Reciprocal IVF is a fertility treatment that lets both partners in a same-sex female couple play a biological role in creating their child. One partner provides the eggs, and the other carries the pregnancy. It’s sometimes called co-IVF or partner-assisted reproduction, and it follows the same core IVF process used in traditional fertility treatment, with the key difference that two people share the experience rather than one.
How Reciprocal IVF Works
The process has two sides running in parallel. The partner providing eggs goes through ovarian stimulation, taking fertility medications for roughly 10 to 14 days to encourage the ovaries to produce multiple eggs at once. Those eggs are then retrieved in a short outpatient procedure. Meanwhile, the eggs are fertilized with donor sperm in a lab to create embryos.
The other partner, the one who will carry the pregnancy, takes hormonal medications to prepare the uterine lining for implantation. Once an embryo is ready, it’s transferred to her uterus. From that point forward, the pregnancy proceeds like any other. The couple can choose to do a fresh transfer (placing the embryo shortly after fertilization) or freeze the embryos and do a frozen embryo transfer at a later date, which gives more flexibility with timing.
Before any of this begins, both partners undergo a full medical and reproductive evaluation. The egg provider will have an ultrasound to assess ovarian reserve and blood work to measure key hormone levels. The carrying partner will have a uterine evaluation to confirm her uterus can support a pregnancy. These screenings help the fertility clinic determine which partner is best suited for each role, though many couples come in already knowing who wants to do what.
Choosing and Screening Donor Sperm
Since reciprocal IVF requires sperm from a third party, couples select a donor through a licensed sperm bank. The FDA requires extensive screening for all tissue donors, including sperm donors. Every donor is tested for HIV (types 1 and 2), hepatitis B and C, syphilis, HTLV, and cytomegalovirus. Donors are also screened for sexually transmitted infections like chlamydia and gonorrhea, along with a full review of their medical history for communicable disease risk factors.
Most sperm banks go beyond these minimums with additional genetic carrier screening. Couples typically choose a donor based on physical characteristics, health history, education, and sometimes personality profiles or audio interviews the bank provides.
Success Rates by Age
The success of reciprocal IVF depends primarily on the age of the partner providing the eggs, not the age of the partner carrying the pregnancy. Egg quality is the biggest variable in any IVF cycle, and it declines with age. According to the American Pregnancy Association, live birth rates per IVF cycle break down roughly as follows:
- Under 35: 41 to 43 percent
- 35 to 37: 33 to 36 percent
- 38 to 40: 23 to 27 percent
- Over 40: 13 to 18 percent
This is one reason some couples choose to have the younger partner provide eggs, even if the older partner also has good ovarian reserve. That said, the carrying partner’s uterine health matters too. A well-prepared uterine lining is essential for implantation, and conditions like fibroids or polyps can affect outcomes regardless of egg quality.
What It Costs
In the United States, a single reciprocal IVF cycle typically runs between $20,000 and $30,000. That range covers clinic fees, monitoring for both partners, ovarian stimulation medications, egg retrieval, fertilization, and embryo transfer. If frozen embryo transfer is needed instead of a fresh transfer, that adds roughly $5,000 at most clinics.
Costs vary significantly by region and provider. Some lower-cost clinics advertise complete reciprocal IVF cycles starting around $8,000 to $10,000, though these are outliers. Donor sperm adds another $500 to $1,500 per vial depending on the bank, and most clinics recommend purchasing at least two vials. Legal fees for parentage agreements, discussed below, can add $2,000 to $5,000 on top of the medical costs. Many clinics offer payment plans, and some insurance plans now cover portions of IVF for same-sex couples, though coverage is far from universal.
Medical Risks for Each Partner
The two partners face different sets of risks because they go through different parts of the process.
For the egg provider, the primary concern is ovarian hyperstimulation syndrome (OHSS), a reaction to fertility medications where the ovaries swell and leak fluid into the abdomen. Mild cases involve bloating and discomfort that resolves on its own. Severe cases, which are less common, can cause significant abdominal swelling, nausea, difficulty breathing, and in rare instances require hospitalization. About one in four patients who develop OHSS need a procedure to drain excess fluid, and those hospitalized stay an average of four to five days. Modern protocols have made severe OHSS increasingly rare, and most clinics monitor closely during stimulation to adjust medication doses.
For the carrying partner, the risks are those associated with any IVF pregnancy: a slightly higher chance of preterm delivery and lower birth weight compared to spontaneous conception. These risks are modest and are managed through standard prenatal care.
Legal Parentage
Biology alone does not guarantee legal parentage. In reciprocal IVF, the birth certificate will typically list the partner who delivers the baby. The other partner, even though she provided the egg, may need to go through second-parent adoption to be legally recognized as a parent. This varies by state. Some states allow pre-birth orders that establish both parents’ rights before delivery, while others require a post-birth adoption process.
Working with a family law attorney who specializes in assisted reproduction is a practical necessity, not a precaution. Parentage laws are inconsistent across the U.S., and having the right legal documents in place protects both partners and the child. Most fertility clinics can refer couples to attorneys experienced in this area.
Reciprocal IVF for Trans and Non-Binary People
Reciprocal IVF is not limited to cisgender female couples. Trans men and non-binary individuals who have retained their ovaries or uterus can also participate. A key question for people on testosterone therapy is whether they need to stop hormones before providing eggs or carrying a pregnancy.
Traditionally, patients were asked to discontinue testosterone for several months before ovarian stimulation. However, a published case report documented successful egg retrieval and reciprocal IVF in a 26-year-old trans man who had been on testosterone for four years and remained on it throughout the stimulation process. The eggs were frozen, later thawed, and used in a reciprocal IVF cycle with his cisgender female partner. This is a newer approach, and protocols vary between clinics, but it represents a shift toward more flexible care that doesn’t require patients to pause gender-affirming hormone therapy.
Why Couples Choose Reciprocal IVF
The biggest draw is shared biological involvement. In standard IVF with donor sperm, one partner does everything: provides the eggs, carries the pregnancy, and delivers the baby. The other partner has no physical connection to the process. Reciprocal IVF changes that equation. One partner contributes genetically, the other carries and gives birth, and both can feel they played an irreplaceable role.
It is more expensive and more medically involved than intrauterine insemination (IUI), which is the simpler and cheaper first-line option for many same-sex female couples. IUI involves placing donor sperm directly into the uterus of one partner during ovulation, with no egg retrieval or embryo transfer. Some couples start with IUI and move to reciprocal IVF after unsuccessful attempts, while others choose reciprocal IVF from the start because the shared experience matters to them. Neither approach is better in absolute terms. The right choice depends on each couple’s priorities, budget, and fertility profile.
