Reciprocal IVF — also called co-IVF, partner IVF, or reception of oocytes from partner (ROPA) — is a form of IVF in which one partner (Partner A) provides the eggs, and the other partner (Partner B) carries the resulting pregnancy. The child has a genetic connection to Partner A and a gestational/birth connection to Partner B.
For lesbian couples, reciprocal IVF is a meaningful option because it allows both partners to be biologically involved in their child's conception — one as the genetic contributor, one as the person who grows and births the baby. Understanding what the process involves, how success rates compare to standard IVF, what it costs, and how to protect both partners' legal parental rights is essential before deciding whether this path is right for you.
Who Is Reciprocal IVF For?
Reciprocal IVF is specifically designed for cisgender lesbian couples (two women, both with functional reproductive anatomy). It is also relevant for some transgender and nonbinary couples, depending on individual anatomy and transition history.
The key prerequisites:
- Partner A (egg provider) has adequate ovarian reserve and can undergo ovarian stimulation and egg retrieval
- Partner B (carrier) has a functional uterus and can carry a pregnancy safely
- Both partners are in good general health
If both partners could potentially carry, the decision of who provides eggs vs who carries is typically guided by:
- Age (eggs from the younger partner tend to yield better outcomes)
- Ovarian reserve testing results (AMH, AFC)
- Uterine health
- Personal preference and emotional considerations
How Reciprocal IVF Works: Step-by-Step
Step 1: Initial Evaluation of Both Partners
Both Partner A and Partner B undergo fertility evaluations:
Partner A (egg provider):
- Ovarian reserve assessment: AMH blood test + antral follicle count (AFC) via transvaginal ultrasound
- Hormone panel: FSH, estradiol, LH
- Expanded genetic carrier screening
- Infectious disease testing (FDA-required)
- General health review
Partner B (carrier):
- Uterine anatomy evaluation (often via hysteroscopy or saline sonogram)
- Hormone panel
- Infectious disease testing
- General health assessment
- If indicated, a mock embryo transfer to assess uterine anatomy and transfer technique
Step 2: Partner A's Ovarian Stimulation Cycle
Partner A undergoes a standard IVF stimulation cycle:
- Baseline ultrasound and bloodwork (Day 2-3 of cycle)
- Ovarian suppression (optional — depends on protocol; some use BCP or GnRH antagonist)
- Injectable gonadotropins for 8-12 days (subcutaneous injections, daily)
- Monitoring appointments every 2-3 days (ultrasound + bloodwork)
- Trigger shot when follicles are mature
- Egg retrieval under IV sedation, 36 hours post-trigger
Step 3: Fertilization with Donor Sperm
Eggs retrieved from Partner A are fertilized with sperm from a previously selected donor. The couple will have selected a sperm donor in advance — an open-identity donor is generally recommended based on research supporting access to origins information.
Fertilization is typically performed via ICSI (intracytoplasmic sperm injection) to maximize fertilization rates. Embryos are cultured to blastocyst stage (Day 5-6).
Step 4: PGT-A Testing (Optional but Recommended)
Preimplantation genetic testing for aneuploidies (PGT-A) can be performed on blastocysts before transfer. This identifies chromosomally normal (euploid) embryos. PGT-A is particularly valuable if:
- Partner A is 35 or older
- There is a history of miscarriage
- The couple wants to maximize per-transfer success probability
If Partner A is younger (under 32), the benefit of PGT-A is less clear, as the background rate of chromosomal abnormalities is already low.
Step 5: Partner B's Endometrial Preparation
While Partner A undergoes stimulation (or in a subsequent cycle for frozen embryo transfer), Partner B prepares her uterine lining:
- Estrogen supplementation for 12-14 days (oral tablets, patches, or injections)
- Monitoring via ultrasound to confirm lining development (target 7mm+ trilaminar pattern)
- Progesterone addition when lining is ready (5-6 days before blastocyst transfer)
Step 6: Embryo Transfer to Partner B
One (or occasionally two, after discussion of twin risk) euploid blastocyst is transferred to Partner B's uterus in a brief outpatient procedure. Partner B remains on progesterone supplementation for 10-12 weeks if pregnancy is confirmed.
Step 7: Pregnancy Confirmation and OB Transition
Beta hCG blood tests at 10-14 days confirm pregnancy. Repeat beta and early ultrasound at 6-7 weeks confirm intrauterine pregnancy and fetal heartbeat. Care transitions to Partner B's OB or midwife.
Considering Conception at Home?
Some couples try at-home insemination with donor sperm before moving to more involved clinical protocols like reciprocal IVF — particularly if either partner has no identified fertility concerns.
MakeAMom makes reusable at-home insemination kits for individuals and couples trying to conceive outside a clinic — including those using donor sperm. The CryoBaby kit is specifically designed for frozen sperm, which is the format most sperm banks ship in.

