Unexplained Infertility
![Page 4: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/4.jpg)
Definition
Unexplained infertility means that ,couple does not conceived after 1 year of unprotected vaginal sexual intercourse, with basic infertility evaluation shows no obvious abnormality
(RCOG guidelines,1998; Randolph,2000; ASRM,2006).
Incidence
15% to 30% of infertile couples (ASRM,2006)
![Page 5: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/5.jpg)
Basic investigations for diagnosis of Unexplained infertility
Normal basic semen analysis according to
WHO criteria (WHO ,2010).
Patent fallopian tube confirmed by HSG.
Ovulation confirmed by mid-luteal serum
progesterone level.
![Page 6: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/6.jpg)
In unexplained infertility: the cause is not defined ,so the treatment is empirical (ASRM, 2006).
Expectant Encourage Advice Inform
Active IUIIUI Oral stimulating agents (CC / Oral stimulating agents (CC /
letrozole)letrozole) CC+ CC+ IUIIUI Gonadotropin injections with or Gonadotropin injections with or
without without IUIIUI IVF/ICSIIVF/ICSI Alternatives:Alternatives:
Bromocriptine, Danazol, Tubal flushing.

Treatment
Dependent on:
○ Availability of resources ,
○ Patients’ age ,
○ Duration of infertility.
The standard protocol is to:
○ Progress from simple to complex treatment options,
○ Balance the effectiveness against the cost and side effects. (Ray et al,2012)

Intrauterine Insemination
Definition
IUI involves the placement of
processed semen into the
uterine cavity around the time
of ovulation (Allahbadia and Merchant,2012).
![Page 12: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/12.jpg)
Rationale
increase the rate of
conception by
increasing the chance
that maximum number
of healthy sperms
reaches the site of
fertilization (ESHRE,2009).
![Page 13: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/13.jpg)
IndicationsI. Male:
1. Ejaculatory failure: ( sever hypospadius ;retrograde
ejaculation; impotence)
2. Male factor infertility (mild ;moderate)
3. Sperm cryopreservation prior to treatment of
husband cancer.
4. Processed semen of HIV + husband for HIV
negative women (NICE, 2013)
![Page 14: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/14.jpg)
II. Female:
1.Cervical factor infertility
2. Endometriosis
3. Ovulatory dysfunction
4. Combined non-tubal
infertility factors
III. Combined:
1. Unexplained infertility
2. Immunological infertility
![Page 15: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/15.jpg)
Steps
Patient selection & counseling.
Natural cycle IUI
Stimulated cycle IUI (Ovarian stimulation)
Monitoring of treatment
Sperm preparation
Insemination
![Page 16: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/16.jpg)
![Page 17: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/17.jpg)
Advantages of IUI
• Non invasive (like Pap smear).
• Bypass possible cervical mucous
hostility.
• Easy: performance and training
• Minimal: cost and risk

IUI Complications
Of the procedure
Infection Pain Psychological (guilt,
anger, loss of self esteem)
Of COH Multiple
pregnancy
OHSS
Antenatal & perinatal
As pregnancies from sexual intercourse.

IUI Indications in Unexplained Infertility
![Page 20: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/20.jpg)
ESHRE Capri Workshop Group (2009)
IUI or stimulated ovary/IUI is indicated as
empiric treatment for all categories of
unexplained infertility
20% of couples after initial work-up.
Couples with mild male subfertility (20–40%)
50% of those in whom conventional
treatments have failed.
![Page 21: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/21.jpg)
NICE Guidance Feb, 2013
In the treatment of unexplained infertility
The evidence does not support the use of IUI as
an alternative to expectant management .
IUI (with or without stimulation) should not be
routinely offered (exceptions e.g. when people
have social, cultural or religious objections to IVF)
![Page 22: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/22.jpg)
Effectiveness of IUI in treatment of unexplained infertility
![Page 23: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/23.jpg)
(Guzick et al. 1998.)
