Traditionally, gynecologists have used fresh semen samples (ejaculated recently} for TID. However, using fresh semen samples for TID can be hazardous to the patient's health. It is best to use frozen cryopreserved, tested samples from a sperm bank for TID. It used to be felt that pregnancy rates with frozen samples were poor as compared to fresh samples. However, recent studies have shown that if the frozen samples contain a sufficient number of motile sperm, pregnancy rates with fresh and frozen samples are comparable.
