Intrauterine insemination is the oldest and simplest method of infertility treatment.
It requires that certain conditions are met: healthy sperm in a man, so-called normspermia, then passable fallopian tubes, and proven ovulation in a woman. A good reaction to the treatment stimulation in the woman is presupposed when a sufficient number of oocytes for fertilization are retrieved.
Unfortunately, our society has recently experienced both a significant decrease in sperm quality and an increase in the incidence of non-functioning ovaries in women. As such, the success of IUI as a treatment for infertility is becoming smaller and smaller. Intrauterine insemination is recommended mainly to couples whose natural effort to conceive is not successful but no cause of infertility is discovered.
