2. Infertility is a failure to conceive
within one or more years of
regular unprotected coitus.
3. Review of physiology of reproductive
system
GnRH ( hypothalamas)
FSH/LH(pituitary)
Estradiol (ovary)
4. Ovarian cycle
Recruitment of groups of follicles (FSH)
Selection of dominant follicle and its
maturation(FSH, highest estrogen containing
follicle)
Ovulation (LH surge, FSH surge)
Corpus luteum formation(maintained by LH,
produces progesterone, life: 12-14 days)
Demise of the corpus luteum ( due to
withdrawal of tonic LH support)
5. Endometrial cycle
Stage of regeneration (2-3 daays after
menstruation)
Stage of proliferation(D5/6 –D14, due to rising
ovarian estrogen)
Stage of secretion( due to estrogen&
progesterone from corpus luteum.D15 to 5-6 days
before menstruation)
Menstruation ( fall in estrogen& progesterone)
17. Coitus after 12 – 72 hours after ovulation
Infection
Stenotic cervical os
Obstruction of os
Repeated cervical surgeries
Anti sperm antibodies
25. Previous Obstetric History
No. of pregnancies, interval between them
Pregnancy related complications
Premature rupture of membranes
Puerperal sepsis
33. Indirect methods
Menstrual history
Features of ovulation
Regular normal menstrual loss
Mittelschmerz syndrome
PMS/ Primary dysmenorrhoea
34. Evaluation of peripheral/ end organ
changes
Basal body temperature : biphasic pattern
Cervical mucus study:
disappearance of fern pattern after 22nd day
suggests ovulation
Loss of stretchablity which was present in
midcycle
36. Hormone Estimation
Serum progesterone: on D8 and D21
Increase from <1ng/ml to 6ng/ml indicates
ovulation
• Serum LH: daily in midcycle
Ovulation occurs 34-36 hours after beginning of LH
surge/ 10-12 hours after LH peak
37. Serum oestradiol: peak rise 24 hours prior to LH
surge and about 24-36 hours prior to ovulation
Urinary LH: ovulation occurs within 14-26 hours of
urinary LH surge
38. Endometrial biopsy: sharman curette /pipelle
endometrial sampler. Done D21- D23.
Evidence of secretory activity in 2nd half of cycle.
Sonography
Graffian follicle prior to ovulation(18-20mm)
Recent ovulation (collapsed follicle and fluid in
POD)
41. LUTEAL PHASE DEFECT ( poor
function of corpus luteum)
BBT chart
Slow rise of temperature taking 4-5 days following
the fall in midcycle
Rise of temperature sustains < 10 days
• Endometrial biopsy (D25 –D27)
Lagging at least 2 days
Serum progesterone
D8: <10ng/ml
42. Luteinised Unruptured Follicle
Sonography: persistence of echo free dominant
follicle beyond 36 hours after LH peak
Laparoscopy
Ovarian biopsy: ovum in the middle of corpus
luteum
44. Dialatation and insufflation test
Done in post menstrual phase at least 2 days
after stoppage of bleeding.
Air/ CO2
Fall in pressure when raised> 120 mmHg
Hissing sound in illiac fossa
Shoulder pain
46. Laparoscopy and chemopertubation
Done in secretory phase
can see recent corpus luteum and take
endometrial biopsy
Laparoscopic visualisation of pelvis, tubes and
ovaries
Inject methylene blue to check tubal patency
47. Sonosalpingography
Under USG
Inject saline / air through a foley’s catheter
Detects tubal patency, peritubal adhesions,
unsuspected endometriosis
48. Hysteroscopy and falloposcopy
To study interstitial part of tube
A soft pliable cannula can be used to brake small
synechiae
49. Ampullary and fimbrial salpingoscopy
To study the mucosa of fallopian tube
Inject starch into pouch of Douglas; presence of
starch in cervical mucous 24 hours after injection
indicates tubal patency
54. Post coital test
Done D12- D13
Report to clinic within 8-12 hours of intercurse
Aspirate endocervical mucus
Visualise under high power microscope
10 progressively motile sperm/HPF : normal
Immotile sperm with normal sperm count:
immunological factors
55. Sperm cervical mucous contact test
In vitro cross over test
Midcycle endocervical mucous & semen
Vs
Donor’s mucus and semen
64. DOSE
Initial 50mg daily; max: 250mg daily