Success Rates for Reciprocal IVF
Reciprocal IVF success rates follow the same logic as standard IVF with donor eggs: the relevant age for success rates is the egg provider (Partner A), not the carrier (Partner B).
This means:
- If Partner A is 30, success rates reflect a 30-year-old's egg quality
- If Partner A is 38, success rates reflect a 38-year-old's egg quality
- Partner B's age has a smaller impact on outcomes (primarily through uterine receptivity factors)
CDC Data on Reciprocal IVF
CDC ART Surveillance data reports outcomes for "IVF using a fresh embryo transfer with partner/spouse eggs (not patient's own eggs)," which captures reciprocal IVF arrangements. These outcomes align closely with own-egg IVF success rates stratified by the egg provider's age:
| Partner A Age | Live Birth Rate per Transfer |
|---|---|
| Under 35 | ~45-50% |
| 35-37 | ~35-42% |
| 38-40 | ~25-35% |
| 41-42 | ~15-22% |
| Over 42 | ~5-15% |
These rates are lower than donor egg IVF rates (which use young donors' eggs) but comparable to standard own-egg IVF using the egg provider's age as the reference. Frozen embryo transfers have shown equivalent or slightly superior outcomes to fresh in recent years.
The implication for partner selection: If there is a significant age difference between partners, using the younger partner's eggs yields better statistical outcomes regardless of who carries. This is a purely medical consideration, and many couples weigh emotional and relational factors alongside statistics.
Legal Considerations: Protecting Both Partners' Parental Rights
This is a critical area where couples must act proactively. Both partners are the child's parents — but the law does not automatically recognize both parents in all states.
The Challenge
- Partner A is the genetic parent (provided the eggs)
- Partner B is the gestational parent (carried and birthed the child)
- Neither of these automatically makes both partners the legal parent in all US states
Without legal action, there is a risk that the non-birth parent (in some jurisdictions, the non-gestational parent) is not legally recognized as a parent.
Pre-Birth Orders
In states that allow pre-birth orders for same-sex couples (California, Nevada, Washington, Colorado, Connecticut, New Jersey, New York, and others), both partners can be named as legal parents on the birth certificate before the child is born. This is the gold standard.
Second-Parent Adoption
In states that do not issue pre-birth orders covering both partners, the non-birth parent may need to complete a second-parent adoption to be legally recognized as a parent. This process can take weeks to months and involves court proceedings — but it is well-established and widely available.
Joint Birth Certificate
In states with strong same-sex parenting protections, both partners can be named on the birth certificate directly, without additional proceedings.
States with Best Legal Protections for LGBTQ+ Families
States with the strongest protections for same-sex couples in reciprocal IVF:
| State | Available Protections |
|---|---|
| California | Pre-birth order for both partners; both on birth certificate |
| Nevada | Pre-birth order available |
| Washington | Pre-birth order available |
| Colorado | Pre-birth order available |
| Connecticut | Pre-birth order available |
| New Jersey | Pre-birth order available |
| New York | Strong same-sex family law; access to pre-birth orders |
| Massachusetts | Strong protections; second-parent adoption well established |
Federal Protections
Obergefell v. Hodges (2015) established same-sex couples' constitutional right to marry. Pavan v. Smith (2017) confirmed that states must list same-sex spouses on birth certificates on the same terms as opposite-sex spouses. However, the specific application to non-gestational parents in reciprocal IVF arrangements still requires state-level attention — do not assume federal marriage equality automatically resolves all parental recognition issues.
A reproductive attorney in your state is essential before beginning a reciprocal IVF cycle.
Emotional and Relationship Dimensions
Reciprocal IVF uniquely involves both partners in biological ways that can be emotionally significant — and sometimes complex.
Processing Role Differentiation
While many couples find the shared biology of reciprocal IVF meaningful and bonding, it's worth acknowledging that the roles are different. Partner A goes through ovarian stimulation, injections, egg retrieval, and the physical demands of that process. Partner B carries the pregnancy and gives birth. These experiences are profoundly different, and couples who discuss their expectations, feelings, and concerns in advance — ideally with a counselor experienced in LGBTQ+ family building — tend to navigate the process with more resilience.
If the First Partner Doesn't Want to Provide Eggs
Some couples decide that one partner carries the first pregnancy and the other provides eggs for logistical or personal reasons — but then want to consider a "swap" for a second child (the carrier becomes the egg provider, and the egg provider becomes the carrier). This is sometimes called "reciprocal IVF in reverse" for the second child. Clinically it's the same process; emotionally, it can create a sense of balance and shared contribution across the family.
