- aim for 37/40/MOD individualized
*if AEDF - consider 2nd daily dopplers…
results of rpt doppler of EOIUGR show
- AEDF or REDF
- decreased MCA PI
- placental insufficiency -> hypoxia -> brain sparing
- timing/mod individualized
- discuss with MFM

(encounter 2)
HE - nipple dc/ha/visual field
- repeat prolactin
- organize MRB
- f/U to review result
+/- refer to endocrinologist +/- neurosurg
(prl still high, MRB showed microadenoma)
- benign tumor
- r2u - expansion/compression/reduced ovulation/infertility
- r2b - no impact on baby
- preg possible post treatment, cease during preg, monitor sx in preg, nil CI to BF
- use contraception during treatment/serum prl 1mo post rx then 12/12 post+MRB
- dopamine agonist (bromocriptine)/transphenoid surgery
- may need ovulation induction if cycle remains irregular
dopamine agonist can be used in preg if concern of tumor expansion/monitor sx +/- MRB, req MFM/Obs Med input
**risk of expansion in preg higher with macroprolactinoma
**don’t repeat prolactin in pregnancy
**cease dopamine agonist if breast feeding

(encounter 2)
? change in Hx/Exam
OI Mx options
- 1st line = Letrozole vs Clomiphene + Metformin
- 2nd line = Gonadotropin (FSH) + USS monitor vs Ovarian drilling
- 3rd line = IVF
Risks
- OHSS/Multiple pregnancy (less so for letrozole)
Plan
- D1 menses bHCG
- D3-7 Letrozole 2.5mg/Clomid 50mg
- D10-12 TV USS to check for dominant follicle
- D10-20 IC alt day
- D21 P4
- Menses (if not do bHCG)
*letrozole is 1st line but still off-label
**Clomid sx - hot flushes/abdo discomfort
OI with clomiphene, follicle tracking showed multiple dominant follicles, dominant being 17-27mm, what now (encounter 3)
Dx
- multiple dominant follicles increase risk of multiple preg if IC
- risk to you include GDM/PET/operative delivery
- risk to baby include PTB/FGR/SB
Mx
- abstain from IC or use barrier contraception
- try letrozole for OI next cycle

*mx of theca lutein cyst (excess bHCG - hyperplasia of theca interna cells) is essentially analgesia/antiemetic and observe +/- aspiration/pelvic USS to check for resolution/monitor for sx of torsion
dyspareunia/dysmeno
PI bloods/SA = NAD
(encounter 2)
? any change in hx/exam
Dx
- Bloods excludes ovulatory cause of PI
- History suggestive of endometriosis
- Endometriosis can result in anatomical distortion -> infertility
- Imaging such as HSG and HyCoSY can shed some light
- Can’t always reliably detect anatomical distortion, tubal patency, and exclude uterine anomalies (e.g. septum)
For the purpose of PI Ix, I would recommend
1. Diagnostic lap +/- rx of endometriosis w aim to restore anatomy
2. Hysteroscopy +/- polypectomy - ?fibroid/septum/remove polyp
3. Dye studies to check tubal patency
It is a day procedure, GA, General Risks - infection/bleeding/VTE/injuries… Specific risk - staged procedure…quick recovery, F/U post procedure
*endometrial biopsy is not routine infertility ix anymore!!! do a curette when there’s concern about hyperplasia/AUB…
PI, suspect endo
diagnostic lap
stage 4 endo/ovaries stuck on bowel
large endometrioma >4cm
tubes/uterus normal
discuss finding & ongoing mx
(encounter 2)

suspect endo
diagnostic lap
stage 2 endo - right hydrosalpinx/endometrioma/patent left tube

(encounter 2)
Hx/Exam
- pain/bleeding/post op recovery
- vitals/scar healing
Endometrioma/hydrosalpinx/adhesion/distorted anatomy
All contribute to infertility and chronic pelvic pain
To improve fertility outcome + pain
- refer to MD Endo unit for Gynae/CR rv
- MDT for pre-op planning
- laparoscopic excision of endo/division adhesion/salpingectomy
- multi-D, GA, laparoscopy, path, follow-up
- risks include general/specific - reduce ovarian reserve/recurrence
- TCC 3-6/12, if fail then refer to CREI - IVF
Other modalities to complement surgery for pain mx if no fertility desired
- hormonal suppression with progesterone PO/Depo/Implant/IUS
- refer to pain specialist/pain psychology/PF PT
AMH should be done if planning to or post endometrioma excision
**consider CREI if reduced ovarian reserve (from endometrioma excision)+/- salpingectomy
**endometripma excision improve accesss
6/12 post severe endo excision
still can’t conceive, what next
(encounter 3)
? change in hx/exam
Mx
- Most effective form of ART for endo-related infertility is IVF
- Alt = OI alone, superovulation + IUI but limited evidence
- Refer to REI specialist for consideration of IVF
- IVF involves
1. ovarian superovulation with FSH
2. follicle tracking with TV USS/trigger/egg retrieval 38/24 post
3. fertilization/embryo culture
4. embryo transfer or embryo freezing, transfer on D3 or D5 + P4 pessary given for luteal support
- risk includes OHSS, multiple pregnancy
*trigger when follicle >18mm
**OI - also estrogen lvl tracking every 1-3 day from day 2 of cycle until HCG trigger