Conclusions (Cochrane, 2012 ): In stimulated cycles PR was higher with IUI compared to timed intercourse
Treatment % preg
Expectant (No treatment ) 1.3%
Natural cycle IUI 3.8%
Clomiphene 5.6%
Clomiphene+ IUI 8.3%
Gonadotropins 7.7%
Gonadotropins+ IUI 17.1%
IVF/ICSIIVF/ICSI 20.7%20.7%
Unexplained Infertility :PR with different treatment Options
![Page 24: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/24.jpg)
NICE Guidance Feb, 2004 ; For unexplained infertility
ovarian stimulation should not be offered, even though
it is associated with higher pregnancy rates than
unstimulated IUI, because it carries a risk of multiple
pregnancy.
Cochrane, 2012 ; risks and alternative treatment options
of stimulated IUI should be discussed.
NICE Guidance Feb, 2013 ; Do not offer oral ovarian
stimulation agents (such as clomifene citrate,
anastrozole or letrozole) to women with unexplained
infertility.
![Page 25: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/25.jpg)
IUI versus alternative insemination techniques
1 } Fallopian Tube Sperm Perfusion (FSP) :
Past : FSP is superior to IUI (Trout & Kemmann,1999) .
Later: a meta-analysis reported no clear benefit (Cantineau et
al, 2009)
2} No difference between IUI and Intraperitoneal
insemination (IPI) (Noci et al,2007)
3} Intrauterine tuboperitoneal insemination (IUTPI) is
superior to IUI &FSP (CPR/cycle 29.4% ) (Mamas, 2006)
4} IUI is superior to Intracervical insemination ICI (Besselink et al,2008).
![Page 26: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/26.jpg)
IUI Vs. IVF for unexplained infertility
Starting treatment with IUI rather than IVF was
either cheaper or more cost-effective than IVF in
unexplained infertility (Goverde et al., 2000).
Cochrane, 2012 (Pandian et al, 2012)
IVF may be more effective than IUI+SO.
Due to lack of data from RCTs the effectiveness of
IVF for unexplained infertility relative to
expectant management, clomiphene citrate and IUI
alone remains unproven.
![Page 27: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/27.jpg)
For people with:
○ unexplained infertility,
○ mild endometriosis or
○ mild male factor infertility,
who are having regular unprotected sexual intercourse:
advise them to try to conceive for a total of 2
years before IVF will be considered .
NICE Guidance Feb, 2013
![Page 28: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/28.jpg)
IUI in stimulated cycles may be considered while
waiting for IVF or when in women with patent tubes,
IVF is not affordable (ESHRE Capri Workshop Group, 2009)
![Page 29: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/29.jpg)
Favorable Predictors of IUI Outcome
Factors related to couples
Factors related to therapy
![Page 30: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/30.jpg)
A.Couple:
1.Female age ≤ 35y (Morshedi et al, 2003 )
2.Shorter duration of infertility .
3. Type of infertility (Guven et al,2008)
Type of infertility Pregnancy ratePrimary inf. 7.9%
Secondary inf. 21.4
![Page 31: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/31.jpg)
A.Couple:
4. First treatment cycles (≤ 4). Pregnancies resulting from IUI occur during the first 3-4
treatment cycles (88-95.5%; respectively) (Morshedi et al,2003).
Aboulghar et al, 2001, suggested a maximum of 3
COH/IUI cycles for treatment of unexplained infertility
However ,others recommended up to 6 cycles
(Dickey et al, 2002; Morshedi et al,2003; Ray et al, 2012).
![Page 32: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/32.jpg)
5. Cause of infertility: (Bourn Hall clinic, 1999 ;Tay et al,2007; Wang et al,2008).
Overall CPRs/cycle Higher PR with :
○ Unexplained infertility (9.2% to 22% )○ Ovulatory dysfunction (19.2%)
Modest PR → Cervical factor (16.4%)
Poor PR:○ Endometriosis (11.9%)
○ Immunological infertility (10% )
♂ factor → the best PR with ejaculatory disorders (13.3%)
![Page 33: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/33.jpg)
B. Therapy: (Allahbadia and Merchant,2012).
1 .Use of CC/HMG-FSH compared with CC only .
