Unexplained Infertility
Fewer test Frequent diagnosis
10 – 20% without laparoscopy
<10% after laparoscopy
Prevalence decreases with
advanced test for evaluation
Recommended Investigations
Basic Test
 Semen Analysis (WHO 2010)
 Tubal patency by HSG
 Documentation of ovulation by Urinary LH
surge/ luteal progesterone levels/ trans
vagina USG for documentation of ovulation,
BBT
In selected cases advanced tests can be done
Laparoscopy
Hysteroscopy
Ovarian reserve tests
Sperm function test

patent fallopian tubes do
not necessarily function
normally
Identified/Unidentified Putative and Subtle Abnormalities
Four common conditions when not
diagnosed tend to be labeled as UI
Treatment helps to increase the
chances of conception and
decrease time to pregnancy by
1. Improving gamete quality
2. Increasing gamete
numbers
3. Facilitating gamete
interaction
The Fast Track and Standard Treatment (FASTT) Trial
Conventional Arm Accelerated Arm
3 cycles of CC (at a starting dose of 100 mg on
cycle days 3–7, with LH kit monitoring or
ultrasound monitoring) followed by 3 cycles of
GT (at a starting dose of FSH 150 IU) and then up
to six cycles of IVF
3 cycles of CC followed by up to six cycles of IVF

Forty and Over Treatment Trial (FORT-T)
2 cycles of COS/IUI versus immediate IVF demonstrated superior pregnancy rates with fewer
treatment cycles in the immediate IVF group
Marlene B. Goldman, et al A randomized clinical trial to determine optimal infertility treatment in older couples: the Forty
and Over Treatment Trial (FORT-T)
Standard Arm Direct IVF Arm
2 cycles of CC + IUI (at a starting dose of 100 mg on
cycle days 3–7 or
2 cycles of GT = IUI (at a starting dose of FSH 300 IU)
and then move to IVF if no pregnancy
with LH kit monitoring or ultrasound monitoring, E2
in GT cycles
Immediate IVF
OCP – 21 days
Followed by a microdose leuprolide acetate protocol
(40 mg SC twice/day until the hCG injection) with a
starting dose of twice daily GT 300 IU FSH in the
morning and 150 IU hMG for in the afternoon
No treatment 1.3 %
IUI 4.8 %
CC 5.6 % NNT 76
CC with IUI 8.3 %
GT 8.0 %
GT with IUI 18.0 % NNT 15
ART 30.4 % NNT 4
Aggressive treatment
Combined pregnancy rates per cycle
IUI–effective, simple, less invasive, less stressful & cost effective

Some forms of unexplained infertility could be overcome by IVF, such as
 occult ovulation defects
 subtle disorders of tubal function that cannot be identified with the traditional tests of
tubal patency
 cervical abnormalities
 male factor problems that cannot be identified by standard semen analysis

Some forms of unexplained infertility could be overcome by IVF, such as  occult ovulation defects  subtle disorders of tubal function that cannot be identified with the traditional tests of tubal patency  cervical abnormalities  male factor problems that cannot be identified by standard semen analysis
