Invitro fertilization process

There are two types of in vitro fertilization (IVF): conventional in vitro fertilization and ICSI (intracytoplasmic sperm injection). The only difference between the two IVF methods is how fertilization is done in the laboratory.

In the case of conventional IVF, the ovum and sperm are placed in the same laboratory dish for their union to occur. In ICSI, on the other hand, a sperm previously selected by the embryologist is introduced into the ovule by microinjection.

In any case, the steps of IVF treatment are as follows:

  1. Ovarian stimulation in women.
  2. Follicular puncture to obtain the ovules.
  3. Semen training in the laboratory.
  4. Fertilization by conventional IVF or ICSI.
  5. Embryo culture in the laboratory.
  6. Transfer of the embryo or embryos of better quality.
