Is Gonal the same as Ovitrelle?

By Dr. María Arqué.
Last Update: 06/25/2020

No. Gonal and Ovitrelle are drugs used in assisted reproduction treatments with different functions and different mechanisms of action.

Gonal consists of recombinant FSH (follitropin alpha) and is used to stimulate the growth of follicles during ovarian stimulation. Ovitrelle is a drug that contains the recombinant hCG hormone (r-hCG) and is used in the vast majority of assisted reproduction treatments. It consists of a single injection that succeeds in triggering the final follicular maturation after controlled ovarian stimulation, both in artificial insemination (AI) and in vitro fertilization (IVF).

In particular, Ovitrelle performs the following actions on the woman's body:

  • It promotes the recovery of oocyte meiosis and thus induces the final maturation of the follicles that have developed in ovarian stimulation.
  • It allows ovulation (exit of mature eggs from the ovary) in artificial insemination cycles or reports programmed so that fertilization can take place.
  • It activates the formation of the corpus luteum in the ovary, which secretes the oestradiol and progesterone necessary for the endometrium to become receptive and embryonic implantation.
