  1. WhenIUI converted toART Dr H Faruk Buyru İÜ İstanbul Medical Faculty Dept of Obstet&Gynecol

  2. Artificial Insemination • Homologous artificial insemination • Heterologous artificial insemination • Artificial insemination, husband (AIH) • Artificial insemination, donor (AID)

  3. Rationale for the use of IUI • Vaginal acidity and servical mucus hostility • Concentrated, motile, morphologically normal sperm as close as possible to the oocytes

  4. Main Indications for IUI • Ejaculatory failure • Cervical factor • Mild male subfertility • Immunological • Unexplained infertility • Endometriosis • Ovulatory dysfunction • HIV positive male partner and HIV-negative female partner • Combined infertility factors

  5. Assisted reproductive technology in Europe, 2004: results generated from European registers by ESHREAndersen et al, Hum Reprod 2008 Apr • From 29 countries, 785 clinics, 367,066 cycles including: IVF (114,672), ICSI (167,192), frozen embryo (71,997), egg donation (ED, 10 334), PGD/PGS (2701) and, IVM (170) • IUI 115,980 cycles (IUI-H, 98,388; IUI-D, 17,592) • No of ET: 1- 19.2%, 2-55.3%, 3-22.1%, 4 or more 3.3% • Singleton 77.2 %, twin 21.7%, triplet 1 %

  6. Steps • Ovarian stimulation • Monitoring of follicular growth andendometrial development • Timing of insemination • Semen preparation • IUI with prepared sperm

  7. Factors Affecting Success Rate • Cause of infertility • Age of both partners • Duration of infertility • Treatment cycle rank • Sperm parameters

  8. Clomiphene citrate and intrauterine insemination: analysis of more than 4100 cyclesDovey S et al, Hum Reprod 2008 • Retrospective cohort study, Boston IVF • 4,199 cycles, 1,738 patients, 2002 - July 2007, CC-IUI • Under age 35 years cumulative PRs 24.2 % • Ages 35-37 18.5 % Ages 38-40 15.1 % • Ages 41-42 7.4 % Above 42 1.8 % • Younger patients have a higher PR per cycle than older patients • The PR per cycle for patients who initiate only one or only two treatment cycles is notably higher than the corresponding per cycle rates for cycles 3 through 9 • The drop in success per patient among 41- and 42-year-olds is sharp, but the exceptionally low success rate above age 42 suggests that CC with IUI has virtually no place in their treatment.

  9. Maternal Age • An age-related decline in female fecundity has been documented in women undergoing IUI • Successful pregnancy rates decrease after age 35 and reduce dramatically after age 40 • Plosker et al, Hum Reprod 1994 • Tomlinson et al Hum Reprpd 1996

  10. Duration of Infertility • The longer the duration of infertility, the lower the pregnancy rates after IUI • The pregnancy rate may be seriously compromised when infertility has lasted 3 or more years • Nuojua-Huttunen S et al , Hum Reprod 1999 • Plosker et al, Hum Reprod 1994 • Steures P et al, Fertil Steril 2004

  11. Semen Analysis Characteristics • Total motile sperm count > 5 million • Kruger morphology 5% • Zayed et al, Hum Reprod 1997 • Prewashed semen specimen: More than 4% normal sperm morphology, the chances of pregnancy after IUI were significantly increased • van Waart et al, Hum Rerprod Update 2001

  12. Thresholdfor IUI > 5X106

  14. Isolatedteratozoospermia

  15. Fertil Steril 2008 393 couples, 714 IUI cycles Prospective observational study

  16. IUI used for treating male factor infertility has little chance of success when the; • woman is older than 35 years, • the number of motile spermatozoa inseminated is <5 x 10(6), • normal sperm morphology is <30%

  17. Endometriosis-Related Infertility Controlled Ovarian Hyperstimulation with Intrauterine Insemination vs. In Vitro Fertilization-Embryo Transfer Dmowski et al., F&S 2002

  18. Endometriosis -Conclusion: • The pregnancy rate achieved by 1 IVF cyle is higher than cumulative rate of 6 COH-IUI cycles (independent of age and the stage of disease), • After 3-4 COH-IUI cycles the success of COH-IUI does not increase, • COH-IUI: • Mild-moderate endometriosis • < 38 years

  19. IUI-Howmanycycles? • 489 cycles OI + IUI • Cycle fecundity rate was 0.07 for the first 4 cycles • 0.03 for the 5-10. cycles • 94% of pregnancies occured in the first four attemtps • Remohi et al; Hum Reprod 1989

  20. COH / IUI :How many cycles? Dickey, 2002 F/S

  21. IUI: How many cycles should we perform?Custers IM et al, Hum Reprod 2008 • Multicentre, retrospective cohort analysis • Primary outcome: Ongoing pregnancy rate (OPR) per cycle • 3714 couples with male, cervical or unexplained subfertility underwent 15,303 cycles of IUI. • In 70% of cycles, controlled ovarian hyperstimulation (COH) was used (51% clomiphene-citrate, 19% gonadotropins). • Mean OPR rate was 5.6% per cycle. OPR in the seventh, eighth and ninth cycle were 5.1%, 6.7% and 4.6%, respectively. • Taking censored patients into account, the calculated COPR was 18% after the third cycle, 30% after the seventh cycle and 41% after the ninth cycle. • CONCLUSIONS: OPR in high-order IUI cycles are acceptable, and do not offer a rationale for cancellation before nine cycles. Using this type of very mild COH, it may be reasonable to conduct up to nine cycles.

