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. 
10/28/14 4
Semen Preparation Techniques 
-Swim up. 
-Albumin 
-Percoll 
-Minipercoll 
10/28/14 5
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.
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 subfertility 
In male subfertility IUI with 
or without COH a pregnancy 
rate of 10-18% per cycle has 
been reported.

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

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.

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.**
