IVF: In Vitro Fertilization
Thanks to in vitro fertilization, we manage to fertilize the eggs (oocytes) with sperm from your partner or a donor outside the mother’s uterus, under laboratory conditions.
What is IVF?
In Vitro Fertilization (IVF) is an assisted reproduction technique that involves the fertilization of the oocyte (egg) by the sperm under in vitro culture conditions in the laboratory, that is, outside the female reproductive system.
It is an assisted reproduction technique needed in cases of female or male infertility or in assisted reproduction techniques such as the ROPA Method for LGBTQ couples.
In which cases is IVF indicated?
IVF indications for infertility:
- Tubal factor: absence, obstruction, or damage to the fallopian tubes.
- Endometriosis.
- Male factor (alteration in sperm concentration, motility, or morphology).
- Unexplained infertility.
- Failure of less aggressive treatments: ovulation induction, artificial insemination.
- Decreased ovarian reserve.
- Immunological disorders.
IVF indications in the absence of infertility:
- Preimplantation Genetic Testing (PGT), in order to identify and discard affected embryos.
- Fertility preservation.
- Serodiscordant couples: a couple where one member has a chronic sexually transmitted disease that prevents, due to the risk of transmission, achieving pregnancy naturally.

In Vitro Fertilization Process
1. Request your first free visit
- Visit with an expert doctor in Assisted Reproduction.
- Fertility Study where we perform an ultrasound to evaluate the egg reserve and a semen analysis.
- Medical visit for results and diagnostic guidance.

2. Hormonal control and stimulation
The start of the in vitro fertilization treatment is marked by the woman’s menstrual cycle. At this point, ovarian stimulation begins.
The stimulation protocol (type of hormones and dosage) will be individualized and will be determined mainly by age, ovarian reserve, body mass index, and response to previous stimulations.

3. Follicular puncture
The follicular puncture is a simple surgical procedure performed on an outpatient basis with local anesthesia or short-duration general anesthesia (intravenous sedation), after which the patient will remain under observation for a variable period of time, usually ranging from 2 to 4 hours.
4. Egg fertilization and embryo culture
There are 2 techniques to bring the oocytes into contact with the sperm: conventional IVF (which involves putting about 100,000 good motility sperm in contact with an oocyte, producing a natural selection of the sperm) or microinjecting a sperm with good motility into each mature oocyte (ICSI).

5. Embryo transfer
Finally, we will proceed to the transfer of the embryo(s) to the maternal uterus vaginally. The embryo transfer will be performed on the 2nd-3rd or 4th-5th day after the follicular puncture, choosing the best embryo(s).
After insemination, the woman can continue with her normal daily activity. Strict rest is not necessary after this procedure, although it is advisable to avoid physical exercises considered risky.
The embryos are deposited in the uterine cavity under ultrasound guidance. It is an outpatient procedure that does not require anesthesia or admission.
