Intrauterine insemination (IUI) and / or ovulation induction

This may be considered when at least one fallopian tube is patent and semen analysis is normal or near normal.


It involves ovarian stimulation with clomiphane citrate and / or follicle stimulating hormone (FSH or human menopausal gonadotropin). The response to these medications is monitored by ultrasound. Ovulation is triggered by human chorionic gonadotropin (HCG) 5,000 IU when not more than four ovarian follicles reach at least 1.6 cm diam. The semen sample is prepared and is then inseminated into the uterine cavity 24-36 hours later.

Occasionally intravaginal or intracervical insemination is performed when IUI is not technically possible or acceptable by the couple.
Insemination may have to be abandoned when more than four matured ovarian follicles are present.
In some cases, couples may request to have insemination only without prior ovarian stimulation or to have ovarian stimulation only followed by natural coitus.
