What is Intrauterine Insemination?
IUI can be recommended for women up to 36 years of age with an option of three to six cycles. There are however some conditions to be fulfilled. The woman has to have non-obstructed fallopian tubes and the man has to have a normal semen analysis. In the case of Polycystic Ovary Syndrome (PCOS) the hormones like gonadotropins or clomiphene is used to cause the ripening of one to two follicles in the ovary.
How is IUI done?
By injecting the human chorionic gonadotropin the ovulation is triggered. Semen is transferred into the uterus where it migrates through the uterus to the fallopian tube where it meets with the egg cell. Only a single sperm usually fertilizes the egg in the upper part of the fallopian tube. Next the fertilized egg which is later referred to as an embryo begins its five day migration to the uterine cavity. It reaches the uterus in the blastocyst stage and begins to implant in the lining of the uterus (endometrium)
Specific hormones are needed to properly prepare the inner lining of the uterus for the implantation.
