Y factor is founded by Ole Schou, owner of Cryos International, the world's largest sperm bank. With over 40 years of experience in the fertility industry, he recognised first-hand the need for a more inclusive alternative to traditional sperm banks. Ole founded Y factor to provide this alternative, creating a service that emphasises personal connections and gives users control through a transparent process.

I want to be a sperm donor because it's a meaningful way to help individuals or couples who are unable to conceive on their own. Knowing I could play a part in creating a family gives me a strong sense of purpose and contribution. It also aligns with my desire to make a positive, lasting impact in someone else's life.
Y factor is designed for safe and thoughtful connections, based on mutual preferences for the donation and post donation relationship.
