This is intrauterine insemination where the husband semen/donor semen is washed to remove the debris, pus cells & bacteria & is slowly put Inside the uterine cavity by the special catheter (Insemination canula). The process is painless, easy & OPD procedure. It requires no sedation or anaesthesia. It increases the chances of pregnancy as the semen quality is improved by washing, the quality of egg is improved by medicine & the timing of insemination is set with the ovulation.
The ovaries are gently stimulated with clomiphene citrate tablets either alone or with low dose hormone injections followed by ultrasound monitoring until the follicles are mature when HCG trigger is given. The aim is to stimulate the release of one or two eggs only. Once day of ovulation can be predicted, insemination will be timed to within 24 hrs. unlike IVF, precise timing is not critical.
No, it is a time-tested procedure. Washing help in removing bacteria dead cells, pus cells, only. The couple can see the difference in the quality of sperm count by pre & post-wash analysis shown in the lab.
With IUI although the time of insemination is coincided with ovulation but, the meeting of sperm with egg (fertilization), the transport of fertilized egg through the tube, its implantation in the uterus & the further continuation of pregnancy, all these events are left to nature only, resulting in success rate of 15-18% worldwide, hence IUI is offered successively for 4 to 6 cycle.
