In Vitro Fertilization (IVF)

1. What is In Vitro Fertilization (IVF)?

In vitro fertilization (IVF) is a treatment that has helped many women in their desire to be mothers. IVF consists of the union of male (sperm) and female (oocyte) gametes in order to create embryos that will later be transferred to your uterus using the embryo transfer technique.

2. For whom is in vitro fertilization indicated?

In vitro fertilization is an alternative treatment when other fertility treatments have previously failed and in patients with disorders such as:

E

Absence, obstruction or lesion of the tubes.

E

Decrease in the number and / or mobility of sperm or increase in morphological alterations.

E

Moderate or severe endometriosis.

E

Alterations of ovulation.

E

Failures of other treatments (scheduled intercourse, artificial insemination).

E

Advanced age.

E

In others...

Phases of IVF

In vitro fertilization treatment consists of different phases

1. Ovarian Stimulation

In the natural process of a female menstrual cycle, women produce a single oocyte (egg) monthly. Through the administration of medication, what we are looking for in this first phase of In Vitro Fertilization is to stimulate the ovary and induce the production of more oocytes. If the creation of many oocytes is achieved, the possibility of gestation is greater as more embryos can be obtained. We control the evolution of this process through periodic ultrasound checks, and sometimes blood tests.

2. Follicular puncture

When it is verified by ultrasound that the follicles have reached the appropriate diameter and number, the follicular puncture is programmed. Approximately 36 hours before the puncture, an injection of hCG hormone that induces oocyte maturation should be administered in a similar way as it occurs in the natural cycle. The ovarian or follicular puncture consists in the extraction of the follicular fluid that is in the oocytes by means of a surgical intervention that is carried out in the operating room, by means of sedation and whose duration is usually not more than 15 minutes. Although it is not usual, if after the puncture you feel any discomfort, you can call the clinic to be informed of what steps to follow.

3. Embryo culture and in vitro fertilization

Once the oocytes are extracted by puncture, and already with your partner’s sperm, the oocyte is fertilized in the laboratory by using two techniques: conventional IVF or intracytoplasmic sperm injection (ICSI)

4. Embryo transfer

Embryo transfer is the last and decisive step in the process to get your pregnancy through In Vitro Fertilization. It is a crucial phase of treatment.

The process is very simple although, like the puncture, it is done in the operating room. The embryos are placed with a specific catheter, made with a very flexible material, so as not to damage the walls of the uterine cavity, and you do not need to be sedated because it is not a painful process.

After embryo transfer, you remain at rest for about half an hour. Then you can resume your daily activity, always in moderation. The remaining embryos of the process will be frozen, in order not to repeat the process of ovarian stimulation and follicular puncture again, in case you do not get pregnant in the first cycle of IVF.

5. Post embryo transfer process

About two weeks after embryo transfer, the pregnancy test is performed. Two possibilities are contemplated after embryo transfer:

OPTION 1: You get pregnant:

In Vitro Fertilization treatment has been successfully completed. From this moment, we discharge you and continue with a gynecological follow-up of pregnancy; with our specialized gynecologists.

OPTION 2: You do not get pregnant:

When the cycle does not end with pregnancy, the most important thing is not to lose hope and keep calm. That you do not get pregnant in the first cycle of IVF does not mean that you cannot do it in later cycles. The two options for this possibility are:

  1. If you have frozen embryos, we perform a cryotransfer, that is, embryos that have been cryopreserved are transferred to your uterus as in the first IVF cycle. It is worth mentioning that preparing the uterus for a transfer of frozen embryos is much simpler, since it is not necessary to repeat the process of ovarian stimulation and follicular puncture.
  2. If you do not have frozen embryos, we make a second attempt or second cycle, starting the process of IVF from scratch.

2. Follicular puncture

When it is verified by ultrasound that the follicles have reached the appropriate diameter and number, the follicular puncture is programmed. Approximately 36 hours before the puncture, an injection of hCG hormone that induces oocyte maturation should be administered in a similar way as it occurs in the natural cycle. The ovarian or follicular puncture consists in the extraction of the follicular fluid that is in the oocytes by means of a surgical intervention that is carried out in the operating room, by means of sedation and whose duration is usually not more than 15 minutes. Although it is not usual, if after the puncture you feel any discomfort, you can call the clinic to be informed of what steps to follow.

4. Embryo transfer

Embryo transfer is the last and decisive step in the process to get your pregnancy through In Vitro Fertilization. It is a crucial phase of treatment.

The process is very simple although, like the puncture, it is done in the operating room. The embryos are placed with a specific catheter, made with a very flexible material, so as not to damage the walls of the uterine cavity, and you do not need to be sedated because it is not a painful process.

The remaining embryos of the process will be frozen, in order not to repeat the process of ovarian stimulation and follicular puncture again, in case you do not get pregnant in the first cycle of IVF.

How many cycles can you do?

In Oyala Fertility Center we will guide you in the most appropriate way to perform the following treatment. We will assess how the first cycle has gone and if the assessment is correct then we will advise you to repeat the In Vitro Fertilization cycle.
