Why IVF in Spain
In vitro Fertilization is a procedure where a woman’s eggs are put in contact with her partner’s sperm or donor sperm in a lab, with the objective of obtaining embryos to transfer to the woman’s uterus to achieve pregnancy. There are many reasons why IVF is carried out: failure to achieve pregnancy with artificial insemination, in women over 37 years of age, bilateral obstruction of the Fallopian tubes, or failure to achieve pregnancy because of the sperm.
IVF abroad is a great solution. IVF in Spain is possible thanks to Procreatec,
IVF can be divided into 4 phases:
- Ovarian stimulation: meds are administered by subcutaneous injection (which the patient can give herself) to stimulate the ovaries. The medication will help increase the number of follicles that mature during the cycle. Serial ultrasound checks will be made in order to adjust the necessary dose of medication during ovarian stimulation and to record how the follicles are growing. In each follicle there is one egg. Once the follicles have reached the suitable size, an injection of hCG is administered and 36 hours later egg retrieval is performed to extract the eggs.
- Egg retrieval: the goal of the retrieval is to extract mature eggs from the ovaries. The egg retrieval is performed through the vagina and the patient is sedated so that she feels no pain or discomfort.
- Fertilization in the laboratory: eggs can be fertilized in 2 different ways: by conventional IVF or by microinjection of the sperm.
- Conventional IVF: the ova are placed in a culture plate and are surrounded by capacitated sperm. After waiting 18-22 hours, fertilization is checked.
- Sperm microinjection: This process is also known as Intracytoplasmatic Sperm Injection (ICSI). This is a technique where a live spermatozoon is injected into an egg. ICSI is used when there is a low sperm count or when there is poor morphology or low motility of the sperm. The results of this method in attaining fertilization are excellent.Follow-up has been made on thousands of children conceived by ICSI and the technique has been proved safe. In some kinds of sterility, there may be a slight increase in fetal anomalies related to a genetic cause. However, in other cases, there is no difference in ICSI children compared to a population of children born from spontaneous pregnancies.
The goal is to achieve a singleton pregnancy but depending on the age of the patient and the embryo quality, the patient and the doctor will decide on how many embryos to transfer.
Risks of IVF
Ovarian hyperstimulation syndrome is an exaggerated response to the stimulation treatment. It can be mild, moderate or severe. Using the correct dosage of medication prevents hyperstimulation although some patients are so hypersensitive to the hormones used in ovarian stimulation and even with a very low dosage they develop too many follicles. In this case, to prevent full-blown symptoms of hyperstimulation, the cycle is cancelled and hCG is not administered or it is replaced by another medication.
In the case when hCG has already been administered, the eggs are retrieved and the fresh embryo transfer is cancelled. Instead, the embryos are frozen and transferred at a later date when the ovaries return to normal. If the hyperstimulation is mild, embryo transfer sometimes can still take place. In these cases, strict ultrasound control of the patient’s situation is undertaken in the days immediately following the egg retrieval to assure no unnecessary risks are taken and to avoid danger to the woman’s health.
The risk of multiple pregnancy increases with the number of embryos that are transferred. At present, Spain has the lowest percentage of multiple pregnancies due to Assisted Reproduction Techniques according to data from the European Society of Assisted Reproduction and Embryology (ESHRE). Thanks to excellent implantation rates, we can transfer one single embryo at each transfer and still obtain in a high pregnancy rate.
Ectopic pregnancy is another possible risk. This occurs when an embryo implants outside the uterus, most frequently in the Fallopian tubes. Ectopic pregnancies are slightly higher in women who have undergone Assisted Reproduction Techniques than in those women who conceive spontaneously.
There is a small risk (less than 3%) of haemorrhage, infections, ovarian torsion and complications from anaesthesia.
