The rationale 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.

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

Timing of IUI• Basal Body Temperature

• LH Surge ( urine/serum)

• US

Sites of insemination

• Intrauterine (IUI)

• Intracervical (ICI)

Indications • Male factor subfertility• Unexplained infertility• Endometriosis.• Combined ovulatory and ♂ factor

infertility.• Cervical and immunological infertility• Sexual dysfunction infertility.

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.

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

been reported.

A Cochrane review showed that IUI is superior to TI,

both in natural and in cycles with CoH.

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.

Unexplained infertility

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

Sexual Dysfunction infertility

• Retrograde ejaculation• Vaginismus• Hypospadius• Impotence• Infrequent Intercourse during fertile

period.

IUI in stimulated cycles may be considered while waiting for IVF or when in women with

patent tubes IVF is not affordable.

Factors affecting IUI success

• Age of the female.• Natural cycle versus O.I• Number of IUI treatment cycles. • Site of insemination• Exact timing of IUI

Complications • Relatively low success rate / cycle.

• PID 0.01-0.2%.*

• MP

• Prematurity & low birth weight.**
