For pregnancy to occur, the sperm must ascend through the female reproductive system, to reach the fallopian tubes and there meet the egg.
During the ascent, the sperm meet with a series of natural barriers that limit their arrival to the tubes. Intrauterine insemination (IUI) is a procedure in which previously trained sperm are placed in the bottom of the uterus, near the time of ovulation, facilitating the encounter of the gametes. Various causes of infertility, both female and male, can be counteracted by the use of this technique.
INDICATIONS OF TREATMENT
Alterations of the cervix that prevent or hinder the passage of sperm.
Ovulatory dysfunctions.
Decreased seminal quality.
Unexplained infertility.
PROBABILITY OF SUCCESS
“The pregnancy rate achieved with homologous intrauterine insemination is 20% and is cumulative over time, reaching up to 60% after 4 cycles.”
