The final result is an improved fertilizing capacity of the sperm in vitro and in vivo. Aitken RJ, Clarkson JS et al.

Sites of insemination • Intrauterine (IUI) • Intracervical (ICI) • Intraperitoneal (IPI) • Cap insemination • Trans cervical / intrafallopian (ITI) Since IUI programmes are easy to run Cheap and do not need sophisticated equipment IUI is an attractive choice for the treatment of some infertility cases in resource poor countries. 4/8/2015 12 It is generally accepted that intrauterine insemination (IUI) should be preferred to more invasive and expensive techniques of assisted reproduction and be offered as a first-choice treatment in some cases of subfertility.

(Cochrane Review) Cochrane library, issue 4, update software, Oxford. 4/8/2015 19 IUI in natural cycles should be the treatment of choice in case of male subertility, providing an insemination motile count (IMC) of more than 1 million can be obtained after sperm preparation and in the absence of a triple sperm defect ( according to WHO criteria) . Cohlen BJ et al 2000. (Cochrane Review) Cochrane library, issue 4, update software, Oxford. 4/8/2015 20 IMC and sperm morphology are the most valuable sperm parameters to predict IUI outcome in male subfertility. -Ombelet W et al 2003.

Hum. Reprod. Doi:10.1093/humrep/den165 4/8/2015 22 In cases with < 1 million motile spermatozoa, IUI remains successful provided the sperm morphology score using strict criteria is 4% or more (cumulative ongoing PR of 21.9% after three IUI cycles). -Centole GM 1997.

ESHRE Monograph , 1: 64-72 Unexplained infertility Meta –analysis comparing IUI and TI in natural cycles showed no difference in results; therefore, IUI in natural cycles seems ineffective in case of unexplained infertility. Cohen BJ. Gyn. Obst. Invest; 2005,59:3-13 4/8/2015 26 When controlled ovarian hyperstimulation (COH) is used, IUI becomes effective compared with TI Cohlen BJ. Gyn. Obst. Invest ;2005;59:3-13 4/8/2015 27 There is evidence that IUI with COH increases the live birth rate compared with IUI alone. The likelihood of pregnancy was also increased for treatment with IUI compared with TI in stimulated cycles. Verhulst SM et al. Cochrane Database Syst Rev 2006;18::CD001838 4/8/2015 28 Cervical Factor Infertility The results of a meta-analysis of randomized controlled trials comparing IUI with timed intercourse (TI) for couples with cervical factor infertility showed a significant improved probability of conception for IUI. 4/8/2015 Cohlen BJ.

Update, 2009 4/8/2015 Vol,15, No. 3, 265-277 34 In most of these indications, IUI or stimulated ovary/IUI is empiric treatment since it is likely that the majority of infertility involves factors that are untreatable or unknown.
