If a person is physically away at the time of procedure or if he cannot produce the semen sample when required, he has to follow these steps. Before semen freezing, he has to undergo the complete blood checkup, which is done to rule out the possibility of HBsAg, HIV or gonorrhea. Then semen sample has to be produced by masturbation into the sterile container, which is provided by lab. Once the semen is given to the lab, a complete semen analysis is performed. After that the semen is freezed and can be revived on the IUI day.
