Items addressed

Items Addressed

  • What is IUI.

  • Indications.

  • Effectiveness.

  • Cost Effectiveness.

  • Factors affecting success rate.

  • Advantages and complications.


Iui ovarian stimulation and complications

The rationale behind intrauterine insemination (IUI) with homologous sperm is bypassing the cervical-mucus barrier and increasing the number of motile spermatozoa with a high proportion of normal forms at the site of fertilization.


Iui ovarian stimulation and complications

This interest in IUI is undoubtedly associated with the refinement of techniques for the preparation of washed motile spermatozoa.


Semen preparation techniques

Semen Preparation Techniques

  • Swim up.

  • Albumin

  • Percoll

  • Minipercoll

  • Glass wool filtration

  • Sephadex separation

  • Migration sedimentation

  • Glass blood separation


Iui ovarian stimulation and complications

The washing procedures are necessary to remove prostaglandins, infectious agents, antigenic proteins, non-motile spermatozoa, leucocytes and immature germ cells.


Iui ovarian stimulation and complications

This may enhance sperm quality by decreasing the formation of free oxygen radicals after sperm preparation. The final result is an improved fertilizing capacity of the sperm in vitro and in vivo.

Sites of insemination

Sites of insemination

Intrauterine (IUI)

Intracervical (ICI)

Intraperitoneal (IPI)

Cap insemination

Trans cervical / intrafallopian (ITI)


Iui ovarian stimulation and complications

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.


Iui ovarian stimulation and complications

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.

Indications

Indications

Male factor subfertility

Unexplained infertility

Endometriosis.

Combined ovulatory and ♂ factor infertility.

Cervical and immunological infertility

Sexual dysfunction infertility.


Iui ovarian stimulation and complications

Male Factor Subfertility

In long standing infertility caused by reduced sperm quality expectant treatment seems to be disappointing with a spontaneous conception rate of only 2% per cycle.

Male factor Infertility (OAT)

  • Oligozoospermia (O)

  • Asthenozoospermia (A)

  • Tratozoospermia (T)


Male subfertility

Male subfertility

In male subfertility IUI with or without COH a pregnancy rate of 10-18% per cycle has been reported.

-Stone BA et al 1999. Am. J Obstet Gynecol, 180:1522-1534

Male subfertility1

Male subfertility

A Cochrane review showed that IUI is superior to TI, both in natural and in cycles with CoH.

Cohlen BJ et al 2000. (Cochrane Review)

Cochrane library, issue 4, update software, Oxford.


Iui ovarian stimulation and complications

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.


Iui ovarian stimulation and complications

IMC and sperm morphology are the most valuable sperm parameters to predict IUI outcome in male subfertility.

  • Ombelet W et al 2003. Reprod Biomed Online 2003;7:485-492

  • Duran EH et al , 2002. Systematic Review. Hum. Reprod Update ;8:373-384


Iui ovarian stimulation and complications

There is a trend towards increasing conception rates with increasing IMC, but the cut-off value above which IUI seems to be successful, however varies between 0.3 and 20X106 .

  • Ombelet W et al 2008. Hum. Reprod. Doi:10.1093/humrep/den165


Iui ovarian stimulation and complications

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. J. Androl; 18:448-453


Iui ovarian stimulation and complications

A cut off level of:

0.8 million motile spermatozoa after washing .

Ombelet W et al 2008). ESHRE Monograph , 1: 64-72


Iui ovarian stimulation and complications

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


Iui ovarian stimulation and complications

When controlled ovarian hyperstimulation (COH) is used, IUI becomes effective compared with TI

Cohlen BJ. Gyn. Obst. Invest ;2005;59:3-13


Iui ovarian stimulation and complications

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


Iui ovarian stimulation and complications

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.

Cohlen BJ. Gyn. Obst. Invest ;2005;59:3-13


Sexual dysfunction infertility

Sexual Dysfunction infertility

Retrograde ejaculation

Vaginismus

Effectiveness

Controversy still surrounds the effectiveness of this very popular treatment procedure.


Eshre capri workshop group

ESHRE Capri Workshop Group

  • Stimulated IUI is ineffective in male infertility and the effect on other diagnoses is small.

  • IUI+CC PR 7% /cycle

  • IUI+ FSH PR 12 %/ cycle

  • IUI+FSH MP 13 %

  • Prevention of premature LH | not a major

  • Luteal phase support | requirement

Pregnancy rate per cycle and number needed to treat (NNT)per cycle

*Pregnancy rate per cycle is from Reindollar et al. (2007). NNT is from Deaton et al. (1990) before crossover.


Iui ovarian stimulation and complications

ESHRE Capri Workshop Group

IUI in stimulated cycles may be considered while waiting for IVF or when in women with patent tubes IVF is not affordable.

ESHRE - Hum Reprod. Update, 2009

Vol,15, No. 3, 265-277


Iui ovarian stimulation and complications

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.

ESHRE- Hum Reprod. Update, 2009

Vol,15, No. 3, 265-277


Iui ovarian stimulation and complications

Most studies are retrospective.

Studies vary in:

- Comparison of study groups.

- Use or non use of MOH.

- No of inseminations/treatment cycle.

- Different sites of insemination.

-Various methods of sperm preparation.

- Use/non use of additives as antioxidants, platelet activation factor (PAF)…etc

Unexplained and moderate ♂ factor subfertility

Effectivity has been documented in controlled studies under the condition that the inseminating motile count exceeds more than 1 million motile spermatozoa.

Ombelet W. et al. Hum Reprod, 2008 , doi:10.1093/humrep/den165


Iui ovarian stimulation and complications

A comparable cumulative ongoing PR after three IUI cycles for all couples, providing the IMC was more than 1 million was obtained.

  • Ombelet W et al 1997. Hum. Reprod. 12:1458-1463


Iui ovarian stimulation and complications

Cost effectiveness

Published data comparing cost of IVF versus IUI indicate that initiating treatment with IUI appeared to be more cost-effective than IVF in most cases of unexplained and moderate male subfertility

- Ombelet W. et al 2003. Reprod Biomed Online; 7:485-492

- Ombelet W. et al 2005. Hum. Reprod. Update ; 11:3-14


Iui ovarian stimulation and complications

In a systematic Review Garceau et al (2002) showed that initially treatment with IUI appears to be more cost-effective than IVF in most cases of unexplained and moderate male subfertility.
