Some women’s immune systems reject their partners’ sperm as invading molecules, or they have issues with their cervix. IUI helps eliminate the problem by allowing sperm to pass through the cervix to result in fertilisation.

IUI is the act of injecting sperms into the uterine cavity. At the time of ovulation, natural or after stimulation, the male partner produces a semen sample. Sperms are separated from the fluid, and after treatment, the active swimming sperms are collected and condensed in a small amount of culture fluid. This is injected via a fine catheter into the uterus. This is an office procedure that requires no surgery, and normally is the first step in assisted reproduction.
