IUI and Sperm

Karen

Hi my Dr is going to put me on Clomid and do <a href="https://glowing.com/glow-fertility-program">IUI</a>. My husband is going to be out of town during the ovulation time. Does anyone know if the semen can be taken prior to him leaving or does it have to be collected the day of the <a href="https://glowing.com/glow-fertility-program">IUI</a>?
