Infertility management for GPs: carrier screening, at-home semen testing, ovulation timing, HyCoSy and what AMH really means

Speaker

Fertility / reproductive medicine specialist — identified by role only. Otter labels the main teacher “Speaker 2”. No name is spoken clearly. They joke that they “look like an IVF specialist” and discuss theatre HyCoSy, ovarian drilling and IVF pharmacies in the first person. “AMH interpret with Kotha” appears once in the ASR (session context, not a named guest speaker).

Audience

GPs ask about ordering carrier screening in pregnancy, pathology duplicate claims, and metformin alternatives for PCOS (unnamed). Soft product mention of an at-home semen-analysis company (ASR “SAPYEN” / ~$64 for the simple kit); the speaker says the company’s general manager previously worked at City Fertility and that results matched an andrologist reading a microscope.

Session context

Otter title Infertility Management Seminar · id ytL-iyLUSUCDj51t3H0T85lVKDw · ~25 min, recorded 21 March 2026 3:18 pm AEST (same CPD afternoon as the surgical case discussion). Opens with a thank-you for a referral and a handout of “specifications” for work-up.

Key messages for GPs

• Offer reproductive carrier screening to anyone trying to conceive or already pregnant (as stated in guidelines the speaker referenced). Medicare funds the common three-gene panel once; test the woman first, then the partner if she is a carrier.
• Male factor is easy to miss and easy to fix once found. At-home semen kits can reduce the “car park / lab appointment” barrier; results go back to the patient.
• Many “infertile” couples are timing poorly — LH surge → egg about 24 hours later; a clinic trigger at a known clock time is more predictable than nature.
• HyCoSy (and, when already in theatre, treating stage 1–2 endometriosis) can “flush and optimise” the environment for the next 12–24 months (as stated).
• Metformin for PCOS: speaker’s reading of current guidance is to use it when there is metabolic syndrome / risk factors, not automatically for every lean PCOS patient. Titrate slowly.
• CoQ10 300 mg twice daily for ≥2 months before IVF (as spoken) — speaker puts most patients on it.
• Low AMH ≠ “you can’t get pregnant.” It is more like how much is left in the savings; PCOS can inflate the number. Egg freezing is not benign and many banked eggs are never used.

Start with a complete work-up (or decide sooner)

If the referral already includes a full testing catalogue, the specialist can often decide treatment timing on the first visit. If nothing has been done, the prenatal / reproductive work-up starts in primary care. The speaker handed out a list of the investigations they would order as an IVF-style specialist.

Reproductive carrier screening — once, for everyone trying

Key points as spoken:

• Medicare has funded reproductive carrier screening for about 20 years for the common three conditions (speaker: roughly one in 30 carrier rate for those, “far more common”).
• Test the woman first. If negative, stop. If she is a carrier, Medicare will fund partner testing. Testing the man first is not the default pathway for the three-gene Medicare panel.
• Broader panels exist (speaker mentioned testing “like 900” genes for a donor / comprehensive screening) — technology exists, but Medicare pays for the three common ones.
• Once only. A second claim is rejected (same idea as a karyotype already on file). Pathology labs know if the Medicare item has been claimed; patients often do not remember.
• Guidelines (as stated): offer to anyone trying to conceive or already pregnant. In pregnancy you still have time to screen the partner and, if both are carriers, consider CVS and earlier surgical termination options versus later procedures — “very difficult” conversations, but the opportunity exists.

At-home semen analysis: convenience and caveats

The speaker highlighted a new at-home semen company (ASR captures something like “SAPYEN”). Patients order online; a kit is posted; they collect at home and return it. As spoken:

• Simple analysis about $64; a more complex package around $190 can include DNA fragmentation, antibodies and related tests (figures as spoken — ASR is noisy).
• Cheaper and more practical than attending a lab — especially from regional towns (Lismore example: collecting in a car park, then racing to the lab within an hour so the sample is not left on a shelf).
• Temperature, delay and spillage make clinic samples look falsely low — then you repeat.
• Results go back to the patient.
• Speaker’s claim: validation against an andrologist on a microscope was “very good” / sometimes better; company GM previously at City Fertility; for some regional patients commercial at-home was cheaper than bringing them to the clinic (~$700 vs marriage of travel + appointment friction — ASR garbled).

GPs in the room liked that it takes the burden off the female partner when men resist testing.

Four variables: sperm, tubes, ovulation, timing

Fertility treatment, in the speaker’s framing, is about identifying which variable is broken:

1. Normal sperm (“swimmers”)
2. Open tubes
3. Normal ovulation
4. Sex in the fertile window

The ovulation window is narrow. After the LH surge, the egg is released about 24 hours later. A clinic trigger given at a known time (e.g. 6 pm) produces a predictable release 24 hours later; natural surges can be morning or afternoon, so couples need daily or every-other-day intercourse across the window. Many healthy couples “have no idea where they are in the cycle,” rely on cervical mucus alone, or miss by a day. The speaker has seen patients insist they are ovulating by flow, then a progesterone level shows they are not.

HyCoSy, laparoscopy and endometriosis flush

• HyCoSy is “such a useful thing” — five days of work-up that can confirm tubes and flush / optimise the environment, similar in spirit to treating stage 1–2 endometriosis and flushing tubes in theatre.
• Speaker would not take a patient to theatre only for ovarian drilling for PCOS, but if already operating for something else, drilling / thinning can help stimulation later (analogy: drain an abscess so antibiotics work).
• Without private health cover, theatre cash costs of a few thousand may not be worth it compared with outpatient HyCoSy.

PCOS: metformin, CoQ10 and what not to do

• Metformin guidance (as stated): use when there is metabolic syndrome / metabolic risk factors, not automatically for every “skinny PCOS” patient. Titrate: 500 mg, then BD, then TDS to limit side effects.
• Speaker described a patient who conceived the next month after starting metformin (anecdote).
• CoQ10 300 mg BD for at least two months (paper dose as spoken) before IVF — reduces oxidative stress on eggs; speaker puts patients on it routinely.
• IVF pharmacies can compound DHEA, folic acid dosing, etc. (details garbled).

AMH is a bank balance, not a pregnancy prophecy

The speaker’s analogy: AMH tells you how much is left in the savings account, not whether you can still get pregnant. You can have little in the account and still fall pregnant; PCOS can make AMH look high. Low AMH relative to age often pushes people toward egg freezing, but:

• Many who freeze will never use the eggs — speaker estimated ~70% of egg-freeze patients never “make sense” of using them because they conceive spontaneously.
• Egg freezing is not completely benign (complication anecdote involving another clinic’s cycle).
• Freezing at 34 to use at 39 is different from freezing at 30 to use at 35 — age of the egg matters.
• Interpret hormones on the cycle day they were drawn. Random FSH/LH without cycle context is hard to use. If someone is bleeding daily and has no cycle sense, scan the lining and match biochemically rather than over-ordering panels that mainly generate cost.

GP clinic checklist

1. Offer carrier screening preconception or in early pregnancy; woman first; once only.
2. Get a semen analysis early — at-home kits may help reluctant partners; still interpret abnormal results carefully (delay/temperature).
3. Teach LH timing / consider progesterone to confirm ovulation; don’t assume mucus = ovulation.
4. Refer for HyCoSy when tubes / flush would change management; weigh theatre costs if uninsured.
5. PCOS: metformin for metabolic indication; consider CoQ10 before IVF; avoid unnecessary ovarian drilling.
6. Counsel on AMH as reserve, not destiny; be cautious about rushing to egg freeze without a use-plan.
7. Always interpret FSH/LH/progesterone with cycle day.
