(http://www.fertilitext.org/p2_doctor/ai.html) For those women who do not respond to Clomiphene, a more intensive ovulation induction may be needed. Gonadotropins are injectable medications that are made up of a combination of follicle stimulating hormone (FHS) and lutenising hormone (LH) or just FSH alone. These hormones can be successful in stimulating the growth of oocytes into mature graphian follicles within the ovaries, which results in ovulation. However, the ovulation induction procedure may not result in successful conception, the main reasons being male factor infertility or hostile cervical mucus. .
ARTIFICIAL INSEMINATION.
Following unsuccessful ovulation induction treatment, many couples are presented with the option of artificial insemination (AI) in conjunction with ovulation induction. AI is a relatively simple procedure that involves injecting a sample of specially treated sperm from the male partner into the female partner's reproductive tract. For most couples, AI is performed with the husband's sperm. .
There are many types of AI including intracervical, intrauterine, intrafollicular and intratubal, of which, intra uterine insemination (IUI) is the most common. This procedure is carried out by passing a sterile catheter containing the sperm, through the cervix and into the uterine cavity where sperm are injected directly into the uterus, enabling problems such as mild to moderate male factor infertility or hostile cervical mucus to be by passed. IUI is relatively uncomplicated and one of the least invasive fertility treatments, however, the average pregnancy rates per treatment cycle, when performed for the correct indications, is between 15-20%. If all other conditions affecting fertility are thought to be normal or adequately treated, then a reasonable length of treatment with IUI is about three to six treatment cycles.
