Artificial insemination (IUI)
Intrauterine Insemination (IUI)
also called as Artificial Insemination
is a procedure where washed and prepared sperm is inseminated into the woman’s uterus close to the ovulation period, to facilitate fertilization. IUI can be performed in natural cycles or through stimulating the ovaries with hormones and ovulation is monitored in order to know the best time to carry out the IUI procedure. IUI treatment can be considered when there is a prolonged infertility
, when the sperm has difficulty reaching the uterus, ovulatory dysfunction, minor tubal defects, etc. If there are no positive outcomes achieved after 3 or 4 attempts, more complex techniques such as IVF
may be considered.
There are 2 options available for IUI treatment -
Artificial insemination with partner’s sperm
Artificial insemination with donor sperm
Stages of IUI
On day three of menstrual cycle, hormones such as FSH (or in some cases luteinizing hormone LH) is injected to stimulate the ovaries. The follicle size and number is monitored through ultrasound to determine the right time for insemination. As one or two follicles have reached their optimum size, HCG shot is administered to trigger ovulation and release the egg. The IUI will be scheduled 24 - 36 hours after the HCG shot.
On the day of the insemination, a fresh semen sample is collected and is prepared, washed and sufficient concentration of motile sperm is obtained.
On the day of ovulation, the highly motile semen sample is placed in a fine catheter and inserted into the uterus. The IUI procedure is painless and will take around 20 minutes.
