Reciprocal IVF: One partner’s eggs, the other’s pregnancy

Reciprocal IVF lets two women share the journey: one partner provides the eggs, the other carries the pregnancy. It uses established IVF protocols and is easy to plan and well documented—medically, organisationally and legally. For accessible overviews of process and success drivers, see the HFEA (HFEA); for clinical depth, see NICE (CG156), ESHRE (Guidelines) and the Government of Canada/NHS patient pages (Health Canada, NHS).

Decision first

Before appointments and medicines, decide roles: who donates, who carries—and why. Key inputs are egg age and findings, day-to-day practicality, and your shared preference. A simple decision matrix helps:

CriterionQuestions to assessPractical tip
Egg factorsAge, AMH/AFC, endometriosis, previous surgeryAlign roles with egg age
Uterine factorsLining, fibroids/polyps, inflammationAddress issues before starting
Work & lifeWork hours, shifts, care supportShare calendars and plan cover
Preference & rolesWho prefers to donate, who to carry—now & later?Discuss expectations openly

How reciprocal IVF works

Partner A’s eggs are stimulated and collected, fertilised in the lab with donor sperm, and the embryo is transferred to Partner B’s uterus. A contributes the genetics, B the pregnancy. For a future sibling, you can intentionally swap roles. The clinical pathway mirrors IVF; the main differences are role allocation, documentation and legal steps.

Success rates and factors

The strongest lever is the egg age of the donating partner. Other drivers include lab quality, embryo development, endometrial preparation, transfer timing, a single-embryo strategy, and co-existing conditions. Professional bodies often recommend single-embryo transfer to reduce multiple pregnancy risks—reflected in ESHRE stimulation guidance and everyday clinical practice (ESHRE).

FactorImpactWhat to do
Egg agehighUse age & AMH/AFC to inform role choice
Embryo qualitymoderate–highChoose an experienced lab; use add-ons only with proven benefit (ASRM)
EndometriummoderateTreat inflammation/fibroids; hit the transfer window
Transfer strategymoderateUsually single-embryo transfer; weigh risks carefully
LifestylemoderateDon’t smoke; prioritise sleep, nutrition and stress care

For donation standards and add-ons, the ASRM guidance is a clear benchmark (ASRM). For a plain-language overview of causes and care pathways, see PregnancyInfo.ca (SOGC) and the NHS.

Step-by-step

  1. Pre-assessment for both: History, ultrasound, hormones, ovarian reserve (AMH/AFC), infection screening, vaccination review; genetic counselling if needed. Set roles, timeline and budget; select a clinic.

  2. Ovarian stimulation and egg collection (Partner A): Stimulation with monitoring, trigger, transvaginal collection. Aim: good yield with a low OHSS risk.

  3. Fertilisation and embryo culture: IVF/ICSI depending on findings, culture over several days, quality grading. Use add-ons only where benefit is evidenced.

  4. Preparing for transfer (Partner B): Lining preparation in a natural or substituted cycle; define the transfer window; usually single-embryo transfer.

  5. Transfer and follow-up: Embryo transfer, luteal support, pregnancy test, early scan; adjust medicines where needed.

Safety, tests and medicines

Standard care includes up-to-date infection screening, vaccination status (e.g. rubella), medicine and thyroid checks, and folic acid pre-conception. Modern protocols reduce OHSS risk; single-embryo strategies cut multiple pregnancy risk. Core principles are consistent across guidelines (see ESHRE and PregnancyInfo.ca).

Time, costs and organisation

Expect waits for the first appointment and diagnostics. The active phase typically spans two to six weeks—from stimulation through collection and culture to transfer. Costs and funding vary widely across provinces and insurance plans; plan headroom for extra cycles or frozen transfers and keep documents centralised.

AppointmentsMonitoring, procedure day, transfer window, time off workShared calendar; arrange cover early
BudgetStimulation, collection, lab, transfer, medicines; possible freezing & storageRequest itemised quotes; add contingency
DocumentsConsents, donor papers, invoices, protocolsScan and store centrally for the long term
LogisticsTravel, childcare, day-to-day supportUse checklists; define responsibilities

Choosing a donor

You may use a clinic/sperm-bank donor or a known donor. Prioritise current testing, transparent profiles, clarity on future contact, and robust documentation. If you plan siblings, discuss same-donor availability and family limits early. Clinic pathways provide quality control and traceability; if considering private routes, structured agreements and legal advice are essential.

Myths and facts

  • More embryos mean higher chances? Single-embryo transfer reduces risk and is often the safer strategy.
  • The fitter partner should carry? Egg age, medical history, daily life and preference matter more.
  • Add-ons always help? Only use those with proven benefit.
  • Law is the same everywhere? Rules differ by country—and in Canada, some details differ by province.
  • Fresh beats frozen? Frozen transfers can perform just as well.
  • Lifestyle cancels out age? Healthy habits help but don’t replace biology.
  • A known donor makes everything simpler? Testing, documentation and clear agreements remain essential.
  • One negative transfer means the plan was wrong? Several attempts are common; protocols can be adjusted.

When to see a doctor

  • Before starting: baseline assessments plus role and timeline planning.
  • If you have existing conditions, take regular medicines or have cycle irregularities.
  • If pregnancy doesn’t occur after transfers or protocols need changing.

Conclusion

Reciprocal IVF combines shared involvement with the structure of clinical care. What matters most: egg age, a well-prepared endometrium, realistic time and budget plans, evidence-based choices and the right legal paperwork for your province. Careful planning creates good conditions for a safe course—now and for future siblings.

Frequently Asked Questions (FAQ)

One partner donates eggs; the other has the embryo transfer and carries the pregnancy—both partners are involved.

Yes. Both terms describe shared genetic and gestational involvement within the couple.

The technique is possible, but success strongly depends on the egg age of the donating partner.

Often sensible due to egg quality, but individual findings can change the role decision.

Both can be comparable; the choice depends on protocol and individual factors.

Single-embryo transfer is usually recommended to reduce risks from multiple pregnancy.

Infection screening, vaccination review, hormone and ultrasound checks; genetic counselling and thyroid tests where appropriate.

The active phase is usually two to six weeks, plus waiting time for appointments and diagnostics.

Possible side-effects from stimulation and procedures, and risks from multiple pregnancy; modern protocols reduce these.

Yes—many couples plan a sibling with roles reversed, depending on age and findings.

No. Clinics and licensed sperm banks provide screened donors and clear documentation.

Often yes, subject to availability and family limits; plan with your clinic early.

Costs vary by province, clinic and protocol; expect additional spend for medicines, lab work and storage.

Use a shared calendar, scan documents, and store them centrally; define checklists and responsibilities.

Assisted reproduction is regulated federally by the Assisted Human Reproduction Act and Health Canada’s Safety of Sperm and Ova Regulations. The birth mother is a legal parent; recognition of the non-birth parent follows provincial/territorial parentage laws using clinic consent forms—speak to your clinic or a local family-law professional for your province.
