ROPA METHOD

The ROPA Method, which stands for Reception of Oocytes from the Partner, is designed for a couple of two women who both want to actively participate in Assisted Reproduction treatment, specifically in In Vitro Fertilization (IVF).

One of the partners in the ROPA method donates the eggs. Ovarian stimulation is tailored to the assessment and response of the partner providing the eggs. The clinical team individualizes medication, duration and monitoring; there is no single schedule for every couple. Source: ESHRE, ovarian stimulation (2025). Ultrasound monitoring tracks follicular growth (each follicle contains an egg), and once the eggs are mature, a follicular aspiration is performed. The eggs are then fertilized in our assisted reproduction laboratory using a previously selected sperm sample, either from a donor or a sperm bank (domestic or international). The embryos are cultured for a period of 5 to 7 days. PGT may be considered for a defined genetic question: PGT-A assesses chromosome number, PGT-M a specific familial variant, and PGT-SR imbalances associated with structural rearrangements. It is not automatically indicated for every couple; benefits, limitations and alternatives must be discussed, and it cannot guarantee an embryo free of every condition.

The other partner in the ROPA method receives the embryo and carries the pregnancy. Endometrial preparation, medication and monitoring are tailored to the individual assessment. Transfer timing and the number of embryos are decided with the specialist, considering prognosis and prioritizing single-embryo transfer to reduce the risk of multiple pregnancy. Having two embryos available does not mean that both should be transferred. Source: ESHRE, number of embryos to transfer (2023 guideline; 2024 summary).

In the ROPA method, one partner may provide the eggs and the other may carry the pregnancy after individual assessment. Care at ViaFERT is coordinated with informed consent and a plan tailored to the reproductive role and medical needs of each partner; the method does not guarantee pregnancy or live birth.

RECIPROCAL IVF · DIRECT ANSWERS

Reciprocal IVF questions to resolve before treatment

How is reciprocal IVF different from egg donation?

In reciprocal IVF, one intended parent provides the eggs and the other may carry the pregnancy. Donation screening and legal classification can differ by jurisdiction, so the gamete source and consent pathway must be documented clearly.

Do both partners need an individual evaluation?

Yes. The egg provider needs an ovarian and medical assessment, while the partner considering pregnancy needs a uterine, obstetric and general health review appropriate to the case.

What factors influence the chance of success?

Relevant factors include the egg provider’s age and ovarian response, the sperm source, embryo development, uterine factors and previous reproductive history. A general rate does not replace an individual prognosis.

Can international patients begin planning remotely?

Records and previous studies may be reviewed to organize the first steps, but monitoring, procedures, travel and the correct ViaFERT location must be confirmed in an individual plan.

CLINICAL INFORMATION

ROPA method or reciprocal IVF: the short answer

ViaFERT · Sinaloa

What it is

An IVF pathway in which one partner provides the eggs and the other may carry the pregnancy after embryo creation, provided that both individual assessments support the plan.

What shapes the recommendation

Each partner needs an individual assessment; the sperm source, applicable testing, consent and independent legal advice should also be clarified when relevant.

Important limit

Genetic and gestational participation does not guarantee an outcome; prognosis depends on factors including the egg provider’s age, ovarian response, embryos and the uterine environment.
