Decreasing sperm quality; legalisation of homo-sexual marriages; and more women chosing to be solo-moms all continuously increase the demand for donor-sperm for fertility treatment. As demand exceeds supply, it has resulted in limited donor variety and inflated prices for donor sperm. Today, fertility clinics directs their patients needing donor-sperm towards legacy sperm-banks, despite fertility clinics having the expertise, equipment, and licenses necessary for processing sperm and handling donors. Fertility clinics show increasing interest in sperm-banking but few have succeeded because it is very different from running a fertility clinic. By becoming a partner clinic (PC) fertility clinics get a large donor assortment at affordable prices - and a share of the attractive profits in the donor-sperm industry.
