IUI donor sperm is washed and purified sperm which has been prepared in a laboratory. IUI sperm is ready for insemination directly into the uterus. The purification of the sperm consists of separating the seminal fluids from the sperm cells and adding a cryo-preservative fluid before preserving the sperm (freezing).

IUI donor sperm is ready to be used for intrauterine insemination at a clinic. The IUI procedure must always be done at a clinic by a trained health care professional.


ICI donor sperm is unwashed, unpurified sperm that contains all the naturally occurring ejaculate fluids.

ICI sperm can be used for the fertility treatment intracervical insemination where the sperm is inserted into the woman’s vagina.

ICI can also be used for IVF and ICSI treatment. Unwashed ICI sperm cannot be used for intrauterine insemination as this may cause a severe allergic reaction. However, you can order ICI sperm for IUI treatment at a clinic if the clinic prefers to prepare the sperm themselves prior to the fertility treatment. We recommend you to ask your clinic for their preferences with regards to the choice of sperm straws before ordering.
