In Vitro Fertilization

The objective of this treatment is to obtain an adequate quantity of ovules; after controlled stimulation of the ovaries, later the eggs will be fertilized in an Assisted Reproduction laboratory with the couple's semen, under state-of-the-art technology and with highly trained personnel, thereby increasing the probability of pregnancy.

​

This method is recommended in the following cases:

• Women older than 36 years.

• Failures in artificial inseminations.

• blocked tubes.

• endometriosis.

• ovarian cancer.

• Vasectomy.

• Severe seminal alteration.

• Absence of sperm in the semen.

Stages of In Vitro Fertilization

 

1.-Ovarian stimulation

Which begins on the second day of menstruation with injectable hormone drugs * (Gonadotropins) for about 10 days at doses calculated according to their weight, height, and follicular endowment, to achieve multiple ovulation (about 6 to 10 follicles). Throughout this process, the woman is likely to experience tension, stress, and anguish. For this reason, at the clinic, we have an Emotional Support Program (PAE), through which the woman and her partner receive support and emotional information throughout their treatment so that they experience it with the greatest physical and emotional well-being possible.

​

2.- Follicular monitoring and serum estradiols

After two days of application of the indicated medication, a blood sample is taken from the woman to measure her levels of Estradiol (female hormone) and determine if she should continue with the same dose, increase it or decrease it. An ultrasound is not performed at this time because there are no significant changes in the ovaries.

Several ultrasounds and blood samples are taken every other day, at the discretion of your doctor, until follicular maturation and adequate Estradiol blood levels are reached. During this period of treatment, you can go to the clinic a few minutes before to help you eliminate physical and emotional stress.

​

3.- Ovular capture

The maturation of the ovules ends with the last injection, which favors the ovulation process, also known as "shot" Ovular capture is scheduled 36 hours after the application of said injection. On the day of ovulation capture, the woman must go to the center fasting for at least 8 hours, without makeup, perfume, antiperspirant, or any other substance that gives off odors; upon arrival receive a relaxing massage of approx. 20 minutes, so that you are as relaxed as possible. Before starting the procedure, a vein in the arm is channeled with a solution and it will be prepared for a short and superficial anesthesia to be able to capture the ovules. Ovular capture is the procedure by which eggs are extracted from the body. It lasts approximately 15 to 20 minutes. The doctor uses a fine ultrasound-guided needle that crosses the wall of the vagina until it reaches the ovary. In each ovary it aspirates the contents of the follicles, thus obtaining the ovules. This procedure is performed in the operating room.

​

4.- In Vitro Fertilization

While the eggs are being captured, the couple obtains a semen sample by masturbation. In the In Vitro Fertilization laboratory, fertilization is carried out, which can be done in two ways: a) Conventional: previously prepared ovules and spermatozoa are placed in a glass container for fertilization to occur. B) ICSI (Intracytoplasmic Micro Injection): This technique consists of injecting sperm into the egg using a microneedle to facilitate fertilization. It is used when the number of motile and normal spermatozoa is too low to ensure fertilization. Once this occurs, the development of the embryos obtained is observed. The couple can check the status and development of their embryos daily.

​

5.- Embryo Transfer

Embryo transfer consists of depositing one or two embryos into the woman's uterus vaginally through a thin cannula. This procedure generally takes place 3 to 6 days after ovulation capture, depending on the development of the embryos. It is important not to apply any chemical substances that give off odors or that could harm the embryos, such as makeup or antiperspirant. This process does not require anesthesia and takes approximately 20 minutes.

​

6.- Pregnancy test

It is carried out 12 days after the embryo transfer, using a quantitative determination of the pregnancy hormone.