  22. Comparison • Success rates • Cost-benefit analysis • Complication rates • The invasiveness of the techniques • Couple compliance

  23. Cost • Initiating treatment with IUI appeared to be more cost-effective than IVF most cases of unexplained and moderate male subfertility • Goverde AJ et al, Lancet 2000 • Karande VC et al, Fetil Steril 1999 • Philips Z et al, Hum Reprod 2000 • Van Voorhis BJ, Fertl Steril 1998 • Nuojua-Huttunen S et al; Hum Reprod 1999

  24. COST: IVF / IUI Before IVF Cohlen (2005) Gynecol Obstet Invest • Review • Cervical factor, male factor (TMS> 10 million), unexplained infertility • Gonadotropins are more effective than CC • Mild ovarian hyperstimulation + IUI is more cost-effective than IVF

  27. IUI / IVF: Cost-effectivenessVan Voorhis et al (1998) Fertil Steril

  28. Outcome: Per live birth-producing pregnancy • IVF :12 600 £ • Unstimulated-IUI + IVF :13.100 £ • Stimulated-IUI + IVF :15.100 £ • Hypothetical cohort of 100 couples: • Compared with primary offer IVF, 6 cycles of “U-IUI” or of “S-IUI” wolud cost an additional £174.200 and £438.000, representing an opportunity cost of 54 and 136 additional IVF cycles and 14 to 35 live birth-producing pregnancies respectively

  29. For couples with unexplained and mild male factor subfertility, primary offer of a fullIVF cycle is less costly and more cost-effective than providing IUI (of any modality) followed by IVF

  30. Intra-uterine insemination for male subfertilityBensdorp AJ, Cohlen BJ, Heineman MJ, Vandekerckhove PCochrane Syst Rev, 2008-1 • IUI versus TI both in natural cycles no evidence of difference (Peto OR 5.3, 95% CI 0.42 to 67) • No statistically significant of difference between pregnancy rates (PR) per couple for IUI + OH versus IUI could be found (Peto OR 1.47, 95% CI 0.92 to 2.37) • IUI versus TI both in stimulated cycles there was no evidence of statistically significant difference (Peto OR 1.67, 95% CI 0.83 to 3.37) • Conclusion: There was insufficient evidence of effectiveness to recommend or advise against IUI with or without OH above TI, or vice versa

  31. Intra-uterine insemination for unexplained subfertilityVerhulst SM, Cohlen BJ, Hughes E, te Velde E, Heineman MJCochrane Syst Revc 2008-1 • IUI vs TI both in stimulated cycles: There was evidence of an increased chance of pregnancy (six RCTs, 517 women: OR 1.68, 95% CI 1.13 to 2.50) • A significant increase in live birth rate was found for women where IUI with OH was compared with IUI in natural cycle (four RCTs, 396 women: OR 2.07, 95% CI 1.22 to 3.50). • There is evidence that intra-uterine insemination (IUI) improves the odds of becoming pregnant for couples with unexplained subfertility compared to timed intercourse. • The addition of fertility drugs to IUI treatment to induce ovulation also improves the chances

  32. Ovarian stimulation protocols (anti-oestrogens, gonadotrophins with and without GnRH agonists/antagonists) for intrauterine insemination (IUI) in women with subfertilityCantineau AEP, Cohlen BJ, Heineman MJ Cochrane Syst Rev 2008-1 • Forty three trials involving 3957 women • The review compared different drugs for ovarian hyperstimulation showing that injections result in higher pregnancy rates compared with oral medication. However, the evidence for this result is not very strong. • This review does not answer the question whether the addition of GnRH agonist or antagonist is useful.

  33. Advantages of IVF over IUI • Higher pregnancy rates • Knowledge obtained about fertilization of oocytes • Cryopersarvation of spare embryos • Severe male-factor infertility • Severe endometriosis • Tubal damage

  34. Should we still perform IUI as IVF-ICSI is promoting so quickly? • All treatment options, side effects, risks and costs should be discussed with the couples • IVF/ICSI is more invasive • Couples should be informed about the real success rates HFB

  35. Conclusion • IUI is relatively an effective method of teratment for certain groups of subfertile couples • IUI is less invasive and cheaper than IVF • Careful selection of patients is important • Patent Fallopian tubes • No endometriosis of moderate and severe degree • No severe degree of male-factor infertility • IVF should be carried out with couples after 4 cycles
