened for medical conditions and other risk factors before you can make a sperm donation. It's also important to understand the possible emotional, psychological and legal issues of sperm donation.