Sperm Donor Selection as a Shared Decision
Selecting a sperm donor is a significant shared decision. Many reciprocal IVF couples prefer open-identity donors — both because research supports disclosure, and because it gives the child access to information about one genetic contributor (the partner who provided eggs is the other). Discussing donor selection criteria together — and your individual weighting of physical traits, medical history, identity options — is part of the shared process.
Cost: Reciprocal IVF vs Standard IVF
Reciprocal IVF costs modestly more than standard IVF because two full fertility evaluations are required (for both partners) rather than one:
| Cost Component | Standard IVF (one patient) | Reciprocal IVF |
|---|---|---|
| Partner A evaluation | ~$500-$1,500 | ~$500-$1,500 |
| Partner B evaluation | — | ~$500-$1,500 |
| Stimulation medications | $3,000-$7,000 | $3,000-$7,000 |
| Egg retrieval + lab | $5,000-$10,000 | $5,000-$10,000 |
| Embryo transfer | $2,000-$4,000 | $2,000-$4,000 |
| PGT-A (optional) | $3,000-$6,000 | $3,000-$6,000 |
| Sperm (donor vials) | $500-$2,000 | $500-$2,000 |
| Total (before insurance) | $14,000-$32,000 | $15,000-$34,000 |
The incremental cost of the second evaluation is modest (~$500-$1,500). Most of the base IVF costs are the same.
Insurance Coverage
IVF insurance coverage varies by state and employer plan. Some states mandate fertility coverage but specifically exclude same-sex couples in their mandate language (which is legally challenged in several states). The Human Rights Campaign's Healthcare Equality Index provides guidance on which employers and healthcare systems are most likely to cover reciprocal IVF with equity.
When reviewing insurance coverage:
- Ask specifically whether "partner egg recipient cycle" or "co-IVF" is covered
- Verify that the stimulation/retrieval for the egg provider (Partner A) and the transfer cycle for the carrier (Partner B) are both covered
- Some plans will cover one partner's treatment but not the other's — this requires careful verification
Key Takeaways

- Success rates are determined by the egg provider's age — using the younger partner's eggs improves outcomes
- Both partners' parental rights must be legally established — pre-birth orders are available in many states
- States with strongest LGBTQ+ legal protections (California, Nevada, Washington, Colorado) are ideal
- Costs are similar to standard IVF ($15,000-$34,000 per cycle), with modest incremental cost for dual evaluations
- Open-identity sperm donors are recommended; donor selection is a shared decision
- Psychological preparation and counseling support both partners through role differentiation

Frequently Asked Questions
Q: How does reciprocal IVF work, and how is it different from standard IVF? A: In reciprocal IVF, one partner (Partner A) undergoes ovarian stimulation and egg retrieval, those eggs are fertilized with donor sperm, and the resulting embryo is transferred to the other partner (Partner B) who carries the pregnancy. Standard IVF uses one person's eggs and that same person carries the pregnancy. Reciprocal IVF allows both partners to have a biological connection — one genetic, one gestational — to their child.
Q: Which partner's age determines reciprocal IVF success rates? A: Success rates are determined by the egg provider's (Partner A's) age — not the carrier's. If Partner A is 30, success rates reflect a 30-year-old's egg quality (approximately 45–50% per transfer). If Partner A is 38, success rates reflect a 38-year-old's egg quality (approximately 25–35% per transfer). Partner B's age has a smaller impact, primarily through uterine receptivity factors. If there is a significant age difference between partners, using the younger partner's eggs yields better statistical outcomes.
Q: Are both partners automatically recognized as legal parents in reciprocal IVF? A: Not automatically in all states. Partner A (genetic parent) and Partner B (gestational/birth parent) are both the child's parents, but legal recognition requires proactive steps. In states that allow pre-birth orders for same-sex couples (California, Nevada, Washington, Colorado, Connecticut, New Jersey, New York, and others), both partners can be named on the birth certificate before birth. In other states, second-parent adoption may be required. A reproductive attorney in your state is essential before beginning.
Q: How much more does reciprocal IVF cost compared to standard IVF? A: The incremental cost is modest — approximately $500–$1,500 for the second partner's fertility evaluation. Most other costs are the same: stimulation medications ($3,000–$7,000), egg retrieval and lab ($5,000–$10,000), embryo transfer ($2,000–$4,000), and donor sperm ($500–$2,000). Total estimated cost is $15,000–$34,000 per cycle, compared to $14,000–$32,000 for standard IVF.
Q: What sperm donor considerations apply to reciprocal IVF? A: Open-identity donors are generally recommended — research supports disclosure to donor-conceived children, and selecting an open-identity donor gives the child the option (but not obligation) to seek out their biological origins at 18. Sperm donor selection in reciprocal IVF is a shared decision, and many couples discuss their weighting of health history, identity options, and other profile criteria together before choosing.
