We have sperm immediately available in our sperm bank for all fertility treatments with the exception of IUI. You can also use sperm from external sperm banks such as London Sperm Bank, Xytex and Cryos. Importing sperm from external banks can take different lengths of time dependent on the bank. Our waiting list for donor eggs is currently around six plus months.   For more information on egg and sperm donation see: https://hertsandessexfertility.com/donation/
