Endometriosis and infertility
• The hypothesis that endometriosis causes infertility or a decrease in fecundity remains controversial. • Whereas evidence demonstrates an
association between endometriosis and infertility, a causal relationship has not been clearly established.

Endometriosis and infertility: a committee opinion.

A paradox !
•1. Need to do a laparoscopy to make a diagnosis of endometriosis
![Page 5: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/5.jpg)
•2. No need to do laparoscopy routinely for all infertile couples
![Page 6: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/6.jpg)
Routine laparoscopy
• Laparoscopy in infertile woman, simply to confirm or rule out the disease is not warranted.• Endometriosis and infertility: a
committee opinion. The Practice Committee of the American Society for Reproductive Medicine. ASRM, 2012
![Page 7: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/7.jpg)
Routine laparoscopy
• The benefit of laparoscopic treatment of minimal or mild endometriosis is insufficient to recommend laparoscopy solely to increase the likelihood of pregnancy. • Endometriosis and infertility: a
committee opinion . The Practice Committee of the American Society for Reproductive Medicine. ASRM, 2012
![Page 8: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/8.jpg)
No laparoscopy ? Won’t we miss the diagnosis ?
• Yes, we will • So, what ?• We don’t treat a diagnosis, we treat the
infertile couple !• Treating mild endometriosis , either with
medical therapy or operative laparoscopy, does not improve fertility
![Page 9: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/9.jpg)
Routine laparoscopy• Does not change treatment options - or
outcome !• Burning endometriosis lesions, and
cutting adhesions are fun , but “treating” these doesn't improve fertility – and can actually reduce it • Post hoc, ergo propter hoc fallacy -
Patients get pregnant after the laparoscopy and doctor is happy to take the credit
![Page 10: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/10.jpg)
Harm Caused• Misdiagnosis - corpus luteum vs
endometriosis• Burning or excising chocolate cyst reduces
ovarian reserve• Overtreatment – patient “treated” with
Lupron after the surgery• Wastes time – you tell the patient, you have
now been treated, so you can get pregnant on your own
• Don't cut and burn just because you can !

Medical treatment does not improve pregnancy rates
• In infertile women with endometriosis, clinicians should not prescribe hormonal treatment for suppression of ovarian function to improve fertility.

Changing paradigm
• PAST• Removal of lesions is a
priority.• It is a gynecological
lesion• Recurrence means
incomplete primary surgery
• ART had low pregnancy rates
• PRESENT• Preservation of ovarian
function is a priority.• It is an inflammatory
syndrome• Recurrence means
persistent offending factor
• ART is safe and effective
![Page 14: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/14.jpg)
Principles of care• Ovarian reserve should be assessed
before intervention.• Endometriosis surgery should be avoided
in women with diminished ovarian reserve who should be offered ART straightaway.• ART is the best option in women with
recurrent endometriosis
![Page 15: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/15.jpg)
Principles of care• Don’t just treat the lesions !• Need to factor in:• Female age• Duration of infertility• Pelvic pain
![Page 16: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/16.jpg)
Endometrioma diagnosed on ultrasound
![Page 17: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/17.jpg)
Ovarian Endometriomas
![Page 18: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/18.jpg)
Justification for doing laparoscopic ovarian cystectomy
• Confirm the diagnosis histologically • Reduces risk of recurrence over
fulguration • Reduce the risk of infection at IVF • Improves access to follicles• Improves IVF pregnancy rate ( because
endometriosis fluid is “toxic “ to eggs)
![Page 19: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/19.jpg)
IVF and endometriosis
• Embryo implantation is not affected in patients with endometriosis. • The presence of severe
endometriosis or bilateral ovarian endometrioma does not lower implantation rates.
![Page 20: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/20.jpg)
• Although the presence of bilateral endometriomas at the time of IVF affects responsiveness to hyperstimulation, the quality of the oocytes retrieved and the chances of pregnancy are not affected.

Ultrasound guided cyst aspiration prior to IVF
• Safe and effective• Temporary solution – good
enough• If she gets pregnant in the IVF
cycle, problem is resolved !

Take home messages• Routine diagnostic laparoscopy not indicated
for infertile women
• Medical therapy of endometriosis has no role in improving fertility
• In minimal to mild disease, ovulation induction and IUI is first line therapy.
• IVF is the final common pathway for having a baby
![Page 25: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/25.jpg)
The elephant in the room
• None of us will change what we are doing!• We all have our personal prejudices
![Page 26: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/26.jpg)

Trigger happy doctor
• We like doing things - " Itchy " fingers• Feel good - for yourself, because you did
something• Patient is happy – she feels you have
"diagnosed" the problem and have treated it• Can charge more
![Page 29: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/29.jpg)
Why it’s easy to fool doctors
• Personal experience - Small numbers, no controls, no followup • Patients change doctors. Only the
success stories come back with chocolates !• Reinforces your bias – the easiest person
to fool in the world is yourself
![Page 30: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/30.jpg)
Experts are biased – and often wrong !
• Eminence based medicine - "my experience" - which is plagued with problems• Experts fudge numbers – they lie ! • Sponsored by pharma companies and
medical device manufacturers who want to sell their products
![Page 31: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/31.jpg)
Trust your own eyes !
• Minimal endometriosis is a very common incidental finding • No clinical relevance• Look for it carefully in patients
undergoing lap TL• You will find it in nearly every woman
you put a scope into if you are meticulous
![Page 32: Overtreating endometriosis](https://reader031.vdocuments.us/reader031/viewer/2022021503/5a64ab077f8b9a4c568b5083/html5/thumbnails/32.jpg)
IVF vs Endoscopy
• Do both ! • Gynecologist and Ivf specialist refer
patients to each other ! • Both are happy - only loser is the
patient
