Assisted reproduction techniques

ROPA (Egg Reception from partner)

ROPA or co-maternity is a variant of in vitro fertilization (IVF) through which both women of a female couple whom decide to have a baby together, are able to share the process of pregnancy.

Both women are involved actively in the process and are biological mothers, one provides her eggs and the other receives the embryos and carries the pregnancy. One is the genetic mother (donate her eggs) and the other is the pregnant woman (got pregnant).

ROPA. Steps of the process

The assisted reproduction technique performed is an in vitro fertilization with donor sperm, but in this case, the female couple shares the different parts of the treatment:

Genetic mother (eggs)

She undergoes ovarian stimulation and egg collection.

Eggs are inseminated and fertilized in the ivf laboratory using the sperm from an anonymous donor. The resulting embryos are cultured in optimal conditions within the incubator between 3 and 5 days.

The embryo development is monitored “in vitro” to identify the ones with the highest quality.

Pregnant mother

The selected embryo is transferred into the uterus of the recipient woman who will carry the pregnancy.

She undergoes endometrial preparation with oestrogens and once the endometrium (inner layer of the uterus) is ready for the implantation, the embryo is transferred into the uterus of the recipient woman (pregnant mother).
