At Cryos, you can buy two types of sperm straws: ICI and IUI.
ICI is unwashed/unprepared sperm. ICI straws can be used for intra-cervical insemination. ICI straws cannot be used for intra-uterine insemination without prior preparation as this may cause a severe allergic reaction. However, you can buy ICI sperm straws for intra-uterine insemination, if your fertility clinic prefers to prepare the sperm prior to the treatment.
IUI is washed/prepared sperm where all ejaculate fluids have been removed. IUI straws can be used for intra-uterine insemination and for intra-cervical insemination.
Both ICI and IUI sperm straws can be used for IVF and ICSI treatment.
Please ask your fertility clinic for advice as to which type of sperm straws to choose.
