In Vitro Fertilization

Technique in which the egg and sperm are joined in the laboratory to fertilize them and subsequently transfer the embryos.

ROPA Method

In vitro fertilization technique that allows a couple of women to participate: one donating the eggs and the other carrying the pregnancy.

Egg donation

Technique in which an egg donor is used due to a very low ovarian reserve. It can be fertilized with partner or donor sperm.


Time Lapse

It consists of an incubator with a built-in camera and a photographic system that helps to choose the most suitable embryo.

Seminal Studies

Biologists study the semen sample in the laboratory to perform tests such as: FISH, fragmentation or Fertile chip.


When we talk about blastocyst culture, we refer to the time an embryo spends in the laboratory. This is for at least 5 days.
