Intrauterine Insemination

This is usually done in couples in whom the male partner has slightly reduced sperm numbers or movement, in cases where no cause can be found (unexplained infertility), in cases where ovulation induction and timed intercourse have failed to produce a pregnancy etc.

Ovulation induction is done as described previously. Our aim is to produce the growth of two to three follicles. When they reach about 18mm, an injection (HCG) is given to cause release of the egg.

Egg release or ovulation occurs about 36 hours after HCG injection is given. At this time, the partners semen is collected and prepared by either ‘swim up’ or ‘density gradient’ technique. This process which is also called sperm washing removes debris and makes the sperms very active. Once follicle rupture is confirmed by scan, the sperms which have been prepared are injected slowly into the uterus by a fine catheter or tube.
