In Vitro Fertilization

Fertilização In-Vitro

Classic In Vitro Fertilization (IVF)

Known worldwide as “test-tube baby”, IVF is a technique widely used for the treatment of infertility. To perform IVF, the couple must go through certain phases of treatment.

Ovarian stimulation-based drugs occur in the first stage of treatment in order to obtain a greater number of oocytes to increase the chances of fertilization and pregnancy. We then use the human chorionic gonadotropin (HCG) hormone to trigger the maturation of the oocytes, which are extracted from the ovaries and then identified and selected to join with sperm in a culture in vitro. Once formed, the embryos are placed in a greenhouse, whose environmental conditions are similar to the fallopian tube, usually for 72 hours (between 48 and 120 hours), when they reach about eight or more cells. There, those who submit the best quality scores will be transferred to the womb, already prepared to receive them.

In Vitro Fertilization (IVF) by ICSI

ICSI stands for Intra Cytoplasmic Sperm Injection. In this technique, the sperm is introduced into a mature oocyte through a microscopic injection. The technique is considered the second major milestone in the history of the science of Assisted Human Reproduction, after the birth of the first baby using IVF. The technique is used especially in cases of severe male infertility, where sperm production is small, rare or practically nil. Once the oocyte is fertilized by sperm injection and the embryo is formed, the procedure is similar to the classical IVF.