2 .Follicular dynamic:
- AFC > 5 (Ombelet et al, 2003)
- Preovulatory follicles : 2–3 follicles≥ 16 mm with
uniformly high-grade vascularity and E2 levels >500
pg/mL on the day of hCG administration. (Steures et al, 2004;
Bhal et al ,2001).
![Page 34: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/34.jpg)
.3 .Sperm parameters: generally
• Processed total motile sperm count ≥ 10 million, 24 h
survival > 70%, and normal sperm morphology of >4%
(according to Kruger’s criteria) predict pregnancy
outcome with 94% sensitivity, 86% specificity (Guven et al,
2008;Abdelkader & Yeh ,2009).(12.3 vs 2.8%)
• Initial sperm count, motility ?
![Page 35: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/35.jpg)
4.Time of insemination ,
preferably between D13 &16.
5 .Endometrium:
adequate thickness with trilaminar pattern(Tomlinson et al ,1996)
![Page 36: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/36.jpg)
Measures does not affect IUI results
1. US monitoring & HCG induction of ovulation
versus urinary LH monitoring of ovulation.
HCG allow final follicular maturation (Kosmas et al, 2007)
2. GnRH agonist and antagonist. ↑complications (Allahbadia and Merchant,2012).
3. Double IUI versus single IUI (Polyzos et al,2009).
![Page 37: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/37.jpg)
4. Type of catheter: no significant difference in PR when
using the softer Wallace catheter or the less pliable
Tomcat catheter during IUI, with the standard gentle non
touch technique (Smith et al ,2002).
However , Merviel et al ,2010 recommended soft catheter.
5 . Luteal phase support do not appear major
requirements in IUI cycles (ESHRE ,2009)
6. Sperm preparation technique (ESHRE,2009).
![Page 38: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/38.jpg)
How to improve IUI results?Measures to↓ complications:
1. Natural cycle IUI: ↓ PR
2. Mild ovarian stimulation : low dose GnH
3. Cycle cancellation {> 3 follicles ≥ 16mm or; > 8
follicles ≥ 12mm}
4. Selective follicular reduction. (not routine)
4. Conversion to IVF cycle
![Page 39: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/39.jpg)
How to improve IUI results?Measures to↑ PR:
1. COH: all except sever male factor ( Risks???)(Cohlen ,2002).
2. Vaginal misoprostol.???? (Brown et al,2001; Barroso et al,2001).
3. 10 -15minutes bed rest after IUI (Saleh et al,2000 ; Custers et al, 2009 )
4. Cervical mucous aspiration before IUI (Paasch et al, 2007)
![Page 40: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/40.jpg)
5. Timed intercourse within 12 -18 h period: useful in IUI with low
number of motile sperm inseminated (Huang et al, 1998).
6. Postponing IUI until the observation of follicle rupture by TV
sonography ( PR;25% vs 8.8%) (Kucuk ,2008).
7. US guidance in IUI
(Ramón et al,2009; Oztekin et al,2013)
8. Pre-insemination hydrotubation
(Edelstam et al, 2008; Aboulghar et al, 2010 ; Morad & Abdelhamid , 2012)
![Page 41: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/41.jpg)
1. Treatment of unexplained infertility is empiric as no obvious abnormality was detected.
2. Treatment of unexplained infertility is very much dependent on availability of resources and patients’ age and duration of infertility .
3. OH with IUI is a simple ,cost-effective, least invasive first-line treatment for Unexplained infertility.
![Page 42: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/42.jpg)
4.Couples should be fully informed about the risks of IUI and COH as well as alternative treatment options.
5. In unexplained infertility OH with IUI may be considered while waiting for IVF or when IVF is not affordable.
6. The pregnancy rates of FSP & Standard IUI are similar.
![Page 43: Intra uterine insemination for unexplained infertility](https://reader033.fdocuments.in/reader033/viewer/2022061611/554b139bb4c90569098b4aea/html5/thumbnails/43.jpg)
7.Pre-insemination hydrotubation, US guided IUI , cervical mucous aspiration, post-insemination bed rest for 10 min and vaginal misopristol may improve IUI outcome .
8. In unexplained infertility, up to 6 cycles of IUI should be considered before shifting to IVF.
